Opis:
Fear is one of the factors that is most life threatening. it causes psychogenic illness, pro- ducing tension in the mind and in addition, distorting a person’s morals. The ambition of this paper is to outline the evolutionary processes that throughout the history of the human race have influenced the development of human thought, feeling, effect, and therefore fear as well. it further describes fear not just as genetic information, but also as information mediated by the social community and groups, as a phenomenon influenced by cultural environment.

Opis:
The article presents the current state of evolutionary economics against the backdrop of changes related to the potential use of the achievements of other social sciences, in particular psychology, as well as dynamically developing neuroscience. The article suggests a synthesis of evolutionary and behavioural economics concepts as a logical consequence of evolutionary cooperation processes in social sciences. Interdisciplinary initiatives create new perspectives on generation synergy effects for all participants. Contemporary evolutionary economists present the nature of ongoing innovation-driven economic change as a long evolutionary process. The main creator of the econosphere as a global system is a man–entrepreneur who is also the result of evolutionary processes. For this reason evolutionary economics should take into account the results of behavioural economics’ research based on modern psychology and neuroscience. The cornerstone of evolutionary and behavioural economics synthesis are the theories of Adam Smith which should be regarded as his holistic intellectual heritage.

evolutionary neural networks
Opis:
Assembler Encoding represents a neural network in the form of a simple program called Assembler Encoding Program. The task of the program is to create the so-called Network Definition Matrix, which maintains all the information necessary to construct a network. To generate the programs and, in consequence, neural networks, evolutionary techniques are used. One of the problems in Assembler Encoding is to determine an optimal number of neurons in a neural network. To deal with this problem a current version of Assembler Encoding uses a solution that is time consuming and hence rather impractical. The paper proposes four other solutions to the problem mentioned. To test them, experiments in a predator-prey problem were carried out. The results of the experiments are included at the end of the paper.

NEO-EVOLUTIONARY PARADIGM
Opis:
The objective of this article is an analysis of the perceptive consequences of the neo-evolutionary paradigm in social studies from the point of view of human resource management in its decisional rationality aspect. The results of socio-biological, cognitive, evolutionary psychology, and behavioral economics studies have, to date, been largely ignored in management. Today, however, is seeing the laying of the structure of a new neo-evolutionary paradigm in social studies that will most probably lead to an enlightening of the field of study of human behavior, including in the realm of organization and management. Such a far-reaching change in the cognitive perspective shall also usher in significant consequences in human resource management.

Opis:
The paper deals with the application of Parallel Evolutionary Algorithms (PEA) and the Finite Element Method (FEM) in shape optimization of heat radiators. The fitness function is computed with the use of the coupled thermoelsticity modelled by MARC/MENTAT software. The geometry, mesh and boundary conditions are created on the basis of a script language implemented in MENTAT. In order to reduce the number of design parameters in evolutionary algorithms, the shape of the structure is modelled by Bezier curves. Numerical examples for some shape optimization are included.
W pracy przedstawiono zastosowanie algorytmów ewolucyjnych oraz metody elementów skończonych (MES) w optymalizacji kształtu radiatorów. Zastosowano algorytm ewolucyjny, w którym funkcja celu wyznaczana jest w sposób równoległy, więc obliczenia przeprowadzane mogą być na wielu komputerach wieloprocesorowych. Tego typu podejście znacznie skraca czas obliczeń w porównaniu do sekwencyjnego algorytmu ewolucyjnego. Wartość funkcji celu wyznaczana jest na podstawie rozwiązania zagadnienia termosprężystości z wykorzystaniem oprogramowania MES MARC/MENTAT. Przy rozwiązywania zagadnienia bezpośredniego uwzględniany jest radiacyjny strumień ciepła. Wyznaczenie stref zacieniania, niezbędnych do jego wyznaczenia, realizowane jest również za pomocą procesora MENTAT. W celu zmniejszenia liczby zmiennych projektowych przy modelowaniu geometrii radiatora wykorzystano krzywe Beziera. Ponadto praca zawiera przykłady numeryczne optymalizacji dla różnych konfiguracji warunków brzegowych.

Opis:
In this paper it is being argued that music might be regarded as a adaptive human behavior in the light of the evolutionary process. The author recalls here the NAPS theory of music according to which music does not prolong the existence of humanity but it might use one or many channels related to feeling pleasure which had evolved to strengthen adaptive behavior. The article recalls examples of theoreis of musical evolution connec ted to such issues as sexual choices, social integrity, development of perception, development of movement abilities, group effort, reduction of conf lict of interests, safe time consumption and communication between generations. All this evidence is being here regarded through archeological, anthropological and etological context. The conclusion of this paper is based on two assumptions. The first one is the notion that our mood is regulated through conversation and being with a friendly human. The other says that music takes and important place in this mood regulation.

Opis:
Tadeusz Garbowski (1869-1940) was an original thinker, preoccupied with zoology and ethology, and also the philosophy of nature. First, he worked in Vienna where he got his PhD and then (1898) he moved to Cracow and continued his studies at the Jagiellonian University. He developed his epistemological concepts with reference to natural sciences, mainly to evolutionary biology. With his naturalistic evolutionism and evolutionary epistemology he was ahead of concepts of Lorentz and, to some extent, K. R. Popper. Although he did not use the concept of teleonomy, which in our times was popularized by a French researcher F. Jacob, he interpreted spiritual culture created by a man as a kind of adaptation in the evolutionary sense. The concept of homogenis makes the core of Garbowski's epistemology and methodology. Garbowski claimed that the aim of science and philosophy is discovering and expressing the truth. The truth is homogenous and undivided, and experiment at the base of philosophy is also uniform and homogenous. Homogenism is a radical monism with naturalistic background.

Opis:
Contemporary theological and philosophical ethicists posit the ability of human beings to achieve solidarity with one another on a large social scale. However, many people, including politicians and key decision-makers, have argued that this kind of solidarity is not possible. Several current anthropological theories, such as those undergirding neoclassical economic theory and the realist school of international relations, maintain that individuals and nations essentially act in their own interest. “Selfish” human nature discounts the possibility of broad and sustained solidarity. This paper addresses the question of whether or not human nature contains the potential and impulse to practice solidarity to ever greater degrees. First, it briefly defines solidarity. Next it summarizes competing views among biologists on the consistency between human nature and solidarity. Then it turns to the work of renowned evolutionary biologists David Sloan Wilson and Frans de Waal to demonstrate that solidarity may be more consistent with human nature than many acknowledge.

Opis:
The origin of major morphological innovations poses a major problem for macroevolutionary biologists. Such innovations appear to be overwhelmingly concentrated early in the history of major clades; subsequent evolution involves elaboration and variation on these early themes. Although confirmation of this pattern requires morphometric techniques only now being developed, it seems too firmly established to be an illusion. A variety of explanations have been advanced for the extensive morphologic innovation during the Cambrian radiation, including the ecospace hypothesis which relies on more extensive ecospace, and a variety of genomic hypotheses ranging from a more rapid rate of real or apparent mutation, to novel types of genetic change, or novel effects within a more plastic developmental system. Recently some theorists have suggested the inherent properties of complex dynamic systems are a sufficient explanation. However, most discussions have emphasized the ecosystem and genomic hypotheses. These have proven difficult to disentangle because no unique predictions about expected patterns have been proposed, but I suggest here phylogenetic tests which do discriminate between these possibilities. There is a curious distinction between the empty ecospace hypothesis and one variant of the developmental hypothesis: Under the former, extensive morphologic innovation should be possible whenever extensive ecospace becomes available. The constraints on innovation are atemporal and extrinsic. In contrast, under the second scenario the formation of developmental systems itself constrains further innovation. Thus the concentration of innovation early in the history of clades may stem from irreversible changes associated with the origin, rather than subsequent modification, of development.

Zespół Kevina Lalanda przedstawił liczne argumenty przemawiające za rozszerzoną syntezą ewolucyjną. W tym artykule analizuję kluczową dla tych uczonych koncepcję dwustronnej przyczynowości. Koncepcja ta przywoływana jest w wielu argumentach na rzecz przyjęcia rozszerzonej ewolucjonistycznej ramy pojęciowej, niewielka część tych argumentów jest jednak jasno sprecyzowana. Objaśniam tutaj tę koncepcję i przedstawiam trzy linie argumentacji, w których jest ona wykorzystywana. Wskazuję na to, w których punktach sceptycy mogą podważać — i podważają — te argumenty, jak również zwracam uwagę na główne, w moim przekonaniu, problemy empiryczne, eksplanacyjne i metodologiczne związane z tą koncepcją.
Kevin Laland and colleagues have put forward a number of arguments motivating an extended evolutionary synthesis. Here I examine Laland et al.’s central concept of reciprocal causation. Reciprocal causation features in many arguments supporting an expanded evolutionary framework, yet few of these arguments are clearly delineated. Here I clarify the concept and make explicit three arguments in which it features. I identify where skeptics can — and are — pushing back against these arguments, and highlight what I see as the empirical, explanatory, and methodological issues at stake.

Opis:
The phenomenon of globalization, which is well known in the economy, can nowadays be observed also in the area of science. It is based on the fact that more and more scientific disciplines are applying the same explanatory principle, namely the theory of evolution. Therefore, every development, including that of man, according to the pattern of genetic reproduction, takes place on the basis of natural selection. With psychological properties, mental abilities and social behaviours, which are eloquently referred to as “memes”, it is as with genes: only those that are better, stronger, more capable of surviving will survive after accidental changes and only they will be passed on. In short, reproduction regulates and controls human behaviour. Such a way of thinking and explanation can be found today in many publications on sociobiology and evolutionary psychology. Even if they present many new details, they pay tribute to the old human desire to explain everything in a simple way, according to the same scheme. The same expectation towards science was expressed by E. Haeckel in the 19th century and J. Monod in the 20th century. However, when these two biologists explained man as a whole based on the theory of evolution, they admitted that they referred to philosophy, to which contemporary representatives of sociobiology and evolutionary psychology cannot or do not want to confess.

Opis:
The paper presents the application of a memetic algorithm to searching for the optimal sequence of the assembly of parts. Such approach is based on the use of an algorithm connecting two methods of global and local search in order to increase the effectiveness of the conducted optimisation process. Based on a proper representation of assembly sequences and a set of geometrical, topological and technological constraints, connected with the attributes of a product, it is possible to create an evolutionary model. Through proper control of the evolution process in a model, based on the appropriate selection of parameters, it is possible to achieve good results in a short period of time. Although the evolutionary algorithm does not guarantee the obtaining of optimal solutions, it has been proven, based on sample simulations, that such solutions are obtained in a repeated manner. The application of the presented evolutionary approach enables creating fast assembly sequence planning tools, indispensable in tactical planning and operational control of manufacturing processes.

We describe an implementation of EDRL-MD system in the cluster of multiprocessor machines connected by Fast Ethernet. Our approach consists in a distribution of the learning set into processors of the cluster. The evolutionary algorithm uses a master-slave model to compute the fitness function in parallel. The remiander of evolutionary algorithm is executed in the master node. The experimental results show, that for large datasets our approach is able to obtain a significant speed-up in comparison to a single processor version.

Opis:
This article describes two evolutionary methods for dividing a graph into densely connected structures. The first method deals with the clustering problem, where the element order plays an important role. This formulation is very useful for a wide range of Decision Support System (DSS) applications. The proposed clustering method consists of two stages. The first is the stage of data matrix reorganization, using a specialized evolutionary algorithm. The second stage is the final clustering step and is performed using a simple clustering method (SCM). The second described method deals with a completely new partitioning algorithm, based on the subgraph structure we call α-clique. The α-clique is a generalization of the clique concept with the introduction of parameter α, which imposes for all vertices of the subgraph the minimal percentage (α*100%) of vertices of this subgraph that must be connected with vertices of this α-clique. Traditional clique is an instance of α-clique with α = 1. Application of this parameter makes it possible to control the degree (or strength) of connections among vertices (nodes) of this subgraph structure. The evolutionary approach is proposed as a method that enables finding separate α-cliques that cover the set of graph vertices.

Opis:
The central goal of the presented article is to show that the type of rationality proper to the method of the contemporary sciences yields a unique conceptual environment in which the spirit of rationality instilled to the theological thought by its encounter with the Greek philosophy finds its natural expansion. At the outset, the origins of the Greek rationality in the Ionian school of philosophy are briefly discussed in order to illuminate their adequacy for the exposition and defense of doctrine in the times of the early Church Fathers. Next, the specificity of the scholastic method of St. Thomas Aquinas briefly surveyed to indicate the nature of the unique harmony between faith and reason achieved by the Angelic Doctor. In the following step, the role of rationality in theology is gleaned through negative examples of its elimination as evident in nominalism and the subsequent Lutheran intervention. This is followed by a short discourse into of the origins and the specificity of the contemporary scientific method with particular emphasis on the method’s unique potential to expand and deepen the Greek rationality. Finally, a case study of the evolutionary theology is offered in which the implementation of the dynamic (evolutionary) picture of the Universe as the conceptual foundation opens up new and profound ways of understanding the Universe’s meaning and the meaning of man in particular. Thus the spirit of the hellenistic rationality in theology is not only preserved but also significantly enhanced.

The work is devoted to the identification of microstructure parameters of a porous body under thermal and mechanical loads. The goal of the identification is to determine the parameters of the microstructure on the basis of measurements of displacements and temperatures at the macro level. A two-scale 3D coupled thermomechanical model of porous aluminum is considered. The representative volume element (RVE) concept modeled with periodical boundary conditions is assumed. Boundary-value problems for RVEs (micro-scale) are solved by means of the finite element method (FEM). An evolutionary algorithm (EA) is used for the identification as the optimization technique.

Opis:
Niching is a group of techniques used in evolutionary algorithms, useful in several types of problems, including multimodal or nonstationary optimization. This paper investigates the applicability of these methods to evolutionary multi-agent systems (EMAS), a hybrid model combining the advantages of evolutionary algorithms and multi-agent systems. This could increase the efficiency of this type of algorithms and allow to apply them to a wider class of problems. As a starting point, a simple but flexible EMAS framework is proposed. Then, it is shown how to extend this framework in order to introduce niching, by adapting two classical niching methods. Finally, preliminary experimental results show the efficiency and the simultaneous discovery of multiple optima by this modified EMAS.

The transformation process in the countries which is associated with changes in the size structure of enterprises and capital ownership, affects the economic processes, and hence also the innovative activity in the industry. That is why the main objective of the study was to look for evolving in time determinants of size class and ownership structure of industrial enterprises on their innovative activity in within the Lower Silesia industrial system, and ultimately determine the limits of the assumptions of the master structure of regional innovation networks, which take into account the specificity of the particular region. The hypothesis of the research was formulated as an assertion that innovative activity in territorial industrial systems and in their relations with the environment is significantly determined by the influence of the size and structure of companies evolving over time. Empirical and exemplificative sphere of this paper was based on a case study of Lower Silesia Voivodeship. The study was performed twice on the basis of standardized questionnaire on a group of 492 industrial enterprises in 2004−2006, and 761 subjects in the years 2010−2012. The methodological part of the analyzes was based on the theory of probability, where the dependent variable had the binary value. In the paper logistic regression is used, of which the greatest advantage is the ability to analyze and interpret the results from using the methods which are similar to the classic method of regression, on the basis of the selection scheme of the convergent variables and hypothesis testing. The results of research show that the diversity of innovative activity in the Lower Silesia region, taking into account the structure and size of businesses in the industrial system, indicates their temporal evolution and, consequently, different habits in the tested group of enterprises. Conclusions of the research suggest that these interactions are often dependent on the current stage of development of the industrial system. According to the system and evolutionary theory, responsibility for the increase of the potential and improvement of technological competitiveness of the region, will move from large business entities, through the medium towards small enterprises, and from the point of view of the nature of ownership: foreign entities towards mixed, but much slower. Owners of domestic micro-enterprises in the Polish conditions are characterized by extensive reticence in taking risks arising from innovative activities.

As a testbed for the methods a variant of the predator–prey problem with Autonomous Underwater Vehicles (AUV) operating in an environment with the sea current was used. In the experiments, the task of vehicles–predators controlled with evolutionary neural networks was to capture a vehicle–prey behaving according to a simple deterministic strategy. All the experiments were carried out in simulation, and in order to simplify calculations in the two–dimensional environment – AUVs moved on a horizontal surface under the water.

Opis:
The paper discusses the influence of learning on evolutionary processes. In biological sciences it is a well-known fact that the rate of evolution can be effected by learning and the same phenomena can also be observed in artificial evolutionary systems, however, their nature is still not sufficiently well understood. In the paper the influence of constant learning on the rate of evolution is examined. The constant learning is a kind of learning during which the genotype of the individual being taught is moved toward the global optimum over a constant value. If the fitness function is monotonic, it can be concluded from the mathematical theory that such kind of learning should decelerate evolution. However, this fact is highly counterintuitive and for this reason it should be proved by numerical experiments. In the article the results of numerical simulations are presented. They prove that evolution is indeed decelerated by learning in case of the sigmoid fitness function. Moreover, two cases of constant learning were examined in the paper. These are the positive and negative constant learning. It was demonstrated that in the case of the negative constant learning the evolution was decelerated to a larger extent than in the case of the positive constant learning. The obtained results can help explain certain phenomena concerning the impact of learning on the evolution both in natural and artificial evolutionary systems.

Timetabling problems are often difficult and time-consuming to solve. Most of the methods of solving these problems are limited to one problem instance or class. This paper describes a universal method for solving large, highly constrained timetabling problems in various domains. The solution is based on an evolutionary algorithm framework and employs tabu search to quicken the solution finding process. Hyper-heuristics are used to establish the algorithm's operating parameters. The method has been used to solve three timetabling problems with promising results of extensive experiments.

The article presents the use of an evolutionary algorithm for determining the shape of the guy rope sag of a steel smokestack. The author excludes the analysis of the operation of the rope, and discusses only the problem of determining parameters of the function of the adaption of the rope sag curve into empirical data, obtained by the geodetic method. The estimation of parameters of the curve and the characteristics of the accuracy of its adaption into experimental data were carried out by means of an evolutionary algorithm with the use of an evolutionary strategy (μ+λ). The correctness of the strategy presented in the paper, as an instrument for searching for a global minimum of a criterion function, has been presented using as an example the minimisation of a certain two dimensional function and the estimation of parameters of an ordinary and orthogonal regression function. Previous theoretical analyses have also been used for determining parameters of the guy rope sag of a steel smokestack, which is measured periodically. In addition approximate values of the pull forces in the guy ropes have been calculated.

Opis:
The conditions of imprisonment in Polish prisons make it difficult to achieve the goals of penitentiary social rehabilitation. Adaptation to prison conditions, which occurs especially as a result of long-term stay in a closed-type prison, results in disadaptation to the conditions in freedom and usually leads to degradation of the prisoner’s personality. An important reason for this is the unnaturalness of a environment. It is almost totally incompatible with human nature due to its radical difference from the environment in which the human mind evolved. In the article, the authors present an initial evolutionary oriented diagnosis of environmental factors responsible for low effectiveness of penitentiary social rehabilitation. The article contains also suggestions of modifications that may increase the level of its effectiveness.

This article presents the use of a multi‐population distributed evolutionary algorithm for path planning in navigation situation. The algorithm used is with partially exchanged population and migration between independently evolving populations. In this paper a comparison between a multi‐population and a classic single‐population algorithm takes place. The impact on the ultimate solution has been researched. It was shown that using several independent populations leads to an improvement of the ultimate solution compared to a single population approach. The concept was checked against a problem of maritime collision avoidance.

Assembler Encoding (AE) represents Artificial Neural Network (ANN) in the form of a simple program called Assembler Encoding Program (AEP). The task of AEP is to create the socalled Network Definition Matrix (NDM) including all the information necessary to construct ANN. AEPs and in consequence ANNs are formed by means of evolutionary techniques. To make AE an effective tool for creating ANNs it is necessary to appropriately organize all the evolutionary processes responsible for generating AEPs, i.e., it is necessary to properly select values of different parameters controlling the evolutionary process mentioned. To determine optimal conditions of the evolution in AE, experiments in a predator-prey problem were performed. The results of the experiments are presented at the end of the paper.
Kodowanie asemblerowe jest metodą wykorzystującą metody ewolucyjne do tworzenia sieci neuronowych. W kodowaniu asemblerowym sieci neuronowe ewoluują w wielu oddzielnych populacjach. Stworzenie pojedynczej sieci neuronowej wymaga połączenia elementów pochodzących z różnych populacji. Aby sieci neuronowe tworzone w ten sposób były wysokiej jakości konieczne jest odpowiednie sterowanie ewolucją w każdej populacji. Artykuł prezentuje wyniki badań, których głównym celem było określenie zasad prowadzenia ewolucji w Kodowaniu Asemblerowym.

Opis:
In this paper we present a complex strategy for the solution of ill posed, in-verse problems formulated as multiobjective global optimization ones. The strategy is capable of identifying the shape of objective insensitivity regions around connected components of Pareto set. The goal is reached in two phases. In the first, global one, the connected components of the Pareto set are localized and separated in course of the multi-deme, hierarchic memetic strategy HMS. In the second, local phase, the random sample uniformly spread over each Pareto component and its close neighborhood is obtained in the specially profiled evolutionary process using multiwinner selection. Finally, each local sample forms a base for the local approximation of a dominance function. Insensitivity region surrounding each connected component of the Pareto set is estimated by a sufficiently low level set of this approximation. Capabilities of the whole procedure was verified using specially-designed two-criterion benchmarks.
Artykuł prezentuje złożoną strategię rozwiązywania źle postawionych problemów odwrotnych sformułowanych jako wielokryterialne zadania optymalizacji globalnej. Opisana strategia umożliwia identyfikację obszarów niewrażliwości funkcji celu wokół spójnych składowych zbioru Pareto. Cel jest osiągany w dwu etapach. W pierwszym z nich — globalnym — składowe spójne zbioru Pareto są lokalizowane i separowane przy pomocy wielopopulacyjnej hierarchicznej strategii memetycznej HMS. W etapie drugim — lokalnym — przy użyciu specjalnie sprofilowanego procesu ewolucyjnego wykorzystującego operator selekcji wyborczej z wieloma zwycięzcami produkowana jest losowa próbka rozłożona jednostajnie na każdej składowej i jej bliskim otoczeniu. Finalnie każda lokalna próbka jest użyta jako baza do zbudowania lokalnej aproksymacji funkcji dominacji. Zbiory poziomicowe tej aproksymacji dla odpowiednio niskich poziomów stanowią przybliżenie zbiorów niewrażliwości wokół składowych spójnych. Możliwości strategii zostały zweryfikowane przy użyciu specjalnie zaprojektowanych dwukryterialnych funkcji testowych.

Opis:
In this paper a new approach to evolutionary controlled creation of electronic circuit connection topology is proposed. Microwave circuits consisting of a tree like connection of ideal transmission lines are considered. Assuming that a reasonable number of transmission lines in a tree network ranges from 10 to 100, the number of connection combinations is immense. From the engineering practice comes the hypothesis that any device can be decomposed into some functional building blocks consisting of one to dozen transmission lines. The variety of linking combinations in a tree with a limited depth is confined to hundreds or thousands of shapes. Therefore we can decrease the dimensionality of research space, applying evolution to building blocks only. Evolutionary algorithm (EA) which processes simultaneously the population of λ functional blocks and population of ž circuits is proposed. A μ, λ selection scheme with tournament together with specific encoding of solutions, and custom operators is implemented. The μ, λ, α EA was tested on an example of the design of a microwave transistor matching circuit.

Opis:
The evolutionary approach called Scatter Search, and its generalized form called Path Relinking, have proved unusually effective for solving a diverse array of optimization problems from both classical and real world settings. Scatter Search and Path Relinking differ from other evolutionary procedures, such as genetic algorithms, by providing unifying principles for joining solutions based on generalized path constructions (in both Euclidean and neighborhood spaces) and by utilizing strategic designs where other approaches resort to randomization. Scatter Search and Path Relinking are also intimately related to the Tabu Search metaheuristic, and derive additional advantages by making use of adaptive memory and associated memory-exploiting mechanisms that are capable of being adapted to particular contexts. We describe the features of Scatter Search and Path Relinking that set them apart from other evolutionary approaches, and that offer opportunities for creating increasingly more versatile and effective methods in the future.

Opis:
The artification hypothesis presented in this paper is based on the assumption that small children have the ability not ju st to persuade other to give them physical safety but also to initiate social bonds and emotional interaction. Thus the interactions between the child and mother are adaptive in their character and as such they were not considered by evolutionary psychologists. The other factor of artification is the ritualization of those interactions. The article delivers many examples of proto aesthetic actions and artifications stressing out also the religious aspect of the phenomenon. The author concludes with the notion that artification and aesthetic agency are adaptive as such and they were just as important in the human evolution as nonverbal information transmission.

Zasady unifikujące Nowoczesnej Syntezy biologii ewolucyjnej są obecnie podważane przez Rozszerzoną Syntezę Ewolucyjną. Ta ostatnia, jak dotąd, nie zapewniła jednak własnych zasad unifikujących, przez co wielu naukowców wątpi, czy rzeczywiście stanowi ona oryginalną syntezę biologii ewolucyjnej. W niniejszym artykule za zasadę unifikującą Rozszerzonej Syntezy Ewolucyjnej uznaję koncepcję ewolucyjnej teleonomii (jest to koncepcja Ernsta Mayra zastosowana do samych procesów ewolucyjnych). Dostarczę ponadto konkretnych przykładów pokazujących, że współczesne badania, biorąc za podstawę zasady unifikujące Nowoczesnej Syntezy, prowadzą w ślepą uliczkę. Można temu zaradzić dzięki przyjęciu Rozszerzonej Syntezy Ewolucyjnej wraz z ewolucyjną teleonomią jako zasadą unifikującą.
Many people underestimate the effect that unifying principles have on the study of biology. Unifying principles are used to provide simplifying assumptions to complex problems, which allow them to be effectively tackled by the tools at hand. However, erroneous unifying principles will generate simplifying assumptions that lead towards mischaracterizations of problems which inevitably lead to invalid conclusions. The unifying principles of the current Modern Synthesis of evolution are presently being challenged by the Extended Evolutionary Synthesis. However, the Extended Evolutionary Synthesis has so far failed to provide unifying principles of its own, which has caused many to question whether or not the Extended Evolutionary Synthesis is indeed a unique synthesis of evolutionary biology. Here, the concept of evolutionary teleonomy (Ernst Mayr’s concept of teleonomy applied to evolutionary processes themselves) is identified as a unifying principle of the Extended Evolutionary Synthesis. Additionally, specific examples are provided where modern research has been led astray by the unifying principles of the Modern Synthesis which would have been corrected by applying the Extended Evolutionary Synthesis with the unifying principle of evolutionary teleonomy.

Opis:
The paper presents the method for the optimal synthesis of four-link mechanism generating open/closed paths with time prescription. Although the method is suitable for both closed and open paths, it enables decreasing the number of design parameters describing dimensions, orientation and position of a path generator. Compared to the methods presented in the references, this is a one-phase synthesis method; although the number of design parameters is reduced, the method does not require affine transformations to be performed on the synthesised mechanism. The effectiveness of the method is discussed based on examples of three paths, with two taken from the literature.

The paper deals with the multiobjective and multiscale optimization of heterogeneous structures by means of computational intelligence methods. The aim of the paper is to find optimal properties of composite structures in a macro scale modifying their microstructure. At least two contradictory optimization criteria are considered simultaneously. A numerical homogenization concept with a representative volume element is applied to obtain equivalent macro-scale elastic constants. An in-house multiobjective evolutionary algorithm MOOPTIM is applied to solve the considered optimization tasks. The finite element method is used to solve the boundary-value problem in both scales. A numerical example is attached.

Pareto front
Opis:
In this paper new multicriteria design optimization methods are discussed. These methods are evolutionary algorithm based medhods, and their aim is to make the process of generating the Pareto front very effective. Firstly, the multistage evolutionary algorithm method is presented. In this method, in each stage only a bicriterion optimization problem is solved and then an objective function is transformed to the constrain function. The process is repeatedtill all the objective functions are considered. Secondly, the preference vector method is presented. In this method, an evolutionary algorithm finds the ideal vector. This vector provides the decision maker with the information about possible ranges of the objective functions. On the basis of this information the decision maker can establish the preference vector within which he expects to find a preferred solution. For this vector, a set of Pareto solutions is generated using an evolutionary algorithm based method. Finally, the method for selecting a representative subset of Pareto solutions is discussed. The idea of this method consists in reducing the set of Pareto optimal solutions using the indiscrenibility interval method after running a certain number of generations. To show how the methods discussed work each of them in turn is applied to solve a design optimization problem. These examples show clearly that using the proposed methods the computation time can be reduced significantly and that the generated solutions are still on the Pareto front.
W artykule przedstawiono nowe metody optymalizacji wielokryterialnej w projektowaniu technicznym. Metody te oparte są na algorytmach ewolucyjnych, a ich celem jest znaczne zwiększenie efektywności procesu generowania rozwiązań Pareto optymalnych. Najpierw zaprezentowano metodę wieloetapowego algorytmu ewolucyjnego. W metodzie tej na każdym etapie realizowany jest jedynie problem optymalizacji dwukryterialnej, po rozwiązaniu którego jedna z funkcji celu jest przekształcana do postaci ograniczenia. Proces ten jest powtarzany aż do momentu rozpatrzenia wszystkich funkcji celu. Następnie omówiono metode wektora preferencji. W metodzie tej w pierwszym etapie algorytm ewolucyjny znajduje wektor idealny. Wektor ten dostarcza decydentowi informacji o możliwym zasięgu wszystkich funkcji celu. Na podstawie tej informacji decydent może oszacować wektor preferencji, wewnątrz którego spodziewa się znaleźć preferowane rozwiązanie. Dla tego wektora preferencji generowany jest za pomocą algorytmu ewolucyjnego zbiór rozwiązań Pareto optymalnych. Ostatnią z omawianych metod jest metoda redukcji zbioru rozwiązań Pareto optymalnych po przebiegu założonej liczby generacji realizowanych przez algorytm ewolucyjny. W celu pokazania sposobu działania omawianych metod, kazda z nich została zilustrowana innym przykładem zadania optymalnego projektowania. Przykłady te wskazują, że zaproponowane metody mogą znacząco zredukować czas obliczeń komputerowych nie pogarszając wyników.

Opis:
The Action–Trait theory of human motivation posits that individual differences in predispositional traits of action may account for variance in contemporary purposeful human behavior. Prior research has supported the theory, psychometric properties of scales designed to assess the motive dimensions of the theory, and the utility of these scales to predict an array of behaviors, but this is the first study to evaluate the cross-linguistical invariance of the 15-factor theoretical model. This study evaluated translations of the English language 60-item Quick AIM in 5 samples – Croatian (N = 614), French (N = 246), German (N = 154), Polish (M = 314), and U.S. English (N = 490) – recruited from 4 countries (Croatia, Poland, Switzerland, and the U.S.). Exploratory structural equation modeling (ESEM) supported the theoretical model on which the traits of action are based and scrutinized the measurement invariance (configural, metric, scalar invariance) of the scale across the languages.

Opis:
This paper presents the current stage of the development of EA-MOSGWA - a tool for identifying causal genes in Genome Wide Association Studies (GWAS). The main goal of GWAS is to identify chromosomal regions which are associated with a particular disease (e.g. diabetes, cancer) or with some quantitative trait (e.g height or blood pressure). To this end hundreds of thousands of Single Nucleotide Polymorphisms (SNP) are genotyped. One is then interested to identify as many SNPs as possible which are associated with the trait in question, while at the same lime minimizing the number of false detections. The software package MOSGWA allows to detect SNPs via variable selection using the criterion mBIC2, a modified version of the Schwarz Bayesian Information Criterion. MOSGWA tries to minimize mBIC2 using some stepwise selection methods, whereas EA-MOSGWA applies some advanced evolutionary algorithms to achieve the same goal. We present results from an extensive simulation study where we compare the performance of EA-MOSGWA when using different parameter settings. We also consider using a clustering procedure to relax the multiple testing correction in mBlC2. Finally we compare results from EA-MOSGWA with the original stepwise search from MOSGWA, and show that the newly proposed algorithm has good properties in terms of minimizing the mBIC2 criterion, as well as in minimizing the misclassification rate of detected SNPs.
W artykule przedstawiony jest aktualny stan rozwoju programu EA-MOSGWA - narzędzia służącego do identyfikacji przyczynowych genów w badaniach asocjacyjnych całego genomu (ang. Genome Wide Association Studies, GWAS). Głównym celem tych badań jest określenie tych rejonów chromosomu, które są związane z występowaniem chorób genetycznych (np. cukrzyca, rak) lub wpływają na daną cechę (np. wysokość lub ciśnienie krwi). Sprowadzają się one do przebadania wielu tysięcy polimorfizmów pojedynczego nukleotydu (ang. Single Nucleotide Polymorphisme SNP) i powiązaniu ich (pojedynczych lub grupy SNPów) z przypadkami klinicznymi oraz możliwymi do zmierzenia cechami. Kluczową kwestią jest zidentyfikowanie jak największej liczby przyczynowych SNPów przy jednoczesnej minimalizacji fałszywych odkryć. Program MOSGWA umożliwia detekcje SNPów poprzez wybór zmiennych z użyciem kryterium mBIC2 - zmodyfikowanej wersji Bayesowskiego kryterium informacyjnego Schwarza. MOSGWA stara się zminimalizować mBIC2 przy pomocy metody selekcji Stepwise, podczas gdy EA-MOSGWA wykorzystuje w tym cclu zmodyfikowaną wersję algorytmu ewolucyjnego. W artykule prezentujemy wyniki szeroko zakrojonych badań symulacyjnych, w których możemy porównać wydajność EA-MOSGWA przy użyciu różnych ustawień parametrów. Również bierzemy pod uwagę klasteryzację SNPów, aby złagodzić korekcje wielokrotnego testowania w metodzie mBIC2. Przedstawiamy także porównanie wyników otrzymanych przez EA-MOSGWA z wynikami metody Stepsiwe używanej w programie MOSGWA, aby pokazać że proponowana metoda ma dobre właściwości minimalizacji kryterium mBIC2 oraz minimalizacji wskaźnika fałszywych detekcji.

We interpret the multiprocessor scheduling problem as multi-step problem, where a feedback is given after some number steps. We show that LCS is able to solve scheduling tasks of a parallel program in the two processor system.

This paper tackles the application of evolutionary multi-agent computing to solve inverse problems. High costs of fitness function call become a major difficulty when approaching these problems with population-based heuristics. However, evolutionary agent-based systems (EMAS) turn out to reduce the fitness function calls, which makes them a possible weapon of choice against them. This paper recalls the basics of EMAS and describes the considered problem (Step and Flash Imprint Lithography), and later, shows convincing results that EMAS is more effective than a classical evolutionary algorithm.

We investigated the relationship between borderline symptoms in women and their partner’s desire to continue the relationship and relationship commitment in an aversive living environment using an experimental design. We aimed to highlight the adaptive mechanisms of borderline symptoms, which may materialize in reproductive advantages for women in aversive contexts. We conducted two experiments to test the same hypotheses. In Study 1, online participants were assigned to the experimental group (N = 123). The experimental scenario hypothesized having a relationship with a woman high in borderline characteristics, during an aversive life environment. The control group (N = 118) hypothesized having a relationship with a woman high in borderline characteristics, during normal living conditions. We repeated the same experimental manipulation using a within-subjects design in Study 2 (N = 171). Environmental conditions influenced the desire to end the relationship with women characterized by borderline symptoms; men had a lower desire to end the relationship with their partner in aversive life events than in normal living conditions. Thus, women’s borderline behavioral characteristics may bring mating benefits in aversive living environments.

Than the bioheat diffusion equation under a steady-state condition is solved to determine the temperature distributions inside tumour and surrounding tissues. The heat removal due to the blood circulation is also taken into account. Numerical results are presented for heat generated by ferromagnetic nanoparticles in order to minimize negative effects of radiofrequency radiation.

Opis:
In this paper we report an evolutionary approach to learning Bayesian networks from data. We explain reasons, which advocate such a non-deterministic approach. We analyze weaknesses of previous works and come to conclusion that we should operate in the search space native for the problem i.e. in the space of directed acyclic graphs instead of standard space of binary strings. This requires adaptation of evolutionary methodology into very specific needs. We propose quite new data representation and implementation of generalized genetic operators and then we present an efficient algorithm capable of learning complex networks without additional assumptions. We discuss results obtained with this algorithm. The approach presented in this paper can be extended with the possibility to absorb some suggestions from experts or obtained by means of data preprocessing.

In the paper an effective TDOPTW solution (evolutionary algorithm with local search operators) was presented and applied to generate attractive tours in real public transport networks of Białystok and Athens. The method achieved very high-quality solutions in a short execution time.

The CGA is developed for searching a set of rules describing classes in classification problems on the basis of training examples. The details of the method, such as a schema of coding (a chromosome), and a fitness function are shortly described. The method is independent of the type of attributes and it allows choosing different evaluation functions. Developed method was tested using different benchmark data sets. Next, in order to evaluate the efficiency of CGA, it was tested using the Breast Cancer data set with 10 fold cross validation technique.

The paper proposes a method for robust control system design using evolutionary algorithms. The robust control theory is presented in the introduction [6, 7, 8]. Fig. 1 shows a robust feedback control system in which the plant transfer function is variable. The search for a robust controller transfer function requires the knowledge of functional analysis [6, 7, 8]. Application of genetic algorithms to control system design is common [3, 4]. The method proposed is based on minimisation of the norm given by equation (1.18) with use of genetic algorithms [9]. The exemplary verification of the method was performed for a container ship [10]. The changes of the ship linear transfer function coefficients (see Table 2.1) depend on the rudder angle [11, 12]. Figure 2.1 shows calculation results of three robust controller transfer functions. The minimised norms of equation (1.18) with the obtained results are presented in Fig 2.3. It can be noted that the controller characteristics are the same within the low frequency range because the norm was minimized only for the ship operating frequencies. This effect can also be observed on Nyquist curves shown in Fig. 2.2. The problem was investigated in case of control of production processes [1, 2].

Opis:
Metaphysics, or the knowledge of what there is, has been traditionally placed at the pinnacle of philosophical hierarchy. It was followed by theory of knowledge, or epistemology. Practical knowledge of proper modes of conduct, ethics, came third, followed by aesthetics, treated usually in a marginal way as having to do only with the perception of the beautiful. The hierarchy of philosophical disciplines has recently undergone a substantial transformation. As a result, ethics has assumed a central role. The aim of this paper is to suggest that the hierarchy of philosophical disciplines is not yet complete and that one further step needs to be taken. According to the claim advocated here, it is not metaphysics, epistemology or ethics, but aesthetics that is the first and foremost of all philosophical disciplines. This claim is argued for by references to findings of evolutionary aesthetics, especially to Charles Darwin's idea of sexual selection as elaborated in The Descent of Man. I also argue that Darwinian approach to morality is, and should be, derivable from an Darwinian aesthetics which lies at the core of his conception of sexual selection.

Opis:
Evolutionary economic geography became popular in the late 1990s. The study has developed on the basis of evolutionary economics, which has achieved greater success in explaining phenomena in the microeconomic than in the macroeconomic sphere and it has had non-spatial character. Evolutionary economic geography is an alternative in economic geography and regional planning for static or pseudo-dynamic research. Supporters of evolutionary economic geography, by criticizing among others New Economic Geography by P. Krugman, conduct research with the use of generalized Darwinism, path dependence and complexity theory. In this paper the author discusses the basic approach and assumptions of evolutionary economic geography and its application in regional economy, especially as an answer to the search for ways out of the economic crisis of regions and cities.

Opis:
This paper presents the Necessary-preference-enhanced Evolutionary Multiobjective Optimizer (NEMO), which combines an evolutionary multiobjective optimization with robust ordinal regression within an interactive procedure. In the course of NEMO, the decision maker is asked to express preferences by simply comparing some pairs of solutions in the current population. The whole set of additive value functions compatible with this preference information is used within a properly modified version of the evolutionary multiobjective optimization technique NSGA-II in order to focus the search towards solutions satisfying the preferences of the decision maker. This allows to speed up convergence to the most preferred region of the Pareto-front.

Opis:
This article unravels the tangled threads of argumentation that can be found in public debate over institutional practices. An analysis of letters to the editor (n=1551) written about two contested practices (American Indian mascots and the exclusive teaching of evolutionary theory) uncovers three analytically distinct levels of disagreement in the discourse. In the first level, partisans debate the effects of keeping or eliminating the contested practice. This disagreement over consequences leads to a second disagreement over how the social criteria for adjudicating controversies apply to the situation. This application level sits atop a third foundational level of the discourse where partisans debate the nature of social reality and the definition of the rules.

Opis:
Consonant clusters appear either lexically within morphemes or morphonotactically across morpheme boundaries. According to extant theories, their diachronic dynamics are suggested to be determined by analogical effects on the one hand as well as by their morphological signaling function on the other hand. This paper presents a mathematical model which allows for an investigation of the interaction of these two forces and the resulting diachronic dynamics. The model is tested against synchronic and diachronic language data. It is shown that the evolutionary dynamics of the cluster inventory crucially depend on how the signaling function of morphonotactic clusters is compromised by the presence of lexical items containing their morpheme internal counterparts.

Opis:
This article is a theoretical and conceptual exploration into the study of the dynamics of financial innovations and their consequences in market economies. Drawing upon the works of Schumpeter and Minsky in an institutionalist and evolutionary tradition, the article puts forward the monetary and financial features of the 21st century economies and the recurrent systemic financial instabilities generated within the context of the financialization process. It then calls for alternative regulatory reforms capable of leading to sustainable economic development. The originality of the analysis lies in the fact that the micro-dynamics of innovations may result in both creative and destructive outcomes since there are some crucial differences between entrepreneurial innovations à la Schumpeter as the positive force in economic development, and financial innovations à la Minsky as the source of instabilities. The article then focuses on the weaknesses and inconsistencies of loosely regulated financial markets and suggests a few principles for rele-vant financial regulation in an endogenously unstable economy. The main contribution of the article is that financial stability must be regarded as a public good to be provided by an economy-wide regulatory framework under the supervision of a visible public hand. The study of the conditions of financial stability proves to be a matter of a specific social dilemma—opposition between private and public interests—that concerns the organisation and management of financial markets at the macroeconomic level. Such a dilemma leads to the ultimate regulatory issue of spurring the innovation dynamics of financial markets while ensuring systemic stability and sustainability through an appropriate regulatory and supervisory environment.

IT specialists engaged in the issues of evolutionary algorithms claim that there has been a transfer of knowledge from biology to computer science, i.e., certain findings in evolutionary biology have become an inspiration for the creation of algorithms whose function is analogous to that of naturally occurring evolutionary processes. If this is correct, the following question should beanswered: what is the extent of knowledge transfer from evolutionary biology to computer science dealing with evolutionary algorithms? Answering this question becomes possible after a prior review of the working mode of evolutionary algorithms.
Informatycy zajmujący się problematyką algorytmów ewolucyjnych twierdzą, że miał miejsce transfer idei z biologii do informatyki, tzn. że ustalenia biologii ewolucyjnej stały się inspiracją do powstania tych algorytmów i że działają one analogicznie do procesów ewolucyjnych zachodzących w świecie przyrody. Jeśli jest tak faktycznie, to warto odpowiedzieć na pytanie, w jakim zakresie następuje przeniesienie ustaleń z biologii ewolucyjnej do działu informatyki zajmującego się algorytmami ewolucyjnymi. Zadanie to stanie się możliwe po uprzednim zreferowaniu sposobu działania algorytmów ewolucyjnych.

Opis:
The following paper is a theoretical and empirical study. The terminological differences between bankruptcy and insolvency have been indicated and compared in the article. Most frequently considered aspects of bankruptcy appear in definitions. The first of them emphasizes the economic character of bankruptcy. Insolvency is a culmination of a lack of financial means and the loss of solvency, which does not have a fading tendency, but develops into a permanent phenomenon. In legal terms, insolvency is an institution, whose purpose is to stop the accumulation of debts and most frequently it consists on the liquidation of the debtor's estate. The main purpose of the study is a critical review of the scientific achievements of the representatives of evolutionary economics within the scope and mechanism of bankruptcy and the survival of enterprises. The analyzed case of the Beta company, which went bankrupt, indicates that the companies which are not able to undertake proper adjustments to competitive conditions of the market at the right moment are eliminated from it. The theoretical law “the survival of the fittest” finds then its reflection in practice. The following research methods were used in the article: a descriptive analysis and the trajectories of J. Argenti in terms of models. Detailed examinations of files of insolvency proceedings of the Beta company have been carried out.

Opis:
Zgodnie z teorią ewolucji i rozwoju białoruskiego systemu gospodarki powinny być skierowane na poprawę innowacyjności w poziomie mikro i makro. Obecne tendencje globalizacji gospodarek narodowych prowadzi do tego, że w ostatnich latach wzrosły penetracji produktów hightech na rynkach krajowych. Działalność innowacyjną przedsiębiorstw jest ograniczony przez wielu obiektywnych i subiektywnych problemów (globalny kryzys finansowy, niestabilność finansowa, wysokie ryzyko, brak odpowiednich badań i środków planowania, naukowe i rynku informacji itp.). Optymalna struktura wydatków na innowacje jest jednym z czynników wpływających na działalność innowacyjną podmiotów gospodarczych. Jest to jeden z wektorów wejściowych strategii innowacyjności.
In order of the theory of evolutionary and systematic the development of Belarus economy needs to be re-orientated to increasing of innovation activity in micro- and macro-levels. Modern tendencies of globalization of national economies lead to recent of intensification of the processes of penetration of high-tech products into the home markets. Innovation activity of enterprises is restrained by many objective and subjective problems (global financial crisis, unstable financial, high risk, absence of one’s own research and designing resources, scientific and market information etc.). The optimal structure of innovation expenditures is one of the factors influencing the innovative activity of businesses. She is one of the input vectors of innovation strategy.

The human-centric nature of environmental thinking is a highly successful adaptation, which has biological, historical, cultural origins. The dichotomy of anthropocentrism and ecocentrism are what ultimately determine ecological attitudes. This nationally representative study presents how students in Hungarian environmental education bachelor programs view the human’s taxonomic position in the world (hierarchies, kinship), throughout evolution (determining possible directions, distancing from other organisms), the role of human power, and our rights of intervention in the environment. It shows what kind of knowledge students arrive with from public education, how they think about handling confl icts, and what impact their acquired knowledge during university years has on their environmental attitudes. It was found that at least two-thirds of students evaluated natural environmental processes, problemsand their consequences with anthropocentric preferences – in contrast to scientifi cally accepted theses.

Scheduling doctors duties in a hospital are complicated and time-consuming tasks. The person responsible for creating a duty timetable is facing one major problem when allocating doctors to time periods: the agreement between several constraining (and often mutually excluding) requirements must be found. In this paper a solution methodology for the monthly duty assignment of doctors is presented. The typical problem is described in detail, along with specific hospital environment, from which datasets for experiments have been taken. A hybrid approach that utilizes strengths of a few artificial intelligence techniques was used to solve the problem. In particular, a population of initial solutions is generated heuristically and then improved using evolutionary algorithm. Experimental results are presented along with a discussion on the computational efficiency, operational acceptability and quality of the solutions.

The paper is devoted to the modeling, analysis and optimization encountered in the design process of two-dimensional structural components made of fiber-reinforced composite materials subjected to service loading. The problem of optimal layout of reinforcing fibers in the composite in order to obtain the assumed mechanical properties of the disk is considered. The case of creation of linear and curvilinear fibers is discussed. The adequate model, relevant optimality conditions for this type of design problem are derived and the optimization procedure based on the evolutionary algorithm is proposed. The problem considered in the paper is illustrated by some numerical examples.

This paper presents the possibility of the parametric identification of an unknown low energy explosive basing only on its ballistic curve using advanced optimisation algorithm. What was under investigation here was the approach of an explosive replication for the numerical investigation of ANSYS AUTODYN solver. The emphasis was given here for the propellants used in the automotive safety devices. The results of closed bomb testing was compared with its numerical representation. The required parameters to develop a new numerical model of an explosive was identified with the aid of evolutionary algorithm. In order to perform a parametric identification a mathematical model of considered phenomenon is required. Hence, this paper contains a mathematical model of a deflagration process which was the basis for the evolutionary algorithm. The algorithm verified a variety of parameters until the objective function is obtained. In the case of this paper the objective function was a ballistic curve of an unknown explosive which combust under deflagration regime. The results obtained with this method shows good agreement with the closed bomb test of the propellant. Furthermore, advanced optimisation tools such as an evolutionary algorithms, in oppose to most of other optimisations algorithms, enables to find a global optimum. However, the identified function here was found to be unimodal.

In this paper a brief study of coevolutionary algorithm is presented. The coevolutionary algorithm (CA) is an evolutionary algorithm (or collection of evolutionary algorithms) in which the fitness of an individual depends on the relationship between that individual and other individuals. CA can be divided into two fundamental sub-types. In cooperative algorithms, individuals are rewarded when they work well with other individuals and punished when they perform poorly. In competitive algorithms, however, individuals are rewarded at the expense of those with which they interact. The principle of operation of CA is quite similar to traditional evolutionary algorithm. The main deference lies in a fact that CA operate on multi-populations and evaluate individual based on its collaboration with individuals (collaborators) from other populations. Applying CA requires decomposition of the problem into components and assigning each component to a population. This article presents an optimization of discontinuous and multimodal functions using cooperative coevolutionry algorithm. The modified testing functions: Rosenbrocka, Styblinskiego-Tanga and Schaffer’a are decomposed and minimize using coevolutionary algorithm. Obtained results allow to evaluate the quality of the algorithm and will be used for further research on the topic.

Opis:
Biologically inspired computing that looks to nature and biology for inspiration is a revolutionary change to our thinking about solving complex computational problems. It looks into nature and biology for inspiration rather than conventional approaches. The Human Immune System with its complex structure and the capability of performing pattern recognition, self-learning, immune-memory, generation of diversity, noise tolerance, variability, distributed detection and optimisation - is one area that has been of strong interest and inspiration for the last decade. An air conditioning system is one example where immune principles can be applied. This paper describes new computational technique called Artificial Immune System that is based on immune principles and refined for solving engineering problems. The presented system solution applies AIS algorithms to monitor environmental variables in order to determine how best to reach the desired temperature, learn usage patterns and predict usage needs. The aim of this paper is to explore the AIS-based artificial intelligence approach and its impact on energy efficiency.

Opis:
A sub-type of multi-agent systems (MAS) called evolutionary ones (EMAS), special in its features and field of application, needs a dedicated architecture that would be more adequate and easier in design and implementation. The proposed architecture uses the notion of a profile which models strategies and goals of an agent with respect to an aspect of its operation. To make a decision, an agent is equipped with an algorithm that coordinates premises determined in its profiles. The paper presents main ideas of the architecture illustrated with an actual realisation of an EMAS solving the multi-objective optimisation problem.

Opis:
The following paper presents a new method for choosing a set of master degrees of freedom for the process of dynamic condensation in order to reduce a finite element model. The general rule is that the more degrees of freedom are eliminated, the more accurate the reduced model is. However, eliminating different subsets (of equal sizes) of degrees of freedom may influence the accuracy differently. Therefore, choosing an optimal subset is crucial. The presented method is based on multicriterial evolutionary optimization which makes it the first nondeterministic approach based on computational optimization technique for this application.

Opis:
In this work, evolutionary algorithms together with the Metropolis-Hastings sampling technique have been used for parameter identification of the Wohler curve of duraluminum alloy 2024-T3. An evolutionary algorithm is a subset of evolutionary computation, a generic population-based metaheuristic optimization algorithm. The Metropolis-Hasting algorithm is one of the most widespread Markov chain Monte Carlo methods for posterior distribution estimation. In this contribution, both algorithms have been presented to estimate the probability density functions using Wohler parameters as a case study. Results were shown in terms of distribution shape and parameter correlations and the differences, arising from applied algorithms, have been compared. The information about parameter distributions of Wohler equation is useful to prepare risk analyses based on statistical safe life approach. The safe life approach can be met, for instance, in assessing the reliability of an aircraft.

The paper presents a newly designed improvement to the method of solving multi-ship encounter situations. In general, the method combines some of the assumptions of game theory with evolutionary programming and aims to find optimal set of cooperating trajectories of all ships involved in an encounter situation. The improvement presented here is a new way of modelling some of the COLREGS rules. Due to this change, the method is now able to find solutions, which are more compliant with COLREGS, more intuitive and consequently – safer from the navigator’s point of view.

Opis:
Differential Evolution (DE) is a simple, yet highly competitive real parameter optimizer in the family of evolutionary algorithms. A significant contribution of its robust performance is attributed to its control parameters, and mutation strategy employed, proper settings of which, generally lead to good solutions. Finding the best parameters for a given problem through the trial and error method is time consuming, and sometimes impractical. This calls for the development of adaptive parameter control mechanisms. In this work, we investigate the impact and efficacy of adapting mutation strategies with or without adapting the control parameters, and report the plausibility of this scheme. Backed with empirical evidence from this and previous works, we first build a case for strategy adaptation in the presence as well as in the absence of parameter adaptation. Afterwards, we propose a new mutation strategy, and an adaptive variant SA-SHADE which is based on a recently proposed self-adaptive memory based variant of Differential evolution, SHADE. We report the performance of SA-SHADE on 28 benchmark functions of varying complexity, and compare it with the classic DE algorithm (DE/Rand/1/bin), and other state-of-the-art adaptive DE variants including CoDE, EPSDE, JADE, and SHADE itself. Our results show that adaptation of mutation strategy improves the performance of DE in both presence, and absence of control parameter adaptation, and should thus be employed frequently.

The paper presents an experiment involving the use of an evolutionary algorithm to reconstruct the sine wave signal with white noise added based on limited number of its random samples. The experimental results show that such an algorithm is able to identify the test signal with a high accuracy even when the noise level is high (SNR = 0 dB). The behavior of the algorithm used is examined, the convergence and accuracy of results are tested, depending on the parameters of the reconstructed signal. The directions for further research are outlined.

The main goal of the paper is to outline a new Artificial Neural Network (ANN) encoding method called Assembler Encoding (AE). In AE, ANN is encoded in the form of a program (Assembler Encoding Program - AEP) of linear organization and of a structure similar to the structure of a simple assembler program. The task of AEP is to create the so-called Network Definition Matrix (NDM) including the whole information necessary to produce ANN. To create AEPs, and in consequence ANNs, genetic algorithms are used.
Głównym celem artykułu jest przedstawienie Kodowania Asemblerowego czyli nowej metody kodowania sztucznych sieci neuronowych. W Kodowaniu Asemblerowym sieć neuronowa jest zakodowana w postaci programu (AEP - Assembler Encoding Program) o liniowej organizacji i o strukturze podobnej do struktury prostego programu asemblerowego. Zadaniem AEP jest stworzenie tzw. Macierzy Definicji Sieci (NDM - Network Definition Matrix) zawierającej całą informację potrzebną do stworzenia sieci. Tworzenie AEP i w konsekwencji sieci neuronowych odbywa się z wykorzystaniem technik ewolucyjnych.

Opis:
The purpose of this paper was to investigate in practice the possibility of using evolutionary algorithms to solve the traveling salesman problem on a real example. The goal was achieved by developing an original implementation of the evolutionary algorithm in Python, and by preparing an example of the traveling salesman problem in the form of a directed graph representing Polish voivodship cities. As part of the work an application in Python was written. It provides a user interface which allows to set selected parameters of the evolutionary algorithm and solve the prepared problem. The results are presented in both text and graphical form. The correctness of the evolutionary algorithm's operation and the implementation was confirmed by performed tests. A large number of tested solutions (2500) and the analysis of the obtained results allowed for a conclusion that an optimal (relatively suboptimal) solution was found.

Opis:
The article proposes implementing a modified version of genetic algorithm in a neural network, what in literature is known as “evolutionary algorithm” or “evolutionary programming”. An Evolutionary Algorithm is a probabilistic algorithm that works in a set of weight variability of neurons and seeks the optimal value solution within a population of individuals, avoiding the local maximum. For chromosomes the real value variables and matrix structure are proposed to a single-layer neural network. Particular emphasis is put on mutation and crossover algorithms. What is also important in both genetic and evolutionary algorithms is the selection process. In the calculation example, the implementation of theoretical considerations to a classification task is demonstrated.

The analysis was carried out taking into account the structural and functional conditions of the regions and cities. In this article the author discusses the conditions and factors facilitating the strengthening of the adaptability of the regional economy and urban, with regard to the principles of evolutionary economic geography. The aim of the paper is to present the possibilities of application of the concept of regional and urban resilience to recent analyzes of regional development, with particular emphasis on evolutionary approach. The author applied the descriptive method and the comparative method. The analyzes are based on literature studies. Individualized study of social, economic and spatial structures of various spatial units, taking into account their resilience, can provide valuable information on the processes of adaptation of regions and cities and thus favorable conditions for their resistance, recovery, re-orientation and renewal.

The present paper aims at exploring some ways in which an evolutionary-developmental-psychological (EDP) perspective can explain the adaptive nature of self-esteem. This paper attempts to address some important issues that are the focus of evolutionary psychology, including, possible evolutionary functions of self-esteem, by focusing on two theories namely, the Terror Management Theory (TMT) and the Sociometer Theory. Additionally, this review also attempts to identify some of the links between self-esteem and social relationships using an evolutionary-developmental-psychological (EDP) framework.

The coupling of modern, alternative optimization methods such as evolutionary algorithms with the effective tool for analysis of mechanical structures - BEM, gives a new optimization method, which allows one to perform the generalized shape optimization (simultaneous shape and topology optimization) for elastic mechanical structures. This new evolutionary method is free from typical limitations connected with classical optimization methods. In the paper, results of researches on the application of evolutionary methods in the domain of mechanics are presented. Numerical examples for some optimization problems are presented, too.

Metoda ta jest pozbawiona wad związanych z typowymi klasycznymi metodami optymalizacji (ciągłość funkcji celu, wyznaczanie gradientu funkcji itp.), co znacznie rozszerza możliwości jej zastosowań. W artykule przedstawiono proponowaną metodę optymalizacji wraz z przykładami optymalizacji wybranych układów mechanicznych.

Aim. This paper elucidates how the emergent impact agenda is slowly but surely changing the normative framework of modern Western science. Method. The paper investigates conceptually the implications of the impact agenda for the research process. We outline a chronology around the evaluation regime of research impact and identify the causal mechanisms that change the disciplinary structure of the research ecosystem. We draw upon a sociological model of scientific knowledge production to contrast and discuss how impact facts mimic the process of scientific knowledge production but are geared towards a different end. Results. Our findings indicate that an explicit emphasis on societal contribution not only propositions a different purpose of research, but also changes the logic of research along its entire construction. The impact logic mimics the creation of scientific facts; nevertheless, as it is geared towards a different end, it hermetically seals itself from criticism as any form of scrutiny would otherwise undermine its own legitimacy. Conclusion. We conclude that only explicit acknowledgement of the adverse potential of the impact agenda can maintain science’s benefit to society. We argue that an emphasis on the advancement of knowledge, as opposed to impact, can maintain innovation and preempt social tension. The contribution of this paper lies in identifying the societal influence of the scientific ideal of truth, and articulating the unintended consequences of the impact agenda as the emerging impact or starve paradigm.

Opis:
Organizations across the globe gather more and more data, encouraged by easy-to-use and cheap cloud storage services. Large datasets require new approaches to analysis and processing, which include methods based on machine learning. In particular, symbolic regression can provide many useful insights. Unfortunately, due to high resource requirements, use of this method for large-scale dataset analysis might be unfeasible. In this paper, we analyze a bottleneck in the open-source implementation of this method we call hubert. We identify that the evaluation of individuals is the most costly operation. As a solution to this problem, we propose a new evaluation service based on the Apache Spark framework, which attempts to speed up computations by executing them in a distributed manner on a cluster of machines. We analyze the performance of the service by comparing the evaluation execution time of a number of samples with the use of both implementations. Finally, we draw conclusions and outline plans for further research.

The aim of the study was to use evolutionary operations (EVOP) to evaluate changes in the behaviour of dairy cows depending on the strategy according to which they were grouped after calving. The experiment was carried out on a Danish farm keeping about 200 Holstein cows. The farm had two separate areas for lactating cows: a small area with 54 waterbeds and a larger area with 133 beds with mattresses. During the experiment both areas were filled with cows. Cows after calving were introduced to either the small area (group) or the large area (group). After 14 days, the cows from the small group were transferred to the large group. The impact of different cow grouping strategies on their lying time, considered a welfare indicator, was examined. During the 210-day experiment, 195,703 observations were collected. The behavioural data were analysed using a linear mixed-effect regression model fitted by the maximum likelihood method. Days in milk, parity number, and lying time of herd mates were found to significantly affect the lying time of individual cows, while the strategy of cow grouping after calving had no effect on lying time.

Opis:
Cases where the derivative of a boundary value problem does not exist or is constantly changing, traditional derivative can easily get stuck in the local optima or does not factually represent a constantly changing solution. Hence the need for evolutionary algorithms becomes evident. However, evolutionary algorithms are compute-intensive since they scan the entire solution space for an optimal solution. Larger populations and smaller step sizes allow for improved quality solution but results in an increase in the complexity of the optimization process. In this research a population-distributed implementation for differential evolution algorithm is presented for solving systems of 2nd-order, 2-point boundary value problems (BVPs). In this technique, the system is formulated as an optimization problem by the direct minimization of the overall individual residual error subject to the given constraint boundary conditions and is then solved using differential evolution in the sense that each of the derivatives is replaced by an appropriate difference quotient approximation. Four benchmark BVPs are solved using the proposed parallel framework for differential evolution to observe the speedup in the execution time. Meanwhile, the statistical analysis is provided to discover the effect of parametric changes such as an increase in population individuals and nodes representing features on the quality and behavior of the solutions found by differential evolution. The numerical results demonstrate that the algorithm is quite accurate and efficient for solving 2nd-order, 2-point BVPs.

A studied phenomenon is a radiation induced bystander effect, in which three different strategies (phenotypes) of cells take part. The proposed payoff table of fitness, related to environment adaptation and genetic cell behavior, contains costs/profits of bystander effect, choice of apoptotic pathway, producing growth factors and resistance against bystander effect. We consider a game theory model including spatial cells allocation (the game is played on lattice). We discuss also different polymorphic equilibrium points dependent on model parameters, types of spatial games and players distribution.

The period between the two World Wars was very fruitful for Polish philosophy. The best known intellectual formation of that time was the Lvov–Warsaw School of Logic. At the time, when members of that school philosophized in the context of logic and mathematics, there was a group of thinkers in Cracow, who attempted at creating a philosophy of nature. Unfortunately, because of the outbreak of the Second World War, they have never produced any philosophical school. One of the first of Cracow philosophers of nature was the biologist, Tadeusz Garbowski. He died in 1939 in Sachsenhausen concentration camp, leaving several philosophical papers which focus mostly on the theory of evolution. In the present paper, the author critically reviews his analyses. A lot of his ideas, e.g., the one called by the author the 'evolutionary epistemology', can be found in works of later thinkers, for instance in the works of Konrad Lorenz. Although it is doubtful that they actually knew Garbowski's papers, it still seems to be worthwhile to notice this historical fact.

Opis:
Ekonomia ewolucyjna zaliczana jest do ekonomii heterodoksyjnej, której obszar zainteresowań koncentruje się na zagadnieniach związanych ze zmianami zachodzącymi w systemie ekonomicznym oraz ich przesłankami i konsekwencjami. Współczesna ekonomia ewolucyjna, akceptując, że rzeczywistość jest dynamiczna, skupia się na badaniu tego, w jaki sposób ewoluuje gospodarka, szukając źródeł i mechanizmów dynamiki. W tych stwierdzeniach można zawrzeć podstawowy wyróżnik ontologiczny i metodologiczny ekonomii ewolucyjnej. Celem artykułu jest zdefiniowanie ekonomii ewolucyjnej, a także przedstawienie jej historycznych korzeni, współczesnych poglądów oraz perspektywy rozwoju. Zagadnienia przedstawione w opracowaniu nie opisują całego jej spektrum, a jedynie wybrane elementy. Artykuł ma charakter teoretyczny i składa się z pięciu części. W pierwszej części tekstu skupiono się na wyjaśnieniu pojęcia i kluczowych założeń ewolucjonizmu w naukach społecznych. W dalszej części artykułu omówiono istotę ekonomii ewolucyjnej, a także przedstawiono jej korzenie. Z uwagi na wymogi objętościowe czasopisma skoncentrowano się wyłącznie na prezentacji poglądów najważniejszych przedstawicieli tej dyscypliny naukowej. W końcowej części artykułu, w sposób syntetyczny, przybliżono najważniejsze słabości ekonomii ewolucyjnej oraz perspektywy jej rozwoju.
Evolutionary economics is considered to be part of heterodox economics, which focuses on developments in the economic system, their reasons and consequences. Accepting that the reality is dynamic, contemporary evolutionary economics examines the ways in which the economy evolves, seeking origins and mechanisms of its dynamics. These statements reflect the fundamental ontological and methodological characteristics of evolutionary economics. This article aims at defining evolutionary economics and presenting its historical roots, current views and prospects for development. The issues put forward do not describe its entire range, but only selected elements. This paper is theoretical and consists of five parts. The first part concentrates on explaining the concept and key assumptions of evolutionism in social sciences. Further, the essence of evolutionary economics and its origins are discussed. Owing to the length requirements, the focus is exclusively on presenting the views of the most prominent representatives of this scientific discipline. The final part synthesises fundamental weaknesses of evolutionary economics and prospects for its development.

Opis:
Previous studies in multi-agent systems have observed that varying the type of information that agents communicate, such as goals and beliefs, has a significant impact on the performance of the system with respect to different, usually conflicting, performance metrics, such as speed of solution, communication efficiency, and travel distance/cost. Therefore, when designing a communication strategy for a multi-agent system, it is unlikely that one strategy can perform well with respect to all of performance metrics. Yet, it is not clear in advance, which strategy will be the best with respect to each metric. With multi-agent systems being a common paradigm for building distributed systems in different domains, performance goals can vary from one application to the other according to the domain’s specifications and requirements. To address this issue, this work proposes a genetic algorithm-based approach for learning a goal- oriented communication strategy. The approach enables learning an effective communication strategy with respect to flexible, user-defined measurable performance goals. The learned strategy will determine what, when, and to whom information should be communicated during the course of task execution in order to improve the performance of the system with respect to the stated goal. Our preliminary evaluation shows that the proposed approach has promising results and the learned strategies have significant usefulness in improving the performance of the system with respect to the goals.

Opis:
The paper presents a novel heuristic procedure (further called the AH Method) to investigate function shape in the direct vicinity of the found optimum solution. The survey is conducted using only the space sampling collected during the optimization process with an evolutionary algorithm. For this purpose the finite model of point-set is considered. The statistical analysis of the sampling quality based upon the coverage of the points in question over the entire attraction region is exploited. The tolerance boundaries of the parameters are determined for the user-specified increase of the objective function value above the found minimum. The presented test-case data prove that the proposed approach is comparable to other optimum neighborhood examination algorithms. Also, the AH Method requires noticeably shorter computational time than its counterparts. This is achieved by a repeated, second use of points from optimization without additional objective function calls, as well as significant repository size reduction during preprocessing.

Opis:
The paper presents an analogue circuit testing method that engages the analysis of the time response to a nonperiodic stimulus specialized for the verification of selected specifications. The decision about the current circuit diagnostic state depends on an amplitude spectrum decomposition of the time response measured during the test. A shape of the test excitation spectrum is optimized with the use of a differential evolution algorithm and it allows for achieving maximum fault coverage and the optimal conditions for fault isolation. Genotypes of the evolutionary system encode the amplitude spectrum of candidates for testing stimuli by means of rectangle frequency windows with amplitudes determined evolutionarily.

Opis:
The Multicriteria Evolutionary Weather Routing Algorithm (MEWRA) has already been introduced by the author on earlier TransNav 2009 and 2011 conferences with a focus on theoretical application to a hybrid‐propulsion or motor‐driven ship. This paper addresses the topic of possible practical weather routing applications of MEWRA. In the paper some practical advantages of utilizing Pareto front as a result of multicriteria optimization in case of route finding are described. The paper describes the notion of Paretooptimality of routes along with a simplified, easy to follow, example. It also discusses a choice of the most suitable ranking method for MEWRA (a comparison between Fuzzy TOPSIS and Zero Unitarization Method is presented). In addition to that the paper briefly outlines a commercial application of MEWRA.
