Opis:
The main purpose of this paper is to provide an overview of the ideas behind Tabu Search - one of the most popular metaheuristic appoaches. For the sake of concreteness a simple example of the traveling salesman problem will be used in the discussion to illustrate the process of designing a Tabu Search algorithm. In addition, some extensions will be presented. Finally, applications will also be provided as well as references to more specialized publications.

Opis:
Most of multiple criteria scheduling problems are NP-hard, so that exact procedures can only solve small problems and with two criteria. The complexity and the diversity of multiple criteria scheduling problems resulted in many alternative approaches to solve them. Exact and approximate procedures proposed in the literature are mainly dedicated to the problem to be solved and their performance depends on the problem data, on the criteria optimized, and are generally difficult to implement. We propose in this paper a Tabu Search approach to multiple criteria scheduling problems. The proposed procedure is a general flexible method, able to solve hard multiple criteria scheduling problems, easy to implement, and providing a set of potential efficient schedules. The criteria are any combination chosen from (C[sub max],T[sub max], L, N[sub T] and F).

Opis:
The problem of designing a near optimal configuration of a system of one-way and two-way routes is investigated. Each arc of the network can be designed as either a two-way arc or a one-way arc in one of the two directions. The traffic speed on a one-way arc is faster than the speed on a two-way arc by a given factor. The problem is to design a network which minimizes total travel time between all pairs of nodes by the proper selection of one-way and two-way arcs. Efficient implementations of the metaheuristic tabu search are designed for solving this network design problem. These approaches are tested on a set of network problems with encouraging results.

Opis:
In this paper we develop a general convergence theory for nonmonotone line searches in optimization algorithms. The advantage of this theory is that it is applicable to various step size rules that have been published in the past decades. This gives more insight into the structure of these step size rules and points to several relaxations of the hypotheses. Furthermore, it can be used in the framework of discretized infinite-dimensional optimization problems like optimal control problems and ties the discretized problems to the original problem formulation.

Opis:
In this paper, we present the soft approaches and techniques developed within Matrioshka, a prototypal meta-search system aimed at providing personalized exploratory facilities, addressing the well known Ranked-List Problem. Matrioshka implements a novel interaction framework that provides tools for clustering documents retrieved by search engines, tools for exploring the content of clusters through the analysis of some cluster properties, tools for generating disambiguated queries from the clusters, and tools for combining the clusters to highlight their shared contents. All these tools are defined based on soft operations, in order to deal with intrinsic semantic ambiguity, imprecision and uncertainty of complex web searches. In this way, the user is supported in the deployment of complex web search exploratory activities.

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:
This paper examines integration of a sophisticated, pivot-based tabu search into branch and bound for 0-1 MIPS and global diversification tests using chunking. Issues related to behavior of a tabu search within a branch and bound algorithm are analyzed using computational experiments. Results are presented showing that the inclusion of the local search sometimes results in fewer and nodes and lower CPU times even when used in a callback mode. The main benefit in incorporating a pivot based heuristic is that an integer feasible solution can be found earlier in the branching process. Computational experiments are presented showing that for some instances the overall search time is improved, while for some others the tabu search can find good solutions quickly.

Opis:
This paper examines the use of hashing in the multiobjective tabu search, TAMOCO. The hasliing method was suggested by Woodruff and Zemel (1993) as a method of avoiding return to the already examined solutions in the standard single-objective tabu search. While the traditional tabu list is capable of insuring this, it can normally only be used for cycles of a moderate length. The hashing method, however, can efficiently avoid cycles over a much larger number of iterations and must be considered a natural component in the tabu search tool-box. We report from two experiments on practical models where the hashing component has been included into the TAMOCO-procedure ; with two different outcomes.

Opis:
In this paper we build and solve a heterogeneous-agent dynamic stochastic general equilibrium (DSGE) model with incomplete markets in the spirit of Krussel and Smith (1998). We expand this model to account for search and matching labour market frictions, using the classic Mortensen and Pissarides (1994) framework. The model, therefore, combines two important strands of economic modelling and presents a numerical challenge in terms of solving the model due to the inclusion of additional dimensions in the optimization problem. Despite the addition of additional state variables and higher dimensionality, we show that we are able to efficiently solve it numerically using value function iteration and we document basic properties of the model.

Opis:
This paper presents the multiobjective tabu search method, TAMOCO. Being an adaptation of the well-known tabu search, it can be used to generate approximations to the non-dominated solutions of multiobjective combinatorial optimization problems. TAMOCO works with a set of current solutions which, through manipulation of weights, are optimized towards the non-dominated frontier while at the same time seek to disperse over the frontier. The general procedure and some extensions to it are presented, as well as suggestions of usage in interactive procedures. A computational experiment is also presented.

Opis:
The issue of ORPD (Optimal Reactive Power Dispatch) for enhancing security and economy of a power system has been given substantial consideration in recent days. The major inspiration behind deploying an ORPD system for enhancing power system efficiency is to reallocate the RP (reactive power) in such a manner that power loss be minimized, and voltage profiles get enhanced. Hence, this paper concerns the major objectives, namely, reduction of power loss and voltage deviation that are related to solving ORPD problem under unbalanced condition. To attain these objectives, an amalgamation of two algorithms, called CS (Cuckoo Search) and GWSO (Glow Worm Swarm), is adopted for optimizing, and hence the proposed model is referred to as CP-GWSO. This algorithm functions with the control parameters, namely load reactance, voltage and transformer tap settings that are tuned to attain the optimum outcome. The entire empirical part of the investigations is performed on two IEEE standard test bus systems, the IEEE 14 and the IEEE 39 bus systems. Finally, the proposed scheme is compared to the conventional methods, and its efficiency is confirmed.

Intelligent control techniques for power generation facilities are presented. A methodology for estimating the dynamics of participation of the power grid generating facilities in the overall primary frequency regulation in contingency situations is developed based on frequency and generating capacity time series. Process identification algorithms, based on virtual model design using process data archives and knowledge bases, are discussed. Associative search methods are used for identification algorithm development.

Opis:
This paper addresses the problem of fixed channel assignment in cellular communication systems with nonuniform traffic distribution. The objective of the channel assignment is to minimise the average blocking probability. Methods for finding a good allocation can be based on first building a number of sets of cochannel cells or allocation patterns and then assigning them to channels. This usually implies that only a subset of the feasible region is attainable. The approach suggested in this paper uses the concept of packed pattern, since all patterns in an optimal solution will be of that kind. With a constructive method, the entire set of packed patterns is built and used in the optimisation process. The complexity (large-scale and nonlinearity) of the resulting problem suggested the use of general search procedures (local search, tabu search, simulated annealing, etc.), which have the further advantage of flexibility when dealing with extensions to the problem. A neighbouring structure was used, that facilitated the calculations while still allowing for the search in the entire solution space. A summary of extensive numerical experiments is presented. The outcome is an improvement over previous results.
