Uzyskano znaczącą poprawę modelu neuralnego wspomaganego algorytmem ewolucyjnym inspirowanym kwantowo w stosunku do modelu neuralnego wspomaganego algorytmem ewolucyjnym bez inspiracji kwantowej.
    The paper contains selected research results on the nature and implementation of the Evolutionary Algorithm inspired by quantum computation to improve the parameters of the neural model determining prices at the Polish Power Exchange. To learn the Artificial Neural Network system model, the figures quoted on the Commodity Electricity Market of the Day-Ahead Market were used in the period from January 1, 2018 to June 30, 2018. Particular attention was paid to the systemic creation of the Initial Population and the systemic creation of the function of solidification (function adaptation), and on this basis, the quantization, dequantization and quantum computation methods carried out using the quantum concept of a mixed number. Significant improvement of the neural model supported by quantum-inspired evolutionary algorithm in relation to the model without quantum inspiration was obtained.

    Opis:
    The article presents selected results of research on the modeling of humanoid robots, including the results of neural modeling of human gait and its implementation in the environment MATLAB and Simulink with the use of Deep Learning Toolbox. The subject of the research was placed within the scope of the available literature on the subject. Then, appropriate research experiments on human movement along a given trajectory were developed. First, the method of measuring the parameters present in the experiment was established, i.e. input quantities (displacement of the left heel, displacement of the right heel) and output quantities (displacement of the measurement point of the human body in space). Then, research experiments were carried out, as a result of which numerical data were measured in order to use them for teaching and testing the Artificial Neural Network. The Perceptron Artificial Neural Network architecture was used to build a model of a neural human walk along a given trajectory. The obtained results were discussed and interpreted, drawing a number of important conclusions.

Dane wejściowe, wagi i biasy poddano kwantyzacji. Kwantowe obliczenia quasi-równoległe przeprowadzono na bazie 100 wygenerowanych kwantowych liczb mieszanych za pomocą metody kwantyzacji na bazie stanów czystych |0> i |1>, a uzyskane w wyniku obliczeń kwantowe liczby mieszane poddano dekwantyzacji za pomocą Sztucznej Sieci Neuronowej (SSN). Model symulacyjny składający się ze wspomaganej ewolucyjnie oraz kwantowo inspirowanej Sztucznej Sieci Neuronowej, oprócz badań symulacyjnych, umożliwia przeprowadzanie badań komparatystycznych uzyskiwanych sygnałów z danymi rzeczywistymi oraz z danymi wyjściowymi z perceptronowej Sztucznej Sieci Neuronowej. Wyniki badań wskazują na wysoką dokładność przeprowadzanego eksperymentu.
    An evolutionary-assisted and quantum-inspired Artificial Neural Network was created, which was implemented in Simulink on the Day-Ahead Market of the Polish Power Exchange. Input data, weights and bias were quantized. Quantum quasi-parallel calculations were carried out on the basis of 100 generated quantum mixed numbers using the quantization method based on pure states |0> and |1>, and the resulting quantum mixed numbers were dequantized using another Artificial Neural Network. The implemented simulation model consists of evolutionarily assisted and quantum-inspired Artificial Neural Network, which in addition to simulation studies allows conducting comparative studies of obtained signals with real data and with output data from the perceptron Artificial Neural Network. The test results indicate the high accuracy of the experiment.

    This article, which is a continuation of the article under the same main title and subtitle: part 1 Design and its implementation, includes the obtained results of research experiments with the use of a designed and implemented racing game. It uses a neural model of the vehicle motion control system on the racetrack in the form of a Perceptron Artificial Neural Network (ANN). In designing the movement of vehicles on the racetrack, the following were used, inter alia, Godot Engine and MATLAB and Simulink programming environment. The numerical data (14 input quantities and two output quantities) for ANN training were prepared with the use of semi-automatic measurement of the race track control points. This article shows, among others, the results of 10 selected research experiments, testing and simulation, confirming the correct functioning of both the computer game and the model of the neural control system. As a result of simulation tests, it turned out that the longest lap of the track in the conducted experiments lasted 4 minutes and 55 seconds, and the shortest - 10.47 seconds. In five minutes, the highest number of laps was 34, while the lowest numbers of laps were 1 and 5. In the course of the experiments it was noticed that under the same conditions the ANN learning outcomes are sometimes different.

    The paper presents selected elements of a modelling methodology involving quantization, quantum calculations and dequantization on the example of the neural model of the Day-Ahead Market of the Polish Electricity Exchange. Based on the fundamental assumptions of quantum computing, a new method has been proposed here of converting the real numbers in decimal notation into quantum mixed numbers using the probability modules of quantum mixed number and the principle of superposition, along with a new method of quantum calculations using linear algebra and vectormatrix calculus, and the Artificial Neural Network was taught accordingly. Dequantization of quantum mixed numbers to real numbers in decimal notation using the new method of dequantization has been proposed as well. The operation of the methods introduced was shown on numerical examples.

    An analysis of the web application supporting the management of the gym was carried out, which was designed in terms of the theory of control and systems. The obtained results of measurements of input and output quantities of selected subsystems were used to carry out the identification, as a result of which models of web application subsystems were obtained. On the basis of the obtained subsystem models, appropriate models were then designed in Simulink for the purposes of simulation and comparative studies of the behavior of subsystem models in relation to real systems that are web applications, including an appropriate analysis of the web application system model was carried out under the name of the gym on its selected subsystems, including in particular the subsystem called Generating a diet. In addition, testing and simulation studies were carried out to check the correct functioning of the web application management system model and the introduction of appropriate changes to the model was proposed, and the obtained research results were discussed, indicating the high accuracy of the obtained web application models.
