В последние десятилетия метаэвристические методы оптимизации стали популярными для решения сложных задач, требующих поиска глобальных экстремумов. Алгоритмы, такие как генетический алгоритм (GA), оптимизация колоний муравьев (ACO), оптимизация роя частиц (PSO), а также более современные подходы, как алгоритм кошачьей стаи (CSO) и оптимизация стаи серых волков (GWO), демонстрируют высокую эффективность, но их применение зачастую ограничивается условиями непрерывности и дифференцируемости целевых функций. Это представляет собой вызов при решении задач с дискретными данными, где такие требования не соблюдаются. В данном контексте особую актуальность приобретает поиск методов, позволяющих адаптировать метаэвристические алгоритмы для работы с дискретными функциями.</p><p>Цель исследования направлена на проверку гипотезы о возможности использования нейронной сети, обученной на ограниченном наборе дискретных данных, в качестве аппроксимации функции, достаточной для корректного выполнения алгоритма GWO при поиске глобального минимума. </p></sec><sec><title>Методы</title><p>Методы. Исследование основано на анализе существующих подходов и экспериментальной проверке гипотезы на двух тестовых функциях: линейной функции и функции Бута, которые широко применяются в качестве стандартов для оценки производительности алгоритмов оптимизации. Для получения результатов проведены численные эксперименты с использованием нейронных сетей в качестве аппроксимирующей модели.</p></sec><sec><title>Решение</title><p>Решение. В ходе экспериментов проведен анализ применимости нейронных сетей для аппроксимации дискретных функций, показавший успешность данного подхода. Было установлено, что нейронные сети могут с высокой точностью аппроксимировать дискретные функции, создавая условия для успешного поиска глобального минимума с использованием алгоритма GWO.</p></sec><sec><title>Новизна</title><p>Новизна. Впервые предложена и проверена гипотеза о применении нейронных сетей для аппроксимации целевых функций в задачах метаэвристической оптимизации на дискретных данных. Это направление ранее не получило должного освещения в научной литературе, что придает ценность полученным результатам и подтверждает эффективность предложенного подхода.</p></sec><sec><title>Значимость</title><p>Значимость. Результаты исследования открывают новые перспективы для применения алгоритмов, таких как GWO, в задачах оптимизации, основанных на дискретных данных, расширяя возможности метаэвристических методов и способствуя их внедрению в более широкий класс прикладных задач, включая задачи, где применение других методов ограничено.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. In recent decades, metaheuristic optimization methods have become popular for solving complex problems that require searching for global extrema. Algorithms such as genetic algorithm (GA), ant colony optimization (ACO), particle swarm optimization (PSO), as well as more modern approaches such as cat pack optimization (CSO) and gray wolf pack optimization (GWO) demonstrate high efficiency, but their application is often limited by the conditions of continuity and differentiability of the objective functions. This is a challenge when solving problems with discrete data, where such requirements are not met. In this context, the search for methods that allow adapting metaheuristic algorithms to work with discrete functions is of particular relevance.</p></sec><sec><title>Aim</title><p>Aim. The study is aimed at testing the hypothesis about the possibility of using a neural network trained on a limited set of discrete data as an approximation of a function sufficient for the correct execution of the GWO algorithm when searching for a global minimum. The implementation of this hypothesis can significantly expand the scope of GWO, making it available for a wider range of problems where functions are defined on discrete sets.</p></sec><sec><title>Methods</title><p>Methods. The study is based on the analysis of existing approaches and experimental verification of the hypothesis on two test functions: a linear function and a Booth function, which are widely used as standards for evaluating the performance of optimization algorithms. Numerical experiments were conducted using neural networks as an approximating model to obtain the results. </p></sec><sec><title>Solution</title><p>Solution. During the experiments, an analysis of the applicability of neural networks for approximating discrete functions was carried out, which showed the success of this approach. It was found that neural networks can approximate discrete functions with high accuracy, creating conditions for a successful search for a global minimum using the GWO algorithm.</p></sec><sec><title>Novelty</title><p>Novelty. For the first time, a hypothesis was proposed and tested on the use of neural networks for approximating objective functions in metaheuristic optimization problems on discrete data. This direction has not previously received due coverage in the scientific literature, which adds significance to the obtained results and confirms the effectiveness of the proposed approach.</p></sec><sec><title>Practical significance</title><p>Practical significance. The results of the study open up new prospects for the application of algorithms such as GWO in optimization problems based on discrete data, expanding the capabilities of metaheuristic methods and facilitating their implementation in a wider class of applied problems, including problems where the use of other methods is limited.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>оптимизация</kwd><kwd>GWO</kwd><kwd>нейронные сети</kwd><kwd>метаэвристика</kwd><kwd>поиск глобального минимума</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optimization</kwd><kwd>GWO</kwd><kwd>neural networks</kwd><kwd>metaheuristics</kwd><kwd>search for a global minimum</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bonabeau E., Dorigo M., Theraulaz G.
