Keywords:
Large-Scale, Optimization, Evolutionary Algorithm, Multiobjective Optimization, Manyobjective Optimization, Differential Evolution, Pareto FrontAbstract
Large scale optimization problems map situations where the decision space is very large. Such
problems are frequently encountered in engineering. Large scale problems are called large scale because
of the size of the decision space, but this does not mean that these problems are expe4nsive. Nevertheless,
due to the large size, traditional selection procedures do not work efficiently. Although these problems
can be solved with traditional optimization algorithms, some mechanisms have been proposed to obtain
better solutions for the same computational resource. The aim of these mechanisms is to simplify the
problem and solve it faster and more accurately. In this research, these mechanisms will be compared
with each other. For this comparison, two algorithms from each category will be selected and applied to
nine benchmark problems. The empirical results obtained and the algorithms and the categories to which
they belong will be compared.
