Differential Evolution, Evolution Strategy, cooperative model, competition, experiments, global optimization

A cooperative model of well-known evolutionaryalgorithms is proposed and tested on CEC 2019 benchmark suite. The four adaptive algorithms are chosen for this model, namely Covariance Matrix Adaptation Evolutionary Strategy (CMA-ES) and three variants of adaptive Differential Evolution. Although the three algorithms use constant population size, the proposed model employs an efficient linear population size reduction mechanism. The provided results show that theCooperative Model of Evolutionary Algorithms (CMEAL) is able to solve seven out of ten optimization problems.
