Abstract
Differential evolution DE algorithm is a population based stochastic search technique widely applied in scientific and engineering fields for global optimization over real parameter space The performance of DE algorithm highly depends on the selection of values of the associated control parameters Therefore finding suitable values of control parameters is a challenging task and researchers have already proposed several adaptive and selfadaptive variants of DE In the paper control parameters are adapted by levy distribution named as Levy distributed DE LdDE which efficiently handles exploration and exploitation dilemma in the search space In order to assure a fair comparison with existing parameter controlled DE algorithms we apply the proposed method on number of wellknown unimodal basic and expanded multimodal and hybrid composite benchmark optimization functions having different dimensions The empirical study shows that the proposed LdDE algorithm exhibits an overall better performance in terms of accuracy and convergence speed compared to five prominent adaptive DE algorithms
