The paper presents a comparative study of five migration policies for parallel genetic algorithm (PGA) solving the traveling salesman problem (TSP). The investigated migration policies utilize one way ("slow") and two way ("fast") circular periodic chromosomes migration and global ("immediate") periodic chromosomes migration. For each migration policy best… (More)
This article presents an exploration of Differential Evolution (DE) algorithm with enhanced adaptability. The main purpose of this study is to identify how this search method can cope with changes of the number of variables of a hard design test, unaided. The results clearly show that this method successfully solves the explored functions.
