Differential Evolution Without the Scale Factor F
Sanyang Liu · Dianzi xuebao · 2009
A fit setting of the scale factor F can usually improve greatly the performance of differential evolution,however,how to set is nuisance.Two differential evolutions without scale factor F are presented in the paper.The algorithms look upon each individuals as a charged particle and utilize the attraction-repulsion mechanism of the particles to decide on the step length of the motion of the individual in the direction of the difference for the purpose of avoiding the setting of the scale factor F.The comparisons of numerical experiments among the proposed algorithms,two PSO algorithms and four other algorithms with the different setting strategies are done,which show that the performance of the proposed algorithms outperform other compared algorithms.
