Abstract

In this paper, an improved hybrid approach is developed to find global minima of the problem. The proposed approach consists of population based approaches PSO and DE. In the proposed approach, the global best obtained from PSO is modified with the help of DE. When global best of PSO remains same for large number of iterations. Then a mutant vector corresponding to random particles is generated and diversity is increased so that better results can be obtained. In this paper, difference of more than two vectors is taken to increase more randomness. The proposed approach is tested on standard functions also and results are compared with PSO.
