This paper proposes a hybrid algorithm of Particle Swarm Optimization(PSO) and Artificial Fish Swarm Algorithm(AFSA) by combining the advantages of PSO algorithm and AFSA.Hybrid algorithm divides the swarm into two sub-groups.In each iteration,one sub-group evolves using PSO algorithm,the other sub-group evolves using AFSA,and two algorithms share the information of groups extremum.Through comparing PSO-AFSA hybrid algorithm with standard PSO algorithm in evolving solution to five standard functions,results show that PSO-AFSA hybrid algorithm outperforms PSO algorithm.
