Modified particle swarm optimization for unconstrained optimization

This paper presents a modified particle swarm optimization (PSO) algorithm to improve the performance of standard PSO. The proposed approach is called HPSO, which modifies the original velocity updating equation of PSO. In order to verify the performance of HPSO, we test it on ten well-known benchmark optimization functions. The simulation results show that HPSO obtains better performance than standard PSO on majority of test functions.
