摘要

Particle swarm optimization (PSO) is a heuristic optimization technique based on swarm intelligence, which has shown good performance in many optimization problems. However, PSO as well as other evolutionary algorithms easily fall into local minima when dealing with complex multimodal functions. This paper presents an improved PSO algorithm for solving multimodal function optimization. The proposed approach is called IPSO, which combines example-based learning mechanism and opposition-based learning concept. Simulation studies on a set of multimodal benchmark functions show that IPSO outperforms standard PSO and several other PSO variants.
