摘要

The particle swarm optimization (PSO) algorithm has exhibited good performance on well-known numerical test problems. But PSO suffers from premature convergence on multimodal test problems. J.Rige introduce Diversity-Guided Particle Swarm Optimizer (ARPSO) to improve the performance on multimodal function. As is analyzed below, test functions' gradient and dimension have an important impact on the diversity value in ARPSO evolution formula. We introduce a new PSO called Differential Dimension Guided Particle Swarm Optimization (DDPSO) to improve the performance of PSO on the high order multimodal function. Here we add two coefficients to the evolution formula of ARPSO, One is differential coefficient called dif which is proportioned to the function order. The other is dimension coefficient called dim. Then we take four benchmark multimodal functions as test function and make two experiments. Results show that DDPSO outperform ARPSO on high order multimodal function especially when the population size is small.
