Abstract: A new PSO algorithm based on the cluster analysis(CPSO) is proposed for the problem of the premature convergence by the analysis of the standard PSO.The CPSO is guaranteed that the particles are diversiform,and can make particles explore the global optimization more efficiently.The CPSO is guaranteed to converge to the global optimization solution with probability one.Finally,several examples are simulated to show that CPSO is more efficient than the standard PSO.

Key words: Particle Swarm Optimization(PSO), global optimization, convergence, cluster analysis

摘要: 在对基本PSO算法进行分析的基础上,针对PSO算法中的早熟收敛问题,提出了一种基于聚类分析的PSO算法(CPSO)。CPSO算法保证了微粒种群的多样性,使微粒能够有效地进行全局搜索。并证明了它依概率收敛于全局最优解。最后以典型的基准优化问题进行了仿真实验,验证了CPSO的有效性。
