关于PSO方法中粒子运行轨迹的修正

A Revise on Particle Trajectories of Particle Swarm Optimization

粒子群优化方法(PSO Particle Swarm Optimization)由Kennedy和Eberhart于1995年提出,基于群体智能行为的演化计算方法,并广泛应用于各类优化问题。在一些研究中,对PSO的粒子收敛性及粒子运行轨迹进行了分析,有一定理论价值和指导意义,本文针对一些分析过程中存在的问题进行了讨论,并对相关结论进行了修正。

Particle Swarm Optimization （PSO）method was proposed by Kennedy and Eberhart in 1995, it can be used to solve a wide array of different optimization. The convergence properties and trajectories of particles are studied in some research which has great theoretical value and significance. But there is a series of problems in those researches. Some problems on particle trajectories of particle swarm optimization are discussed and revised in this paper.
