摘    要:基本粒子群优化算法存在着"早熟"现象。究其主要原因是由于全局最优粒子的运动形式滞留在局部最优。为此,根据基本PSO算法的特点,在粒子运动过程中加入了个体小概率随机变异,增强了粒子运动形式改变能力,减小了陷入局部最优的可能性。通过数值计算结果表明,该方法能有效地解决粒子群优化"早熟"问题。

关 键 词:粒子群优化算法  随机变异  早熟  遗传算法

Abstract:Standard Particle Swarm Optimization(PSO) has premature phenomenon,and the reason is that the motion of the globe best particle plunges into local optimization.Thinking over this point,we add the small probability random mutation to strengthen the motion of the particles,reduce the chance of slumping local optimization.The result of numerical computation shows that the modified algorithm can resolve the premature problem of PSO efficiently.
Keywords:PSO  random mutation  premature  genetic algorithm
