| 摘 要： | 结合对粒子群优化算法收敛性的分析,针对算法在寻优过程中容易出现的早熟现象,提出了一种带压缩因子的自适应权重粒子群算法.该算法以目标函数值的改变为信息,动态设置惯性权重值,使算法达到全局寻优和局部探索之间的有效平衡.仿真实验表明该算法能有效抑制寻优过程中的早熟现象.

| Abstract: | In global optimization process,common particle swarm optimization algorithm can easily fall into the local optimization arising from the phenomenon of prematurity.Through an analysis of its convergence,this paper presents an adaptive weight particle swarm optimization algorithm with the compression coefficient.The algorithm changes the value of the objective function for the information to change the value,so that the algorithm may reach an effective balance between global optimization and local exploration... |
