摘要: 标准粒子群算法在求解多维多峰函数问题时,存在局部寻优精度不高、全局寻优能力不强和收敛速度慢的缺点,为此提出一种基于适应值分析的智能粒子群算法。该算法引入“局部适应值参数”、“全局适应值参数”和“坐标轮换法”思想,经过对3个多维多峰函数的测试,表明该算法兼顾了局部和全局搜索,并拥有较快的收敛速度。

Abstract: When solving multi-dimensional multi-peaks function problems, the standard particle swarm optimization algorithm is not good at local search with high accuracy and its global search ability is also weak, besides, its convergence rate is slow. Therefore, an intelligent particle swarm optimization algorithm based on fitness analysis is presented, into which the “local fitness parameter”, the “global fitness parameter” and the “coordinate rotation method” are introduced. Three multi-dimensional multi-peaks functions are tested to show that this algorithm not only has the ability of local and global search, but also demonstrates faster convergence rate.

Key words: particle swarm optimization, fitness parameters, coordinate rotation
