摘要
较弱的局部搜索能力是影响扩展的微粒群算法(EPSO)性能的重要因素。为了提高扩展微粒群算法的局部搜索能力,本文针对EPSO的特点设计了各种静态有向种群结构。通过研究静态有向种群结构的特征度量与EPSO算法性能的关系,得出微粒的出度值和适应值是影响EPSO局部搜索与全局搜索能力的重要因素等结论。
The weak local searching capability is an important factor influencing the performance of Extended Parti- cle Swarm Optimization （EPSO）algorithm. In order to improve the local search capability of EPSO, various static directed structures were inves according to the characteristics of EPSO. Some conclusions such as the impor- tant factor influence of outdegree of nodes and the particles fitness values on the global and the local search capa- bility of EPSO, were drawn in simulation experiment by studying the relations among characteristics measures of static directed structures and performances of EPSO.
