摘要
为了加强粒子群算法的搜索能力,利用环状网络拓扑的概念来改良粒子族群相互连结的行为模式,提出基于环状拓扑机制的粒子群算法(RTPSO),将其应用于有约束条件的工程结构设计问题,例如悬臂梁问题,并与其他优化算法比较。测试结果显示,加入了环状拓扑策略的RTPSO比基本PSO算法运算更加稳定快速,且与其他方法比较,RTPSO不仅能更精确地搜索到问题最优解,而且有更高的计算效率。
To improve the performance of PSO algorithm,introduces the concept of RTPSO to solve constrained structural design problem,such as cantilevered beam design problem.The result shows that the searching performance,such as reliability and convergent speed are better than those of the standard PSO.Through comparing RTPSO and several other methods,the RTPSO can not only find more accurately final solution to the problem,but also has higher computation efficiency.
