混沌优化算法(COA)具有易于实现、执行时间短、具有较强的跳出局部最优机制等特点,是一种很有前途的工程应用工具。如何设计方法来改进行动方案的趋同性是一个具有挑战性的问题。提出了一种改进的变尺度并行混沌优化算法(MPCOA),并详细研究了MPCOA的三种改进方法:结合单纯形搜索法的MPCOA、基于竞争/合作互通的MPCOA、结合和声搜索法的MPCOA。仿真结果表明了这些混沌优化算法的有效性。
Chaos optimization algorithm (COA), which has the features of easy implementation, short execution time and robust mechanisms of escaping from the local optimum, is a promising tool for the engineering applications. The design of approaches to improve the convergence of the COA is a challenging issue. Improved mutative-scale parallel chaotic optimization algorithm (MPCOA) are proposed in this paper, and three ways of improvements for MPCOA are investigated in detail: MPCOA combined with simplex search method, MPCOA based on competitive/cooperative inter-communication, MPCOA combined with harmony search algorithm. Several simulation results are used to show the effective performance of these chaos optimization algorithms.
