| 摘 要： | 针对差分进化算法全局寻优效率偏低的弱点,提出了一种基于多种群的混沌迁移策略,用以改进常规差分进化算法。该策略通过在多种群并行进化过程中引入混沌迁移序列,引导个体进行种群间的迁移。利用混沌的遍历性和随机性,保证子种群之间能够进行充分高效的信息交换。仿真实验和PID控制参数优化应用表明:该算法具有很强的全局搜索能力,寻优效率高,有效地克服了基本差分算法的早熟收敛问题。

| Abstract: | To address the premature convergence in the searching process of differential evolution,a chaotic migration-based multi-population differential evolution(CMMPDE) is proposed.In this algorithm,the asynchronic migration of individuals during parallel evolution is guided by a chaotic migration(sequence.) Because the sequence is ergodic and stochastic,information exchanging among subpopulations is ensured to be efficient and sufficient.Simulation study of CMMPDE and its application of PID control parameters opt... |
