A new Hybrid Population Migration Algorithm based on Powell Method

为避免人口迁移算法存在收敛速度慢,易陷入局部最优等缺陷,文章提出了一种基于Powell法的人口迁移混合算法.利用Powell法强大的局部优化能力提高算法的优化精度,增强算法的稳定性.实验结果表明,改进后的算法全局搜索能力更强,求解精度更高,性能更稳定.

In order to avoid the deficiencies such as slow convergence and easily to fall into local optimum of PMA,this paper proposes a hybrid optimization algorithm based on Powell method.It uses the powerful ability of Powell method to increase the local optimization accuracy,and enhance the stability of the algorithm effectively.Simulation results illustrate that the hybrid algorithm has a stronger global search ability and a high solution precision,also with a stable performance.
