摘要: 提出一种择优学习的多个体差分算法用于求解约束优化问题,目的是用来提高差分算法的搜索能力。首先,将择优学习策略应用到混合变异算子中,使其快速搜索到可行解区域,然后使用克隆策略加大对最优解区域的搜索力度,增强局部搜索能力。通过对CEC2006经典Benchmark函数测试,实验结果表明本算法在求解效率和精度上都取得了较好的结果。

Abstract: This paper presents a preferred learning-based multiple individuals differential evolution algorithm for solving constrained optimization problems, in order to improve the search ability of difference evolution algorithm. Firstly, a kind of preferred learning strategy is applied to the hybrid mutation operator, which makes it quickly search to the area of feasible solution, then the clone strategies are used to enhance the search intensity in optimal solution area and the ability of local search is greatly improved. Finally the algorithm is tested on the CEC2006 classic Benchmark function, the experimental results show that the algorithm is of better results in solving efficiency and accuracy.
