摘要: 将Pareto适应度遗传算法(PFGA)与局部搜索相结合,提出了一种用于求解多目标组合优化问题的改进算法IPFGA,该算法基于Pareto支配关系对遗传操作产生的每一个个体进行局部搜索,并采取在外部群体中引入拥挤距离的精英选择策略。实验结果表明,与PFGA相比,IPFGA有更快的收敛速度。

Abstract: Combining Pareto Fitness Genetic Algorithm(PFGA) with local search,an Improved Pareto Fitness Genetic Algorithm(IPFGA) for multi-objective combinatorial optimization is proposed.In the proposed algorithm,a local search procedure is applied to each solution generated by genetic operations.The concept of Pareto dominance is used in the local search procedure,and the idea of crowding distance in the external population is used to perform elitism.The experimental results show that the IPFGA,compared with the known PFGA,has faster convergent speed.
