Lie Meng Pang, Hisao Ishibuchi, Ke Shang

摘要:

发展高效的进化多目标优化(EMO)算法一直是演化计算界的研究热点。多年来,已经提出了许多EMO算法。现有的EMO算法主要是基于最终种群框架开发的。在最终种群框架中,EMO算法的最终种群呈现给决策者。因此,要求EMO算法产生的最终种群是一个好的解集。最近,使用的解决方案选择框架的EMO算法的设计建议。这个框架有一个无限的外部存档来存储所有检查过的解决方案。从档案中选择预先指定数量的解决方案作为提交给决策者的最终解决方案。当使用解决方案选择框架时,EMO算法可以以更灵活的方式设计,因为最终群体不一定是好的解决方案集。在本文中,我们研究了这两个框架下的MOEA/D的设计。我们使用离线遗传算法为基础的超探试法,以找到最佳的配置MOEA/D在每个框架。实验中使用了DTLZ和WFG测试集及其减版本。实验结果表明,一个更灵活的,鲁棒性和高性能的MOEA/D算法时,可以得到的解决方案选择框架。

英文摘要:

The development of efficient and effective evolutionary multi-objective optimization (EMO) algorithms has been an active research topic in the evolutionary computation community. Over the years, many EMO algorithms have been proposed. The existing EMO algorithms are mainly developed based on the final population framework. In the final population framework, the final population of an EMO algorithm is presented to the decision maker. Thus, it is required that the final population produced by an EMO algorithm is a good solution set. Recently, the use of solution selection framework was suggested for the design of EMO algorithms. This framework has an unbounded external archive to store all the examined solutions. A pre-specified number of solutions are selected from the archive as the final solutions presented to the decision maker. When the solution selection framework is used, EMO algorithms can be designed in a more flexible manner since the final population is not necessarily to be a good solution set. In this paper, we examine the design of MOEA/D under these two frameworks. We use an offline genetic algorithm-based hyper-heuristic method to find the optimal configuration of MOEA/D in each framework. The DTLZ and WFG test suites and their minus versions are used in our experiments. The experimental results suggest the possibility that a more flexible, robust and high-performance MOEA/D algorithm can be obtained when the solution selection framework is used.
