摘要:

针对高维多目标优化问题,提出了一种新的排序方法.它通过产生近似最优目标向量来增加种群的规模,从而达到对真实个体的有效排序.首先构造一个理想的帕累托前沿面,然后将这个理想的帕累托前沿面分成若干个网格,使每个个体都对应惟一的一个网格,通过这个网格上的节点来判断这个体是不是非支配解.数值实验表明,即使对于50维目标的问题,收敛性度量值也小于1.此外,与当前的两种最具代表性的松弛的帕累托占优方法比较,该方法能同时保持解的多样性和收敛性.

关键词: 高维多目标优化, 进化算法, 排序, 帕累托最优

Abstract:

A new ranking method is proposed to solve many-objective optimization problems. It can be used to generates many approximate optimal objective vectors to increase the size of population, so that the individuals can be efficiently sorted by using non-dominance sorting. An ideal Pareto Front is first constructed, and then the ideal Pareto Front is divided into a number of grids. For each individual, it is uniquely assigned to a grid, and then some nodes of the grid are used to determine whether the individual is a non-dominance solution. Experimental results show that, even for 50-objective optimization problems, the convergence measurements of solutions obtained by the ranking method are smaller than 1. Meanwhile, compared with two state-of-the-art relaxed forms of Pareto dominance, the experimental results show that this ranking method can simultaneously maintain the diversity of solutions and have good convergence.

Key words: many-objective optimization, evolutionary algorithms, ranking, Pareto optimisation
