AI总结:

本文对多目标存档进行了系统概述,填补了缺乏理论视角研究的空白,并证明了基于弱Pareto兼容指标的存档算法在设计得当的情况下,可实现与基于Pareto兼容指标的存档器相同的理论理想特性(如极限最优)。

摘要:

大多数多目标优化算法在搜索过程中显式或隐式地维护一个存档。这种存档可以仅用于存储呈现给决策者的高质量解,但在许多情况下,它也可能参与搜索过程(例如,在进化计算中作为种群)。在过去的二十年中,存档——即将新解与先前的解进行比较并决定如何更新存档/种群的过程——已成为进化多目标优化(EMO)中的一个重要问题。社区不断致力于开发各种有效的存档方法,从传统的基于Pareto的方法到最近基于指标和基于分解的方法,这证明了这一点。然而,这些努力的重点是针对特定质量指标的经验性能比较;缺乏从一般理论角度对存档方法的系统研究。在本文中,我们尝试对多目标存档进行系统概述,希望为从理论和实践的整体角度理解存档算法铺平道路,更重要的是,为如何设计理论上理想且实际有用的存档算法提供指导。在此过程中,我们还表明,基于弱Pareto兼容指标(例如,epsilon-indicator)的存档算法,只要设计得当,就能实现与基于Pareto兼容指标(例如,超体积指标)的存档器相同的理论理想特性。这些理想特性包括属性极限最优,这是有界存档算法在解集之间最一般形式的优越性方面可能具有的最优属性的极限形式。

英文摘要:

Most multi-objective optimisation algorithms maintain an archive explicitly or implicitly during their search. Such an archive can be solely used to store high-quality solutions presented to the decision maker, but in many cases may participate in the search process (e.g., as the population in evolutionary computation). Over the last two decades, archiving, the process of comparing new solutions with previous ones and deciding how to update the archive/population, stands as an important issue in evolutionary multi-objective optimisation (EMO). This is evidenced by constant efforts from the community on developing various effective archiving methods, ranging from conventional Pareto-based methods to more recent indicator-based and decomposition-based ones. However, the focus of these efforts is on empirical performance comparison in terms of specific quality indicators; there is lack of systematic study of archiving methods from a general theoretical perspective. In this paper, we attempt to conduct a systematic overview of multi-objective archiving, in the hope of paving the way to understand archiving algorithms from a holistic perspective of theory and practice, and more importantly providing a guidance on how to design theoretically desirable and practically useful archiving algorithms. In doing so, we also present that archiving algorithms based on weakly Pareto compliant indicators (e.g., epsilon-indicator), as long as designed properly, can achieve the same theoretical desirables as archivers based on Pareto compliant indicators (e.g., hypervolume indicator). Such desirables include the property limit-optimal, the limit form of the possible optimal property that a bounded archiving algorithm can have with respect to the most general form of superiority between solution sets.
