Abstract:

Evolutionary many-objective optimization is a hot topic in the evolutionary computation community. A large number of new algorithms as well as a variety of modifications of existing algorithms have been proposed for the efficient handling of multi-objective problems with four or more objectives. In this presentation, first we check the increasing popularity of evolutionary many-objective optimization. Next, after briefly explaining the basic idea of evolutionary multi-objective optimization, we overview some well-known difficulties in many-objective optimization: search for Pareto optimal solutions, approximation of the entire Pareto front, presentation of a large number of non-dominated solutions, choice of a single final solution, and examination of the search behavior of evolutionary algorithms. Then we explain representative approaches to evolutionary many-objective optimization: modification of Pareto dominance, dimensionality reduction, incorporation of preference information, indicator-based algorithms, and decomposition-based algorithms. Our main focus is on the current trend in the field of evolutionary many-objective optimization, which is the proposal of new decomposition-based algorithms and their performance evaluation using DTLZ and WFG test problems. Finally, for discussing promising future research directions, we examine the following two issues: (i) choice of many-objective test problems and (ii) specifications in performance indicators. More specifically, we explain that the performance of recently proposed decomposition-based algorithms strongly depends on the choice of test problems as well as the specifications of reference points for the hypervolume (HV) and inverted generational distance (IGD) indicators. Examinations of these issues clearly show the importance of the following future research directions: proposal of a wide variety of many-objective test problems, examination of the reality of test problems (i.e., their relevance to real-world problems), development of a robust search mechanism with good performance over a wide variety of test problems with no adaptation, and development of an efficient adaptation mechanism of search strategies to a different test problem.
