Title

Constraint Handling in Multi-Objective Optimization

Motivation

Multi-objective evolutionary algorithms (MOEAs) have been intensively studied and successfully applied to many engineering problems. Since most real-world application problems involve constraint conditions as well as multiple objectives, evolutionary algorithms are requested to efficiently and effectively handle constraint conditions and multiple objectives simultaneously. This leads to several proposals of constraint handling methods for MOEAs. For example, some constraint handling methods utilize constraint violations in addition to objective values for the ranking of feasible and infeasible solutions in the current population. Other constraint-handling methods are based on repair procedures to generate feasible solutions from infeasible ones. Several ideas have been proposed to efficiently utilize infeasible solutions to drive the multiobjective search to promising regions in the search space and/or to escape from local optima. Constraint-handling methods often have a dominant effect on the search performance of MOEAs in constrained multi-objective optimization problems.

Over the past two decades, a considerable number of studies have been conducted on MOEAs. However, the number of studies about constraint-handling in MOEAs is still not enough. To fully develop a potential utility of evolutionary multi-objective optimization, this special session focuses on constraint-handling especially in evolutionary multi-objective optimization.
