Summary: This paper proposes a double-balanced evolutionary multi-task optimization (DBEMTO) algorithm to better solve constrained multi-objective optimization problems (CMOPs). DBEMTO evolves two populations to solve the main task (CMOP) and the auxiliary task (MOP extracted from the CMOP) respectively and uses three evolutionary strategies for offspring generation. DBEMTO has performed more competitively compared to other state-of-the-art CMOEAs according to the final results.

Summary: This article explores and utilizes the relationship between constrained Pareto front (CPF) and unconstrained Pareto front (UPF) to solve constrained multiobjective optimization problems (CMOPs). A new constrained multiobjective evolutionary algorithm (CMOEA) is presented by dividing the evolutionary process into learning stage and evolving stage. Experimental results show that the proposed method has better performance compared to state-of-the-art CMOEAs, indicating the promising use of the relationship between CPF and UPF in solving CMOPs.

Summary: In this article, an evolutionary algorithm with constraint relaxation strategy based on differential evolution algorithm (CRS-DE) is proposed to solve Highly Constrained Multiobjective Optimization Problems (HCMOPs). The algorithm relaxes the constraints by dividing the infeasible solutions into semifeasible subpopulation (SF) and infeasible subpopulation (IF), and devises corresponding reproduction and selection strategies for SF, IF, and feasible subpopulations. To prevent premature convergence, a mobility restriction mechanism is developed to restrict the individuals in SF and IF from entering the feasible subpopulation and enhance the diversity of the whole population.

Summary: Balancing convergence and diversity is a challenge in multi-objective optimization problems, especially when the proportion of feasible regions is low. This paper proposes a constrained multi-objective optimization algorithm based on a hybrid driven strategy to enhance the feasibility and diversity performance of Pareto solutions. The algorithm outperforms peer algorithms, especially in large-infeasible-regions multi-objective optimization problems.

Summary: This article proposes a cooperative multiobjective evolutionary algorithm with propulsive population (CMOEA-PP) to solve constrained multiobjective optimization problems (CMOPs), balancing convergence, diversity, and feasibility through the collaboration between propulsive population and normal population. Propulsive population focuses on convergence, while normal population prioritizes feasibility and must maintain diversity.

Summary: The existence of constrained multi-objective optimization problems (CMOPs) has led researchers to develop constrained multi-objective evolutionary algorithms (CMOEAs). In order to handle CMOPs with discontinuous feasible regions or infeasible barriers, a novel Dual-Population and Multi-Stage based Constrained Multi-objective Evolutionary Algorithm (CMOEA-DPMS) is proposed, along with a new constraint handling technique (CHT) called decomposition based constraint non-dominating sorting (DCDSort) to maintain feasibility, convergence, and diversity.

Summary: Many domination-based multi-objective evolutionary algorithms are designed for constrained multi-objective optimization problems, but balancing feasibility, convergence, and distribution remains a challenge. The proposed MODE-CHS algorithm addresses this issue by using constraint-handling switching to enhance population convergence and obtain feasible solutions, while also involving an external archive and offspring in the evolution process to improve distribution. Experimental results demonstrate that MODE-CHS is competitive in solving CMOPs compared to other state-of-the-art algorithms.

Summary: This study introduces a problem transformation technique to handle both constraints and optimize objectives simultaneously in constrained many-objective optimization problems (CMaOPs). The well-known reference-point-based NSGA-III is tailored under the problem transformation model as DCNSGA-III to solve CMaOPs effectively. Through the design of a mating selection mechanism and an environmental selection operator, the proposed algorithm generates and selects high-quality epsilon-feasible offspring solutions.

Summary: The article presents a framework called MODAct for designing electro-mechanical actuators and derives 20 constrained multiobjective optimization test problems from it. The effects of constraints on the Pareto front and convergence performance are analyzed, and a constraint landscape analysis approach with three new metrics is utilized to characterize the search and objective spaces. Comparison of MODAct features with existing test suites highlights differences and suggests that design problems are challenging due to constraints.

Summary: Constrained multi-objective optimization problems are challenging to handle due to the complexities of objectives and constraints. To address this issue, a multi-stage evolutionary algorithm is proposed in this paper, which gradually adds constraints and sorts their handling priority based on their impact on the Pareto front. Experimental results demonstrate that the proposed algorithm outperforms state-of-the-art algorithms in dealing with complex constraint problems.
