Stable matching-based selection models the selection process in MOEA/D as a stable marriage problem. By finding a stable matching between the sub problems and solutions, the solutions are assigned to sub problems to balance the convergence and the diversity. In this paper, a two-level stable matching-based selection is proposed to further guarantee the diversity of the population. More specifically,...
Combining ant colony optimization (ACO) and the multiobjective evolutionary algorithm (EA) based on decomposition (MOEA/D), this paper proposes a multiobjective EA, i.e., MOEA/D-ACO. Following other MOEA/D-like algorithms, MOEA/D-ACO decomposes a multiobjective optimization problem into a number of single-objective optimization problems. Each ant (i.e., agent) is responsible for solving one subproblem...
Based on the Proximate Optimality Principle in metaheuristics, a Population Based Guided Local Search (P-GLS) framework for dealing with difficult combinatorial optimization problems is suggested in this paper. In P-GLS, several guided local search (GLS) procedures (agents) run in a parallel way. These agents exchange information during some time points in the search. The information exchanged is...
