recommendations! Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-85233-6

Abstract: This paper presents a surrogate-assisted global and distributed local collaborative optimization (SGDLCO) algorithm for expensive constrained optimization problems where two surrogate optimization phases are executed collaboratively at each generation. As the complexity of optimization problems… read more here.

recommendations! Published in 2025 at "IEEE Transactions on Systems, Man, and Cybernetics: Systems"

DOI: 10.1109/tsmc.2024.3504728

Abstract: This article proposes a constrained evolutionary Bayesian optimization (CEBO) algorithm to cope with expensive constrained optimization problems with inequality constraints. The uniqueness of CEBO lies in its capability of balancing feasibility and objective improvement under… read more here.

DOI: 10.1109/tsmc.2025.3573195

Abstract: For expensive constrained optimization problems (ECOPs), the evaluation of the objective and constraints are both expensive. Due to the low computational cost of the surrogate model and the excellent search capabilities of evolutionary algorithms, surrogate-assisted… read more here.
