Distributed Evolution Strategies with Multi-Level Learning for Large-Scale Black-Box Optimization

no code implementations9 Oct 2023 Qiqi Duan, Chang Shao, Guochen Zhou, Minghan Zhang, Qi Zhao, Yuhui Shi

In the post-Moore era, main performance gains of black-box optimizers are increasingly depending on parallelism, especially for large-scale optimization (LSO).

Cooperative Coevolution for Non-Separable Large-Scale Black-Box Optimization: Convergence Analyses and Distributed Accelerations

1 code implementation11 Apr 2023 Qiqi Duan, Chang Shao, Guochen Zhou, Haobin Yang, Qi Zhao, Yuhui Shi

Given the ubiquity of non-separable optimization problems in real worlds, in this paper we analyze and extend the large-scale version of the well-known cooperative coevolution (CC), a divide-and-conquer black-box optimization framework, on non-separable functions.

Automated Design of Metaheuristic Algorithms: A Survey

no code implementations12 Mar 2023 Qi Zhao, Qiqi Duan, Bai Yan, Shi Cheng, Yuhui Shi

Metaheuristics have gained great success in academia and practice because their search logic can be applied to any problem with available solution representation, solution quality evaluation, and certain notions of locality.

AutoOptLib: Tailoring Metaheuristic Optimizers via Automated Algorithm Design

1 code implementation12 Mar 2023 Qi Zhao, Bai Yan, Taiwei Hu, Xianglong Chen, Qiqi Duan, Jian Yang, Yuhui Shi

In response, this paper proposes AutoOptLib, the first platform for accessible automated design of metaheuristic optimizers.
