Improving Performance Insensitivity of Large-scale Multiobjective Optimization via Monte Carlo Tree Search

no code implementations8 Apr 2023 Haokai Hong, Min Jiang, Gary G. Yen

In this work, we propose an evolutionary algorithm for solving LSMOPs based on Monte Carlo tree search, the so-called LMMOCTS, which aims to improve the performance and insensitivity for large-scale multiobjective optimization problems.

Efficiently Tackling Million-Dimensional Multiobjective Problems: A Direction Sampling and Fine-Tuning Approach

no code implementations8 Apr 2023 Haokai Hong, Min Jiang, Qiuzhen Lin, Kay Chen Tan

To sample the most suitable evolutionary directions for different solutions, Thompson sampling is adopted for its effectiveness in recommending from a very large number of items within limited historical evaluations.

Balancing Exploration and Exploitation for Solving Large-scale Multiobjective Optimization via Attention Mechanism

no code implementations20 May 2022 Haokai Hong, Min Jiang, Liang Feng, Qiuzhen Lin, Kay Chen Tan

However, these algorithms ignore the significance of tackling this issue from the perspective of decision variables, which makes the algorithm lack the ability to search from different dimensions and limits the performance of the algorithm.

Solving Large-Scale Multi-Objective Optimization via Probabilistic Prediction Model

no code implementations16 Jul 2021 Haokai Hong, Kai Ye, Min Jiang, Donglin Cao, Kay Chen Tan

At the same time, due to the adoption of an individual-based evolution mechanism, the computational cost of the proposed method is independent of the number of decision variables, thus avoiding the problem of exponential growth of the search space.

Manifold Interpolation for Large-Scale Multi-Objective Optimization via Generative Adversarial Networks

no code implementations8 Jan 2021 Zhenzhong Wang, Haokai Hong, Kai Ye, Min Jiang, Kay Chen Tan

However, traditional evolutionary algorithms for solving LSMOPs have some deficiencies in dealing with this structural manifold, resulting in poor diversity, local optima, and inefficient searches.
