Generative Model-Based Large-Scaled Dynamic Multiobjective Optimization

Dynamic multi-objective optimization problems (DMOPs) are often scaled to large-scale scenarios in real-world applications, which inevitably must face the triple challenges of massive search space, dynamic environmental changes and multi-objective conflicts simultaneously. This talk will survey generative modeled-based approaches, specifically an adversarial autoencoder-based large-scale dynamic multi-objective evolutionary framework. It integrates deep generative modeling techniques and large-scale multi-objective evolutionary algorithms to solve large-scale DMOPs effectively and efficiently. Specifically, a deep generative network training architecture is proposed for high-dimensional decision variables in large-scale DMOPs. It can transfer a generative model trained on Pareto-optimal solutions in the current environment to a new environment using only the auxiliary information exhibited through the movement trajectories of historical Pareto-optimal solutions, resulting in the generation of quality initial populations for the new environment. Meanwhile, any large-scale multi-objective evolutionary algorithm can be integrated into the proposed framework without extensive modifications. Experimental results on a typical dynamic multi-objective test suite with problem settings from 30 to 1,000 dimensions demonstrate that the optimization performance of the proposed framework outperforms existing state-of-the-art designs. Especially in large-scale scenarios, the proposed framework is considered superior in terms of solution quality and computational efficiency.
