Data-Driven Evolutionary Multi-Objective Optimization Based on Multiple-Gradient Descent for Disconnected Pareto Fronts

no code implementations28 May 2022 Renzhi Chen, Ke Li

Data-driven evolutionary multi-objective optimization (EMO) has been recognized as an effective approach for multi-objective optimization problems with expensive objective functions.

Batched Data-Driven Evolutionary Multi-Objective Optimization Based on Manifold Interpolation

no code implementations12 Sep 2021 Ke Li, Renzhi Chen

Data-driven evolutionary optimization can be used to search for a set of non-dominated trade-off solutions, where the expensive objective functions are approximated as a surrogate model.

Interactive Decomposition Multi-Objective Optimization via Progressively Learned Value Functions

no code implementations2 Jan 2018 Ke Li, Renzhi Chen, Dragan Savic, Xin Yao

In the preference elicitation session, the preference information learned in the consultation module is translated into the form that can be used in a decomposition-based EMO algorithm, i. e., a set of reference points that are biased toward to the ROI.

Dynamic Multi-Objectives Optimization with a Changing Number of Objectives

no code implementations23 Aug 2016 Renzhi Chen, Ke Li, Xin Yao

Existing studies on dynamic multi-objective optimization focus on problems with time-dependent objective functions, while the ones with a changing number of objectives have rarely been considered in the literature.
