HV-Net: Hypervolume Approximation based on DeepSets

no code implementations4 Mar 2022 Ke Shang, WeiYu Chen, Weiduo Liao, Hisao Ishibuchi

In this letter, we propose HV-Net, a new method for hypervolume approximation in evolutionary multi-objective optimization.

Clustering-Based Subset Selection in Evolutionary Multiobjective Optimization

no code implementations19 Aug 2021 WeiYu Chen, Hisao Ishibuchi, Ke Shang

Subset selection is an important component in evolutionary multiobjective optimization (EMO) algorithms.

Hypervolume-Optimal $μ$-Distributions on Line/Plane-based Pareto Fronts in Three Dimensions

no code implementations20 Apr 2021 Ke Shang, Hisao Ishibuchi, WeiYu Chen, Yang Nan, Weiduo Liao

Then, we show that a uniform solution set on the plane-based Pareto front is not always optimal for hypervolume maximization.

Fast Greedy Subset Selection from Large Candidate Solution Sets in Evolutionary Multi-objective Optimization

1 code implementation1 Feb 2021 WeiYu Chen, Hisao Ishibuchi, Ke Shang

Especially, in an EMO algorithm with an unbounded external archive, subset selection is an essential post-processing procedure to select a pre-specified number of solutions as the final result.
