Local Optima Correlation Assisted Adaptive Operator Selection

no code implementations3 May 2023 Jiyuan Pei, Hao Tong, Jialin Liu, Yi Mei, Xin Yao

In this paper, we propose to empirically analyse the relationship between operators in terms of the correlation between their local optima and develop a measure for quantifying their relationship.

A Hybrid Decomposition-based Multi-objective Evolutionary Algorithm for the Multi-Point Dynamic Aggregation Problem

no code implementations11 May 2021 Guanqiang Gao, Bin Xin, Yi Mei, Shuxin Ding, Juan Li

This paper focuses on a multi-objective MPDA problem which is to design an execution plan of the robots to minimise the number of robots and the maximal completion time of all the tasks.

Divide-and-Conquer Large Scale Capacitated Arc Routing Problems with Route Cutting Off Decomposition

no code implementations29 Dec 2019 Yuzhou Zhang, Yi Mei, Buzhong Zhang, Keqin Jiang

This paper proposes a novel problem decomposition operator, named the route cutting off operator, which considers the interactions between the tasks in a sophisticated way.
