摘要
Crowding distance is an index for measuring the diversity of solutions. However, in many cases, it may fail to identify individuals with better diversity. The reason is that crowding distance mainly takes advantage of the local information of each position. To tackle this issue, based on the global position information of entire population, this paper designs average-distance-clustering diversity index, and further proposes NSGA-II with average distance clustering (ADCNSGA-II). ADCNSGA-II divides the entire population into several small populations using average distance, then the selection, crossover and mutation operators are performed in each small population. Simulation results show the proposed algorithm can maintain the diversify effectively. Copyright © 2021 Acta Automatica Sinica. All rights reserved.
