This paper proposed a dynamic crowding distance(DCD) based on diversity maintenance strategy,in which the definition of individual's DCD was based on the degree of difference between the crowding distances on different objectives.The proposed strategy computed individuals' DCD dynamically during the process of population maintenance.Compared with NSGA-II and e-MOEA,the experimental results demonstrate that DCD can improve diversity at a high level.
