On the Effect of Environment-Triggered Population Diversity Compensation Methods for Memory Enhanced UMDA
This paper focuses on the effect of population diversity to environment identification-based memory scheme (EI-MMS)which heuristically compensates population diversity through the storage and retrieving process of historic information.We introduced several diversity compensation measures and combined them with EI-MMS based univariate marginal distribution algorithm (UMDA)from two aspects.First,a basic diversity compensation measure was used to fight against the inherent diversity loss of UMDA.Second,two environment-triggered compensation measures were added in the sense of dynamic environment.Based on the experimental results on three dynamic test problems,the dynamics of population diversity of the corresponding EI-MMS based UMDAs were analyzed and several conclusions about how does the population diversity affect the performance of the algorithm in dynamic environments were drawn.
