Fitness, Selection, and Population Management

Abstract

As explained in Chap. 3, there are two fundamental forces that form the basis of evolutionary systems: variation and selection. In this chapter we discuss the EA components behind the second one. Having discussed some typical population management models, and selection operators, we then go on to explicitly look at some situations where diversity is needed, such as multimodal problems, and some approaches to population management, and altering selection, that have been proposed to increase useful diversity.
