In this lecture, we close out our discussion of "niching" diversity-preservation approaches for multi-modal and multi-objective evolutionary algorithms. We had covered clearing/clustering algorithms in the past lecture (Lecture 4B), and so we start on crowding algorithms, including Restricted Tournament Selection (RTS), briefly the introduce Species Conserving Genetic Algorithm (SCGA), and then close with a discussion of islanding approaches. This sets up an introduction to distributed (and parallel) genetic algorithms, which we will start out with in the next lecture.
