Webmodal problems. Genetic Algorithms (GA) including crowding approaches such as Deterministic Crowding (DC) and Restricted Tournament Selection (RTS) have been developed to maintain sub-populations that track these multi-modal solutions. For example, multi-modal GA’s have been used in the design of a nuclear reactor core [1]. In addition, … WebJan 21, 2016 · Several methods have been introduced into the GA’s scheme to achieve multimodal function optimization, such as sequential fitness sharing [15, 16], deterministic crowding , probabilistic crowding , clustering based niching , clearing procedure , species conserving genetic algorithm , and elitist-population strategies .
