== Multimodal optimization using genetic algorithms/evolution strategies ==
De Jong's crowding method, Goldberg’sGoldberg's sharing function approach, Petrowski’sPetrowski's clearing method, restricted mating, maintaining multiple subpopulations are some of the popular approaches that have been proposed by the community. The first two methods are especially well studied, however, they do not perform explicit separation into solutions belonging to different basins of attraction.
The application of multimodal optimization within ES was not explicit for many years, and has been explored only recently.
