WebJun 15, 2016 · Evolutionary algorithms (EAs) tend to converge to a single solution as the diversity of the population diminishes .This behavior is known as genetic drift.Any technique that maintains diversity in the population based on the distance between the population members is called a Niching technique.. Fitness sharing is a type of Niching, where … WebEvolutionary inspired heuristics suffer from a premature convergence at local optima and, consequently, a population diversity loss. Thus, breaking out of a local optimum trap and crossing saddles between optima in multimodal and multidimensional search spaces is an important issue in an evolutionary optimization algorithm.
