WebAug 5, 2024 · In Evolutionary Robotics a population of solutions is evolved to optimize robots that solve a given task. However, in traditional Evolutionary Algorithms, the population of solutions tends to converge to local optima when the problem is complex or the search space is large, a problem known as premature convergence. WebJun 22, 2024 · The loss of diversity (also called genetic drift) in evolutionary algorithms is a phenomenon that has been studied since the early origins of the field.Such studies have given rise to a variety of mechanisms that allow maintaining a diversity of solutions within the population of an evolutionary algorithm for a long time.
