遗传算法作为一种功能强大的随机搜索算法被广泛地应用在许多领域,但是进化效率低下问题始终是困扰用户的一个主要问题,“进化停滞”即是它的表现之一。本文分析了“进化停滞”问题产生的机理,并给出了合理的解决方案。 Genetic algorithm as a powerful random search algorithm is widely used in many fields, but the problem of low evolutionary efficiency has always been a major problem for users, “evolutionary stagnation ” is one of its manifestations. This paper analyzes the mechanism of the problem of “evolution stagnation” and gives a reasonable solution.
