在简要介绍遗传算法的基础上，通过引入种群早熟集和种群多样度的概念，分析了遗传算法中过早收敛现象的起因与特征。阐明了杂交过程的成熟化效应是引起遗传算法过早收敛的主因，提出了几种可以预防和克服过早收敛的新型遗传算法。
Based on the brief introduction of genetic algorithm, by introducing the concepts of early-maturity population and population diversity, the causes and characteristics of premature convergence in GA are analyzed. It is clarified that the maturation effect of hybridization process is the main cause of premature convergence of genetic algorithms, and several new genetic algorithms that can prevent and overcome premature convergence are proposed.
