At first , this paper in detailed analyzes the basic theory of entire searching optimized answer based genetic algorithm . aim at gene evolvement limitation of traditional genetic algorithm , this paper presents a modified genetic algorithm which on the one hand adaptively rectifies crossover and mutation probability to improve gene evolvement effect , on the other hand applies chaos sequence to regularly disorder initialization of gene . after adopting these two methods , the occurrence of prematurity phenomenal is overcome 首先,本文詳細分析了遺傳算法進行全局搜索的基本原理之后,考慮到遺傳算法在種群進化質量方面的局限性,一方面自適應地調整交叉變異概率的方法來提高種群進化質量,另一方面提出了利用混沌序列的內部有規律性對種群的初始值進行變化,這兩種措施的提出克服了遺傳算法的“早熟“現象的出現,并且仿真實驗驗證了此混沌遺傳算法的有效性。 |
