  1. Simple genetic algorithm gets local minimization too easily and converges slowly. to solve these problems, adaptive crossover rate that has reverse hyperbolic rel ation with the numbers of iteration is designed, and adaptive mutation rate that has reverse proportion to the distances of parents and reverse exponential relat ion to the numbers of iteration is put forward. the practical simulation results show that the adaptive ga has greater convergence speed and larger probability o f getting the best solution

    簡單遺傳演算法存在著收斂度慢、易陷入局部極小等缺陷.針對這些缺陷,本文設計出隨相對遺傳代數呈雙下降的自適應交換,並提出與父串間的相對歐氏成反比、隨相對遺傳代數指數下降的自適應變異.實例驗證表明,具有自適應交換和變異的遺傳演算法在收斂度和獲得全局最優解的概兩個方面都有很大的提高
