交換率
例句與用法
- 2 ) for the ability of searching , a formula of adaptive crossover rate decreasing with the increasing of genetic generation
2 )設計出余弦下降的自適應交叉率公式以改善遺傳算法搜索能力。 - Genetic algorithm is adopted to solve this problem . the method using several chromosomes express a scheme is presented . crossover rate and mutation rate are automatically adjusted by fuzzy control to quicken search procedure and avoid immature convergence
本文引入了遺傳算法來解決這一問題，提出了采用多條染色體表示一組方案的方法，并對遺傳操作過程中的交叉率和變異率進行了模糊控制，有效的加快了搜索速度，避免了不成熟收斂。 - 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
簡單遺傳算法存在著收斂速度慢、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曲線下降的自適應交換率，并提出與父串間的相對歐氏距離成反比、隨相對遺傳代數指數下降的自適應變異率.實例驗證表明，具有自適應交換率和變異率的遺傳算法在收斂速度和獲得全局最優解的概率兩個方面都有很大的提高
