crossover rates meaning in Chinese
交换率
Examples
- 2 ) for the ability of searching , a formula of adaptive crossover rate decreasing with the increasing of genetic generation
2 )设计出余弦下降的自适应交叉率公式以改善遗传算法搜索能力。 - 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
本文引入了遗传算法来解决这一问题，提出了采用多条染色体表示一组方案的方法，并对遗传操作过程中的交叉率和变异率进行了模糊控制，有效的加快了搜索速度，避免了不成熟收敛。 - 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
简单遗传算法存在着收敛速度慢、易陷入局部极小等缺陷.针对这些缺陷，本文设计出随相对遗传代数呈双曲线下降的自适应交换率，并提出与父串间的相对欧氏距离成反比、随相对遗传代数指数下降的自适应变异率.实例验证表明，具有自适应交换率和变异率的遗传算法在收敛速度和获得全局最优解的概率两个方面都有很大的提高
