比例选择 meaning in English
proportional selection
Examples
- When solving independent problems , the mathematical analysis shows that when a schema whose fitness is higher than the overall average fitness , the schema ' s exponential increase index of trials allocated in the next generations of coevolutionary genetic algorithm ( cga ) is higher than that of csga
数学分析表明，对于独立多问题，共同进化算法采用按比例选择策略时，高于平均适应值的模式的逐代递增指数高于传统单种群遗传算法，说明共同进化算法的效率高于传统的单种群遗传算法。 - Based on the genetic algorithm ' s global searching capability with probability regulation and euclid ' s space distance metric to settle multi - objective , the algorithm that integrates multi - objective ' s decision - making into the modified genetic algorithm to solute the optimal model with discrete variables and multi - objective is proposed . during the algorithm ' s design , the euclid ' s space distance metric is proposed to transform the multi - objective problem into single objective problem . and some modified measure to fitness function and crossover probability and mutation probability are used to improve the performance of the algorithm and avoid premature convergence
算法设计过程中，利用欧几里德空间距离准则和罚函数法，将含有约束条件的多目标规划问题转化为无约束的单目标优化问题；针对简单遗传算法出现的早熟，构造随进化代数动态调整适应度的适应度函数和随个体适应度自适应调整的交叉、变异概率；提出比例选择与精英保留策略相结合的选择、两点交叉和简单变异的改进遗传算法。
