commutative law
crossover rates
exchange rate
exchange ratio
rate of interchange
Examples
- A method of determining air change rates in detached dwellings
独立住宅空气交换率测定方法 - Running will achieve following benefits : 1 : higher dye - liquor and fabric exchange rate 2 : higher dyeing chemical exhaustion rate
上色交换率高，自然均染度及得色率也会很高。 - We analyze the effect of these parameters to the esos price including non - circulated stock , circulated stock , the whole share of stock , the transforming rate and state variable
而且中国股权结构下esos的价值与股票总数,交换率以及流通股数同方向变化,与非流通股数反方向变化。 - ( 4 ) for the first time introduced jieke theory in water resources system , analyzed character parameter of water resources system jieke , included opening degree , exchange rate , thickness and magnitude . established importance theory foundation for quantify research of water resources system perimeter control
（ 4 ）首次将界壳论引人水资源系统，分析了水资源系统界壳的特征参量，这些控制参量包括界壳开放度、界壳交换率、界壁厚度以及界门大小等，为水资源系统周界控制的定量化研究奠定重要的理论基础。 - 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
