查询词典 crossover position

The studies were either randomized trials, in which some participants were randomly assigned to cocoa or tea groups and some to control groups, or used a crossover design, in which participants' blood pressure was assessed before and after consuming cocoa products or tea.

这些研究要么随机对照临床试验，其中一些与会者随机分派到可可或茶团体和一些控制的团体，即用交叉设计，让参加者的血压是评估之前和之后食用可可制品或茶水。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作，是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等)，但是不管是采用何种交叉操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的，采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交*操作，是随机选取两个染色体进行单点交*(也可以多点交*、部分匹配交*、顺序交*和周期交*等等)，但是不管是采用何种交*操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交*运算(直接交换或经算术运算等)所得到的，采用这种交*算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

We first proprosed the method of exposing holographic plate by dividing the area with mask. In the experiment, we fabricted the elements of 1—D and 2—D butterfly, interconnection and 1—D crossover interconnection.

本首次提出并采用分区掩膜曝光制备这两种光互连全息元件的方法，在实验上制备出光学蝶互连网络的一维和二维全息元件和交叉互连网络的一维全息元件。

Paper [1]points out that GA with proportionalreproduction,adaptive crossover and mutation probabilitymeets the condition of elitist preserved GAand concludes AGAs global convergence from EGAs global convergence conclusion.At the same time,its considered the Markov chain AGA generates is inhomogeneous.

文[1]指出，具有比例复制和自适应交叉、变异操作的遗传算法满足最优保存GA的条件，则由EGA全局收敛的结论得出AGA也是全局收敛的；同时认为，AGA构成的Markov链为非时齐的。

Methods. Six rabbits were given decoctions of unprocessed licorice and honey-processed licorice in a crossover design.

Compared with the exchange and mutation operation in genetic algorithm ,crossover operation becomes helpless when adaptive value of most individules in demes have little difference.The algorithm falls into local solution and can't be solved by exchange. Although mutation can make it shake off local convergence and jump out of local solution, denteric mutation may destroy the produced module that is constructive to form the optimal solution.

相比遗传算法中的交换和变异操作，当种群的多数个体适应值相差不大时交叉操作就显得无能为力，算法陷入局部解而不能由交换解决，突然变异能够使之摆脱局部收敛而跃出局部解，但是后期的变异可能破坏已产生的对形成最优解有建设性作用的模块。

In the algorithms the tournament selection, partially matched crossover, exchanged mutation and elitist model to evolutes the individuals.
