crossover.m

用matlab编写的二进制的遗传算法程序.rar

%交叉操作
function [NewPop]=CrossOver_decimal(OldPop,pcross)%OldPop为父代种群，pcross为交叉概率
[m,n]=size(OldPop);
r=rand(1,m);
y1=find(r<pcross);
y2=find(r>=pcross);
len=length(y1);
if len>2&mod(len,2)==1%如果用来进行交叉的染色体的条数为奇数，将其调整为偶数
    y2(length(y2)+1)=y1(len);
    y1(len)=[];
end
if length(y1)>=2
   for i=0:2:length(y1)-2
       [NewPop(y1(i+1),:),NewPop(y1(i+2),:)]=EqualCrossOver(OldPop(y1(i+1),:),OldPop(y1(i+2),:));
   end     
end
NewPop(y2,:)=OldPop(y2,:);
