mutation.m

用matlab编写的二进制的遗传算法程序.rar

%变异操作
function [NewPop]=Mutation(OldPop,pmutation)
[m,n]=size(OldPop);
r=rand(1,m);
position=find(r<=pmutation);
len=length(position);
if len>=1
   for i=1:len
       k=unidrnd(n,1,1); %设置变异点数，一般设置1点
       for j=1:length(k)
           if OldPop(position(i),k(j))==1
              OldPop(position(i),k(j))=0;
           else
              OldPop(position(i),k(j))=1;
           end
