crossover.m

用matlab自编写的简单遗传算法程序(SGA)

function[newpop]=crossover(pop,pc)
[px,py]=size(pop);newpop=ones(size(pop));
for i=1:2:px-1
    if(rand<pc)
        cpoint=round(rand*py);
        newpop(i,:)=[pop(i,1:cpoint) pop(i+1,cpoint+1:py)];
         newpop(i+1,:)=[pop(i+1,1:cpoint) pop(i,cpoint+1:py)];
    else
        newpop(i,:)=pop(i,:);
        newpop(i+1,:)=pop(i+1,:);
    end
end
