selection_f.m

遗传算法的实型表示实现

function new_gr=selection_f(initial_gr,n,upbound,downbound)
[result,P]=evalF_f(initial_gr,n,upbound,downbound);
new_sel=rand(1,100);
for i=1:100
    p=P(1);
    for j=1:100
    if(new_sel(i)<p)
        new_gr(i,:)=initial_gr(j,:);
        break;
    else p=p+P(j+1);
    end
    end
 end
