人工免疫进化算法来解决简单字符串识别的问题

function a=repruduction(fit)
global concentration;

[px,py]=size(pop);

[maxvalue,maxposition]=max(fit);
%[minvalue,minposition]=min(fit);
for i=1:px

        pop(i,:)=pop(maxposition,:);
    end
end
%disp(pop);
%pop(minposition:)=pop(maxposition:);%The first time,the best one subtitute the worst one;
%mutation(minposition:);
%copy

%clear
%{maxvalue,maxposition]=max(fit);
