selectchrom.m

用matlab编写的二进制的遗传算法程序.rar

%计算各个体的适应度并采用轮盘赌进行选择
function [selectpop]=selectchrom(FUN,pop,bounds,bits)%采用轮盘赌选择方法
[m,n]=size(pop);
for i=1:m
    fit(i)=feval(FUN(1,:),(b2f(pop(i,:),bounds,bits)));%以函数值为适应度
end
selectprob=fit/sum(fit);%选择概率
prob=cumsum(selectprob);%累计选择概率
sumprob=[0 prob];
for i=1:m
    selectpop(i,:)=pop(length(find(rand>=sumprob)),:);
end
