cfitness.m

使用遗传算法求一个多项式函数在区间[0

function [sumfit,maxfit,maxsite,fitness]=cfitness(x,lchrom)
% variable 'x' stands for the b2d values of popular
popsize=length(x);
sumfit=0;
maxfit=0;
maxsite=0;
fitness=zeros(popsize,1);
p=power(2,lchrom)-1;
temp=0;
for m=1:popsize
    temp=31*x(m)/p;         %%%%%%%%% Modify here:area [0 31]
    fitness(m)=temp^2;      %%%%%%%%% Modify here:function f(x)=x^2
    sumfit=sumfit+fitness(m);
    if fitness(m)>maxfit
        maxfit=fitness(m);
        maxsite=temp;
    end
end
