popmerge41.m

用4个种群来优化函数

function [individuals5,bestfitness,bestchrom] = PopMerge41(individuals1,individuals2,individuals3,individuals4,sizepop,lenchrom,fcode,bound,bestfitness,bestchrom)
%从群体individual1,individual2,individual3,individual4中选出3个最佳个体构成数组individual4

    individuals5.chrom(i,:) = individuals1.chrom(pos,:);

%计算individual5中的个体适应度
for i = 1:sizepop
    x=Decode(lenchrom,bound,individuals5.chrom(i,:),fcode);%解码（binary和grey的解码结果为一个二进制串，float的解码结果为一个实数向量）
    %individuals.fitness(i)=AimFunc(x,heli,id_data,0);
    individuals5.fitness(i)=Aimfunc(x);   %染色体的适应度
end

 [bestfitness,bestindex]=min(individuals5.fitness);
    bestchrom=individuals5.chrom(bestindex,:);
    avgfitness=sum(individuals5.fitness)/sizepop;
    trace5=[avgfitness bestfitness];
