qmutation.asv

一种带量子门的改进的遗传算法matlab源程序。

function ret=Qmutation(pmutation,individuals.chrom,sizepop,lenchrom)


for i=1:sizepop
    
    % select child at random
    pick=rand;
    while pick==0
        pick=rand;
    end
    index=ceil(pick*sizepop);
    pick=rand;
    if pick>pmutation
      continue;
    end
    % mutation position
    pick=rand;
    while pick==0
         pick=rand;
    end
    pos=ceil(pick*sum(lenchrom));
    v=bitget(chrom(index),pos); 
    v=~v;
    chrom(index)=bitset(chrom(index),pos,v);
end
            
ret=chrom;
