crossover1.asv

请大家看一看, 我编的这个用遗传算法求 f(x)=xsin(10pi*x)+2.0 x为-1到2区间的值

%遗传算法中交叉部分程序;
%采用单点交叉的方式,随机选中其中的一位,作为交叉点.
function newpop=crossover1(oldpop,pc)
[px,py]=size(oldpop); 
crosssite=round(rand*py);
 for i=1:2:px
if rand<pc
      newpop(i,:)=[oldpop(i,1:crosssite) oldpop(i+1,crosssite+1:py)];
      newpop(i+1,:)=[oldpop(i+1,1:crosssite) oldpop(i,crosssite+1:py)];
  else
      newpop(i,:)=oldpop(i,:);
      newpop(i+1,:)=oldpop(i+1,:); 
end
end
