求MATLAB编遗传算法的程序？

谁帮我用MATLAB编遗传算法的程序？告诉我怎么编啊？最好是IEEE14节点的潮流计算和遗传算法程序一起，感激不尽！

Answer 1

figure(1);
fplot('variable.*sin(10*pi*variable)+2.0',[-1,2]);
NIND=40;
MAXGEN=25;
PRECI=20;
GGAP=0.9;
trace=zeros(2,MAXGEN);
FieldD=[20;-1;2;1;0;1;1];
Chrom=CRTBP(NIND,PRECI);
gen=0;
variable=BS2RV(Chrom,FieldD);
ObjV=variable.*sin(10*pi*variable)+2.0;
while gen<MAXGEN,
FitnV=ranking(-ObjV);
SelCh=SELECT('SUS',Chrom,FitnV,GGAP);
SelCh=RECOMBIN('XOVSP',SelCh,0.7)
SelCh=MUT(SelCh);
variable=BS2RV(SelCh,FieldD);
ObjVSel=variable.*sin(10*pi*variable)+2.0;
[Chrom,ObjV]=REINS(Chrom,SelCh,1,1,ObjV,ObjVSel);
gen=gen+1;
[Y,I]=max(ObjV),hold on;
plot(variable(I),Y,'bo');
trace(1,gen)=max(ObjV);
trace(2,gen)=sum(ObjV)/length(ObjV);
end
variable=BS2RV(Chrom,FieldD);
hold on;
grid;
plot(variable',ObjV','b*');
figure(2);
plot(trace(1,:)');
hold on;
plot(trace(2,:)','-.');
grid;
看看这个能用得上么

matlab里使用遗传算法只有两个函数，分别是gaoptimset和ga函数，在命令行输入 doc gaoptimset或者doc ga可以查看他们的用法。
