lingo程序
哪位高手帮忙看看一下程序错在哪里，为什么求不出结果呢？model:
sets:
police/1..307/:p;
control/1..307/:c;
link(police,control):a;
endsets
data:
n=307;fugailv=0.9;
enddata
min=@sum(police:p(i));
@sum(control:c(i))>=fugailv*n;
@for(control:1-c(i)=@prod(police(j):(1-a(j,i))*p(j)););
@for(police:@bin(p(i)));
@for(control:@bin(c(i)));
@for(link:@for(link:@bin(a(i,j))););
end
