求大神解释lingo中简答代码的意思

代码如下，求解答，谢谢
min = @ sum(roads:w*x);
@ for(cities(i)|i#ne#1#and#i#ne#n:
@ sum(roads(i,j):x(i,j))=@ sum(roads(j,i):x(j,i)));
@ sum(roads(i,j)|i#eq#1:x(i,j))=1;
@ sum(roads(i,j)|j#eq#n:x(i,j))=1;

Answer 1

@for(row(i):@sum(col(j):a(i,j)*x(j))>=b(i));
这句是满足需求
@for(col:@bin(x));
@sum(col:x)=4; 这两句是选择4个点
min=@sum(juli(i,j):x(i)*x(j)*c(i,j));
