[email=min=@sum(link(i,j)|i #ne# j:distance(i,j)*x(i,j]min=@sum(link(i,j)|i #ne# j:distance(i,j)*x(i,j[/email]));
这行发错了应该是min=@sum(link(i,j)|i #ne# j:distance(i,j)*x(i,j））；

楼上的真有耐心

主程序中的中括号错了吧？

作者: haige 时间: 2009-5-24 10:12
为什么不用matlab写呢？

作者: haige 时间: 2009-5-24 10:14
因为国内的lingo都是演示版的，而且我感觉应该做一个矩阵来处理

看不懂，帮顶~

楼上的真有耐心德国法国

作者: 棉花 时间: 2009-8-30 18:23
我觉得不可能犯少括号这么低级的错误吧！

作者: yj649 时间: 2009-9-6 16:32
就是差括号。

作者: zhula 时间: 2009-9-6 22:02
括号错了，这类问题很容易出现，以后小心
