I have a LP/MPS file like this:

我有这样一个LP/MPS文件:


Maximize
3x + 2y

Subject To
Constraint1: x + 2y <= 5
Constraint2: 2x - y >= 3

Bounds
0 <= x <= 10
y >= 0

General
x, y

End

Can I read it in pulp or I have to read by myself?
I've tried to read it by myself, and it's very complicated. I also searched on the internet for how to read an LP/MPS file, but I didn't find any instructions.
Thanks

我可以看纸质书,还是自己读?我试着自己读它,它非常复杂。我还在网上搜索了如何阅读LP/MPS文件,但没有找到任何说明。谢谢

You'll have to rewrite the problem in python. See pulp examples. MPS is an old format (punch card old), you probably don't want to go there.

您必须用python语言重写这个问题。请参阅纸浆示例。MPS是一种旧的格式(穿孔卡片旧),你可能不想去那里。

I don't get what you mean, I want to read that file to pulp and solve it, your example is write the problem into a file, right?

我不明白你的意思,我想把那个文件读成纸浆,然后解决它,你的例子是把问题写到一个文件里,对吗?

You cannot read your file in. You must rewrite the problem in the form shown in the pulp examples.

您不能读取您的文件。你必须用纸浆例子中所示的形式重写这道题。

oh, after rewrite can I read that file?

哦,重写后我可以读那个文件吗?
