问题描述
我有一个基本问题。我在C ++中使用Cplex,并尝试通过它来实现优化程序。但是,我有一个基本问题。
I have an essential problem. I use Cplex in C++ and I try to implement my optimization programs by it; however, I have an essential problem.
我想找到我的程序的对偶。如何在Cplex for C ++中找到可以做到这一点的构造?
I want to find dual of my program. How can I find some constructs in Cplex for C++ that do it?
推荐答案
我不确定这是否是您要的,但是(引用文档):
I'm not entirely sure if this is what you're asking for, but the presolve dual setting (quoting the documentation):
可以使用C ++ API进行设置,如下所示:
With the C++ API, this can be set, like so:
cplex.setParam(IloCplex::Param::Preprocessing::Dual, 1);
与:
另一方面,如果您想在求解模型后查询对偶值,则可以使用方法。
If, on the other hand, you want to query dual values after solving a model, you can use the getDuals method.
