How to know whether a model is feasible

Question

I am using C# api. Given a gurobi model

GRBModel model = new GRBModel(env);

after populating constraint, giving objective function, and doing

model.Optimize();

is there a way to determine whether the model is feasible?

Answer 1

You need to check the optimization status code after solving the model. In most cases, you simply need to test that the status is OPTIMAL. For an example, see mip2_cs.cs in the examples\c# subdirectory.
