Gurobi Optimizer: determining feasibility without optimizing the model

Question

In Gurobi, is it possible to see if a group of constraints and variables are feasible without actually optimizing the problem? It seems if the objective is a constant, Gurobi still does a lot of heavy computation to find an optimal solution, which I don't need!

Answer 1

Sorry. Except for very easy infeasibilities that can be detected in the presolver, Gurobi may have to do lots of work to prove whether the model is feasible or infeasible. No silver bullets here.
