We want to model our MILP problem with Google OR-Tools in .NET, and solve it using GUROBI (solver may change in the next 1-2 years). However, we couldn't find the correct syntax to call GUROBI.
https://developers.google.com/optimization says it is
Solver solver = Solver.CreateSolver(solver_id);. There are examples of calling GLOP and SCIP, but not for GUROBI (or we failed to find). What we tried listed below, but
Solver solver = Solver.CreateSolver("GUROBI");
Solver solver = Solver.CreateSolver("GUROBI_MIXED_INTEGER_PROGRAMMING");
Question 1: What is the correct way of calling GUROBI?
Question 2: Does OR-Tools allow using callbacks of GUROBI? If so, any source suggestions to refer? https://www.gurobi.com/documentation/9.1/refman/cb_codes.html
