Partially modify LHS of a constraint set?
AnsweredI have implemented a column generation algorithm in Gurobi in Python. The most computationally expensive aspect of this algorithm is the reconstruction of the master problem when a column is added ...

Is there a better solution than IntegralityFocus to ensure integrality of variables?
Awaiting user inputI have an MIP model with the following parameter settings: mdl.Params.IntegralityFocus = 1mdl.Params.FeasibilityTol = 1e9 The model sometimes generates variables that are not even close to integer...

Reduce time to prove optimality in a partial MIP algorithm
Awaiting user inputI have a partial MIP algorithm. This algorithm solves a problem iteratively by fixing a portion of variables (decreasing the problem size). An initial solution is always given to the solver in each...

Initialization error: cannot find lgurobi_c++.h
AnsweredI have activated my gurobi license (working with Java). I have written a simple model and am trying to run it via C++ in Clion & Windows OS. I have modified the CMakeList.txt as follows: cmake_mini...
