    3. Lagrangian Relaxation bound greater than optimal solution

    Hi, I'm trying to minimize an MIP model employing a Lagrangian relaxation approach. However, I've encountered an issue where, in certain instances, the lower bound (resulting from the Lagra...

    Hi,   I'm trying to solve an MIP model to optimality using Gurobi. The thing is that once I increase the power of one of my decision variables, for instance to 4, the model gets infeasible. I did n...
