Terminate when the first BestBd is found
AnsweredI am trying to find the optimality gap of a solution (retrieved from a heuristic). Briefly, my procedure is: 1) find a heuristic solution, 2) feed the solution into Gurobipy MIP formulation as a st...

Two-type VRP
I am trying to formulate a VRP for two types of vehicles and a single depot. V1 represents, say EVs, and V2 represents gas-fueled vehicles. V1-type vehicles consume less fuel/energy in the first M ...

Getting time values shown in the prints
AnsweredIs there any way in Python to record the time MIP start produces a solution. For example, how can I get 0.11s printed? Also, is there any way to get the time values for root relaxation and presolve...

MIP start did not produce a new incumbent solution
AnsweredI have seen this title has been used before (in Gurobi Google Groups) but I could not find a satisfying response for my specific issue. I am trying to solve a MIP with two sets of variables: x[v] a...

Gurobi Coding Use for other solvers
AnsweredHello, I wonder if we can run models constructed by Gurobi's coding convention (in Python) using other open source solvers, e.g., GLPK? More clearly, assume I have a MIP model programmed and ready ...
