Hi Jaromił, Thanks for your response. BestBdStop does not work because I cannot guess a good value for it. The below log shows an example termination with a time limit. The gap is 100% because a Be...

Terminate when the first BestBd is found
回答済みI 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 ...

Hey Eli, I love your tsp.py-like vrp.py programming. I think tsp.py should address the word "symmetric" somewhere to make it understandable. In the vrp.py case, you have already defined the model f...

@Yauhen, it was all my bad. My solution was not really feasible. I thought it was a feasible solution and was wrong. Thanks to Daniel, I could verify it.

Getting time values shown in the prints
回答済みIs 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
回答済みI 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...

Hi Tobias, I really appreciate for the response. I have a follow up question though. I was looking at the 'indicator constraints' of Gurobi. Does Gurobi convert indicator constraints (if ..., then....

Gurobi Coding Use for other solvers
回答済みHello, 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 ...
