    m.Runtime

    回答済み

    Hi, I have a question and I appreciate your help. When I ask gurobi to print the Runtime after solving the model, the run time it shows is much less than the actual time it takes. Then, I put a tim...

    Hi Matthias,  Thank you for your response. I have shared the log file below. The first model is the one I run to get the optimal solution, and the second model is the one that I run with the optima...

    MIP start is the optimal solution and yet I receive "MIP start did not produce a new incumbent solution"

    Hi, I am trying to solve a Maximization MIP problem with gurobi. It takes ages to solve the problem. I tried different warm-up starts, and I always receive "MIP start did not produce a new incumben...

    Hi Silke, thank you for your response. 2: isn't it the case that if you find a lower upper bound for your maximization problem, it will speed up the process of finding an optimal solution? 3: I hav...

    MIP start is an infeasible solution

    回答済み

    Hello, I am trying to solve my model using Gurobi in python. My problem is a Maximization problem. From solving another model with the same variables, I can find a good upper bound for my current p...

    Hi Eli, thank you for your quick response. Oh, I thought that MIPGapAbs is |MIPGap|. So, I will run the model with MIPGap and let you know about the results. I have a quick question about these par...

    Gurobi Parameters

    回答済み

    Hello,  I am running an optimization model for a big case study. I applied three below parameters to increase the solving speed of the model. However, the stopping method MIPGapAbs doesn't work. In...
