Does Gurobi have issue with self assignment of an expression?
AnsweredI noticed something very strange with my model. I had a line of code e.g., A_LinExp = A_LinExp + B_LinExp And then I used the A_LinExp in the Objective function. However, after finding the soluti...

MIQP Model taking forever to compute
AnsweredHello! I am trying to run an MIQP model with indicator constraints and it is taking forever to compute. I have already let it run for 4 days non-stop and still could not get it solved. Please find ...

Not able to retrieve suboptimal solutions. Gurobi does not return the ones it identifies during the solution.
AnsweredI tried retrieving the variable values for suboptimal solutions of my MIQP problem (with bilinear terms in obj) using the SolNumber parameter. During the solution process Gurobi prints that it was ...

GRB.MAXIMISE identifies lower objective function values than GRB.MINIMIZE. How can this be avoided?
OngoingHello, I have a sufficiently big optimization problem with many bilinear terms in the objective function (MIQP). The issue that I face is that when I use GRB.MINIMIZE, Gurobi only identifies a sing...

Is it possible to change when (the gap %level) Gurobi starts focusing on finding feasible solutions instead finding a lower lower bound?
AnsweredI am trying to solve a nonconvex MIQP. I see that I was very close to the final solution within about 3000 seconds but gurobi still kept on focusing on finding a lower lower bound instead of trying...

Extra variables being generate during solution process and IntInf has way higher value than the number of integer constraints I have in the model.
AnsweredI have a MIQP model with 1074 continuous and 1072 binary variables. I had already successfully tested the model with 43 continuous and 40 binary variables before. But now in the scaled up model, I ...
