The gurobi can not find the optimization solution
Awaiting user inputNow，i am using the Gurobi 9.5. For my model, it seems gurobi does not find the optimization solution.
some log:
Found heuristic solution: objective 1620295.6729
Root relaxation: objective 1.619696e+06, 121 iterations, 0.00 seconds (0.00 work units)

Cutting planes:

Thread count was 8 (of 8 available processors)

Best objective 1.620295672857e+06, best bound 1.620295672857e+06, gap 0.0000%
I will upload my model file. Could you help me take a look?
Thanks.

Hi David,
According to the log snippet you posted, Gurobi does find the optimal solution. Indeed, the final gap is 0% meaning that Gurobi found the true optimal solution to this problem. Could you elaborate why you think that Gurobi does not find any solution?
Best regards,
