Hi Hoang, Glad to hear the error was resolved. The license options for running on an HPC server are Academic WLS or Educational Institution Site License. The Site License should be managed by a sys...

Hi, Could you clarify what you mean by “good result”? There are several possible candidates: results of variables are not what you want, optimization is slow, etc. Also, can you provide details of ...

Hi Hoang, The program seems to finish to the end without failure on my side. -------------------------------------------------------------------------------                                    Summa...

Hi, You can generate additional academic license. Please see How do I request additional free Academic Named-User licenses?,  How do I obtain a free academic license?. If you are unable to generate...

Hi However, the first feasible solution that the solver returned with / without variable initialization are identical. I mistakenly understood this to be about optimal solutions not first feasibl...

Hi Yifeng, a unknown variable ranging from 0-10, however the initial value is 15 Does this mean that setting x.start = 15 for a variable 0<=x <=10? In such cases, the initial solution is judged t...

Hi Yifeng, Start attribute only affects MIP model. Your model is continuous now. If the variable is an integer as follows: x = model.addVar(vtype="I", lb=0, ub=30, name="x") y = model.addVar(vtype=...

Hi, Unfortunately, Gurobi does not currently provide such a method. Is your goal to have each function take only Model object as arguments and refer to the necessary variable objects in the functio...

Hi, You can pack variables as a List in the function: All_variables = [a, b, c] Then, variables can be unpacked outside the function like this: a, b, c = All_variables Is this the behavior you are ...

Hi, By using SOS-1 constraint, it can be solved as MILP. For example, the constraint that the variables x and y cannot be nonzero at the same time can be written as follows: model.addSOS(GRB.SOS_TY...
