Hi, Once the model is solved, you can query the Status attribute to check the status of the model. (You can find all of the status codes here.) For example, in Python, you could do this: if model.S...

It should be "gp.GRB.BINARY". Alternatively, people also like to do: from gurobipy import GRB Then you can simply use "GRB.BINARY".

I added another (less general) approach to your other post here.

Hi, You could add some auxiliary binary variables; some that are 1 if and only if X > 0 and some others that are 1 if and only if X < 1. B0 = m.addVars(M, N, vtype=GRB.BINARY)B1 = m.addVars(M, N, v...

Hi David, The angles should always be in radians. Best regardsSilke

Hi, What are the types of c and s? Are they scalars or decision variables? If they are decision variables: One cannot use a model's decision variables in if-conditions while building the model (sin...

Hi, Thanks for posting your log. The model is not extremely big and the numerics seems all right. From the log, you can see that presolve and the root relaxation are quite fast, but then Gurobi str...

Sometimes models are so hard that Gurobi cannot find any solution within 1 hour. How big is the model and where is Gurobi stuck? Could you post your log here?

We have assisted you in a support ticket, but I'll also post the gist of the answer here to help other users: We have dropped support for unencrypted HTTP connections to the license server for secu...

Hi, In Gurobi, variables don't have a default value. If there are multiple optimal solutions (for example by choosing different values for variables that do not participate in any constraint or the...
