Hey Gurobi team,

I have a question about something I noticed and I would like to confirm my theory and get more info about it.

It is the following: I added some vars and I have some restrictions associated with them, however, those restrictions are indicator constraints. When I look at the objective function, I see those variables there (so far as I have read, all variables related to any constraint are shown there multiplied by zero) but I guess I should not see them there since they are linked and restricted via the addConstr() method.

My question is: are those variables, whose unique usage in the model is done with indicator constraints, still displayed in the objective function?

Here are some screenshots for clarification:

Objective function:

Constraint:

Any clarification is more than appreciated!

 

Thanks.

Sebastian
