Adding and removing Scenarios in multiscenario setting
回答済みHi,
I noticed that in the multi-scenario feature of Gurobi, there is no option of removing scenarios.
This is problematic when we use a model iteratively instead of creating and deleting a model in each iteration. For instance, if we define a scenario in an iteration by changing the right-hand side of constraint 1. In the next iteration, if we want to change the base scenario and then define scenario 1 by changing the right-hand side of constraint 2. Scenario one would have the information from the previous iteration ( change on the right-hand side of constraint 1 ) and the change on the right-hand side of constraint 2!
I would highly appreciate it if you help with that. Thank you!

In your example, you can remove the RHS change of constraint 1 in scenario 1 by setting the constraint's ScenNRHS attribute to \( \texttt{GRB_UNDEFINED} \) or \( \texttt{GRB.UNDEFINED} \) (depending on your API). This way, scenario 1 would only include the change to the RHS of constraint 2. Does this work for you?
