GRBModel.SingleScenarioModel()

Capture a single scenario from a multi-scenario model. Use the ScenarioNumber parameter to indicate which scenario to capture.

The model on which this method is invoked must be a multi-scenario model, and the result will be a single-scenario model.

GRBModel SingleScenarioModel ( )

    Return value:

    Model for a single scenario.
