Selects objective index of multi-objectives
Type: int
Default value: 0
Minimum value: 0
Maximum value: 2000000000

When working with multiple objectives, this parameter selects the index of the objective you want to work with. When you modify an attribute associated with multiple objectives (ObjN, ObjNVal, etc.), the ObjNumber parameter will determine which objective is actually affected. The value of this parameter should be less than the value of the NumObj attribute (which captures the number of objectives in the model).
