When working with multiple objectives, this parameter selects the
index of the objective you want to work with. When you query or modify an
attribute associated with multiple objectives
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).
Please refer to the discussion of Multiple Objectives for more information on the use of alternative objectives.
For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
