ObjNumber
Selects objective index of multi-objectives
| Type: | int | |
|---|---|---|
| Default value: | 0 | |
| Minimum value: | 0 | |
| Maximum value: | MAXINT |
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
(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).
Please refer to the discussion of Multiple Objectives for more information on the use of alternative objectives.
One important note about integer-valued parameters: while the maximum
value that can be stored in a signed integer is 
, we use a
MAXINT value of 2,000,000,000. Attempting to set an integer
parameter to a value larger than this maximum will produce an error.
For examples of how to query or modify parameter values from our different APIs, refer to our Parameter Examples.
