Type: double
Modifiable: Yes

When the model has multiple objectives, this attribute is used to query or modify objective coefficients for objective <span>$</span>n<span>$</span>. You set <span>$</span>n<span>$</span> using the ObjNumber parameter. Note that when ObjNumber is equal to 0, ObjN is equivalent to Obj.

The number of objectives in the model can be queried (or modified) using the NumObj attribute.

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 attributes, refer to our Attribute Examples.
