NumObj

Type:	int
Modifiable:	Yes

Number of objectives in the model. If you modify this attribute, it will change the number of objectives in the model. Decreasing it will discard existing objectives. Increasing it will create new objectives (initialized to 0). Setting it to 0 will create a model with no objective (i.e., a feasibility model).

You can use theObjNumberparameter, in conjunction with multi-objective attributes (ObjN,ObjNName, etc.), to query or modify attributes for different objectives. The value ofObjNumbershould always be less thanNumObj.

Please refer to the discussion ofMultiple Objectivesfor more information on the use of alternative objectives.
