XKTR_PARAM_OBJRANGE
| 
     Description
     | 
     Specifies the extreme limits of the objective function for purposes of determining unboundedness.
     | 
| 
     Type
     | 
     Double
     | 
| 
     Default value
     | 
     1.0e20
     | 
| 
     Note
     | 
     If the magnitude of the objective function becomes greater than objrange for a feasible iterate, then the problem is determined to be unbounded and KNITRO proceeds no further.
