ObjNRelTol
| Type: | double |
|---|---|
| Modifiable: | Yes |
This attribute is used to set the allowable degradation for objective
when doing hierarchical multi-objective optimization. You set
using the ObjNumber parameter.
Hierarchical multi-objective optimization will optimize for the
different objectives in the model one at a time, in priority order.
If it achieves objective value 
when it optimizes for this objective,
then subsequent steps are allowed to degrade this value by at
most ObjNRelTol*
.
The number of objectives in the model can be queried (or modified) using the NumObj attribute.
For examples of how to query or modify attributes, refer to our Attribute Examples.
