ObjScale
Objective scaling
| Type: | double | |
|---|---|---|
| Default value: | 0.0 | |
| Minimum value: | -1 | |
| Maximum value: | Infinity |
Divides the model objective by the specified value to avoid numerical
errors that may result from very large objective coefficients. The
default value of 0 decides on the scaling automatically. A value less
than zero uses the maximum coefficient to the specified power as the
scaling (so ObjScale=-0.5 would scale by the square root of
the largest objective coefficient).
Objective scaling can be useful when the objective contains extremely large values, but it can also lead to large dual violations, so it should be used sparingly.
