# GLOBALBOUNDINGBOX

Description | If a nonlinear problem cannot be solved due to appearing unbounded, it can automatically be regularized by the application of a bounding box on the variables. If this control is set to a negative value, in a second solving attempt all original variables will be bounded by the absolute value of this control. If set to a positive value, there will be a third solving attempt afterwards, if necessary, in which also all auxiliary variables are bounded by this value.
Type | Double
Topic area | Global
Values |
0 | Disabled. Problem will return unbounded.
n<0 | Enabled. Apply lower and upper bounds of this magnitude to all original variables if initial LP is unbounded.
n>0 | Enabled. Apply lower and upper bounds of this magnitude to all original and auxiliary variables if initial LP and first regularization are unbounded.
Default value | 1.0E+06
Affects routines | XPRSoptimize ( OPTIMIZE).
