# BARREGULARIZE

Description | This bit-vector control (see Section Bit-vector controls) determines how the barrier algorithm applies regularization on the KKT system.
Type | Integer
Topic areas | Barrier, Bit-vector
Values |
Bit | Meaning
0 | Standard regularization is turned on/off.
1 | Reduced regularization is turned on/off. This option reduces the perturbation effect of the standard regularization.
2 | Forces to keep dependent rows in the KKT system.
3 | Forces to preserve degenerate rows in the KKT system.
4 | Restrict regularization to infeasible iterates.
5 | Disable iterative regularizations.
6 | Apply iterative regularization more often.
Default value | -1
Note | The parameter is a bit set but value -1 (the default value) is treated in a special way: if the parameter is set to -1 then the solver will automatically select the bits it deems most useful.
Affects routines | XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE), XPRSminim ( MINIM), XPRSmaxim ( MAXIM).
