The type of refinement used, if any.
A int specifying the type of refinement used.
The possible settings are:
| Value | Action |
|---|---|
| 0 | No refinement. Always compute dual. This is the default. |
| 1 | Iterative refinement. |
| 2 | Use extended refinement. Iterate until no more progress. |
If refinement is used, the coefficient matrices and other data are saved at the beginning of the computation. When finished this data together with the solution obtained is checked for consistency. If the discrepancy is too large, the solution process is restarted using the problem data just after processing the equalities, but with the final x values and final active set.
