◆ SCIPchgRelaxfeastol()
| SCIP_EXPORT SCIP_Real SCIPchgRelaxfeastol | ( | SCIP * | scip, |
| SCIP_Real | relaxfeastol | ||
| ) |
sets the primal feasibility tolerance of relaxations
This tolerance value is used by the SCIP core and plugins to tighten then feasibility tolerance on relaxations (especially the LP relaxation) during a solve. It is set to SCIP_INVALID initially, which means that only the feasibility tolerance of the particular relaxation is taken into account. If set to a valid value, however, then this value should be used to reduce the primal feasibility tolerance of a relaxation (thus, use the minimum of relaxfeastol and the relaxations primal feastol).
- Precondition
- The value of relaxfeastol is reset to SCIP_INVALID when initializing the solve (INITSOL). Therefore, this method can only be called in one of the following stages of the SCIP solving process:
- Returns
- previous value of relaxfeastol
- Parameters

◆ SCIPisUpdateUnreliable()
| SCIP_EXPORT SCIP_Bool SCIPisUpdateUnreliable | ( | SCIP * | scip, |
| SCIP_Real | newvalue, | ||
| SCIP_Real | oldvalue | ||
| ) |
Checks, if an iteratively updated value is reliable or should be recomputed from scratch. This is useful, if the value, e.g., the activity of a linear constraint or the pseudo objective value, gets a high absolute value during the optimization process which is later reduced significantly. In this case, the last digits were canceled out when increasing the value and are random after decreasing it. We do not consider the cancellations which can occur during increasing the absolute value because they just cannot be expressed using fixed precision floating point arithmetic, anymore. In order to get more reliable values, the idea is to always store the last reliable value, where increasing the absolute of the value is viewed as preserving reliability. Then, after each update, the new absolute value can be compared against the last reliable one with this method, checking whether it was decreased by a factor of at least "lp/recompfac" and should be recomputed.
- Parameters
-
scip SCIP data structure newvalue new value after update oldvalue old value, i.e., last reliable value
