copies plugins from sourcescip to targetscip; in case that a constraint handler which does not need constraints cannot be copied, valid will return FALSE. All plugins can declare that, if their copy process failed, the copied SCIP instance might not represent the same problem semantics as the original. Note that in this case dual reductions might be invalid.

◆ SCIPsetIsUpdateUnreliable()

SCIP_Bool SCIPsetIsUpdateUnreliable ( SCIP_SET set,
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 dot 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. The idea to get more reliable values 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
setglobal SCIP settings
newvaluenew value after update
oldvalueold value, i.e., last reliable value
