◆ 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

set	global SCIP settings
newvalue	new value after update
oldvalue	old value, i.e., last reliable value
