SCIP_RETCODE SCIPsetCopyPlugins	(	SCIP_SET *	sourceset,
		SCIP_SET *	targetset,
		SCIP_Bool	copyreaders,
		SCIP_Bool	copypricers,
		SCIP_Bool	copyconshdlrs,
		SCIP_Bool	copyconflicthdlrs,
		SCIP_Bool	copypresolvers,
		SCIP_Bool	copyrelaxators,

		SCIP_Bool	copybranchrules,
		SCIP_Bool	copydisplays,
		SCIP_Bool	copydialogs,
		SCIP_Bool	copynlpis,
		SCIP_Bool *	allvalid
	)

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.

Parameters

sourceset	source SCIP_SET data structure
targetset	target SCIP_SET data structure
copyreaders	should the file readers be copied
copypricers	should the variable pricers be copied
copyconshdlrs	should the constraint handlers be copied
copyconflicthdlrs	should the conflict handlers be copied
copypresolvers	should the presolvers be copied
copyrelaxators	should the relaxators be copied
copyseparators	should the separators be copied
copypropagators	should the propagators be copied
copyheuristics	should the heuristics be copied
copyeventhdlrs	should the event handlers be copied
copynodeselectors	should the node selectors be copied
copybranchrules	should the branchrules be copied
copydisplays	should the display columns be copied
copydialogs	should the dialogs be copied
copynlpis	should the NLP interfaces be copied
allvalid	pointer to store whether all plugins were validly copied

SCIP_Bool SCIPsetIsUpdateUnreliable	(	SCIP_SET *	set,
		SCIP_Real	newvalue,

	)

Checks, if an iterativly 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 cancelled 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.
