Function Documentation

SCIP_RETCODE SCIPincludeObjHeur	(	SCIP *	scip,
		scip::ObjHeur *	objheur,
		SCIP_Bool	deleteobject
	)

creates the primal heuristic for the given primal heuristic object and includes it in SCIP

The method should be called in one of the following ways:

1. The user is resposible of deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyHeur* myheur = new MyHeur(...); SCIP_CALL( SCIPincludeObjHeur(scip, &myheur, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete myheur; // delete heur AFTER SCIPfree() !
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjHeur(scip, new MyHeur(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyHeur is called here

creates the primal heuristic for the given primal heuristic object and includes it in SCIP

Parameters

scip	SCIP data structure
objheur	primal heuristic object
deleteobject	should the primal heuristic object be deleted when heuristic is freed?
