Function Documentation

SCIPincludeObjBenderscut()

SCIP_RETCODE SCIPincludeObjBenderscut	(	SCIP *	scip,
		scip::ObjBenders *	objbenders,
		scip::ObjBenderscut *	objbenderscut,
		SCIP_Bool	deleteobject
	)

creates the Benders' decomposition cut for the given Benders' decomposition cut object and includes it in SCIP

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

1. The user is responsible for deleting the object: SCIP_CALL( SCIPcreate(&scip) ); ... MyBenderscut* mybenderscut = new MyBenderscut(...); SCIP_CALL( SCIPincludeObjBenderscut(scip, benders, &mybenderscut, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete mybenderscut; // delete benderscut AFTER SCIPfree() !
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjBenderscut(scip, benders, new MyBenderscut(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyBenderscut is called here

creates the Benders' decomposition cut for the given Benders' decomposition cut object and includes it in SCIP

Parameters

scip	SCIP data structure
objbenders	Benders' decomposition object
objbenderscut	Benders' decomposition cut object
deleteobject	should the Benders' decomposition cut object be deleted when benderscut is freed?
