Function Documentation

SCIP_RETCODE SCIPincludeObjRelax	(	SCIP *	scip,
		scip::ObjRelax *	objrelax,
		SCIP_Bool	deleteobject
	)

creates the relaxator for the given relaxator 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) ); ... MyRelax* myrelax = new MyRelax(...); SCIP_CALL( SCIPincludeObjRelax(scip, &myrelax, FALSE) ); ... SCIP_CALL( SCIPfree(&scip) ); delete myrelax; // delete relax AFTER SCIPfree() !
2. The object pointer is passed to SCIP and deleted by SCIP in the SCIPfree() call: SCIP_CALL( SCIPcreate(&scip) ); ... SCIP_CALL( SCIPincludeObjRelax(scip, new MyRelax(...), TRUE) ); ... SCIP_CALL( SCIPfree(&scip) ); // destructor of MyRelax is called here

Parameters

scip	SCIP data structure
objrelax	relaxator object
deleteobject	should the relaxator object be deleted when relaxator is freed?
