Function Documentation

SCIPincludeObjRelax()

SCIP_EXPORT 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

creates the relaxator for the given relaxator object and includes it in SCIP

Parameters

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