    ◆ SCIPincludeObjRelax()

    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
    scipSCIP data structure
    objrelaxrelaxator object
    deleteobjectshould the relaxator object be deleted when relaxator is freed?
