    ◆ SCIPincludeObjHeur()

    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
    scipSCIP data structure
    objheurprimal heuristic object
    deleteobjectshould the primal heuristic object be deleted when heuristic is freed?
