Q of the given QTRS could be disproven: (0) QTRS (1) NonTerminationProof [COMPLETE, 273 ms] (2) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(l(x1)) -> l(a(x1)) r(a(x1)) -> a(r(x1)) b(l(x1)) -> b(a(r(x1))) r(b(x1)) -> l(b(x1)) Q is empty. ---------------------------------------- (1) NonTerminationProof (COMPLETE) We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
