Q of the given QTRS could be disproven: (0) QTRS (1) NonTerminationProof [COMPLETE, 1402 ms] (2) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(L(x)) -> L(a(x)) R(a(x)) -> a(R(x)) a(L(L(x))) -> a(L(R(x))) R(R(a(x))) -> L(a(R(a(x)))) Q is empty. ---------------------------------------- (1) NonTerminationProof (COMPLETE) We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
