Q of the given QTRS could be disproven: (0) QTRS (1) NonTerminationProof [COMPLETE, 91 ms] (2) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: R(b(x1)) -> b(R(x1)) R(c(x1)) -> L(c(x1)) b(L(x1)) -> L(b(x1)) a(L(x1)) -> a(b(R(x1))) Q is empty. ---------------------------------------- (1) NonTerminationProof (COMPLETE) We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
