Q of the given QTRS could be disproven: (0) QTRS (1) NonTerminationProof [COMPLETE, 2511 ms] (2) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: c(c(x1)) -> b(b(x1)) a(b(x1)) -> a(c(b(x1))) b(a(x1)) -> b(b(x1)) b(c(x1)) -> c(a(a(x1))) Q is empty. ---------------------------------------- (1) NonTerminationProof (COMPLETE) We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite.
