Q of the given QTRS could be disproven: (0) QTRS (1) NonTerminationProof [COMPLETE, 0 ms] (2) NO ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: 0(q0(0(x1))) -> 0(0(q0(x1))) 0(q0(h(x1))) -> 0(0(q0(h(x1)))) 0(q0(1(x1))) -> 0(1(q0(x1))) 1(q0(0(x1))) -> 0(0(q1(x1))) 1(q0(h(x1))) -> 0(0(q1(h(x1)))) 1(q0(1(x1))) -> 0(1(q1(x1))) 1(q1(0(x1))) -> 1(0(q1(x1))) 1(q1(h(x1))) -> 1(0(q1(h(x1)))) 1(q1(1(x1))) -> 1(1(q1(x1))) 0(q1(0(x1))) -> 0(0(q2(x1))) 0(q1(h(x1))) -> 0(0(q2(h(x1)))) 0(q1(1(x1))) -> 0(1(q2(x1))) 1(q2(0(x1))) -> 1(0(q2(x1))) 1(q2(h(x1))) -> 1(0(q2(h(x1)))) 1(q2(1(x1))) -> 1(1(q2(x1))) 0(q2(x1)) -> q3(1(x1)) 1(q3(x1)) -> q3(1(x1)) 0(q3(x1)) -> q4(0(x1)) 1(q4(x1)) -> q4(1(x1)) 0(q4(0(x1))) -> 1(0(q5(x1))) 0(q4(h(x1))) -> 1(0(q5(h(x1)))) 0(q4(1(x1))) -> 1(1(q5(x1))) 1(q5(0(x1))) -> 0(0(q1(x1))) 1(q5(h(x1))) -> 0(0(q1(h(x1)))) 1(q5(1(x1))) -> 0(1(q1(x1))) h(q0(x1)) -> h(0(q0(x1))) h(q1(x1)) -> h(0(q1(x1))) h(q2(x1)) -> h(0(q2(x1))) h(q3(x1)) -> h(0(q3(x1))) h(q4(x1)) -> h(0(q4(x1))) h(q5(x1)) -> h(0(q5(x1))) Q is empty. ---------------------------------------- (1) NonTerminationProof (COMPLETE) We used the non-termination processor [OPPELT08] to show that the SRS problem is infinite. Found the self-embedding DerivationStructure: "0 q0 h -> 0 0 q0 h" 0 q0 h -> 0 0 q0 h by original rule (OC 1) ---------------------------------------- (2) NO
