Q of the given QTRS could be proven: (0) QTRS (1) RFCMatchBoundsTRSProof [EQUIVALENT, 19 ms] (2) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: g(c(x1)) -> g(f(c(x1))) g(f(c(x1))) -> g(f(f(c(x1)))) g(g(x1)) -> g(f(g(x1))) f(f(g(x1))) -> g(f(x1)) Q is empty. ---------------------------------------- (1) RFCMatchBoundsTRSProof (EQUIVALENT) Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 3. This implies Q-termination of R. The following rules were used to construct the certificate: g(c(x1)) -> g(f(c(x1))) g(f(c(x1))) -> g(f(f(c(x1)))) g(g(x1)) -> g(f(g(x1))) f(f(g(x1))) -> g(f(x1)) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 30, 31, 38, 39 Node 1 is start node and node 2 is final node. Those nodes are connected through the following edges: * 1 to 3 labelled g_1(0)* 1 to 5 labelled g_1(0)* 1 to 11 labelled g_1(1)* 1 to 9 labelled g_1(1)* 1 to 14 labelled g_1(2)* 2 to 2 labelled #_1(0)* 3 to 4 labelled f_1(0)* 3 to 2 labelled f_1(0)* 3 to 8 labelled g_1(1)* 3 to 11 labelled g_1(1)* 3 to 30 labelled g_1(2)* 4 to 2 labelled c_1(0), g_1(0)* 4 to 9 labelled g_1(1)* 4 to 11 labelled g_1(1)* 4 to 14 labelled g_1(2)* 5 to 6 labelled f_1(0)* 6 to 7 labelled f_1(0)* 7 to 2 labelled c_1(0)* 8 to 2 labelled f_1(1)* 8 to 8 labelled g_1(1)* 8 to 30 labelled g_1(2)* 8 to 11 labelled g_1(1)* 9 to 10 labelled f_1(1)* 10 to 2 labelled c_1(1), g_1(1)* 10 to 9 labelled g_1(1)* 10 to 11 labelled g_1(1)* 10 to 14 labelled g_1(2)* 11 to 12 labelled f_1(1)* 12 to 13 labelled f_1(1)* 12 to 8 labelled g_1(1)* 12 to 30 labelled g_1(2), g_1(1)* 12 to 11 labelled g_1(1)* 13 to 2 labelled c_1(1)* 14 to 15 labelled f_1(2)* 15 to 16 labelled f_1(2)* 16 to 2 labelled c_1(2)* 30 to 31 labelled f_1(2)* 31 to 8 labelled g_1(2)* 31 to 30 labelled g_1(2)* 31 to 38 labelled g_1(3)* 31 to 11 labelled g_1(2), g_1(1)* 38 to 39 labelled f_1(3)* 39 to 30 labelled g_1(3) ---------------------------------------- (2) YES
