YES proof of Transformed_CSR_04_ExConc_Zan97_GM.trs # AProVE Commit ID: c69e44bd14796315568835c1ffa2502984884775 jera 20211004 unpublished Termination w.r.t. Q of the given QTRS could be proven: (0) QTRS (1) QTRS Reverse [EQUIVALENT, 0 ms] (2) QTRS (3) RFCMatchBoundsTRSProof [EQUIVALENT, 0 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a__f(X) -> g(h(f(X))) mark(f(X)) -> a__f(mark(X)) mark(g(X)) -> g(X) mark(h(X)) -> h(mark(X)) a__f(X) -> f(X) Q is empty. ---------------------------------------- (1) QTRS Reverse (EQUIVALENT) We applied the QTRS Reverse Processor [REVERSE]. ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a__f(X) -> f(h(g(X))) f(mark(X)) -> mark(a__f(X)) g(mark(X)) -> g(X) h(mark(X)) -> mark(h(X)) a__f(X) -> f(X) Q is empty. ---------------------------------------- (3) RFCMatchBoundsTRSProof (EQUIVALENT) Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 2. This implies Q-termination of R. The following rules were used to construct the certificate: a__f(X) -> f(h(g(X))) f(mark(X)) -> mark(a__f(X)) g(mark(X)) -> g(X) h(mark(X)) -> mark(h(X)) a__f(X) -> f(X) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 Node 3 is start node and node 4 is final node. Those nodes are connected through the following edges: * 3 to 5 labelled f_1(0)* 3 to 7 labelled mark_1(0)* 3 to 4 labelled g_1(0), f_1(0), g_1(1)* 3 to 10 labelled mark_1(1)* 4 to 4 labelled #_1(0)* 5 to 6 labelled h_1(0)* 6 to 4 labelled g_1(0), g_1(1)* 7 to 4 labelled a__f_1(0), h_1(0), f_1(1)* 7 to 8 labelled f_1(1)* 7 to 11 labelled mark_1(1)* 7 to 10 labelled mark_1(1)* 8 to 9 labelled h_1(1)* 9 to 4 labelled g_1(1)* 10 to 4 labelled a__f_1(1), f_1(2)* 10 to 12 labelled f_1(2)* 10 to 10 labelled mark_1(1)* 11 to 4 labelled h_1(1)* 11 to 11 labelled mark_1(1)* 12 to 13 labelled h_1(2)* 13 to 4 labelled g_1(2), g_1(1) ---------------------------------------- (4) YES
