Q of the given QTRS could be proven: (0) QTRS (1) QTRS Reverse [EQUIVALENT, 0 ms] (2) QTRS (3) Strip Symbols Proof [SOUND, 0 ms] (4) QTRS (5) RFCMatchBoundsTRSProof [EQUIVALENT, 1 ms] (6) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(f(x)) -> g(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: f(f(x)) -> f(g(x)) Q is empty. ---------------------------------------- (3) Strip Symbols Proof (SOUND) We were given the following TRS: f(f(x)) -> f(g(x)) By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: f(x) -> g(x) ---------------------------------------- (4) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: f(x) -> g(x) Q is empty. ---------------------------------------- (5) RFCMatchBoundsTRSProof (EQUIVALENT) Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 0. This implies Q-termination of R. The following rules were used to construct the certificate: f(x) -> g(x) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 7, 8 Node 7 is start node and node 8 is final node. Those nodes are connected through the following edges: * 7 to 8 labelled g_1(0)* 8 to 8 labelled #_1(0) ---------------------------------------- (6) YES
