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: a(b(b(a(a(a(a(a(x1)))))))) -> a(a(a(a(a(a(b(b(a(b(b(a(b(b(x1)))))))))))))) 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(a(a(a(a(b(b(a(x1)))))))) -> b(b(a(b(b(a(b(b(a(a(a(a(a(a(x1)))))))))))))) Q is empty. ---------------------------------------- (3) Strip Symbols Proof (SOUND) We were given the following TRS: a(a(a(a(a(b(b(a(x1)))))))) -> b(b(a(b(b(a(b(b(a(a(a(a(a(a(x1)))))))))))))) By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: a(a(a(a(a(b(b(x))))))) -> b(b(a(b(b(a(b(b(a(a(a(a(a(x))))))))))))) ---------------------------------------- (4) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(a(a(a(a(b(b(x))))))) -> b(b(a(b(b(a(b(b(a(a(a(a(a(x))))))))))))) Q is empty. ---------------------------------------- (5) RFCMatchBoundsTRSProof (EQUIVALENT) Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 1. This implies Q-termination of R. The following rules were used to construct the certificate: a(a(a(a(a(b(b(x))))))) -> b(b(a(b(b(a(b(b(a(a(a(a(a(x))))))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 7, 8, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 Node 7 is start node and node 8 is final node. Those nodes are connected through the following edges: * 7 to 35 labelled b_1(0)* 8 to 8 labelled #_1(0)* 35 to 36 labelled b_1(0)* 36 to 37 labelled a_1(0)* 37 to 38 labelled b_1(0)* 38 to 39 labelled b_1(0)* 39 to 40 labelled a_1(0)* 40 to 41 labelled b_1(0)* 41 to 42 labelled b_1(0)* 42 to 43 labelled a_1(0)* 42 to 59 labelled b_1(1)* 43 to 44 labelled a_1(0)* 43 to 59 labelled b_1(1)* 44 to 45 labelled a_1(0)* 44 to 59 labelled b_1(1)* 45 to 46 labelled a_1(0)* 45 to 59 labelled b_1(1)* 46 to 8 labelled a_1(0)* 46 to 59 labelled b_1(1)* 59 to 60 labelled b_1(1)* 60 to 61 labelled a_1(1)* 61 to 62 labelled b_1(1)* 62 to 63 labelled b_1(1)* 63 to 64 labelled a_1(1)* 64 to 65 labelled b_1(1)* 65 to 66 labelled b_1(1)* 66 to 67 labelled a_1(1)* 66 to 59 labelled b_1(1)* 67 to 68 labelled a_1(1)* 67 to 59 labelled b_1(1)* 68 to 69 labelled a_1(1)* 68 to 59 labelled b_1(1)* 69 to 70 labelled a_1(1)* 69 to 59 labelled b_1(1)* 70 to 8 labelled a_1(1)* 70 to 59 labelled b_1(1) ---------------------------------------- (6) YES
