Q of the given QTRS could be proven: (0) QTRS (1) Strip Symbols Proof [SOUND, 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: b(a(a(b(b(a(a(a(a(b(x1)))))))))) -> a(a(b(b(a(a(a(a(b(b(a(a(b(x1))))))))))))) Q is empty. ---------------------------------------- (1) Strip Symbols Proof (SOUND) We were given the following TRS: b(a(a(b(b(a(a(a(a(b(x1)))))))))) -> a(a(b(b(a(a(a(a(b(b(a(a(b(x1))))))))))))) By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: b(a(a(b(b(a(a(a(a(x))))))))) -> a(a(b(b(a(a(a(a(b(b(a(a(x)))))))))))) ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: b(a(a(b(b(a(a(a(a(x))))))))) -> a(a(b(b(a(a(a(a(b(b(a(a(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: b(a(a(b(b(a(a(a(a(x))))))))) -> a(a(b(b(a(a(a(a(b(b(a(a(x)))))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61 Node 2 is start node and node 5 is final node. Those nodes are connected through the following edges: * 2 to 6 labelled a_1(0)* 5 to 5 labelled #_1(0)* 6 to 7 labelled a_1(0)* 7 to 8 labelled b_1(0)* 8 to 9 labelled b_1(0)* 9 to 10 labelled a_1(0)* 10 to 11 labelled a_1(0)* 11 to 12 labelled a_1(0)* 12 to 13 labelled a_1(0)* 13 to 14 labelled b_1(0)* 13 to 40 labelled a_1(1)* 14 to 15 labelled b_1(0)* 14 to 29 labelled a_1(1)* 15 to 16 labelled a_1(0)* 16 to 5 labelled a_1(0)* 29 to 30 labelled a_1(1)* 30 to 31 labelled b_1(1)* 31 to 32 labelled b_1(1)* 32 to 33 labelled a_1(1)* 33 to 34 labelled a_1(1)* 34 to 35 labelled a_1(1)* 35 to 36 labelled a_1(1)* 36 to 37 labelled b_1(1)* 36 to 51 labelled a_1(2)* 37 to 38 labelled b_1(1)* 37 to 29 labelled a_1(1)* 38 to 39 labelled a_1(1)* 39 to 5 labelled a_1(1)* 40 to 41 labelled a_1(1)* 41 to 42 labelled b_1(1)* 42 to 43 labelled b_1(1)* 43 to 44 labelled a_1(1)* 44 to 45 labelled a_1(1)* 45 to 46 labelled a_1(1)* 46 to 47 labelled a_1(1)* 47 to 48 labelled b_1(1)* 47 to 51 labelled a_1(2)* 48 to 49 labelled b_1(1)* 48 to 29 labelled a_1(1)* 49 to 50 labelled a_1(1)* 50 to 36 labelled a_1(1)* 51 to 52 labelled a_1(2)* 52 to 53 labelled b_1(2)* 53 to 54 labelled b_1(2)* 54 to 55 labelled a_1(2)* 55 to 56 labelled a_1(2)* 56 to 57 labelled a_1(2)* 57 to 58 labelled a_1(2)* 58 to 59 labelled b_1(2)* 58 to 51 labelled a_1(2)* 59 to 60 labelled b_1(2)* 59 to 29 labelled a_1(1)* 60 to 61 labelled a_1(2)* 61 to 36 labelled a_1(2) ---------------------------------------- (4) YES
