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(a(b(a(a(b(x1))))))))) -> a(b(a(b(a(a(b(a(a(b(a(b(x1)))))))))))) Q is empty. ---------------------------------------- (1) Strip Symbols Proof (SOUND) We were given the following TRS: b(a(a(b(a(b(a(a(b(x1))))))))) -> a(b(a(b(a(a(b(a(a(b(a(b(x1)))))))))))) By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: b(a(a(b(a(b(a(a(x)))))))) -> a(b(a(b(a(a(b(a(a(b(a(x))))))))))) ---------------------------------------- (2) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: b(a(a(b(a(b(a(a(x)))))))) -> a(b(a(b(a(a(b(a(a(b(a(x))))))))))) Q is empty. ---------------------------------------- (3) 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: b(a(a(b(a(b(a(a(x)))))))) -> a(b(a(b(a(a(b(a(a(b(a(x))))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 2, 6, 7, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70 Node 2 is start node and node 6 is final node. Those nodes are connected through the following edges: * 2 to 7 labelled a_1(0)* 6 to 6 labelled #_1(0)* 7 to 52 labelled b_1(0)* 52 to 53 labelled a_1(0)* 53 to 54 labelled b_1(0)* 54 to 55 labelled a_1(0)* 55 to 56 labelled a_1(0)* 56 to 57 labelled b_1(0)* 56 to 61 labelled a_1(1)* 57 to 58 labelled a_1(0)* 58 to 59 labelled a_1(0)* 59 to 60 labelled b_1(0)* 59 to 61 labelled a_1(1)* 60 to 6 labelled a_1(0)* 61 to 62 labelled b_1(1)* 62 to 63 labelled a_1(1)* 63 to 64 labelled b_1(1)* 64 to 65 labelled a_1(1)* 65 to 66 labelled a_1(1)* 66 to 67 labelled b_1(1)* 66 to 61 labelled a_1(1)* 67 to 68 labelled a_1(1)* 68 to 69 labelled a_1(1)* 69 to 70 labelled b_1(1)* 69 to 61 labelled a_1(1)* 70 to 6 labelled a_1(1) ---------------------------------------- (4) YES
