Q of the given QTRS could be proven: (0) QTRS (1) QTRS Reverse [EQUIVALENT, 0 ms] (2) QTRS (3) RFCMatchBoundsTRSProof [EQUIVALENT, 9 ms] (4) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(a(b(b(a(b(x1)))))) -> a(b(b(a(a(b(b(a(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: b(a(b(b(a(a(x1)))))) -> a(b(b(a(a(b(b(a(x1)))))))) 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(b(b(a(a(x1)))))) -> a(b(b(a(a(b(b(a(x1)))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93 Node 64 is start node and node 65 is final node. Those nodes are connected through the following edges: * 64 to 66 labelled a_1(0)* 65 to 65 labelled #_1(0)* 66 to 67 labelled b_1(0)* 67 to 68 labelled b_1(0)* 68 to 69 labelled a_1(0)* 69 to 70 labelled a_1(0)* 70 to 71 labelled b_1(0)* 70 to 80 labelled a_1(1)* 71 to 72 labelled b_1(0)* 71 to 73 labelled a_1(1)* 72 to 65 labelled a_1(0)* 73 to 74 labelled b_1(1)* 74 to 75 labelled b_1(1)* 75 to 76 labelled a_1(1)* 76 to 77 labelled a_1(1)* 77 to 78 labelled b_1(1)* 77 to 87 labelled a_1(2)* 78 to 79 labelled b_1(1)* 78 to 73 labelled a_1(1)* 79 to 65 labelled a_1(1)* 80 to 81 labelled b_1(1)* 81 to 82 labelled b_1(1)* 82 to 83 labelled a_1(1)* 83 to 84 labelled a_1(1)* 84 to 85 labelled b_1(1)* 84 to 87 labelled a_1(2)* 85 to 86 labelled b_1(1)* 85 to 73 labelled a_1(1)* 86 to 77 labelled a_1(1)* 87 to 88 labelled b_1(2)* 88 to 89 labelled b_1(2)* 89 to 90 labelled a_1(2)* 90 to 91 labelled a_1(2)* 91 to 92 labelled b_1(2)* 91 to 87 labelled a_1(2)* 92 to 93 labelled b_1(2)* 92 to 73 labelled a_1(1)* 93 to 77 labelled a_1(2) ---------------------------------------- (4) YES
