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, 0 ms] (6) YES ---------------------------------------- (0) Obligation: Q restricted rewrite system: The TRS R consists of the following rules: a(b(a(a(a(a(a(a(a(x1))))))))) -> a(a(a(a(a(a(a(a(b(a(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(a(a(b(a(x1))))))))) -> b(a(b(a(a(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(a(a(b(a(x1))))))))) -> b(a(b(a(a(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(a(a(b(x)))))))) -> b(a(b(a(a(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(a(a(b(x)))))))) -> b(a(b(a(a(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(a(a(b(x)))))))) -> b(a(b(a(a(a(a(a(a(a(x)))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 162, 163, 182, 183, 184, 185, 186, 187, 188, 189, 190, 191, 192, 193, 194, 195, 196, 197, 198, 199 Node 162 is start node and node 163 is final node. Those nodes are connected through the following edges: * 162 to 182 labelled b_1(0)* 163 to 163 labelled #_1(0)* 182 to 183 labelled a_1(0)* 183 to 184 labelled b_1(0)* 184 to 185 labelled a_1(0)* 184 to 191 labelled b_1(1)* 185 to 186 labelled a_1(0)* 185 to 191 labelled b_1(1)* 186 to 187 labelled a_1(0)* 186 to 191 labelled b_1(1)* 187 to 188 labelled a_1(0)* 187 to 191 labelled b_1(1)* 188 to 189 labelled a_1(0)* 188 to 191 labelled b_1(1)* 189 to 190 labelled a_1(0)* 189 to 191 labelled b_1(1)* 190 to 163 labelled a_1(0)* 190 to 191 labelled b_1(1)* 191 to 192 labelled a_1(1)* 192 to 193 labelled b_1(1)* 193 to 194 labelled a_1(1)* 193 to 191 labelled b_1(1)* 194 to 195 labelled a_1(1)* 194 to 191 labelled b_1(1)* 195 to 196 labelled a_1(1)* 195 to 191 labelled b_1(1)* 196 to 197 labelled a_1(1)* 196 to 191 labelled b_1(1)* 197 to 198 labelled a_1(1)* 197 to 191 labelled b_1(1)* 198 to 199 labelled a_1(1)* 198 to 191 labelled b_1(1)* 199 to 163 labelled a_1(1)* 199 to 191 labelled b_1(1) ---------------------------------------- (6) YES
