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(x1))))))) -> a(a(a(a(a(a(b(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(b(a(x1))))))) -> b(a(b(a(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(a(x1))))))) -> b(a(b(a(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(x)))))) -> b(a(b(a(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(x)))))) -> b(a(b(a(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(x)))))) -> b(a(b(a(b(a(a(a(a(a(x)))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 274, 275, 276, 277, 278, 279, 280, 281, 282, 283, 284, 285, 286, 287, 288, 289, 290, 291, 292, 293 Node 274 is start node and node 275 is final node. Those nodes are connected through the following edges: * 274 to 276 labelled b_1(0)* 275 to 275 labelled #_1(0)* 276 to 277 labelled a_1(0)* 277 to 278 labelled b_1(0)* 278 to 279 labelled a_1(0)* 279 to 280 labelled b_1(0)* 280 to 281 labelled a_1(0)* 280 to 285 labelled b_1(1)* 281 to 282 labelled a_1(0)* 281 to 285 labelled b_1(1)* 282 to 283 labelled a_1(0)* 282 to 285 labelled b_1(1)* 283 to 284 labelled a_1(0)* 283 to 285 labelled b_1(1)* 284 to 275 labelled a_1(0)* 284 to 285 labelled b_1(1)* 285 to 286 labelled a_1(1)* 286 to 287 labelled b_1(1)* 287 to 288 labelled a_1(1)* 288 to 289 labelled b_1(1)* 289 to 290 labelled a_1(1)* 289 to 285 labelled b_1(1)* 290 to 291 labelled a_1(1)* 290 to 285 labelled b_1(1)* 291 to 292 labelled a_1(1)* 291 to 285 labelled b_1(1)* 292 to 293 labelled a_1(1)* 292 to 285 labelled b_1(1)* 293 to 275 labelled a_1(1)* 293 to 285 labelled b_1(1) ---------------------------------------- (6) YES
