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, 4 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(x1)))))))) -> a(a(a(a(a(a(a(b(a(a(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(b(a(x1)))))))) -> b(a(a(a(b(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(b(a(x1)))))))) -> b(a(a(a(b(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(b(x))))))) -> b(a(a(a(b(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(b(x))))))) -> b(a(a(a(b(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(b(x))))))) -> b(a(a(a(b(a(a(a(a(a(a(x))))))))))) The certificate found is represented by the following graph. The certificate consists of the following enumerated nodes: 332, 333, 334, 335, 336, 337, 338, 339, 340, 341, 342, 343, 344, 345, 346, 347, 348, 349, 350, 351, 352, 353 Node 332 is start node and node 333 is final node. Those nodes are connected through the following edges: * 332 to 334 labelled b_1(0)* 333 to 333 labelled #_1(0)* 334 to 335 labelled a_1(0)* 335 to 336 labelled a_1(0)* 336 to 337 labelled a_1(0)* 337 to 338 labelled b_1(0)* 338 to 339 labelled a_1(0)* 338 to 344 labelled b_1(1)* 339 to 340 labelled a_1(0)* 339 to 344 labelled b_1(1)* 340 to 341 labelled a_1(0)* 340 to 344 labelled b_1(1)* 341 to 342 labelled a_1(0)* 341 to 344 labelled b_1(1)* 342 to 343 labelled a_1(0)* 342 to 344 labelled b_1(1)* 343 to 333 labelled a_1(0)* 343 to 344 labelled b_1(1)* 344 to 345 labelled a_1(1)* 345 to 346 labelled a_1(1)* 346 to 347 labelled a_1(1)* 347 to 348 labelled b_1(1)* 348 to 349 labelled a_1(1)* 348 to 344 labelled b_1(1)* 349 to 350 labelled a_1(1)* 349 to 344 labelled b_1(1)* 350 to 351 labelled a_1(1)* 350 to 344 labelled b_1(1)* 351 to 352 labelled a_1(1)* 351 to 344 labelled b_1(1)* 352 to 353 labelled a_1(1)* 352 to 344 labelled b_1(1)* 353 to 333 labelled a_1(1)* 353 to 344 labelled b_1(1) ---------------------------------------- (6) YES
