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, 1 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(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(a(b(a(x1))))))))) -> b(a(a(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(a(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(a(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(a(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(a(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: 369, 370, 436, 437, 438, 439, 440, 441, 442, 443, 444, 445, 446, 447, 448, 449, 450, 451, 452, 453, 454, 455, 456, 457, 458, 459 Node 369 is start node and node 370 is final node. Those nodes are connected through the following edges: * 369 to 436 labelled b_1(0)* 370 to 370 labelled #_1(0)* 436 to 437 labelled a_1(0)* 437 to 438 labelled a_1(0)* 438 to 439 labelled b_1(0)* 439 to 440 labelled a_1(0)* 440 to 441 labelled b_1(0)* 441 to 442 labelled a_1(0)* 441 to 448 labelled b_1(1)* 442 to 443 labelled a_1(0)* 442 to 448 labelled b_1(1)* 443 to 444 labelled a_1(0)* 443 to 448 labelled b_1(1)* 444 to 445 labelled a_1(0)* 444 to 448 labelled b_1(1)* 445 to 446 labelled a_1(0)* 445 to 448 labelled b_1(1)* 446 to 447 labelled a_1(0)* 446 to 448 labelled b_1(1)* 447 to 370 labelled a_1(0)* 447 to 448 labelled b_1(1)* 448 to 449 labelled a_1(1)* 449 to 450 labelled a_1(1)* 450 to 451 labelled b_1(1)* 451 to 452 labelled a_1(1)* 452 to 453 labelled b_1(1)* 453 to 454 labelled a_1(1)* 453 to 448 labelled b_1(1)* 454 to 455 labelled a_1(1)* 454 to 448 labelled b_1(1)* 455 to 456 labelled a_1(1)* 455 to 448 labelled b_1(1)* 456 to 457 labelled a_1(1)* 456 to 448 labelled b_1(1)* 457 to 458 labelled a_1(1)* 457 to 448 labelled b_1(1)* 458 to 459 labelled a_1(1)* 458 to 448 labelled b_1(1)* 459 to 370 labelled a_1(1)* 459 to 448 labelled b_1(1) ---------------------------------------- (6) YES
