----------------------------------------

(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(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(b(a(x1))))))) -> b(a(b(a(a(a(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(a(a(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(a(a(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(a(a(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(a(a(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:
538, 539, 540, 541, 542, 543, 544, 545, 546, 547, 548, 549, 550, 551, 552, 553, 554, 555, 556, 557, 558, 559, 560, 561, 562, 563

Node 538 is start node and node 539 is final node.

Those nodes are connected through the following edges:

* 538 to 540 labelled b_1(0)* 539 to 539 labelled #_1(0)* 540 to 541 labelled a_1(0)* 541 to 542 labelled b_1(0)* 542 to 543 labelled a_1(0)* 543 to 544 labelled a_1(0)* 544 to 545 labelled a_1(0)* 545 to 546 labelled a_1(0)* 546 to 547 labelled b_1(0)* 547 to 548 labelled a_1(0)* 547 to 552 labelled b_1(1)* 548 to 549 labelled a_1(0)* 548 to 552 labelled b_1(1)* 549 to 550 labelled a_1(0)* 549 to 552 labelled b_1(1)* 550 to 551 labelled a_1(0)* 550 to 552 labelled b_1(1)* 551 to 539 labelled a_1(0)* 551 to 552 labelled b_1(1)* 552 to 553 labelled a_1(1)* 553 to 554 labelled b_1(1)* 554 to 555 labelled a_1(1)* 555 to 556 labelled a_1(1)* 556 to 557 labelled a_1(1)* 557 to 558 labelled a_1(1)* 558 to 559 labelled b_1(1)* 559 to 560 labelled a_1(1)* 559 to 552 labelled b_1(1)* 560 to 561 labelled a_1(1)* 560 to 552 labelled b_1(1)* 561 to 562 labelled a_1(1)* 561 to 552 labelled b_1(1)* 562 to 563 labelled a_1(1)* 562 to 552 labelled b_1(1)* 563 to 539 labelled a_1(1)* 563 to 552 labelled b_1(1)
