(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   a(b(a(a(b(a(x1)))))) -> a(a(b(a(b(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(b(a(a(b(a(x1)))))) -> b(a(a(b(a(b(a(b(a(b(a(a(x1))))))))))))

Q is empty.

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

(3) Strip Symbols Proof (SOUND)
We were given the following TRS:

   a(b(a(a(b(a(x1)))))) -> b(a(a(b(a(b(a(b(a(b(a(a(x1))))))))))))

By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: 

   a(b(a(a(b(x))))) -> b(a(a(b(a(b(a(b(a(b(a(x)))))))))))

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

(4)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   a(b(a(a(b(x))))) -> b(a(a(b(a(b(a(b(a(b(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(b(a(a(b(x))))) -> b(a(a(b(a(b(a(b(a(b(a(x)))))))))))

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
528, 529, 530, 531, 532, 533, 534, 535, 536, 537, 538, 539, 540, 541, 542, 543, 544, 545, 546, 547, 548, 549

Node 528 is start node and node 529 is final node.

Those nodes are connected through the following edges:

* 528 to 530 labelled b_1(0)* 529 to 529 labelled #_1(0)* 530 to 531 labelled a_1(0)* 531 to 532 labelled a_1(0)* 532 to 533 labelled b_1(0)* 533 to 534 labelled a_1(0)* 534 to 535 labelled b_1(0)* 535 to 536 labelled a_1(0)* 536 to 537 labelled b_1(0)* 537 to 538 labelled a_1(0)* 537 to 540 labelled b_1(1)* 538 to 539 labelled b_1(0)* 539 to 529 labelled a_1(0)* 539 to 540 labelled b_1(1)* 540 to 541 labelled a_1(1)* 541 to 542 labelled a_1(1)* 542 to 543 labelled b_1(1)* 543 to 544 labelled a_1(1)* 544 to 545 labelled b_1(1)* 545 to 546 labelled a_1(1)* 546 to 547 labelled b_1(1)* 547 to 548 labelled a_1(1)* 547 to 540 labelled b_1(1)* 548 to 549 labelled b_1(1)* 549 to 529 labelled a_1(1)* 549 to 540 labelled b_1(1)
