Termination w.r.t. 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(b(a(x1)))))) -> a(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(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(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(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(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(x)))))))))

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
509, 510, 511, 512, 513, 514, 515, 516, 517, 518, 519, 520, 521, 522, 523, 524, 525, 526

Node 509 is start node and node 510 is final node.

Those nodes are connected through the following edges:

* 509 to 511 labelled b_1(0)* 510 to 510 labelled #_1(0)* 511 to 512 labelled a_1(0)* 512 to 513 labelled a_1(0)* 513 to 514 labelled b_1(0)* 514 to 515 labelled a_1(0)* 515 to 516 labelled b_1(0)* 516 to 517 labelled a_1(0)* 516 to 519 labelled b_1(1)* 517 to 518 labelled b_1(0)* 518 to 510 labelled a_1(0)* 518 to 519 labelled b_1(1)* 519 to 520 labelled a_1(1)* 520 to 521 labelled a_1(1)* 521 to 522 labelled b_1(1)* 522 to 523 labelled a_1(1)* 523 to 524 labelled b_1(1)* 524 to 525 labelled a_1(1)* 524 to 519 labelled b_1(1)* 525 to 526 labelled b_1(1)* 526 to 510 labelled a_1(1)* 526 to 519 labelled b_1(1)
