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

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

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

Q is empty.

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

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

   a(a(a(a(b(c(b(a(x1)))))))) -> b(c(b(a(a(b(c(b(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(b(c(b(x))))))) -> b(c(b(a(a(b(c(b(a(a(a(a(x))))))))))))

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

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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
472, 473, 474, 475, 476, 477, 478, 479, 480, 481, 482, 483, 484, 485, 486, 487, 488, 489, 490, 491, 492, 493, 494, 495

Node 472 is start node and node 473 is final node.

Those nodes are connected through the following edges:

* 472 to 474 labelled b_1(0)* 473 to 473 labelled #_1(0)* 474 to 475 labelled c_1(0)* 475 to 476 labelled b_1(0)* 476 to 477 labelled a_1(0)* 477 to 478 labelled a_1(0)* 478 to 479 labelled b_1(0)* 479 to 480 labelled c_1(0)* 480 to 481 labelled b_1(0)* 481 to 482 labelled a_1(0)* 481 to 485 labelled b_1(1)* 482 to 483 labelled a_1(0)* 482 to 485 labelled b_1(1)* 483 to 484 labelled a_1(0)* 483 to 485 labelled b_1(1)* 484 to 473 labelled a_1(0)* 484 to 485 labelled b_1(1)* 485 to 486 labelled c_1(1)* 486 to 487 labelled b_1(1)* 487 to 488 labelled a_1(1)* 488 to 489 labelled a_1(1)* 489 to 490 labelled b_1(1)* 490 to 491 labelled c_1(1)* 491 to 492 labelled b_1(1)* 492 to 493 labelled a_1(1)* 492 to 485 labelled b_1(1)* 493 to 494 labelled a_1(1)* 493 to 485 labelled b_1(1)* 494 to 495 labelled a_1(1)* 494 to 485 labelled b_1(1)* 495 to 473 labelled a_1(1)* 495 to 485 labelled b_1(1)
