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

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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
487, 488, 489, 490, 491, 492, 493, 494, 495, 496, 497, 498, 499, 500, 501, 502, 503, 504, 505, 506, 507, 508, 509, 510, 511, 512

Node 487 is start node and node 488 is final node.

Those nodes are connected through the following edges:

* 487 to 489 labelled c_1(0)* 488 to 488 labelled #_1(0)* 489 to 490 labelled b_1(0)* 490 to 491 labelled b_1(0)* 491 to 492 labelled a_1(0)* 492 to 493 labelled a_1(0)* 493 to 494 labelled c_1(0)* 494 to 495 labelled b_1(0)* 495 to 496 labelled b_1(0)* 496 to 497 labelled a_1(0)* 496 to 501 labelled c_1(1)* 497 to 498 labelled a_1(0)* 497 to 501 labelled c_1(1)* 498 to 499 labelled a_1(0)* 498 to 501 labelled c_1(1)* 499 to 500 labelled a_1(0)* 499 to 501 labelled c_1(1)* 500 to 488 labelled a_1(0)* 500 to 501 labelled c_1(1)* 501 to 502 labelled b_1(1)* 502 to 503 labelled b_1(1)* 503 to 504 labelled a_1(1)* 504 to 505 labelled a_1(1)* 505 to 506 labelled c_1(1)* 506 to 507 labelled b_1(1)* 507 to 508 labelled b_1(1)* 508 to 509 labelled a_1(1)* 508 to 501 labelled c_1(1)* 509 to 510 labelled a_1(1)* 509 to 501 labelled c_1(1)* 510 to 511 labelled a_1(1)* 510 to 501 labelled c_1(1)* 511 to 512 labelled a_1(1)* 511 to 501 labelled c_1(1)* 512 to 488 labelled a_1(1)* 512 to 501 labelled c_1(1)
