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

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

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

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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
273, 274, 395, 396, 397, 398, 399, 400, 401, 402, 403, 404, 405, 406, 407, 408, 409, 410, 411, 412, 413, 414, 415, 416

Node 273 is start node and node 274 is final node.

Those nodes are connected through the following edges:

* 273 to 395 labelled c_1(0)* 274 to 274 labelled #_1(0)* 395 to 396 labelled b_1(0)* 396 to 397 labelled b_1(0)* 397 to 398 labelled a_1(0)* 398 to 399 labelled a_1(0)* 399 to 400 labelled c_1(0)* 400 to 401 labelled b_1(0)* 401 to 402 labelled b_1(0)* 402 to 403 labelled a_1(0)* 402 to 406 labelled c_1(1)* 403 to 404 labelled a_1(0)* 403 to 406 labelled c_1(1)* 404 to 405 labelled a_1(0)* 404 to 406 labelled c_1(1)* 405 to 274 labelled a_1(0)* 405 to 406 labelled c_1(1)* 406 to 407 labelled b_1(1)* 407 to 408 labelled b_1(1)* 408 to 409 labelled a_1(1)* 409 to 410 labelled a_1(1)* 410 to 411 labelled c_1(1)* 411 to 412 labelled b_1(1)* 412 to 413 labelled b_1(1)* 413 to 414 labelled a_1(1)* 413 to 406 labelled c_1(1)* 414 to 415 labelled a_1(1)* 414 to 406 labelled c_1(1)* 415 to 416 labelled a_1(1)* 415 to 406 labelled c_1(1)* 416 to 274 labelled a_1(1)* 416 to 406 labelled c_1(1)
