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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
383, 384, 411, 412, 413, 414, 415, 416, 417, 418, 419, 420, 421, 422, 423, 424, 425, 426, 427, 428, 429, 430, 431, 432, 433, 434

Node 383 is start node and node 384 is final node.

Those nodes are connected through the following edges:

* 383 to 411 labelled c_1(0)* 384 to 384 labelled #_1(0)* 411 to 412 labelled c_1(0)* 412 to 413 labelled b_1(0)* 413 to 414 labelled a_1(0)* 414 to 415 labelled a_1(0)* 415 to 416 labelled a_1(0)* 416 to 417 labelled c_1(0)* 417 to 418 labelled c_1(0)* 418 to 419 labelled b_1(0)* 419 to 420 labelled a_1(0)* 419 to 423 labelled c_1(1)* 420 to 421 labelled a_1(0)* 420 to 423 labelled c_1(1)* 421 to 422 labelled a_1(0)* 421 to 423 labelled c_1(1)* 422 to 384 labelled a_1(0)* 422 to 423 labelled c_1(1)* 423 to 424 labelled c_1(1)* 424 to 425 labelled b_1(1)* 425 to 426 labelled a_1(1)* 426 to 427 labelled a_1(1)* 427 to 428 labelled a_1(1)* 428 to 429 labelled c_1(1)* 429 to 430 labelled c_1(1)* 430 to 431 labelled b_1(1)* 431 to 432 labelled a_1(1)* 431 to 423 labelled c_1(1)* 432 to 433 labelled a_1(1)* 432 to 423 labelled c_1(1)* 433 to 434 labelled a_1(1)* 433 to 423 labelled c_1(1)* 434 to 384 labelled a_1(1)* 434 to 423 labelled c_1(1)
