(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(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(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(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(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(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(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:
379, 380, 381, 382, 383, 384, 385, 386, 387, 388, 389, 390, 391, 392, 393, 394, 395, 396, 397, 398, 399, 400, 401, 402

Node 379 is start node and node 380 is final node.

Those nodes are connected through the following edges:

* 379 to 381 labelled c_1(0)* 380 to 380 labelled #_1(0)* 381 to 382 labelled b_1(0)* 382 to 383 labelled b_1(0)* 383 to 384 labelled a_1(0)* 384 to 385 labelled c_1(0)* 385 to 386 labelled b_1(0)* 386 to 387 labelled b_1(0)* 387 to 388 labelled a_1(0)* 387 to 392 labelled c_1(1)* 388 to 389 labelled a_1(0)* 388 to 392 labelled c_1(1)* 389 to 390 labelled a_1(0)* 389 to 392 labelled c_1(1)* 390 to 391 labelled a_1(0)* 390 to 392 labelled c_1(1)* 391 to 380 labelled a_1(0)* 391 to 392 labelled c_1(1)* 392 to 393 labelled b_1(1)* 393 to 394 labelled b_1(1)* 394 to 395 labelled a_1(1)* 395 to 396 labelled c_1(1)* 396 to 397 labelled b_1(1)* 397 to 398 labelled b_1(1)* 398 to 399 labelled a_1(1)* 398 to 392 labelled c_1(1)* 399 to 400 labelled a_1(1)* 399 to 392 labelled c_1(1)* 400 to 401 labelled a_1(1)* 400 to 392 labelled c_1(1)* 401 to 402 labelled a_1(1)* 401 to 392 labelled c_1(1)* 402 to 380 labelled a_1(1)* 402 to 392 labelled c_1(1)
