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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
450, 451, 452, 453, 454, 455, 456, 457, 458, 459, 460, 461, 462, 463, 464, 465, 466, 467, 468, 469, 470, 471, 472, 473

Node 450 is start node and node 451 is final node.

Those nodes are connected through the following edges:

* 450 to 452 labelled c_1(0)* 451 to 451 labelled #_1(0)* 452 to 453 labelled a_1(0)* 453 to 454 labelled b_1(0)* 454 to 455 labelled a_1(0)* 455 to 456 labelled a_1(0)* 456 to 457 labelled c_1(0)* 457 to 458 labelled a_1(0)* 458 to 459 labelled b_1(0)* 459 to 460 labelled a_1(0)* 459 to 463 labelled c_1(1)* 460 to 461 labelled a_1(0)* 460 to 463 labelled c_1(1)* 461 to 462 labelled a_1(0)* 461 to 463 labelled c_1(1)* 462 to 451 labelled a_1(0)* 462 to 463 labelled c_1(1)* 463 to 464 labelled a_1(1)* 464 to 465 labelled b_1(1)* 465 to 466 labelled a_1(1)* 466 to 467 labelled a_1(1)* 467 to 468 labelled c_1(1)* 468 to 469 labelled a_1(1)* 469 to 470 labelled b_1(1)* 470 to 471 labelled a_1(1)* 470 to 463 labelled c_1(1)* 471 to 472 labelled a_1(1)* 471 to 463 labelled c_1(1)* 472 to 473 labelled a_1(1)* 472 to 463 labelled c_1(1)* 473 to 451 labelled a_1(1)* 473 to 463 labelled c_1(1)
