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

   a(b(a(a(a(b(a(a(x1)))))))) -> a(a(a(b(a(a(a(b(a(b(a(a(a(b(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(b(a(a(a(b(a(x1)))))))) -> b(a(a(a(b(a(b(a(a(a(b(a(a(a(x1))))))))))))))

Q is empty.

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

(3) Strip Symbols Proof (SOUND)
We were given the following TRS:

   a(a(b(a(a(a(b(a(x1)))))))) -> b(a(a(a(b(a(b(a(a(a(b(a(a(a(x1))))))))))))))

By stripping symbols from the only rule of the system, we obtained the following TRS [ENDRULLIS]: 

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

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

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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
6, 8, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 59, 60, 61, 62, 63, 64, 65, 67, 68, 70, 72, 74

Node 6 is start node and node 8 is final node.

Those nodes are connected through the following edges:

* 6 to 34 labelled b_1(0)* 8 to 8 labelled #_1(0)* 34 to 35 labelled a_1(0)* 35 to 36 labelled a_1(0)* 36 to 37 labelled a_1(0)* 37 to 38 labelled b_1(0)* 38 to 39 labelled a_1(0)* 39 to 40 labelled b_1(0)* 40 to 41 labelled a_1(0)* 41 to 42 labelled a_1(0)* 41 to 59 labelled b_1(1)* 42 to 43 labelled a_1(0)* 43 to 44 labelled b_1(0)* 44 to 45 labelled a_1(0)* 44 to 59 labelled b_1(1)* 45 to 8 labelled a_1(0)* 45 to 59 labelled b_1(1)* 59 to 60 labelled a_1(1)* 60 to 61 labelled a_1(1)* 61 to 62 labelled a_1(1)* 62 to 63 labelled b_1(1)* 63 to 64 labelled a_1(1)* 64 to 65 labelled b_1(1)* 65 to 67 labelled a_1(1)* 67 to 68 labelled a_1(1)* 67 to 59 labelled b_1(1)* 68 to 70 labelled a_1(1)* 70 to 72 labelled b_1(1)* 72 to 74 labelled a_1(1)* 72 to 59 labelled b_1(1)* 74 to 8 labelled a_1(1)* 74 to 59 labelled b_1(1)
