Termination w.r.t. Q of the given QTRS could be proven:

(0) QTRS
(1) QTRS Reverse [EQUIVALENT, 0 ms]

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

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
100, 102, 110, 111, 112, 113, 114, 115, 116, 117, 118, 119, 120, 121, 147, 148, 149, 150, 151, 152, 153, 154, 155, 156, 157, 158

Node 100 is start node and node 102 is final node.

Those nodes are connected through the following edges:

* 100 to 110 labelled b_1(0)* 102 to 102 labelled #_1(0)* 110 to 111 labelled a_1(0)* 111 to 112 labelled a_1(0)* 112 to 113 labelled a_1(0)* 113 to 114 labelled a_1(0)* 114 to 115 labelled b_1(0)* 115 to 116 labelled a_1(0)* 115 to 147 labelled b_1(1)* 116 to 117 labelled a_1(0)* 116 to 147 labelled b_1(1)* 117 to 118 labelled a_1(0)* 117 to 147 labelled b_1(1)* 118 to 119 labelled a_1(0)* 118 to 147 labelled b_1(1)* 119 to 120 labelled a_1(0)* 119 to 147 labelled b_1(1)* 120 to 121 labelled a_1(0)* 120 to 147 labelled b_1(1)* 121 to 102 labelled a_1(0)* 121 to 147 labelled b_1(1)* 147 to 148 labelled a_1(1)* 148 to 149 labelled a_1(1)* 149 to 150 labelled a_1(1)* 150 to 151 labelled a_1(1)* 151 to 152 labelled b_1(1)* 152 to 153 labelled a_1(1)* 152 to 147 labelled b_1(1)* 153 to 154 labelled a_1(1)* 153 to 147 labelled b_1(1)* 154 to 155 labelled a_1(1)* 154 to 147 labelled b_1(1)* 155 to 156 labelled a_1(1)* 155 to 147 labelled b_1(1)* 156 to 157 labelled a_1(1)* 156 to 147 labelled b_1(1)* 157 to 158 labelled a_1(1)* 157 to 147 labelled b_1(1)* 158 to 102 labelled a_1(1)* 158 to 147 labelled b_1(1)
