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

(0) QTRS
(1) Strip Symbols Proof [SOUND, 0 ms]
(2) QTRS
(3) RFCMatchBoundsTRSProof [EQUIVALENT, 4 ms]
(4) YES

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

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

Q is empty.

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

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

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

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

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

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

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

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

Q is empty.

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

(3) 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:

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67

Node 42 is start node and node 43 is final node.

Those nodes are connected through the following edges:

* 42 to 44 labelled a_1(0)* 43 to 43 labelled #_1(0)* 44 to 45 labelled a_1(0)* 45 to 46 labelled a_1(0)* 46 to 47 labelled b_1(0)* 47 to 48 labelled b_1(0)* 48 to 49 labelled a_1(0)* 49 to 50 labelled a_1(0)* 50 to 51 labelled a_1(0)* 51 to 52 labelled b_1(0)* 51 to 56 labelled a_1(1)* 52 to 53 labelled a_1(0)* 53 to 54 labelled a_1(0)* 54 to 55 labelled a_1(0)* 55 to 43 labelled b_1(0)* 55 to 56 labelled a_1(1)* 56 to 57 labelled a_1(1)* 57 to 58 labelled a_1(1)* 58 to 59 labelled b_1(1)* 59 to 60 labelled b_1(1)* 60 to 61 labelled a_1(1)* 61 to 62 labelled a_1(1)* 62 to 63 labelled a_1(1)* 63 to 64 labelled b_1(1)* 63 to 56 labelled a_1(1)* 64 to 65 labelled a_1(1)* 65 to 66 labelled a_1(1)* 66 to 67 labelled a_1(1)* 67 to 43 labelled b_1(1)* 67 to 56 labelled a_1(1)
