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

(2) YES

Q restricted rewrite system:
The TRS R consists of the following rules:

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

Q is empty.

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

(1) RFCMatchBoundsTRSProof (EQUIVALENT)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 4. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42

Node 1 is start node and node 2 is final node.

Those nodes are connected through the following edges:

* 1 to 3 labelled b_1(0)* 2 to 2 labelled #_1(0)* 3 to 4 labelled b_1(0)* 4 to 5 labelled b_1(0)* 5 to 6 labelled a_1(0)* 5 to 13 labelled b_1(1)* 6 to 7 labelled a_1(0)* 6 to 8 labelled b_1(1)* 7 to 2 labelled a_1(0)* 7 to 8 labelled b_1(1)* 8 to 9 labelled b_1(1)* 9 to 10 labelled b_1(1)* 10 to 11 labelled a_1(1)* 10 to 18 labelled b_1(2)* 11 to 12 labelled a_1(1)* 11 to 8 labelled b_1(1)* 12 to 2 labelled a_1(1)* 12 to 8 labelled b_1(1)* 13 to 14 labelled b_1(1)* 14 to 15 labelled b_1(1)* 15 to 16 labelled a_1(1)* 16 to 17 labelled a_1(1)* 16 to 23 labelled b_1(2)* 17 to 9 labelled a_1(1)* 18 to 19 labelled b_1(2)* 19 to 20 labelled b_1(2)* 20 to 21 labelled a_1(2)* 21 to 22 labelled a_1(2)* 21 to 23 labelled b_1(2)* 22 to 9 labelled a_1(2)* 23 to 24 labelled b_1(2)* 24 to 25 labelled b_1(2)* 25 to 26 labelled a_1(2)* 26 to 27 labelled a_1(2)* 26 to 28 labelled b_1(3)* 27 to 18 labelled a_1(2)* 28 to 29 labelled b_1(3)* 29 to 30 labelled b_1(3)* 30 to 31 labelled a_1(3)* 30 to 38 labelled b_1(4)* 31 to 32 labelled a_1(3)* 32 to 20 labelled a_1(3)* 32 to 33 labelled b_1(3)* 33 to 34 labelled b_1(3)* 34 to 35 labelled b_1(3)* 35 to 36 labelled a_1(3)* 36 to 37 labelled a_1(3)* 37 to 24 labelled a_1(3)* 38 to 39 labelled b_1(4)* 39 to 40 labelled b_1(4)* 40 to 41 labelled a_1(4)* 41 to 42 labelled a_1(4)* 42 to 34 labelled a_1(4)
