Termination w.r.t. Q of the following Term Rewriting System could be proven:

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.

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.

Termination of the TRS R could be shown with a Match Bound [6,7] 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, 4, 5, 3, 7, 6, 9, 10, 8, 12, 11, 14, 15, 13, 17, 16, 19, 20, 18, 22, 21, 24, 25, 23, 27, 26, 29, 30, 28, 32, 31, 34, 35, 33, 37, 36, 42, 41, 40, 39, 38

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

Those nodes are connect through the following edges:
