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(x1))) → b(b(a(a(x1))))
b(a(x1)) → a(c(b(x1)))
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
a(a(b(x1))) → b(b(a(a(x1))))
b(a(x1)) → a(c(b(x1)))
Q is empty.
Termination of the TRS R could be shown with a Match Bound [6,7] of 3. This implies Q-termination of R.
The following rules were used to construct the certificate:
a(a(b(x1))) → b(b(a(a(x1))))
b(a(x1)) → a(c(b(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
Node 1 is start node and node 2 is final node.
Those nodes are connect through the following edges:

- 1 to 6 labelled a_1(0)
- 1 to 15 labelled a_1(1)
