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

b(a(a(b(a(b(a(x))))))) → a(a(b(a(b(b(a(a(b(x)))))))))

Q is empty.

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 3. This implies Q-termination of R.
The following rules were used to construct the certificate:

b(a(a(b(a(b(a(x))))))) → a(a(b(a(b(b(a(a(b(x)))))))))

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

2, 3, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92

Node 2 is start node and node 3 is final node.

Those nodes are connected through the following edges:
