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

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

1, 2, 13, 14, 15, 16, 17, 18, 19, 20, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108

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

Those nodes are connected through the following edges:

  • 2 to 2 labelled #_1(0)
