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

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

Q is empty.

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 2. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

1, 3, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114, 115, 116

Node 1 is start node and node 3 is final node.

Those nodes are connected through the following edges:

  • 1 to 85 labelled a_1(0)
  • 3 to 3 labelled #_1(0)
  • 85 to 86 labelled a_1(0)
  • 86 to 87 labelled b_1(0)

  • 88 to 89 labelled a_1(0)
  • 89 to 90 labelled a_1(0)
  • 90 to 91 labelled a_1(0)
  • 91 to 92 labelled b_1(0)
  • 91 to 101 labelled a_1(1)
  • 92 to 3 labelled b_1(0)
  • 92 to 93 labelled a_1(1)
  • 93 to 94 labelled a_1(1)
  • 94 to 95 labelled b_1(1)
  • 95 to 96 labelled b_1(1)
  • 96 to 97 labelled a_1(1)
  • 97 to 98 labelled a_1(1)

  • 110 to 111 labelled b_1(2)
  • 111 to 112 labelled b_1(2)
