(0) Obligation:

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

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

Q is empty.

(1) QTRS Reverse (EQUIVALENT transformation)

We applied the QTRS Reverse Processor [REVERSE].

(2) Obligation:

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

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

Q is empty.

(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

3, 4, 14, 15, 16, 17, 18, 19, 20, 21, 22, 32, 33, 34, 35, 36, 37, 38, 39, 40, 50, 51, 52, 53, 54, 57, 59, 62, 64, 77, 78, 79, 80, 81, 82, 83, 84, 85, 95, 96, 97, 98, 99, 100, 101, 102, 103, 113, 114, 115, 116, 117, 118, 119, 120, 121, 158, 159, 160, 161, 162, 163, 164, 165, 166, 167, 168, 169, 170, 171, 172, 173, 174, 175, 176, 177, 178, 179, 180, 181, 182, 183, 184, 194, 195, 196, 197, 198, 199, 200, 201, 202, 203, 204, 205, 206, 207, 208, 209, 210, 211

Node 3 is start node and node 4 is final node.
