(0) Obligation:

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

b(c(b(c(a(a(x)))))) → a(a(a(b(c(b(c(b(c(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:

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

Q is empty.

(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 4. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

2, 3, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 45, 46, 47, 48, 49, 50, 51, 52, 59, 61, 63, 64, 65, 66, 67, 68, 77, 78, 79, 80, 81, 82, 83, 84, 93, 94, 95, 96, 97, 98, 99, 100, 109, 110, 111, 112, 113, 114, 115, 116

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