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

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

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

Q is empty.

(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 6. This implies Q-termination of R.
The following rules were used to construct the certificate:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

1, 2, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 73, 74, 75, 76, 77, 78, 79, 80

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

Those nodes are connected through the following edges:
