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

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

Q is empty.

(1) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

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:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

3, 4, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112

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

Those nodes are connected through the following edges:

  • 3 to 29 labelled a_1(0)
  • 4 to 4 labelled #_1(0)
