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

b(a(c(b(b(x))))) → a(c(b(b(b(a(c(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:

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

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

3, 4, 11, 12, 13, 14, 15, 16, 17, 20, 22, 24, 26, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52

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

Those nodes are connected through the following edges:

  • 3 to 11 labelled a_1(0)
  • 4 to 4 labelled #_1(0)
  • 11 to 12 labelled c_1(0)
  • 12 to 13 labelled b_1(0)
