(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:
f(f(x)) → f(c(f(x)))
f(f(x)) → f(d(f(x)))
g(c(x)) → x
g(d(x)) → x
g(c(0)) → g(d(1))
g(c(1)) → g(d(0))
The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 3, 5, 8, 11, 12, 15, 16, 18, 20, 22, 24, 25, 26
Node 1 is start node and node 3 is final node.
Those nodes are connected through the following edges:
- 1 to 5 labelled f_1(0)
- 1 to 11 labelled f_1(0)
- 1 to 3 labelled f_1(0), c_1(0), d_1(0), g_1(0), 0(0), 1(0), f_1(1), c_1(1), d_1(1), g_1(1), 0(1), 1(1), 1(2), 0(2)
- 1 to 15 labelled g_1(0)
- 1 to 18 labelled f_1(1)
- 1 to 22 labelled f_1(1)
- 1 to 25 labelled g_1(1)
- 3 to 3 labelled #_1(0)
- 5 to 8 labelled c_1(0)
- 8 to 3 labelled f_1(0)
- 8 to 18 labelled f_1(1)
- 8 to 22 labelled f_1(1)
- 11 to 12 labelled d_1(0)
- 12 to 3 labelled f_1(0)
- 12 to 18 labelled f_1(1)
- 12 to 22 labelled f_1(1)
- 15 to 16 labelled d_1(0)
- 16 to 3 labelled 1(0), 0(0)

- 20 to 3 labelled f_1(1)
- 20 to 18 labelled f_1(1)
- 20 to 22 labelled f_1(1)
- 22 to 24 labelled d_1(1)
- 24 to 3 labelled f_1(1)
- 24 to 18 labelled f_1(1)
- 24 to 22 labelled f_1(1)
- 25 to 26 labelled d_1(1)
- 26 to 3 labelled 1(1), 0(1)
