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

   g(s(x)) -> f(x)
   f(0) -> s(0)
   f(s(x)) -> s(s(g(x)))
   g(0) -> 0

Q is empty.

----------------------------------------

(1) RFCMatchBoundsTRSProof (EQUIVALENT)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 1. This implies Q-termination of R.
The following rules were used to construct the certificate:

   g(s(x)) -> f(x)
   f(0) -> s(0)
   f(s(x)) -> s(s(g(x)))
   g(0) -> 0

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 2, 3, 4, 5, 6, 7, 8

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

Those nodes are connected through the following edges:

* 1 to 2 labelled f_1(0), 0(0)* 1 to 3 labelled s_1(0)* 1 to 4 labelled s_1(0)* 1 to 6 labelled s_1(1)* 1 to 7 labelled s_1(1)* 2 to 2 labelled #_1(0)* 3 to 2 labelled 0(0)* 4 to 5 labelled s_1(0)* 5 to 2 labelled g_1(0), f_1(1), 0(1)* 5 to 5 labelled s_1(1)* 5 to 7 labelled s_1(1)* 6 to 2 labelled 0(1)* 7 to 8 labelled s_1(1)* 8 to 2 labelled g_1(1), f_1(1), 0(1)* 8 to 5 labelled s_1(1)* 8 to 7 labelled s_1(1)
