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

   g(c(x1)) -> g(f(c(x1)))
   g(f(c(x1))) -> g(f(f(c(x1))))
   g(g(x1)) -> g(f(g(x1)))
   f(f(g(x1))) -> g(f(x1))

Q is empty.

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

(1) RFCMatchBoundsTRSProof (EQUIVALENT)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 3. This implies Q-termination of R.
The following rules were used to construct the certificate:

   g(c(x1)) -> g(f(c(x1)))
   g(f(c(x1))) -> g(f(f(c(x1))))
   g(g(x1)) -> g(f(g(x1)))
   f(f(g(x1))) -> g(f(x1))

The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 2, 3, 4, 5, 6, 7, 17, 18, 19, 20, 21, 22, 23, 24, 25, 29, 30, 38, 39

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

Those nodes are connected through the following edges:

* 1 to 3 labelled g_1(0)* 1 to 5 labelled g_1(0)* 1 to 20 labelled g_1(1)* 1 to 18 labelled g_1(1)* 1 to 23 labelled g_1(2)* 2 to 2 labelled #_1(0)* 3 to 4 labelled f_1(0)* 3 to 2 labelled f_1(0)* 3 to 17 labelled g_1(1)* 3 to 20 labelled g_1(1)* 3 to 29 labelled g_1(2)* 4 to 2 labelled c_1(0), g_1(0)* 4 to 18 labelled g_1(1)* 4 to 20 labelled g_1(1)* 4 to 23 labelled g_1(2)* 5 to 6 labelled f_1(0)* 6 to 7 labelled f_1(0)* 7 to 2 labelled c_1(0)* 17 to 2 labelled f_1(1)* 17 to 17 labelled g_1(1)* 17 to 29 labelled g_1(2)* 17 to 20 labelled g_1(1)* 18 to 19 labelled f_1(1)* 19 to 2 labelled c_1(1), g_1(1)* 19 to 18 labelled g_1(1)* 19 to 20 labelled g_1(1)* 19 to 23 labelled g_1(2)* 20 to 21 labelled f_1(1)* 21 to 22 labelled f_1(1)* 21 to 17 labelled g_1(1)* 21 to 29 labelled g_1(2), g_1(1)* 21 to 20 labelled g_1(1)* 22 to 2 labelled c_1(1)* 23 to 24 labelled f_1(2)* 24 to 25 labelled f_1(2)* 25 to 2 labelled c_1(2)* 29 to 30 labelled f_1(2)* 30 to 17 labelled g_1(2)* 30 to 29 labelled g_1(2)* 30 to 38 labelled g_1(3)* 30 to 20 labelled g_1(2), g_1(1)* 38 to 39 labelled f_1(3)* 39 to 29 labelled g_1(3)
