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

f(f(x)) → f(x)
g(0) → g(f(0))

Q is empty.

(1) RFCMatchBoundsTRSProof (EQUIVALENT transformation)

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:

f(f(x)) → f(x)
g(0) → g(f(0))

The certificate found is represented by the following graph.

The certificate consists of the following enumerated nodes:

1, 3, 6, 7

Node 1 is start node and node 3 is final node.

Those nodes are connected through the following edges:

  • 1 to 3 labelled f_1(0), f_1(1)
  • 1 to 6 labelled g_1(0)
  • 3 to 3 labelled #_1(0)
  • 6 to 7 labelled f_1(0)
  • 7 to 3 labelled 0(0)

(2) YES
