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:

911001, 911002, 911004, 911003

Node 911001 is start node and node 911002 is final node.

Those nodes are connect through the following edges:

  • 911001 to 911003 labelled g_1(0)
  • 911001 to 911002 labelled f_1(0), f_1(1)
  • 911002 to 911002 labelled #_1(0)
  • 911004 to 911002 labelled 0(0)
  • 911003 to 911004 labelled f_1(0)
