(3) RFCMatchBoundsTRSProof (EQUIVALENT transformation)
Termination of the TRS R could be shown with a Match Bound [MATCHBOUNDS1,MATCHBOUNDS2] of 5. This implies Q-termination of R.
The following rules were used to construct the certificate:
f(f(X)) → n__f(g(n__f(c(X))))
c(X) → activate(d(X))
h(X) → n__d(c(X))
f(X) → n__f(X)
d(X) → n__d(X)
n__f(activate(X)) → f(X)
n__d(activate(X)) → d(X)
activate(X) → X
The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
2, 3, 9, 10, 11, 12, 13, 14, 15, 16, 17, 19
Node 2 is start node and node 3 is final node.
Those nodes are connected through the following edges:
