Termination w.r.t. Q of the following Term Rewriting System could be proven:
Q restricted rewrite system:
The TRS R consists of the following rules:
f(f(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
Q is empty.

Q restricted rewrite system:
The TRS R consists of the following rules:
f(f(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
Q is empty.
Termination of the TRS R could be shown with a Match Bound [6,7] of 2. This implies Q-termination of R.
The following rules were used to construct the certificate:
f(f(X)) → f(a(b(f(X))))
f(a(g(X))) → b(X)
b(X) → a(X)
The certificate found is represented by the following graph.
The certificate consists of the following enumerated nodes:
1, 2, 4, 5, 3, 7, 8, 6
Node 1 is start node and node 2 is final node.
Those nodes are connect through the following edges:
- 1 to 2 labelled a_1(0), b_1(0), a_1(1)
- 1 to 3 labelled f_1(0)
- 2 to 2 labelled #_1(0)
- 4 to 5 labelled b_1(0), a_1(1)
- 5 to 2 labelled f_1(0), b_1(1), a_1(2)
- 5 to 6 labelled f_1(1)
- 3 to 4 labelled a_1(0)
- 7 to 8 labelled b_1(1), a_1(2)
- 8 to 2 labelled f_1(1), b_1(1), a_1(2)
- 8 to 6 labelled f_1(1)
- 6 to 7 labelled a_1(1)
