Termination Proof Script

Consider the TRS R consisting of the rewrite rules
1:    f(a)  → f(b)
2:    g(b)  → g(a)
3:    f(x)  → g(x)
There are 3 dependency pairs:
4:    F(a)  → F(b)
5:    G(b)  → G(a)
6:    F(x)  → G(x)
The approximated dependency graph contains no SCCs and hence the TRS is trivially terminating.
