Termination Proof Script

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