Termination Proof Script

Consider the TRS R consisting of the rewrite rules
1:    f(f(x))  → f(c(f(x)))
2:    f(f(x))  → f(d(f(x)))
3:    g(c(x))  → x
4:    g(d(x))  → x
5:    g(c(0))  → g(d(1))
6:    g(c(1))  → g(d(0))
There are 4 dependency pairs:
7:    F(f(x))  → F(c(f(x)))
8:    F(f(x))  → F(d(f(x)))
9:    G(c(0))  → G(d(1))
10:    G(c(1))  → G(d(0))
The approximated dependency graph contains no SCCs and hence the TRS is trivially terminating.
