Termination Proof Script

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