Termination Proof Script

Consider the TRS R consisting of the rewrite rules
1:    f(x,x)  → f(i(x),g(g(x)))
2:    f(x,y)  → x
3:    g(x)  → i(x)
4:    f(x,i(x))  → f(x,x)
5:    f(i(x),i(g(x)))  → a
There are 4 dependency pairs:
6:    F(x,x)  → F(i(x),g(g(x)))
7:    F(x,x)  → G(g(x))
8:    F(x,x)  → G(x)
9:    F(x,i(x))  → F(x,x)
The approximated dependency graph contains one SCC: {6,9}.
