Q restricted rewrite system:
The TRS R consists of the following rules:

a(b(x)) → c(d(x))
d(d(x)) → b(e(x))
b(x) → d(c(x))
d(x) → x
e(c(x)) → d(a(x))
a(x) → e(d(x))

Q is empty.

(1) FlatCCProof (EQUIVALENT transformation)

We used flat context closure [ROOTLAB] As Q is empty the flat context closure was sound AND complete.

Q is empty.

(3) RootLabelingProof (EQUIVALENT transformation)

We used plain root labeling [ROOTLAB] with the following heuristic: LabelAll: All function symbols get labeled
As Q is empty the root labeling was sound AND complete.
