Q restricted rewrite system:
The TRS R consists of the following rules:
f(0, 1, x) → f(h(x), h(x), x)
h(0) → 0
h(g(x, y)) → y
Q is empty.
(1) AAECC Innermost (EQUIVALENT transformation)
We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is
h(0) → 0
h(g(x, y)) → y
The TRS R 2 is
f(0, 1, x) → f(h(x), h(x), x)
The signature Sigma is {
f}
(2) Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:
f(0, 1, x) → f(h(x), h(x), x)
h(0) → 0
h(g(x, y)) → y
The set Q consists of the following terms:
f(0, 1, x0)
h(0)
h(g(x0, x1))
(3) DependencyPairsProof (EQUIVALENT transformation)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

Q DP problem:
The TRS P consists of the following rules:
F(0, 1, x) → F(h(x), h(x), x)
F(0, 1, x) → H(x)
