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

   g(x, x, x) -> g(c, d, e)
   g(x, y, x) -> g(c, d, e)
   s(f(x, y)) -> f(y, f(s(s(x)), a))
   h(h(x, a), y) -> h(h(a, y), h(a, x))
   f(x, f(y, f(x, y))) -> f(a, f(x, f(y, b)))
   f(h(a, y), g(x, b, a)) -> h(f(x, s(y)), s(b))
   h(f(x, s(y)), b) -> f(a, g(y, a, f(s(x), a)))
   f(x, g(x, a, f(s(x), y))) -> f(h(x, b), g(a, b, y))
   s(y) -> b

Q is empty.

(1) DependencyPairsProof (EQUIVALENT)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

The TRS P consists of the following rules:

   G(x, x, x) -> G(c, d, e)
   G(x, y, x) -> G(c, d, e)
