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

   f(true, x) -> f(gt(x, 0), double(x))
   gt(s(x), 0) -> true
   gt(0, y) -> false
   gt(s(x), s(y)) -> gt(x, y)
   double(x) -> doubleAkk(x, 0)
   doubleAkk(0, y) -> y
   doubleAkk(s(x), y) -> doubleAkk(x, s(s(y)))

Q is empty.

----------------------------------------

(1) AAECC Innermost (EQUIVALENT)
We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is 
   gt(s(x), 0) -> true
   gt(0, y) -> false
   gt(s(x), s(y)) -> gt(x, y)
   double(x) -> doubleAkk(x, 0)
   doubleAkk(0, y) -> y
   doubleAkk(s(x), y) -> doubleAkk(x, s(s(y)))

The TRS R 2 is 
   f(true, x) -> f(gt(x, 0), double(x))

The signature Sigma is {f_2}
----------------------------------------

(2)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   f(true, x) -> f(gt(x, 0), double(x))
   gt(s(x), 0) -> true
   gt(0, y) -> false
   gt(s(x), s(y)) -> gt(x, y)
   double(x) -> doubleAkk(x, 0)
   doubleAkk(0, y) -> y
   doubleAkk(s(x), y) -> doubleAkk(x, s(s(y)))

The set Q consists of the following terms:

   f(true, x0)
   gt(s(x0), 0)
   gt(0, x0)
   gt(s(x0), s(x1))
   double(x0)
   doubleAkk(0, x0)
   doubleAkk(s(x0), x1)


----------------------------------------

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