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

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

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(0) -> 0
   double(s(x)) -> s(s(double(x)))

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

The signature Sigma is {f_3}
----------------------------------------

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

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

The set Q consists of the following terms:

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


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

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