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

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

Q is empty.

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

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

The TRS R 2 is 
   f(true, s(x)) -> f(eq(0, minus(x, x)), double(s(x)))

The signature Sigma is {f_2}
