(0)
Obligation:
Q restricted rewrite system:
The TRS R consists of the following rules:

   f(tt, x) -> f(eq(toOne(x), s(0)), s(x))
   eq(s(x), s(y)) -> eq(x, y)
   eq(0, 0) -> tt
   toOne(s(s(x))) -> toOne(s(x))
   toOne(s(0)) -> s(0)

Q is empty.

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

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

The TRS R 2 is 
   f(tt, x) -> f(eq(toOne(x), s(0)), s(x))

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

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

   f(tt, x) -> f(eq(toOne(x), s(0)), s(x))
   eq(s(x), s(y)) -> eq(x, y)
   eq(0, 0) -> tt
   toOne(s(s(x))) -> toOne(s(x))
   toOne(s(0)) -> s(0)

The set Q consists of the following terms:

   f(tt, x0)
   eq(s(x0), s(x1))
   eq(0, 0)
   toOne(s(s(x0)))
   toOne(s(0))


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

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