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

   f(tt, x) -> f(swap(x, 0), s(x))
   swap(s(x), y) -> swap(x, s(y))
   swap(0, s(y)) -> decr(s(y))
   decr(s(y)) -> decr(y)
   decr(0) -> tt

Q is empty.

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

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

The TRS R 2 is 
   f(tt, x) -> f(swap(x, 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(swap(x, 0), s(x))
   swap(s(x), y) -> swap(x, s(y))
   swap(0, s(y)) -> decr(s(y))
   decr(s(y)) -> decr(y)
   decr(0) -> tt

The set Q consists of the following terms:

   f(tt, x0)
   swap(s(x0), x1)
   swap(0, s(x0))
   decr(s(x0))
   decr(0)


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

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