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

   g(tt, x, y) -> g(swap(x, y), s(x), y)
   swap(0, y) -> tt
   swap(s(x), y) -> swap(x, s(y))

Q is empty.

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

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

The TRS R 2 is 
   g(tt, x, y) -> g(swap(x, y), s(x), y)

The signature Sigma is {g_3}
----------------------------------------

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

   g(tt, x, y) -> g(swap(x, y), s(x), y)
   swap(0, y) -> tt
   swap(s(x), y) -> swap(x, s(y))

The set Q consists of the following terms:

   g(tt, x0, x1)
   swap(0, x0)
   swap(s(x0), x1)


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

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

(4)
Obligation:
Q DP problem:
The TRS P consists of the following rules:

   G(tt, x, y) -> G(swap(x, y), s(x), y)
   G(tt, x, y) -> SWAP(x, y)
   SWAP(s(x), y) -> SWAP(x, s(y))

The TRS R consists of the following rules:

   g(tt, x, y) -> g(swap(x, y), s(x), y)
   swap(0, y) -> tt
   swap(s(x), y) -> swap(x, s(y))

The set Q consists of the following terms:

   g(tt, x0, x1)
