Q restricted rewrite system:
The TRS R consists of the following rules:
g(x, y) → x
g(x, y) → y
f(s(x), y, y) → f(y, x, s(x))
Q is empty.
(1) DependencyPairsProof (EQUIVALENT transformation)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.
(2) Obligation:
Q DP problem:
The TRS P consists of the following rules:
F(s(x), y, y) → F(y, x, s(x))
The TRS R consists of the following rules:
g(x, y) → x
g(x, y) → y
f(s(x), y, y) → f(y, x, s(x))
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
