Q restricted rewrite system:
The TRS R consists of the following rules:
f(a, X) → f(X, X)
c → a
c → b
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(a, X) → F(X, X)
The TRS R consists of the following rules:
f(a, X) → f(X, X)
c → a
c → b
Q is empty.
We have to consider all minimal (P,Q,R)-chains.
