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

ag(c)
g(a) → b
f(g(X), b) → f(a, 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:

AG(c)
F(g(X), b) → F(a, X)
F(g(X), b) → A

The TRS R consists of the following rules:

ag(c)
g(a) → b
f(g(X), b) → f(a, X)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.

(3) DependencyGraphProof (EQUIVALENT transformation)

The approximation of the Dependency Graph [LPAR04,FROCOS05,EDGSTAR] contains 1 SCC with 2 less nodes.

(4) Obligation:

Q DP problem:
The TRS P consists of the following rules:

F(g(X), b) → F(a, X)

The TRS R consists of the following rules:

ag(c)
g(a) → b
f(g(X), b) → f(a, X)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
