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

h(X) → g(X, X)
g(a, X) → f(b, activate(X))
f(X, X) → h(a)
ab
activate(X) → 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:

H(X) → G(X, X)
G(a, X) → F(b, activate(X))
G(a, X) → ACTIVATE(X)
F(X, X) → H(a)
F(X, X) → A

The TRS R consists of the following rules:

h(X) → g(X, X)
g(a, X) → f(b, activate(X))
f(X, X) → h(a)
ab
activate(X) → 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:

h(X) → g(X, X)
g(a, X) → f(b, activate(X))
f(X, X) → h(a)
ab
activate(X) → X

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