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)
a → b
activate(X) → X
Q is empty.
(1) DependencyPairsProof (EQUIVALENT transformation)
Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

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)
a → b
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.
