Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:
G(a, X) → F(b, activate(X))
F(X, X) → H(a)
F(X, X) → A
G(a, X) → ACTIVATE(X)
H(X) → G(X, X)
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.
