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