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

f(X) → f(a)
ba

Q is empty.

(1) AAECC Innermost (EQUIVALENT transformation)

We have applied [NOC,AAECCNOC] to switch to innermost. The TRS R 1 is

ba

The TRS R 2 is

f(X) → f(a)

The signature Sigma is {f}

(2) Obligation:

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

f(X) → f(a)
ba

The set Q consists of the following terms:

f(x0)
b

(3) DependencyPairsProof (EQUIVALENT transformation)

Using Dependency Pairs [AG00,LPAR04] we result in the following initial DP problem.

(4) Obligation:

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

F(X) → F(a)

The TRS R consists of the following rules:

f(X) → f(a)
ba

The set Q consists of the following terms:

f(x0)
b

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