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

f(x, x) → a
f(g(x), y) → f(x, y)

Q is empty.

We have applied [15,7] to switch to innermost. The TRS R 1 is none

The TRS R 2 is

f(x, x) → a
f(g(x), y) → f(x, y)

The signature Sigma is {a, f}

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:

The set Q consists of the following terms:

f(x0, x0)
f(g(x0), x1)

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

We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [13].


The following pairs can be oriented strictly and are deleted.


F(g(x), y) → F(x, y)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Combined order from the following AFS and order.

Q DP problem:
P is empty.
The TRS R consists of the following rules:

f(x, x) → a
f(g(x), y) → f(x, y)

The set Q consists of the following terms:

We have to consider all minimal (P,Q,R)-chains.
The TRS P is empty. Hence, there is no (P,Q,R) chain.
