Termination w.r.t. Q of the following Term Rewriting System could be proven:

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

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

Q is empty.

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

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

Q is empty.

Using Dependency Pairs [1,13] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

APP2(app2(app2(uncurry, f), x), y) -> APP2(app2(f, x), y)
APP2(app2(app2(uncurry, f), x), y) -> APP2(f, x)

The TRS R consists of the following rules:

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

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

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

APP2(app2(app2(uncurry, f), x), y) -> APP2(app2(f, x), y)
APP2(app2(app2(uncurry, f), x), y) -> APP2(f, x)

The TRS R consists of the following rules:

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

Q is empty.
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.


APP2(app2(app2(uncurry, f), x), y) -> APP2(app2(f, x), y)
APP2(app2(app2(uncurry, f), x), y) -> APP2(f, x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial Order [17,21] with Interpretation:

POL( uncurry ) = 1


POL( APP2(x1, x2) ) = x1 + x2 + 1


POL( app2(x1, x2) ) = x1 + x2



The following usable rules [14] were oriented:

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

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

app2(app2(app2(uncurry, f), x), y) -> app2(app2(f, x), y)

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