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:

app(app(app(uncurry, f), x), y) → app(app(f, x), y)

Q is empty.

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

app(app(app(uncurry, f), x), y) → app(app(f, x), y)

Q is empty.

Using Dependency Pairs [1,15] we result in the following initial DP problem:
Q DP problem:
The TRS P consists of the following rules:

APP(app(app(uncurry, f), x), y) → APP(app(f, x), y)
APP(app(app(uncurry, f), x), y) → APP(f, x)

The TRS R consists of the following rules:

app(app(app(uncurry, f), x), y) → app(app(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:

APP(app(app(uncurry, f), x), y) → APP(app(f, x), y)
APP(app(app(uncurry, f), x), y) → APP(f, x)

The TRS R consists of the following rules:

app(app(app(uncurry, f), x), y) → app(app(f, x), y)

Q is empty.
We have to consider all minimal (P,Q,R)-chains.
We use the reduction pair processor [15].


The following pairs can be oriented strictly and are deleted.


APP(app(app(uncurry, f), x), y) → APP(app(f, x), y)
APP(app(app(uncurry, f), x), y) → APP(f, x)
The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [25,35]:

POL(APP(x1, x2)) = (1/4)x_1 + x_2   
POL(app(x1, x2)) = (1/4)x_1 + (4)x_2   
POL(uncurry) = 1/4   
The value of delta used in the strict ordering is 1/256.
The following usable rules [17] were oriented:

app(app(app(uncurry, f), x), y) → app(app(f, x), y)

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

app(app(app(uncurry, f), x), y) → app(app(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.
