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

MARK₁(app₂(X1, X2)) -> MARK₁(X1)
MARK₁(app₂(X1, X2)) -> MARK₁(X2)

The TRS R consists of the following rules:

a__app₂(nil, YS) -> mark₁(YS)
a__app₂(cons₂(X, XS), YS) -> cons₂(mark₁(X), app₂(XS, YS))
a__from₁(X) -> cons₂(mark₁(X), from₁(s₁(X)))

a__zWadr₂(XS, nil) -> nil
a__zWadr₂(cons₂(X, XS), cons₂(Y, YS)) -> cons₂(a__app₂(mark₁(Y), cons₂(mark₁(X), nil)), zWadr₂(XS, YS))
a__prefix₁(L) -> cons₂(nil, zWadr₂(L, prefix₁(L)))

a__from₁(X) -> from₁(X)
a__zWadr₂(X1, X2) -> zWadr₂(X1, X2)
a__prefix₁(X) -> prefix₁(X)

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.

MARK₁(app₂(X1, X2)) -> MARK₁(X1)
MARK₁(app₂(X1, X2)) -> MARK₁(X2)

The remaining pairs can at least be oriented weakly.
none
Used ordering: Polynomial interpretation [21]:

POL(MARK₁(x₁)) = x₁
POL(app₂(x₁, x₂)) = 1 + x₁ + x₂

The following usable rules [14] were oriented: none
