By using the rule removal processor [15] with the following polynomial ordering [25], at least one Dependency Pair or term rewrite system rule of this QDP problem can be strictly oriented.
Strictly oriented dependency pairs:
new_takeWhile(Neg(Zero), Neg(Succ(Succ(wv30000)))) → new_takeWhile(Neg(Zero), Neg(Succ(wv30000)))
Used ordering: POLO with Polynomial interpretation [25]:
POL(Neg(x1)) = 2·x1
POL(Succ(x1)) = 1 + 2·x1
POL(Zero) = 0
POL(new_takeWhile(x1, x2)) = x1 + 2·x2

Q DP problem:
The TRS P consists of the following rules:
new_takeWhile1(y0, Zero, Zero, Succ(y2)) → new_takeWhile(Pos(Succ(y0)), Pos(Succ(Succ(Zero))))
new_takeWhile(Pos(Succ(Succ(Succ(y_2)))), Pos(Succ(Succ(Zero)))) → new_takeWhile1(Succ(Succ(y_2)), Succ(Zero), Succ(Zero), Succ(Succ(y_2)))

new_takeWhile(Pos(Succ(Succ(Zero))), Pos(Succ(Succ(Zero)))) → new_takeWhile1(Succ(Zero), Succ(Zero), Succ(Zero), Succ(Zero))
The TRS R consists of the following rules:
new_primPlusNat(Succ(wv510)) → Succ(wv510)
new_primPlusNat(Zero) → Zero
The set Q consists of the following terms:
new_primPlusNat(Succ(x0))
new_primPlusNat(Zero)
We have to consider all minimal (P,Q,R)-chains.
As all Q-normal forms are R-normal forms we are in the innermost case. Hence, by the usable rules processor [15] we can delete all non-usable rules [17] from R.
