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:
W(s(x1)) → V(s(x1))
V(s(x1)) → W(x1)
Used ordering: POLO with Polynomial interpretation [25]:
POL(V(x1)) = 1 + 2·x1
POL(W(x1)) = 2 + 2·x1
POL(s(x1)) = 2 + 2·x1
