The following pairs can be oriented strictly and are deleted.
The remaining pairs can at least be oriented weakly.
DIV(s(x), s(y), z) → DIV(x, y, z)
Used ordering: Polynomial interpretation [25,35]:
DIV(s(x), 0, s(z)) → DIV(s(x), s(z), s(z))
The value of delta used in the strict ordering is 1/4.
POL(DIV(x1, x2, x3)) = (1/4)x_1
