The following pairs can be oriented strictly and are deleted.
The remaining pairs can at least be oriented weakly.

Used ordering: Polynomial interpretation [25,35]:
AP(ap(ff, x), x) → AP(x, ap(ff, x))
The value of delta used in the strict ordering is 3/16.
POL(ap(x1, x2)) = (1/4)x_1 + (1/4)x_2
POL(cons) = 0
POL(AP(x1, x2)) = (1/4)x_1 + (1/4)x_2
