Abstract

We are given an unknown polynomial f ∈ ℤ[x] by a black box which on input a ∈ ℤ returns a value rq · f(a) for some unknown nonzero rational numbers ra. If we have appropriate upper bounds on the numerator and denominator of ra and the degree of f, then the coefficients of f can be computed in probabilistic polynomial time.
