Abstract

We consider a variant of Heilbronn’s triangle problem by asking for fixed integers d,k ≥2 and any integer nk for a distribution of n points in the d-dimensional unit cube [0,1] d such that the minimum volume of the convex hull of k points among these n points is as large as possible. We show that there exists a configuration of n points in [0,1] d , such that, simultaneously for j = 2, ..., k, the volume of the convex hull of any j points among these n points is Ω( 1/n (j − − 1)/(1 + |d − − j + 1|)). Moreover, for fixed kd+1 we provide a deterministic polynomial time algorithm, which finds for any integer nk a configuration of n points in [0,1] d , which achieves, simultaneously for j = d+1, ..., k, the lower bound Ω( 1/n (j − − 1)/(1 + |d − − j + 1|)) on the minimum volume of the convex hull of any j among the n points.
