How to find a point in the convex hull? or: Tukey depth and differential privacy

Finding a point in the convex hull of a set of n points in d dimensions, while protecting the privacy of the input set, in the standard differential privacy model, turns out to be a rather nontrivial algorithmic task, and the best solution we have to date takes time that is exponential in d. I will present our current technique, which is based on the Tukey depth with respect to the input set, and discuss the many open questions that it raises. Joint work with Haim Kaplan and Uri Stemmer
