Abstract: We present a nearquadratic algorithm for computing the center region of a set of n points in three dimensions. This is nearly tight in the worst case since the center region can have ω(n 2) complexity. We then consider the problem of recognizing whether a given point q is a colored Tverberg point of a set of n colored points in the plane, and present the first polynomialtime algorithm for this problem.
