Abstract

We study two problems for a given n-point set in 3-space: Finding a largest subset with diameter at most one, and finding a subset of k points with minimum diameter. For the former problem we suggest several polynomial-time algorithms with constant approximation factors, the best of which has factor 7r/ arccos(1/3) < 2.553. For the latter problem we observe that there is a polynomial-time approximation scheme.
