[标题]:A deterministic algorithm for the three-dimensional diameter problem
[作者]:MATOUSEK JIRI; SCHWARZKOPF OTFRIED
[文摘]:The following problem is considered: given an n point set P in three dimensional space, compute its diameter diam(P), defined as the maximum distance between a pair of points in P. This problem was solved by Clarkson and Shor by a randomized algorithm with optimal expected running time O(n log n). However, it seems quite difficult to construct a deterministic algorithm with a comparable asymptotic efficiency. Chazelle et al. applied Megiddo's parametric search in connection with the Clarkson-Shor algorithm and further techniques and obtained a deterministic O(n(sup 1 + epsilon)) algorithm, where epsilon greater than 0 is an arbitrarily small constant. This study improves this running time to O(n polylog n), where polylog n is used as a generic notation for a function of the form (log n)(sup c), c greater than 0 a constant). (ESA)
