%T An O(n^{5/2} log n) Algorithm for the Rectilinear Minimum Link-Distance Problem in Three Dimensions (Extended Abstract) %A Robert Scot Drysdale %A Clifford Stein %A David P. Wagner %R Technical Report TR2005-538 %I Dartmouth College, Computer Science %C Hanover, NH %D May 2005 %U http://www.cs.dartmouth.edu/reports/TR2005-538.pdf %X In this paper we consider the Rectilinear Minimum Link-Distance Problem in Three Dimensions. The problem is well studied in two dimensions, but is relatively unexplored in higher dimensions. We solve the problem in O(B n log n) time, where n is the number of corners among all obstacles, and B is the size of a BSP decomposition of the space containing the obstacles. It has been shown that in the worst case B = Theta(n^{3/2}), giving us an overall worst case time of O(n^{5/2} log n). Previously known algorithms have had worst-case running times of Omega(n^3). %Z Submitted to CCCG 2005
