Abstract

An 0(n log n) algorithm is presented for computing the maximum euclidean distance between two finite planar sets of n points. When the n points form the vertices of simple polygons this complexity can be reduced to 0(n). The algorithm is empirically compared to the brute-force method as well as an alternate 0(n2) algorithm. Both the 0(n log n) and 0(n2) algorithms run in 0(n) expected time for many underlying distributions of the points. An ε{lunate}-approximate algorithm can be obtained that runs in 0(n + 1 ε{lunate}) worst-case time.
