If Fd (N,N)=Ω(N1+ε), for some fixed e{open}&gt;0, then the running time improves to O(Fd (N,N)). Furthermore, we describe a randomized algorithm to compute a bichromatic closest pair in expected time O((nm log n log m)2/3+m log2 n+n log2 m) in E3, which yields an O(N4/3 log4/3 N) expected time, algorithm for computing a Euclidean minimum spanning tree of N points in E3. In d≥4 dimensions we obtain expected time O((nm)1-1/([d/2]+1)+ε+m log n+n log m) for the bichromatic closest pair problem and O(N2-2/([d/2]+1)ε) for the Euclidean minimum spanning tree problem, for any positive e{open}."}],"year":"1991","title":"Euclidean minimum spanning trees and bichromatic closest pairs","_id":"4061","status":"public","publication":"Discrete & Computational Geometry","oa_version":"Published Version","doi":"10.1007/BF02574698","day":"01","scopus_import":"1","publist_id":"2062","article_processing_charge":"No","extern":"1","intvolume":"         6","date_published":"1991-12-01T00:00:00Z","issue":"1","oa":1,"type":"journal_article","quality_controlled":"1","acknowledgement":"The first, second, and fourth authors acknowledge support from the Center for Discrete Mathematics and Theoretical Computer Science (DIMACS), a National Science Foundation Science and Technology Center under NSF Grant STC 88-09648.
