[{"abstract":[{"text":"We present an algorithm to compute a Euclidean minimum spanning tree of a given set S of N points in Ed in time O(Fd (N,N) logd N), where Fd (n,m) is the time required to compute a bichromatic closest pair among n red and m green points in Ed . If Fd (N,N)=Ω(N1+ε), for some fixed e{open}>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}.","lang":"eng"}],"date_published":"1991-12-01T00:00:00Z","title":"Euclidean minimum spanning trees and bichromatic closest pairs","publication":"Discrete & Computational Geometry","month":"12","_id":"4061","year":"1991","publication_status":"published","quality_controlled":0,"doi":"10.1007/BF02574698","day":"01","intvolume":" 6","status":"public","date_created":"2018-12-11T12:06:42Z","extern":1,"volume":6,"page":"407 - 422","acknowledgement":"Center for Discrete Mathematics and Theoretical Computer Science (DIMACS), a National Science Foundation Science and Technology Center under NSF Grant STC 88-09648, National Science Foundation under Grant CCR-8714565.","publist_id":"2062","publisher":"Springer","issue":"1","date_updated":"2019-04-26T07:22:39Z","citation":{"chicago":"Agarwal, Pankaj, Herbert Edelsbrunner, Otfried Schwarzkopf, and Emo Welzl. “Euclidean Minimum Spanning Trees and Bichromatic Closest Pairs.” *Discrete & Computational Geometry* 6, no. 1 (1991): 407–22. https://doi.org/10.1007/BF02574698.","short":"P.
