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}.","lang":"eng"}],"article_processing_charge":"No","status":"public","page":"407 - 422","publication_status":"published","date_published":"1991-12-01T00:00:00Z","publisher":"Springer","type":"journal_article"}
