The solution takes O(n) space and O(log n) time for a query. By use of geometric transforms, the post-office problem for a finite set of points in two dimensions and certain two-dimensional point location problems are reduced to the former problem and thus also optimally solved."}],"publication_identifier":{"issn":["0020-0190"],"eissn":["1872-6119"]},"month":"07","doi":"10.1016/0020-0190(85)90107-3"}
