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.","lang":"eng"}],"day":"10","quality_controlled":"1","article_type":"original","volume":21,"language":[{"iso":"eng"}],"publist_id":"2009","author":[{"first_name":"Herbert","orcid":"0000-0002-9823-6833","full_name":"Edelsbrunner, Herbert","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","last_name":"Edelsbrunner"},{"full_name":"Maurer, Hermann","first_name":"Hermann","last_name":"Maurer"}],"page":"39 - 47","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","publication":"Information Processing Letters","date_created":"2018-12-11T12:07:00Z","year":"1985","date_published":"1985-07-10T00:00:00Z","article_processing_charge":"No","doi":"10.1016/0020-0190(85)90107-3","publication_identifier":{"eissn":["1872-6119"],"issn":["0020-0190"]},"_id":"4111","title":"Finding extreme-points in 3-dimensions and solving the post-office problem in the plane","month":"07","issue":"1","oa_version":"None","citation":{"ieee":"H.
