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"}],"quality_controlled":"1","volume":21,"date_updated":"2022-01-31T12:49:12Z","year":"1985","publication_identifier":{"eissn":["1872-6119"],"issn":["0020-0190"]},"type":"journal_article","_id":"4111","scopus_import":"1","author":[{"last_name":"Edelsbrunner","id":"3FB178DA-F248-11E8-B48F-1D18A9856A87","first_name":"Herbert","full_name":"Edelsbrunner, Herbert","orcid":"0000-0002-9823-6833"},{"first_name":"Hermann","last_name":"Maurer","full_name":"Maurer, Hermann"}],"publication":"Information Processing Letters","publication_status":"published","day":"10","publisher":"Elsevier"}
