This improves upon the previous O(log Δ)-time algorithm by Bhattacharya et al. (SODA 2018). Our algorithm uses an approach based on assigning random ranks to vertices and does not need to maintain a hierarchical graph decomposition. We show that our result does not only have optimal running time, but is also optimal in the sense that already deciding whether a Δ-coloring exists in a dynamically changing graph with maximum degree at most Δ takes Ω(log n) time per operation.","lang":"eng"}],"language":[{"iso":"eng"}],"external_id":{"arxiv":["1907.04745"]},"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"04","date_updated":"2023-02-14T10:03:43Z","volume":154,"extern":"1","title":"Constant-time dynamic (Δ+1)-coloring","date_created":"2022-08-12T07:53:05Z","quality_controlled":"1","oa_version":"Published Version","conference":{"end_date":"2020-03-13","name":"STACS: Symposium on Theoretical Aspects of Computer Science","start_date":"2020-03-10","location":"Montpellier, France"},"article_processing_charge":"No","publication":"37th International Symposium on Theoretical Aspects of Computer Science","status":"public","publisher":"Schloss Dagstuhl - Leibniz-Zentrum für Informatik","publication_identifier":{"issn":["1868-8969"],"isbn":["9783959771405"]},"type":"conference","intvolume":"       154","author":[{"first_name":"Monika H","last_name":"Henzinger","full_name":"Henzinger, Monika H","orcid":"0000-0002-5008-6530","id":"540c9bbd-f2de-11ec-812d-d04a5be85630"},{"full_name":"Peng, Pan","last_name":"Peng","first_name":"Pan"}],"doi":"10.4230/LIPIcs.STACS.2020.53","alternative_title":["LIPIcs"]}
