We show that this measure is related to the average winding number of its Gauss map. Using this relationship, we give an algorithm for computing the writhing number for a polygonal knot with n edges in time roughly proportional to n(1.6). We also implement a different, simple algorithm and provide experimental evidence for its practical efficiency.","lang":"eng"}],"date_created":"2018-12-11T12:06:23Z","conference":{"name":"SODA: Symposium on Discrete Algorithms","end_date":"2002-01-08","start_date":"2002-01-06","location":"San Francisco, CA, USA"},"scopus_import":"1","article_processing_charge":"No","page":"791 - 799","status":"public","main_file_link":[{"url":"https://dl.acm.org/doi/10.5555/545381.545485"}],"day":"01","publication_status":"published","publication":"Proceedings of the 13th annual ACM-SIAM symposium on Discrete algorithms","date_updated":"2023-06-07T13:50:04Z","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","month":"01","title":"Computing the writhing number of a polygonal knot","publisher":"SIAM"}
