In this paper we consider good drawings, i.e., we require that\r\nany two edges have at most one common point which can be a common vertex or a\r\ncrossing. Our main result is that there is a polynomial-time algorithm to compute an\r\n8-approximation of the bundled crossing number of a good drawing with no toothed\r\nhole. In general the number of toothed holes has to be added to the 8-approximation.\r\nIn the special case of circular drawings the approximation factor is 8, this improves\r\nupon the 10-approximation of Fink et al. [14]. Our approach also works with the same\r\napproximation factor for families of pseudosegments, i.e., curves intersecting at most\r\nonce. We also show how to compute a 9/2-approximation when the intersection graph of\r\nthe pseudosegments is bipartite and has no toothed hole."}],"volume":27,"date_updated":"2024-10-09T21:06:15Z","file":[{"success":1,"file_name":"2023_JourGraphAlgorithms_Arroyo.pdf","date_updated":"2023-08-07T08:00:48Z","file_size":865774,"creator":"dernst","checksum":"9c30d2b8e324cc1c904f2aeec92013a3","relation":"main_file","date_created":"2023-08-07T08:00:48Z","file_id":"13979","access_level":"open_access","content_type":"application/pdf"}]}
