Existing oblivious routing schemes with polylogarithmic competitive ratio for general networks are tree-based, in the sense that routing is performed according to a convex combination of trees. However, this restriction to trees leads to a construction that has time quadratic in the size of the network and does not parallelize well. \r\nIn this paper we study oblivious routing schemes based on electrical routing. In particular, we show that general networks with n vertices and m edges admit a routing scheme that has competitive ratio O(log² n) and consists of a convex combination of only O(√m) electrical routings. This immediately leads to an improved construction algorithm with time Õ(m^{3/2}) that can also be implemented in parallel with Õ(√m) depth.","lang":"eng"}],"oa":1,"_id":"15008","file":[{"checksum":"b89716aae6a5599f187897e39de1e53a","file_name":"2024_LIPICs_Goranci.pdf","content_type":"application/pdf","file_id":"15030","relation":"main_file","access_level":"open_access","creator":"dernst","success":1,"date_updated":"2024-02-26T10:10:48Z","file_size":1054754,"date_created":"2024-02-26T10:10:48Z"}],"status":"public","conference":{"end_date":"2024-02-02","location":"Berkeley, CA, United States","name":"ITCS: Innovations in Theoretical Computer Science Conference","start_date":"2024-01-30"},"date_updated":"2024-02-26T10:12:19Z","type":"conference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"grant_number":"101019564","call_identifier":"H2020","_id":"bd9ca328-d553-11ed-ba76-dc4f890cfe62","name":"The design and evaluation of modern fully dynamic data structures"},{"grant_number":"Z00422","_id":"34def286-11ca-11ed-8bc3-da5948e1613c","name":"Wittgenstein Award - Monika Henzinger"},{"grant_number":"I05982","name":"Static and Dynamic Hierarchical Graph Decompositions","_id":"bda196b2-d553-11ed-ba76-8e8ee6c21103"},{"grant_number":"P33775 ","_id":"bd9e3a2e-d553-11ed-ba76-8aa684ce17fe","name":"Fast Algorithms for a Reactive Network Layer"}],"oa_version":"Published Version","doi":"10.4230/LIPIcs.ITCS.2024.55","department":[{"_id":"MoHe"}],"ec_funded":1,"acknowledgement":"Monika Henzinger and A.
