The class of ω-regular languages provides a robust specification formalism for the desired properties of reactive systems. In the classical infinitary formulation of the liveness part of an ω-regular specification, a \"good\" event must happen eventually without any bound between the good events. A stronger notion of liveness is bounded liveness, which requires that good events happen within d transitions. Given a graph or a game graph with n vertices, m edges, and a bounded liveness objective, the previous best-known algorithmic bounds are as follows: (i) O(dm) for graphs, which in the worst-case is O(n³); and (ii) O(n² d²) for games on graphs. Our main contributions improve these long-standing algorithmic bounds. For graphs we present: (i) a randomized algorithm with one-sided error with running time O(n^{2.5} log n) for the bounded liveness objectives; and (ii) a deterministic linear-time algorithm for the complement of bounded liveness objectives. For games on graphs, we present an O(n² d) time algorithm for the bounded liveness objectives."}],"file_date_updated":"2021-10-01T08:49:26Z","doi":"10.4230/LIPIcs.ICALP.2021.124","day":"02","author":[{"id":"2E5DCA20-F248-11E8-B48F-1D18A9856A87","full_name":"Chatterjee, Krishnendu","orcid":"0000-0002-4561-241X","first_name":"Krishnendu","last_name":"Chatterjee"},{"orcid":"0000-0002-5008-6530","last_name":"Henzinger","first_name":"Monika H","id":"540c9bbd-f2de-11ec-812d-d04a5be85630","full_name":"Henzinger, Monika H"},{"full_name":"Kale, Sagar Sudhir","last_name":"Kale","first_name":"Sagar Sudhir"},{"first_name":"Alexander","last_name":"Svozil","full_name":"Svozil, Alexander"}],"quality_controlled":"1","volume":198,"file":[{"success":1,"creator":"cchlebak","file_id":"10062","file_size":854576,"date_created":"2021-10-01T08:49:26Z","file_name":"2021_LIPIcs_Chatterjee.pdf","content_type":"application/pdf","checksum":"5a3fed8dbba8c088cbeac1e24cc10bc5","date_updated":"2021-10-01T08:49:26Z","access_level":"open_access","relation":"main_file"}],"title":"Faster algorithms for bounded liveness in graphs and game graphs","ec_funded":1,"intvolume":"       198","acknowledgement":"Krishnendu Chatterjee: Supported by the ERC CoG 863818 (ForM-SMArt).
