Set-based symbolic algorithms use basic set operations and one-step predecessor operations on the implicit description of games, rather than the explicit representation. The significance of symbolic algorithms is that they provide scalable algorithms for large finite-state systems, as well as for infinite-state systems with finite quotient. Consider parity games on graphs with n vertices and parity conditions with d priorities. While there is a rich literature of explicit algorithms for parity games, the main results for set-based symbolic algorithms are as follows: (a) the basic algorithm that requires O(nd) symbolic operations and O(d) symbolic space; and (b) an improved algorithm that requires O(nd/3+1) symbolic operations and O(n) symbolic space. In this work, our contributions are as follows: (1) We present a black-box set-based symbolic algorithm based on the explicit progress measure algorithm. Two important consequences of our algorithm are as follows: (a) a set-based symbolic algorithm for parity games that requires quasi-polynomially many symbolic operations and O(n) symbolic space; and (b) any future improvement in progress measure based explicit algorithms immediately imply an efficiency improvement in our set-based symbolic algorithm for parity games. (2) We present a set-based symbolic algorithm that requires quasi-polynomially many symbolic operations and O(d · log n) symbolic space. Moreover, for the important special case of d ≤ log n, our algorithm requires only polynomially many symbolic operations and poly-logarithmic symbolic space."}],"publication_status":"published","publication":"22nd International Conference on Logic for Programming, Artificial Intelligence and Reasoning","type":"conference","has_accepted_license":"1","date_updated":"2022-07-29T09:24:31Z","volume":57,"publication_identifier":{"issn":["2398-7340"]},"day":"23","publisher":"EasyChair","year":"2018","ec_funded":1,"date_published":"2018-10-23T00:00:00Z","quality_controlled":"1","scopus_import":"1","title":"Quasipolynomial set-based symbolic algorithms for parity games","oa_version":"Published Version","language":[{"iso":"eng"}],"file":[{"date_updated":"2022-05-17T07:51:08Z","file_id":"11392","creator":"dernst","checksum":"1229aa8640bd6db610c85decf2265480","date_created":"2022-05-17T07:51:08Z","success":1,"file_name":"2018_EPiCs_Chatterjee.pdf","relation":"main_file","access_level":"open_access","file_size":720893,"content_type":"application/pdf"}],"intvolume":"        57"}
