Turn-based games model asynchronous interaction between the players (the system and its environment) by interleaving their moves. Concurrent games model synchronous interaction: the players always move simultaneously. Infinitary winning criteria are considered: Büchi, co-Büchi, and more general parity conditions. A generalization of determinacy for parity games to concurrent parity games demands probabilistic (mixed) strategies: either player 1 has a mixed strategy to win with probability 1 (almost-sure winning), or player 2 has a mixed strategy to win with positive probability.\r\nThis work provides efficient reductions of concurrent probabilistic Büchi and co-Büchi games to turn-based games with Büchi condition and parity winning condition with three priorities, respectively. From a theoretical point of view, the latter reduction shows that one can trade the probabilistic nature of almost-sure winning for a more general parity (fairness) condition. The reductions improve understanding of concurrent games and provide an alternative simple proof of determinacy of concurrent Büchi and co-Büchi games. From a practical point of view, the reductions turn solvers of turn-based games into solvers of concurrent probabilistic games. Thus improvements in the well-studied algorithms for the former carry over immediately to the latter. In particular, a recent improvement in the complexity of solving turn-based parity games yields an improvement in time complexity of solving concurrent probabilistic co-Büchi games from cubic to quadratic.","lang":"eng"}],"oa_version":"None","date_created":"2018-12-11T12:08:46Z","user_id":"ea97e931-d5af-11eb-85d4-e6957dddbf17","publisher":"Springer","scopus_import":"1","title":"Trading probability for fairness","quality_controlled":"1","status":"public","alternative_title":["LNCS"],"doi":"10.1007/3-540-45793-3_20","page":"292 - 305","author":[{"last_name":"Jurdziński","first_name":"Marcin","full_name":"Jurdziński, Marcin"},{"full_name":"Kupferman, Orna","first_name":"Orna","last_name":"Kupferman"},{"first_name":"Thomas A","last_name":"Henzinger","full_name":"Henzinger, Thomas A","id":"40876CD8-F248-11E8-B48F-1D18A9856A87","orcid":"0000−0002−2985−7724"}],"publication":"Proceedings of the 16th International Workshop on Computer Science Logic","publication_identifier":{"isbn":["9783540442400"]},"conference":{"name":"CSL: Computer Science Logic","location":"Edinburgh, Scotland"},"citation":{"mla":"Jurdziński, Marcin, et al. “Trading Probability for Fairness.” <i>Proceedings of the 16th International Workshop on Computer Science Logic</i>, vol. 2471, Springer, 2002, pp. 292–305, doi:<a href=\"https://doi.org/10.1007/3-540-45793-3_20\">10.1007/3-540-45793-3_20</a>.","ieee":"M.
