The game proceeds by placing a token on a vertex of a graph, and allowing the players to move it to produce an infinite path, which determines the winner or payoff of the game. Traditionally, the players alternate turns in moving the token. In \"bidding games\", however, the players have budgets and in each turn, an auction (bidding) determines which player moves the token. So far, bidding games have only been studied as full-information games. In this work we initiate the study of partial-information bidding games: we study bidding games in which a player's initial budget is drawn from a known probability distribution. We show that while for some bidding mechanisms and objectives, it is straightforward to adapt the results from the full-information setting to the partial-information setting, for others, the analysis is significantly more challenging, requires new techniques, and gives rise to interesting results. Specifically, we study games with \"mean-payoff\" objectives in combination with \"poorman\" bidding. We construct optimal strategies for a partially-informed player who plays against a fully-informed adversary. We show that, somewhat surprisingly, the \"value\" under pure strategies does not necessarily exist in such games."}],"status":"public","conference":{"end_date":"2023-02-14","location":"Washington, DC, United States","name":"AAAI: Conference on Artificial Intelligence","start_date":"2023-02-07"},"_id":"14243","ec_funded":1,"acknowledgement":"This research was supported in part by ISF grant no.1679/21, by the ERC CoG 863818 (ForM-SMArt), and the European Union’s Horizon 2020 research and innovation programme under the Marie Skłodowska-Curie Grant Agreement No. 665385.","date_updated":"2023-09-05T08:37:00Z","type":"conference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","project":[{"name":"Formal Methods for Stochastic Models: Algorithms and Applications","_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","grant_number":"863818","call_identifier":"H2020"},{"grant_number":"665385","call_identifier":"H2020","_id":"2564DBCA-B435-11E9-9278-68D0E5697425","name":"International IST Doctoral Program"}],"doi":"10.1609/aaai.v37i5.25679","oa_version":"Published Version","department":[{"_id":"ToHe"},{"_id":"KrCh"}],"publication":"Proceedings of the 37th AAAI Conference on Artificial Intelligence","issue":"5","publication_status":"published","month":"06","date_created":"2023-08-27T22:01:18Z","external_id":{"arxiv":["2211.13626"]}}
