These are games usually played between two players on a given graph, where the players keep moving a token along the edges according to pre-determined rules (turn-based, concurrent, etc.), and the winner is decided based on the infinite path (aka play) traversed by the token from a given initial position. In bidding games, the players initially get some monetary budgets which they need to use to bid for the privilege of moving the token at each step. Each round of bidding affects the players' available budgets, which is the only form of update that the budgets experience. We introduce bidding games with charging where the players can additionally improve their budgets during the game by collecting vertex-dependent monetary rewards, aka the \"charges.\" Unlike traditional bidding games (where all charges are zero), bidding games with charging allow non-trivial recurrent behaviors. For example, a reachability objective may require multiple detours to vertices with high charges to earn additional budget. We show that, nonetheless, the central property of traditional bidding games generalizes to bidding games with charging: For each vertex there exists a threshold ratio, which is the necessary and sufficient fraction of the total budget for winning the game from that vertex. While the thresholds of traditional bidding games correspond to unique fixed points of linear systems of equations, in games with charging, these fixed points are no longer unique. This significantly complicates the proof of existence and the algorithmic computation of thresholds for infinite-duration objectives. We also provide the lower complexity bounds for computing thresholds for Rabin and Streett objectives, which are the first known lower bounds in any form of bidding games (with or without charging), and we solve the following repair problem for safety and reachability games that have unsatisfiable objectives: Can we distribute a given amount of charge to the players in a way such that the objective can be satisfied?"}],"file":[{"file_id":"18083","creator":"dernst","access_level":"open_access","file_size":854430,"relation":"main_file","file_name":"2024_LIPICS_Avni.pdf","checksum":"cb6f2254b84922cd7bf224f550b73f4a","date_created":"2024-09-17T09:35:03Z","success":1,"date_updated":"2024-09-17T09:35:03Z","content_type":"application/pdf"}],"tmp":{"short":"CC BY (4.0)","image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"type":"conference","corr_author":"1","publication_identifier":{"isbn":["9783959773393"],"issn":["1868-8969"]},"_id":"18066","quality_controlled":"1","project":[{"name":"Vigilant Algorithmic Monitoring of Software","grant_number":"101020093","call_identifier":"H2020","_id":"62781420-2b32-11ec-9570-8d9b63373d4d"},{"_id":"0599E47C-7A3F-11EA-A408-12923DDC885E","name":"Formal Methods for Stochastic Models: Algorithms and Applications","call_identifier":"H2020","grant_number":"863818"}],"alternative_title":["LIPIcs"],"doi":"10.4230/LIPIcs.CONCUR.2024.8","citation":{"chicago":"Avni, Guy, Ehsan Kafshdar Goharshady, Thomas A Henzinger, and Kaushik Mallik. “Bidding Games with Charging.” In <i>35th International Conference on Concurrency Theory</i>, Vol. 311.
