{"abstract":[{"lang":"eng","text":"We consider concurrent mean-payoff games, a very well-studied class of two-player (player 1 vs player 2) zero-sum games on finite-state graphs where every transition is assigned a reward between 0 and 1, and the payoff function is the long-run average of the rewards. The value is the maximal expected payoff that player 1 can guarantee against all strategies of player 2. We consider the computation of the set of states with value 1 under finite-memory strategies for player 1, and our main results for the problem are as follows: (1) we present a polynomial-time algorithm; (2) we show that whenever there is a finite-memory strategy, there is a stationary strategy that does not need memory at all; and (3) we present an optimal bound (which is double exponential) on the patience of stationary strategies (where patience of a distribution is the inverse of the smallest positive probability and represents a complexity measure of a stationary strategy)."}],"day":"01","type":"conference","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"SIAM","intvolume":"      2015","title":"The value 1 problem under finite-memory strategies for concurrent mean-payoff games","quality_controlled":"1","ec_funded":1,"article_processing_charge":"No","citation":{"apa":"Chatterjee, K., &#38; Ibsen-Jensen, R.
