• A nested family of k-total effective rewards for positional games 

      [OWP-2015-21] Boros, Endre; Elbassioni, Khaled; Gurvich, Vladimir; Makino, Kazuhisa (Mathematisches Forschungsinstitut Oberwolfach, 2015)
      We consider Gillette's two-person zero-sum stochastic games with perfect information. For each kZ+ we introduce an effective reward function, called k-total. For k=0 and 1 this function is known ...
    • A potential reduction algorithm for two-person zero-sum mean payoff stochastic games 

      [OWP-2015-19] Boros, Endre; Elbassioni, Khaled; Gurvich, Vladimir; Makino, Kazuhisa (Mathematisches Forschungsinstitut Oberwolfach, 2015)
      We suggest a new algorithm for two-person zero-sum undiscounted stochastic games focusing on stationary strategies. Given a positive real ϵ, let us call a stochastic game ϵ-ergodic, if its values from any ...
