Arena-Independent Finite-Memory Determinacy in Stochastic Games

no code implementations19 Feb 2021 Patricia Bouyer, Youssouf Oualhadj, Mickael Randour, Pierre Vandenhove

Second, we show that we can reduce the study of objectives for which pure AIFM strategies suffice in two-player stochastic games to the easier study of one-player stochastic games (i. e., Markov decision processes).

Games Where You Can Play Optimally with Arena-Independent Finite Memory

no code implementations12 Jan 2020 Patricia Bouyer, Stéphane Le Roux, Youssouf Oualhadj, Mickael Randour, Pierre Vandenhove

In 2005, Gimbert and Zielonka provided a complete characterization of preference relations (a formal framework to model specifications and game objectives) that admit memoryless optimal strategies for both players.

Life is Random, Time is Not: Markov Decision Processes with Window Objectives

no code implementations11 Jan 2019 Thomas Brihaye, Florent Delgrange, Youssouf Oualhadj, Mickael Randour

The window mechanism was introduced by Chatterjee et al. to strengthen classical game objectives with time bounds.

Threshold Constraints with Guarantees for Parity Objectives in Markov Decision Processes

no code implementations17 Feb 2017 Raphaël Berthon, Mickael Randour, Jean-François Raskin

We establish that, for all variants of this problem, deciding the existence of a strategy lies in ${\sf NP} \cap {\sf coNP}$, the same complexity class as classical parity games.
