Reachability for Branching Concurrent Stochastic Games.

Abstract

We give polynomial time algorithms for deciding almost-sure and limit-sure reachability in Branching Concurrent Stochastic Games (BCSGs). These are a class of infinite-state imperfect-information stochastic games that generalize both finite-state concurrent stochastic reachability games, as well as branching simple stochastic reachability games.
