Narendra-Shapiro (NS) algorithms are bandit-type algorithms that were introduced in the 1960s in view of applications to Psychology or clinical trials. The long time behavior of such algorithms has been studied in depth but it seems that few results exist in a non-asymptotic setting, which can be...

Definable zero-sum stochastic games involve a finite number of states and action sets, and reward and transition functions, that are definable in an o-minimal structure. Prominent examples of such games are finite, semi-algebraic, or globally subanalytic stochastic games. We prove that the Shapley...
