pygambit.gambit.Infoset

class pygambit.gambit.Infoset

An information set in a Game.

An information set belonging to a personal player is a decision: the point at which that player chooses an action, and so the object of potential optimisation. An information set belonging to the chance player is instead called an event: its probability distribution over actions is exogenously specified, not chosen.
