Imperfect recall

WitrynaThe idea of perfect recall is that a player has perfect recall if, at each of his information sets he remembers what he knew and what he did in the past. This idea was introduced and formally deﬁned by Kuhn (1950, 1953). http://www.eecs.harvard.edu/cs286r/courses/fall12/presentations/lecture3.pdf

Witrynarecall and facilitated the development of extensive game theory. Almost the entire literature on extensive games invokes the perfect recall assumption and often invokes in some form or another Kuhn’s Theorem. In extensive games with unawareness, the notion of mixed strategy is even less compelling. A player may not be aware of all actions ex ... WitrynaSummary. In a game of imperfect recall, a sequential equilibrium may not be a Nash equilibrium, and a perfect equilibrium may not be a sequential equilibrium. Sufficiency conditions weaker than perfect recall are given to ensure the standard relationships hold between perfect equilibrium, sequential equilibrium and Nash equilibrium.
