We address the following issues: 1. randomization at information sets; 2. consistent beliefs; 3. time … 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).
