This paper considers the condition of perfect recall for the class of arbitrarily large discrete extensive form games. The known definitions of perfect recall are shown to be equivalent even beyond finite games. Further, a qualitatively new characterization in terms of choices is obtained. In particular, an extensive form game satisfies perfect recall if and only if the set of choices, viewed a...

Two experiments examined whether people expecting recall are, compared with people expecting recognition, more likely to form associations between semantically related words in a list of to-be-remembered words. People were induced to expect either a recall or a recognition test on a critical list that included three conditions of semantic organization. Words in the unrelated (U) condition were ...

We consider finding maximin strategies and equilibria of explicitly given extensive form games with imperfect information but with no moves of chance. We show: 1. A maximin pure strategy for a two-player extensive form game with perfect recall and no moves of chance can be found in time linear in the size of the game tree. In contrast, it is known that this problem is NP-hard for games with cha...

Extensive-form games with imperfect recall are an important model of dynamic games where the players are allowed to forget previously known information. Often, imperfect recall games are the result of an abstraction algorithm that simplifies a large game with perfect recall. Unfortunately, solving an imperfect recall game has fundamental problems since a Nash equilibrium does not have to exist....

background and objective: identifying the details of the injurious effects of alcohol seems to be decisive in nowadays with growing abuse of the substance. this study mainly aimed to assess the adverse effects of ethanol on the recalling of information in the wistar rats. materials and methods: male wistar rats (pasteur institute of iran) were evaluated using the novelty seeking behavior based ...
