Witryna1 sty 2024 · Games of imperfect recall are a class of extensive games with imperfect information in which players do not always remember the experience they lived … Witryna14 sie 2013 · In particular, we use a recent metric for abstraction quality and examine imperfect recall abstractions, in which agents "forget" previously observed information to focus the abstraction effort on more recent and relevant state information. We present experimental results in the domain of Texas hold'em poker that validate the use of ...

Did you know?
WitrynaHowever, imperfect-recall abstrac-tions are poorly understood, and only weak algorithm-speci c guarantees on solution quality are known. We develop the rst general, algorithm-agnostic, solution quality guarantees for Nash equilibria and approximate self-trembling equilibria computed in imperfect-recall abstractions, 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).

Capital … Witrynaimperfect-recall abstractions, when implemented in the original (perfect-recall) game. Our results are for a class of games that generalizes the only previously known class of imperfect-recall abstractions where any results had been obtained.

Witryna16 lut 2024 · The reliability of recall is important for epidemiological studies: imperfect, but unbiased, recall could weaken potential associations with health outcomes; biased recall, for example, differing by diseased/not diseased or exposed/not exposed individuals, could either exaggerate or dilute estimated risks ( Pearce et al., 2007 ).

However, it resolves the time-consistency paradox in decision problems with imperfect recall, and as we prove in this paper, it allows to recover the two major equilibrium properties aforementioned in games with imperfect recall.

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. high wine tilburg
