AI总结:

本文研究了一次书架洗牌后的猜牌游戏,分析了最优策略下的正确猜测数量分布,并推导了中心极限定理。

摘要:

我们考虑一个具有完整反馈的猜牌游戏。一个有n张牌的有序牌堆被书架洗牌一次。然后依次从洗牌后的牌堆中抽出一张牌。猜牌者进行猜测,直到牌堆中没有牌为止。我们对在最优策略下正确猜测数量的分布进行了分析。我们重新获得了之前推导出的期望值,并给出了完整分布的描述。我们还为当牌数n趋于无穷大时,正确猜测数量的中心极限定理提供了证明。此外,我们讨论了不平衡的偏置书架洗牌,并展示了如何扩展我们的分析,同时添加了完整的位矩阵。最后,对正确猜测数量进行了更深入的分析,区分了纯运气猜测和已证实正确的猜测。

英文摘要:

We consider a card guessing game with complete feedback. An ordered deck of $n$ cards labeled $1$ up to $n$ is shelf-shuffled exactly one time. One after the other a single card is drawn from the shuffled deck. The guesser makes has guess and the card is shown until no cards remain. We provide a distributional analysis of the number of correct guesses under the optimal strategy. We re-obtain the previously derived expectation and add a complete description of the distribution. We also obtain a central limit theorem for the number $n$ of cards tending to infinity. Furthermore, we discuss an unbalanced, biased shelf shuffle and show how to derive the extend our analysis, also adding the complete position matrix. Finally, a refined analysis of the number of correct guesses is carried out, distinguishing between pure luck guesses and certified correct guesses.
