洗牌和伯努利-拉普拉斯瓮模型

Shuffling large decks of cards and the Bernoulli-Laplace urn model

Evita Nestoridi, Graham White

摘要:

在纸牌游戏中,在具有多副牌的赌场游戏中以及在密码学中,人们有时会面临以下问题:人类(与计算机相对)如何洗牌一副大牌?我们研究的程序是将甲板分成几个合理大小的桩,彻底洗牌,重新组合桩,做一些简单的确定性操作,例如切割,然后重复。这个过程也可以看作是一个广义的伯努利-拉普拉斯瓮模型。我们利用耦合变元和球函数理论导出了这些马尔可夫链混合时间的上界和下界。

英文摘要:

In card games, in casino games with multiple decks of cards and in cryptography, one is sometimes faced with the following problem: how can a human (as opposed to a computer) shuffle a large deck of cards? The procedure we study is to break the deck into several reasonably sized piles, shuffle each thoroughly, recombine the piles, do some simple deterministic operation, for instance a cut, and repeat. This process can also be seen as a generalised Bernoulli-Laplace urn model. We use coupling arguments and spherical function theory to derive upper and bounds on the mixing times of these Markov chains.
