优惠券收藏家的兄弟

The Coupon Collector's Brother

Vassilis G. Papanicolaou, Aristides V. Doumas

摘要:

收集者问题的一个流行变体如下:假设有$N$不同类型的优惠券具有相同的发生概率。有一个主要的收藏家谁收集优惠券。当她得到一个“双”,她给她的弟弟。因此,当主要收藏家完成她的收藏时,她哥哥的专辑仍然有$U_N$空白的空间。我们证明了,作为$N \to \infty$,$U_N/\ln N$的极限分布是指数的参数$1$。

英文摘要:

A popular variant of the collector's problem is the following: Assume there are $N$ different types of coupons with equal occurring probabilities. There is one main collector who collects coupons. When she gets a "double," she gives it to her younger brother. Hence, when the main collector completes her collection, her brother's album will still have, say, $U_N$ empty spaces. We show that, as $N \to \infty$, the limiting distribution of $U_N/\ln N$ is exponential with parameter $1$.
