Coupons collecting with or without replacement, and with multipurpose coupons

Marcel Wild, Svante Janson, Stephan Wagner, Dirk Laurie

摘要:

经典的优惠券收集者问题(CCP)被推广到某种程度上,每个优惠券服务于某些“目的”。只使用基本的概率论。相反,中心块是一种算法,它有效地计数集合系统的所有$k$元素横截。

英文摘要:

The classic Coupon-Collector Problem (CCP) is generalized to the extent that each coupons serves certain "purposes". Only basic probability theory is used. Centerpiece rather is an algorithm that efficiently counts all $k$-element transversals of a set system.
