本文讨论了在概率数据条件下计算一组点的最小封闭球的问题。在我们的设置中,n个点中的任何一个都可能不是或可能出现在有限多个位置中的一个,遵循其自己的离散概率分布。因此,目标被认为是一个随机变量,我们的目标是找到一个中心,根据它们的分布最小化到这些点的期望最大距离。我们在本文中提出的主要贡献是第一个多项式时间(1 + λ)逼近算法,用于扩展到流设置的概率最小封闭球问题。
This paper deals with computing the smallest enclosing ball of a set of points subject to probabilistic data. In our setting, any of the n points may not or may occur at one of finitely many locations, following its own discrete probability distribution. The objective is therefore considered to be a random variable and we aim at finding a center minimizing the expected maximum distance to the points according to their distributions. Our main contribution presented in this paper is the first polynomial time (1 + ϵ)-approximation algorithm for the probabilistic smallest enclosing ball problem with extensions to the streaming setting.
