论文摘要
我们描述了一个数据结构,该数据结构可以维护其笛卡尔坐标给出的动态集,并维护两个坐标订购级内等级的乘积,在时间$ o(\ sqrt {n \ log n})中,每个更新每个更新。
We describe a data structure that can maintain a dynamic set of points given by their Cartesian coordinates, and maintain the point whose product of ranks within the two coordinate orderings is minimum or maximum, in time $O(\sqrt{n\log n})$ per update.
