关于计算k-水平和参数生成树中峰值的注记

Notes on computing peaks in k-levels and parametric spanning trees

Naoki Katoh, Takeshi Tokuyama

摘要:

我们给出了一个算法来计算在$O(n \log n) + \tilde{O}((kn)^{2/3})$时间的$n$线的排列的$k$ -水平的所有局部峰值。我们还可以在$O(n \log ^2 n) + \tilde{O}((τn)^{2/3})$时间中找到$τ$最大峰。此外,我们考虑了参数最小生成树中的最长边(换句话说,连通性的瓶颈边),并给出了一个算法来计算参数值(在给定的区间内)最大化/最小化MST中的最长边的长度。时间复杂度为$\tilde{O}(n^{8/7}k^{1/7} + n k^{1/3})$

英文摘要:

We give an algorithm to compute all the local peaks in the $k$-level of an arrangement of $n$ lines in $O(n \log n) + \tilde{O}((kn)^{2/3})$ time. We can also find $τ$ largest peaks in $O(n \log ^2 n) + \tilde{O}((τn)^{2/3})$ time. Moreover, we consider the longest edge in a parametric minimum spanning tree (in other words, a bottleneck edge for connectivity), and give an algorithm to compute the parameter value (within a given interval) maximizing/minimizing the length of the longest edge in MST. The time complexity is $\tilde{O}(n^{8/7}k^{1/7} + n k^{1/3})$
