构造层次重叠图的线性时间算法
A Linear Time Algorithm for Constructing Hierarchical Overlap Graphs
摘要:
分层重叠图(HOG)是一个图,编码重叠从一个给定的集合P的n个字符串,重叠图。一个最著名的算法构造HOG在O(||P||时间复杂度为O(||P||)空间,其中||P||是P中字符串长度之和。本文给出了一个构造O(||P||)时间和空间。因此,HOG的构造时间和空间优于重叠图的构造时间和空间,重叠图的构造时间和空间为O(||P|| + n^2)。
英文摘要:
The hierarchical overlap graph (HOG) is a graph that encodes overlaps from a given set P of n strings, as the overlap graph does. A best known algorithm constructs HOG in O(||P|| log n) time and O(||P||) space, where ||P|| is the sum of lengths of the strings in P. In this paper we present a new algorithm to construct HOG in O(||P||) time and space. Hence, the construction time and space of HOG are better than those of the overlap graph, which are O(||P|| + n^2).
