Tarjan’s off-line lowest common ancestors algorithm 之间的其他关系。并查集的实现有两种[7],quick-find 以及quick-union,较为常用的方法是基于quick-union ,而 quick-union 有两个维度的改进,&ldquo... LCA中的 union 操作,是在处理完一个节点时,将其与已经处理过的其它同一层的子节点所代表的等价类进行...
So, the approach above cannot decrease the union operation time complexity, rather, it increases the find operation time complexity. If we have a closer look, we can find the reason why quick-union approach is not performing well is because the height of the tree could be very tall. So, ...

原文链接 在计算机科学(Computer Science,CS)领域,算法(Algorithm)是描述一种有限、确定、有效,并且适合用计算机语言来实现的解决问题的方法,它是CS领域的基础与核心。 这里先通过一个动态连通性问题,来了解设计、分析算法的基本过程。 动态连通性 问题描述 动态连通性问题的描述如下:问题的输入是一系列的整数对,每个...
本文主要介绍解决动态连通性一类问题的一种算法,使用到了一种叫做并查集的数据结构,称为Union-Find。 更多的信息可以参考Algorithms 一书的Section 1.5,实际上本文也就是基于它的一篇读后感吧。 原文中更多的是给出一些结论,我尝试给出一些思路上的过程,即为什么要使用这个方法,而不是别的什么方法。我觉得这个可能更加...
记得我之前在讲 图论算法基础 时说图论相关的算法不会经常考,但最近被打脸了,因为一些读者和我反馈近期求职面试涉及很多图论相关的算法,可能是因为环境不好所以算法这块更卷了吧。
Union-Find Algorithm Example Let's walk through an example of the Union-Find algorithm. Suppose we have a set of 7 elements: {0, 1, 2, 3, 4, 5, 6}. Initially, each element belongs to its own set. We can represent each set as a tree, with each node representing an element in ...
Union-Find Algorithm Union-Find Algrithm is used to check whether two components are connected or not. Examples: By using the graph, we can easily find whether two components are connected or not, if there is no such graph, how do we know whether two components are connected or not?
