1.Disjoint-set data structure2024-10-25 收起 并查集优化一:优化查找(get) 查找的优化是路径压缩,大大提高了优化效率我们可以看到,我们每次get一个x,它都会遍历它的父节点,若我们重复get,则他会重复遍历,这大大降低了效率。如果我们可以在他返回的时候将他路径上的每个节点的父节点全部改为根节点,则下一次查找时
Following is code for implementing disjoint set using array:C C++ Java Python Open Compiler #include <stdio.h> #include <stdlib.h> // Disjoint set data structure struct DisjointSet{ int *parent; int n; }; // Create a new set with element x void MakeSet(struct DisjointSet *ds, int ...
模板- 数据结构 - 并查集 / Disjoint Set 并查集的英文名理论上是 disjoint-set data structure (also called union–find data structure or merge–find set) 。所以说“并查集”这个词的来源,是其第二个和第三个英文名。 确定两个元素属于同一个集合需要Find找出他们的集合的代表元素再比较。 返回顶部 路径压...
Disjoint sets can be used for a number of math problems but specifically in data structures. In set theory, disjoint sets are two sets which do not share any common observations. In other words, if we take the intersection of two sets and the resulting set is an empty set then the sets...
可用CreateDataStructure创建新的"DisjointSet": In[1]:= Out[1]= 开始时没有元素,也没有子集: In[2]:= Out[2]= 插入两个元素;分别归入自己的子集: In[3]:= Out[3]= 统合子集: In[4]:= Out[4]= 再添加两个元素并统合;现在有两个子集: ...

disjoint-set data structure (DSDS)sparse linear systemstructured Gaussian elimination (SGE)triangulationStructured Gaussian elimination (SGE) is a class of methods for efficiently solving sparse linear systems. The key idea is to first triangulate the original linear systems. The maximum component (MC)...
First of all: a disjoint-set data structure is a structure that maintains a collection S1, S2, S3, …, Sn of dynamic disjoint sets. Two sets are disjoint if their intersection is null. For example set {1, 2, 3} and set {1, 5, 6} aren’t disjoint because they have in common {...

并查集 ( Disjoint-Set or Union-Find data structure ) 什么是并查集 1.将n个不重复的元素( distinct elements ), 分配到几个不相交集合( disjoint sets )的应用。 换句话说,一个不相交的集合(disjoint sets)是一组集合,其中任何项都不能出现在一个以上的集合中。
