A disjoint set structure supports: MAKE−SET(X):MAKE−SET(X):Creates a new Set with only element X and representative X. FIND(X):FIND(X):Returns the representative of the set to which X belongs. UNION(X,Y):UNION(X,Y):Unites the sets containing the elements X and Y into a sing...
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...
A disjoint set has no common element between them. For example, if there are two sets, A = {x, y} and B = {p, q}. As we can see that there are no common elements between the sets. We can take the intersection of two sets. A?B=?.A?B=?. Therefore, the intersection of two...

Following are the time complexities of disjoint set operations: Find(x):O(log n) where n is the number of elements. Union(x, y):O(log n) where n is the number of elements. MakeSet(x):O(1) Following are the applications of disjoint set data structure: ...

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。

The key idea is to first triangulate the original linear systems. The maximum component (MC)...
