In graph theory, a connected component (or justcomponent) of an undirected graph is a subgraph in which any two vertices are connected to each other by paths, and which is connected to no additional vertices in the supergraph. Connected Components即连通域,适用于无向图。一个连通域,指的是这...

and which is connected to no additional vertices. For example, the graph shown in the illustration on the right has three connected components. A graph that is itself connected has exactly one connected component, consisting of the whole graph. ...
Given n nodes labeled from 0 to n - 1 and a list of undirected edges (each edge is a pair of nodes), write a function to find the number of connected components in an undirected graph. Example 1: 0 3 | | 1 --- 2 4 Given n = 5 and edges = [[0, 1], [1, 2], [3,...
An efficient method for finding a minimal feedback arc set in directed graphs After partitioning the graph into strongly and bi-connected components, depth-first search traversing is performed on each component. Reordering is done so ... S Park,SB Akers - IEEE International Symposium on Circuits...
A strongly connected component is the portion of a directed graph in which there is a path from each vertex to another vertex. It is applicable only on a directed graph. For example: Let us take the graph below. Initial graph The strongly connected components of the above graph are: ...

We present an algorithm to maintain the connected components of a graph that arrives as an infinite stream of edges. We formalize the algorithm on X-stream, a new parallel theoretical computational model for infinite streams. Connectivity-related queries, including component spanning trees, are suppor...
