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...

Connected component labeling (alternatively connected component analysis) is an algorithmic application of graph theory, where subsets of connected components are uniquely labeled based on a given heuristic. Connected component labeling is not to be confused with segmentation. Connected component labeling is...

Let G, a, b, and n be as in Theorem 1. We choose F be an [a,b]-factor of G with ω(F) maximum. Let C1,C2,…,Cm be the components of F, and we denote V1=V(C1),V2=V(C2),…,Vm=V(Cm). Then V(G) is the disjoint union V1∪V2∪⋯∪Vm. Here we define some te...
On Finding the Strong Components in a Directed Graph We present two improved versions of Tarjan's algorithm for finding the strongly connected (or strong, for short) components in a directed graph. The original algorithm of Tarjan can be considered to contain two (interleaved) traversals o... ...
The following is a formal definition of connected components in graph theory context. Let G=(V, E) be an undirected graph where V is the set of vertices and E is the set of edges. C=(C1, C2, . . . , Cn) is the set of disjoint connected components in this graph where (C1∪C2...
