In mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to separate the remaining nodes into two or more isolated subgraphs. It is closely related to the theory of network flow … See more In an undirected graph G, two vertices u and v are called connected if G contains a path from u to v. Otherwise, they are called disconnected. If the two vertices are additionally connected by a path of length 1, i.e. by a single … See more A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected … See more The problem of determining whether two vertices in a graph are connected can be solved efficiently using a search algorithm, such as See more • The vertex-connectivity of a graph is less than or equal to its edge-connectivity.
