WebJan 14, 2024 · A directed graph (or digraph) is a set of vertices and a collection of directed edges that each connects an ordered pair of vertices. We say that a directed edge …
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 edge, the vertices are called adjacent. A graph is said to be connected if every pair of … See more 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 … 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 breadth-first search. More generally, it is easy … See more • The vertex-connectivity of a graph is less than or equal to its edge-connectivity. That is, κ(G) ≤ λ(G). Both are less than or equal to the minimum degree of the graph, since deleting all … See more One of the most important facts about connectivity in graphs is Menger's theorem, which characterizes the connectivity and edge-connectivity of a graph in terms of the number of … See more • The vertex- and edge-connectivities of a disconnected graph are both 0. • 1-connectedness is equivalent to connectedness for graphs of at least 2 vertices. See more • Connectedness is preserved by graph homomorphisms. • If G is connected then its line graph L(G) is also connected. • A graph G is 2-edge-connected if and only if it has an orientation … See more Webdi c and sum-connectivity energy of directed graphs.

WebThere are 3 types of connectivity when talking about a directed graph G. 1) weakly connected - replacing all of G 's directed edges with undirected edges produces a … WebNov 2, 2013 · How about this: 1 Begin at any arbitrary node of the graph, G 2.Proceed from that node using either depth-first or breadth-first search, counting all nodes reached. 3. Once the graph has been entirely traversed, if the number of nodes counted is equal to the number of nodes of G, the graph is connected; otherwise it is disconnected. –
