Otherwise, it is called a disconnected graph. In a directed graph, an ordered pair of vertices (x, y) is called strongly connected if a directed path leads from x to y. ... Graph Theory (1st ed.).

A graph G = ( V, E) that is not simple can be represented by using multisets: a loop is a multiset { v, v } = { 2 ⋅ v } and multiple edges are represented by making E a multiset. The condensation of a multigraph may be formed by interpreting the multiset E as a set. A general graph that is not connected, has ...
WebMar 24, 2024 · Connected Digraph. There are two distinct notions of connectivity in a directed graph. A directed graph is weakly connected if there is an undirected path between any pair of vertices, and strongly connected if there is a directed path between every pair of vertices (Skiena 1990, p. 173). The following tables summarized the … WebMay 15, 2024 · Connected Component Definition. A connected component or simply component of an undirected graph is a subgraph in which …
WebIn graph theory, we usually use the graph to show a set of objects, and these objects are connected with each other in some sense. The objects can be described as mathematical concepts, which can be expressed with the help of nodes or vertices, and the relation between pairs of nodes can be expressed with the help of edges.
