WebFeb 23, 2024 · Characteristics of a Graph. A graph is defined in formal terms as a pair (V, E), where V is a finite collection of vertices and E is a finite set of edges. So there are two parts of graph: A node or a vertex. A link between two nodes u, v that may be uniquely identified as an edge E or ordered pair is called a node (u,v). WebThe objects correspond to mathematical abstractions called vertices (also called nodes or points) and each of the related pairs of vertices is called an edge (also called link or line ). [1] Typically, a graph is depicted in diagrammatic form as a set of dots or circles for the vertices, joined by lines or curves for the edges. bishop aldhelm\u0027s preschool https://b-vibe.com

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 problems. The connectivity of a graph is an important measure of its resilience as a netw…
