triple G:=(V, E, f) V is a set of nodes, points, or vertices. E is a set, whose elements are known as edges or lines. f is a function maps each element of E to an unordered pair of vertices in V. Definitions Vertex Basic Element Drawn as a node or a dot. Vertex set of G is usually denoted by V(G), or V Edge A set of two elements Drawn as a line connecting two vertices, called end vertices, or endpoints. The edge set of G is usually denoted by E(G), or E. Example V:={1…
