Graphs come with various properties which are used for characterization of graphs depending on their structures. These properties are defined in specific terms pertaining to the domain of graph theory. In this chapter, we will discuss a few basic properties that are common in all graphs.

WebIn these graphs, Each vertex is connected with all the remaining vertices through exactly one edge. Therefore, they are complete graphs. 9. Cycle Graph-. A simple graph of ‘n’ vertices (n>=3) and n edges forming a cycle of length ‘n’ is called as a cycle graph. In a cycle graph, all the vertices are of degree 2.

Webof G = (V,E) is a graph G 0= (V0,E0) where V is a nonempty subset of V and E0 is a subset of E. Since a subgraph is itself a graph, the endpoints of every edge in E0 must be vertices in V0. In the special case where we only remove edges incident to removed nodes, we say that G 0is the subgraph induced on V0 if E = {(x—y x,y ∈ V0 and x—y ... WebNetwork theory deals with modelling problems using directed graphs, extending CS239. Network flow theory deals with flow problems over these directed graphs. A typical problem: given so-and-so network of roads (directed graph), each with different widths (cost of taking a road), how much traffic can we route from point A to B?
