Representation of Graphs

Two approaches to represent a graph will be covered in this lesson.

Ways to Represent a Graph

The two most common ways to represent a graph are:

  1. Adjacency Matrix
  2. Adjacency List

Adjacency Matrix

The adjacency matrix is a two dimensional matrix where each cell can contain a 0 or 1. The row and column headings represent the vertices.

If a cell contains 1, there exists an edge between the corresponding vertices, e.g., Matrix[0][1]=1Matrix[0][1]=1 shows that an edge exists between vertex 0 and 1.
