Step 1

The adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph. In the adjacency matrix, the entry in the i-th row and j-th column is equal to the number of Show more…

Key Concepts

Adjacency Matrix

An adjacency matrix is a structured way to represent a graph using a square matrix where each row and column corresponds to a vertex. In this representation, the entries indicate whether pairs of vertices are adjacent and, in weighted graphs, can also represent the strength or weight of the edge connecting them.

Graph Representation

Graph representation encompasses the different methods of describing graphs, such as through lists, matrices, or diagrams. Choosing an appropriate representation like an adjacency matrix aids in both understanding the structure of a graph and performing algorithmic computations on it.

Undirected Graph

An undirected graph is a collection of vertices connected by edges that have no inherent direction; that is, the edge between any two vertices can be traversed in both ways. This type of graph is fundamental in graph theory and is used to model symmetric relationships between entities.
