Key Concepts

Undirected Graph

An undirected graph is a collection of vertices connected by edges, where the edges do not have a direction. This means that if there is an edge between vertex A and vertex B, it can be traversed in both directions. Undirected graphs are commonly used to model mutual relationships in networks where the connection is bidirectional.

Adjacency Matrix Representation

An adjacency matrix is a square matrix used to represent a graph, where each element indicates whether pairs of vertices are adjacent or not in the graph. In the matrix, the rows and columns correspond to vertices and a nonzero entry indicates the presence of an edge between the corresponding vertices. For undirected graphs, the matrix is symmetric since the edge (i, j) is identical to the edge (j, i).

Weighted Graph

A weighted graph is one in which each edge is assigned a specific value or weight. These weights can represent the cost, distance, or any quantitative measure associated with the connection between two vertices. When an adjacency matrix contains numbers other than 0 or 1, those values typically indicate the weights of the edges connecting the vertices.

Graph Drawing

Graph drawing involves creating a visual representation of a graph that reflects the relationships between nodes. In the context of an undirected, weighted graph, this usually means drawing vertices as points and edges as lines connecting them, with labels on the edges to denote their weights. This visualization helps in understanding the structure and properties of the graph.
