WebThe adjacency matrix representation of the above-directed graph is: Note that for an undirected graph, the adjacency matrix is always symmetric. For a weighted graph, instead of 0 and 1, the value of weight w is used to indicate that there is an edge from i to j. Implementation. The Implementation of Graphs in Python using Adjacency Matrix is ... Web2. Using an adjacency matrix. The following code implements a graph using an adjacency matrix: add_vertex (v) adds new vertex v to the graph, and add_edge (v1, v2, e) adds an edge with weight e between vertices v1 and v2. # Add a vertex to the set of vertices and the graph. def add_vertex (v): global graph. global vertices_no.
