What is an adjacency matrix - Javatpoint
WebAn adjacency matrix is a way of representing the relationships of these vertices in a 2D array. For unweighted graphs, if there is a connection between vertex i and j, then the value of the cell [i,j] will equal 1, if there is not a connection, it will equal 0. When graphs become weighted, the value of 1 is replaced with the "cost" of the edge ... WebOct 1, 2024 · Adjacency matrix (A(G)) is a matrix of size m×m which is defined as That is to say if two vertices are adjacent then we write 1, otherwise 0.
