WebAnother one is called the adjacency matrix representation, Here we maintain a 2-dimensional v x v array, It's a boolean array, 0-1 or true or false. And for every edge v-w in the graph you put true for row v in column w and for row w in column v. So it's actually two representations of each edge in an adjacency matrix graph representation. WebIn graph theory and computer science, an 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..
