WebFeb 22, 2024 · An adjacency matrix is a square matrix used to represent a finite graph. The matrix represents whether 2 nodes are adjacent or not- i.e. if there is an edge between 2 nodes having some weight. WebJul 26, 2024 · Thus we usually don't use matrix representation for sparse graphs. We prefer adjacency list. But if the graph is dense then the number of edges is close to (the complete) n ( n − 1) / 2, or to n 2 if the graph is directed with self-loops. Then there is no advantage of using adjacency list over matrix. In terms of space complexity. WebMay 29, 2024 · Adjacency Matrix.
