WebJan 7, 2015 · The matrix representation gives the advantage when the graph is dense, meaning when most of the nodes/vertices are connected to each other. This is because in such cases, by using the entry of matrix, it saves us from having to allocate an extra pointer (which need a word size memory) for each connection.
