This will be the underlying structure for our Graph class. You also have to know if these connections are arcs (directed, connect one way) or edges (undirected, connect both ways).

Applications, Advantages and Disadvantages of Graph

WebOct 17, 2013 · So you are using O(V) memory for just storing the empty lists. Next, notice that if the graph is directed, every edge appears exactly once in the array of those lists. If the graph is undirected, every edge appears exactly twice in the array of those lists. In both cases, the number of entries in the whole array is bounded by at most 2 * E = O(E). WebAn adjacency matrix is a way of representing a graph as a matrix of booleans (0's and 1's).

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.
