WebAdjacency matrices are very good for dense graphs, and adjacency lists are good for sparse graphs. So it depends on what your graph looks like, but it also depends on whether you care more about running time or memory. If you represent your adjacency matrix as a hash table, you can get very good lookup times without using n^2 memory. WebBreadth first search in java. Depth first search in java.

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.
