WebThere is a simple tweak to get from DFS to an algorithm that will find the shortest paths on an unweighted graph. Essentially, you replace the stack used by DFS with a queue. However, the resulting algorithm is no longer called DFS. Instead, you will have implemented breadth-first-search.

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.
