WebBreadth-first-search is the algorithm that will find shortest paths in an unweighted graph. There 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.
