We’re going to start with depth-first search, also referred to as DFS, because it’s actually quite similar to the algorithm for binary tree traversal that we discussed back in Binary Search Tree Traversal. In fact, it’s also the same essential algorithm that we saw in Filesystem Traversal.
As mentioned earlier, graph search can be used either to find a particular vertex or to simply traverse the graph. We’re going to begin by using depth-first search to traverse the graph since that algorithm is slightly simpler.
