Our first method for organized graph traversal is called depth-first search (DFS). Whenever a vertex \(v\) is visited during the search, DFS will recursively visit all of \(v\) ‘s unvisited neighbors. Equivalently, DFS will add all edges leading out of \(v\) to a stack. The next vertex to be visited is determined by …
