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 …

WebMar 26, 2024 · DFS Algorithm. Step 1: Insert the root node or starting node of a tree or a graph in the stack. Step 2: Pop the top item from the stack and add it to the visited list. Step 3: Find all the adjacent nodes of the node marked visited and add the ones that are not yet visited, to the stack. Step 4: Repeat steps 2 and 3 until the stack is empty.
