WebDepth-First Search DFS(v): visits all the nodes reachable from v in depth-ﬁrst order Mark v as visited For each edge v → u: – If u is not visited, call DFS(u) Use non-recursive version if recursion depth is too big (over a few thousands) – Replace recursive calls with a stack Depth-First and Breadth-First Search 18 http://jeffe.cs.illinois.edu/teaching/algorithms/book/06-dfs.pdf sharon officeWeb(say by DFS). The running time is . A more elegant algorithm always starts at simple ob-servations. Suppose we run DFS on , we get a DFS tree. If the root has two or more children, it is an ar-ticulation point.

A path is selected until no unvisited nodes remain reachable, then the traversal goes back to the last node that was visited that has unvisited adjacent nodes. A valid result of depth first search of the graph above is 1, 3, 6, 7, 8, 2, 5, 4.

Step 1: One of the standard rule before starting with DFS algorithm is that DFS puts each vertex of graph into two categories i.e. Visited & Non Visited. Step 2: Keeping in mind that each vertex is visited at least once without making cycles. Step 3: First, need to put any one graph vertices on top of the stack.
