WebJun 8, 2024 · Depth-First Search is a recursive algorithm to “search” through all of the nodes in a graph. How it works is like so: Starting off with a node, we mark it as visited, then for each of its neighbors that is not visited, we call depth first search on them.

Depth First Traversal (or Search) for a graph is similar to Depth First Traversal of a tree. The only catch here is, unlike trees, graphs may contain cycles, so we may come to the same node again. To avoid processing a node more than once, we use a boolean visited array.

WebWhat is the cost of recursive DFS for a graph with v vertices and e edges? The function dfs creates an array of marks with all positions initialized to zero (i.e., to false) on line30. This takes O(v) time. The call to free is constant time. Therefore, the asymptotic complexity of dfs is equal to the cost of the call to dfs_helper on line31.
