WebDepth–first search in Graph. A Depth–first search (DFS) is a way of traversing graphs closely related to the preorder traversal of a tree. Following is the recursive implementation of preorder traversal: To turn this into a graph traversal algorithm, replace “child” with “neighbor”. But to prevent infinite loops, keep track of the ... WebOct 11, 2024 · 2. Depth-first search. The depth-first search uses Last-in, First-out (LIFO) strategy and hence it can be implemented by using stack. DFS uses backtracking. That is, it starts from the initial state and explores each path to its greatest depth before it moves to the next path. DFS will follow.
