WebDec 1, 2024 · Depth-First Search Algorithm. The Depth-First Search (also DFS) algorithm is an algorithm used to find a node in a tree. This means that given a tree data structure, the algorithm will return the first node in this tree that matches the specified condition (i.e. being equal to a value). Nodes are sometimes referred to as vertices (plural of ... WebThe DFS is an algorithm used to traverse the target node in a graph or tree data structure.
