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 ... WebDefinition of DFS Algorithm in Python. DFS algorithm in python or in general is used for searching and traversing data structure. DFS algorithm uses the idea of backtracking, in which one node is selected as the root node and it starts traversing them one by one. DFS algorithm is used to perform the searching and traversing for the data ...
