WebDepth First Search-. Depth First Search or DFS is a graph traversal algorithm. It is used for traversing or searching a graph in a systematic fashion. DFS uses a strategy that searches “deeper” in the graph whenever possible. Stack data structure is used in the implementation of depth first search. WebFeb 11, 2024 · To detect a cycle in a directed graph (i.e to find a back edge), you can use depth-first search (with some introduction of local state to tell you if a back edge occurs): We will maintain 3 buckets of vertices: white, grey, & black buckets. (We can also colour vertices instead). The white bucket will contain all of the unvisited vertices.
