"WebFeb 11, 2024 · Example: 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. " - Dfs in matrix
