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, &amp; black buckets. (We can also colour vertices instead). The white bucket will contain all of the unvisited vertices. WebFeb 26, 2024 · An adjacency matrix is a 2d array representing a graph.

WebJun 8, 2024 · This is the most simple implementation of Depth First Search. As described in the applications it might be useful to also compute the entry and exit times and vertex color. We will color all vertices with the color 0, if we haven't visited them, with the color 1 if we visited them, and with the color 2, if we already exited the vertex. WebMay 28, 2024 · An undirected graph has a cycle if and only if a depth-first search (DFS) finds an edge that points to an already-visited vertex (a back edge). Find a cycle in directed graphs.
