WebDec 19, 2024 · Back edge : In the depth-first tree, edge (u, v) is called back edge if edge (u, v) connects a vertex u to an ancestor v. Self-loop is considered as back edge. Forward edge : Forward edge (u, v) is the non-tree edge that connects vertex v to its descendent in the depth-first tree. Cross edge : Remaining all edges is classified as cross edges. WebSep 3, 2024 · Forward edges cannot exist because their possibility of existence implies that they should have been used as a tree edge for traversal earlier. For example, though A-I visually looks like a...

Deciding if a graph is "Single Connected"

WebAug 9, 2024 at 18:23. @ElleryL, I'm pretty sure this is true for an undirected graph. In an undirected graph, BFS should only produce tree edges and cross edges. Cross edges will always be produced if there are cycles in the undirected graph (i.e. m ≥ n ). This is similar to how dfs on undirected graph produces only tree edges and back edges. http://cs.williams.edu/~shikha/teaching/spring20/cs256/lectures/Lecture05.pdf synonyms for extremely wellWebDec 5, 2024 · You are correct that in directed graphs there are four kinds of edges: tree, back, forward and cross edges.

WebForward edges are those nontree edges ( u, v) connecting a vertex u to a descendant v in a depth-first tree. Cross edges are all other edges. They can go between vertices in the same depth-first tree, as long as one vertex is not an ancestor of the other, or they can go between vertices in different depth-first trees.
