WebDec 1, 2014 · A tree edge is an edge in a DFS-tree. A back edge connects a vertex to an ancestor in a DFS-tree. Note that a self-loop is a back edge. A cross edge is any other edge in graph G. It connects vertices in two different DFS-tree or two vertices in the same DFS-tree neither of which is the ancestor of the other. Tree edges { ( a, b), ( b, e), ( e ... WebThe edges of G can be partitioned into 4 classes: tree edges - ( u, v) is a tree edge iff ( u, v) ∈ G π. back edges - edges connecting a vertex to itself or to one of its ancestors in G π. forward edges - edges connecting a vertex to one of its descendants in G π. cross edges - the rest of the edges. When G is an undirected graph, we ...

For example, tree edges form trees containing each vertex DFS visited in G. Also, G has a cycle if and only if DFS finds at least one back edge. headquarters support system
