WebGraph Algorithms. Graph Search Algorithms. Tree edges are edges in the search tree (or forest) constructed (implicitly or explicitly) by running a graph search algorithm over a graph. An edge (u,v) is a tree edge if v was first discovered while exploring (corresponding to the visitor explore() method) edge (u,v). Back edges connect vertices to their … WebA tree T is said to be a spanning tree of a connected graph G if T is a subgraph of G and T contains all vertices of G.
