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 ancestors in a … WebA 0/1 BFS finds the shortest path in a graph where the weights on the edges can only be 0 or 1, and runs in \mathcal {O} (V + E) O(V +E) using a deque.
