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 … Webadjacent. A graph with more than one edge between a pair of vertices is called a multigraph while a graph with loop edges is called a pseudograph. De nition 11. A directed graph is a graph in which the edges may only be traversed in one direction. Edges in a simple directed graph may be speci ed by an ordered pair (v i;v j) simply next https://shconditioning.com
