Relax edges from each vertex in increasing order of distance from source s. Given a directed graph G = {N, E} where N is the set of nodes of G and E is the set of directed edges, each edge has a non-negative length, we can talk about weight or cost too, and one of the nodes is taken as the origin-node.

It uses weight of edge . Implementing discrete mathematics: combinatorics and graph theory with Mathematica, Steven Skiena. This algorithm helps in converting a graph into a forest, or we can say that it helps in searching a minimum spanning forest of a graph (undirected edge-weighted). The algorithm starts from the source. 4. There is a working label and a permanent label, as well as an ordering label.
