ShortestPath

ShortestPath[g, start, end]
finds a shortest path between vertices start and end in graph

To use ShortestPath, you first need to load the Combinatorica Package using Needs["Combinatorica`"].

An option Algorithm that takes on the values Automatic, Dijkstra, or BellmanFord is provided. This allows a choice between using Dijkstra's algorithm and the Bellman-Ford algorithm.

The default is Algorithm->Automatic. In this case, depending on whether edges have negative weights and depending on the density of the graph, the algorithm chooses between BellmanFord and Dijkstra.
