GraphDistance

GraphDistance[g,s,t]

gives the distance from source vertex s to target vertex t in the graph g.

GraphDistance[g,s]

gives the distance from s to all vertices of the graph g.

GraphDistance[{vw,…},…]

uses rules vw to specify the graph g.

Details and Options

  • GraphDistance is also known as geodesic distance.
  • GraphDistance[g,s,t] will give the length of the shortest path between s and t.
  • The distance is Infinity when there is no path between s and t.
  • For a weighted graph, the distance is the minimum of the sum of weights along any path between s and t.
  • The following options can be given:
  • Method Automaticmethod to use
  • Possible Method settings include "Dijkstra", "BellmanFord", and "UnitWeight".

Method  (4)

The method is automatically chosen, depending on input:

"UnitWeight" method will use the weight 1 for every edge:

"Dijkstra" can be used for graphs with positive edge weights only:

"BellmanFord" can be used for directed graphs, including negative edge weights:
