distance -- Computes the distance between two vertexSet in a graph

Synopsis

Usage:

d = distance(G,v,u)
Inputs:
- G, an instance of the type Graph,
- v, a thing,
- u, a thing,
Outputs:
- d, an integer, The distance between vertexSet v and u

Description

The distance between two vertexSet is calculated as the number of edges in the shortest path between the two vertexSet. If the two vertexSet are not connected, the distance between them is infinity by convention.

i1 : G = graph({{1,2},{2,3},{3,4}},EntryMode=>"edges");

i2 : d = distance (G,1,4)

o2 = 3

i3 : G = graph({1,2,3,4},{{2,3},{3,4}});

i4 : d = distance(G, 1, 4)

o4 = infinity

o4 : InfiniteNumber
