Single Source Shortest Paths
Chapter 25
Given a graph and a source vertex "s", compute
the shortest route to each of all other vertices.
The graph is weighted, directed or undirected.
Examples:
 | compute least cost travel itinerary |
 | compute fastest itinerary |
 | compute shortest path |
Variants of the problem:
 | single destination (as opposed to single source) |
 | Single pair - compute shortest path to a given vertex |
 | All pairs |
