Single Source Shortest Paths
In this section, we consider the singlesource shortestpaths problem: for a given vertex called the source in a weighted connected graph, find shortest paths to all its other vertices. It is important to stress that we are not interested here in a single shortest path that starts at the source and visits all the other vertices. This would have been a much more difficult problem.
The singlesource shortestpaths problem asks for a family of paths, each leading from the source to a different vertex in the graph, though some paths may, of course, have edges in common.
A variety of practical applications of the shortestpaths problem have made the problem a very popular object of study. The obvious but probably most widely used applications are transportation planning and packet routing in communication networks, including the Internet. Multitudes of less obvious applications include finding shortest paths in social networks, speech recognition, document formatting, robotics, compilers, and airline crew scheduling. In the world of entertainment, one can mention path finding in video games and finding best solutions to puzzles using their statespace graphs
