Graph theory deals with routing and network problems and if it is possible to find a “best” route, whether that means the least expensive, least amount of time or the least distance. Some examples of routing problems are routes covered by postal workers, UPS

Webthis is a Cayley graph, we label each of these edges with the generator that created that edge: for this graph, because there’s only one generator this is pretty simple (we just label every edge with a 1.)
