One of the most classic algorithmic problems deals with calculating the shortest path between two points. A more complicated variant of the problem is when the route traverses a changing network - ...

In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...

We introduce an informative labelling method for vertices in a family of Farey graphs and deduce a routing algorithm on all the shortest paths between any two vertices in Farey graphs. The label of a ...
