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 - ...

An optimality index for choosing the shortest route in an acyclic, stochastic network has recently been proposed. The present note identifies certain anomalies in using that index and proposes another ...

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 ...
