The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...

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 ...

Is Shortest Path Bridging (SPB) winning the data center fabric standards battle? One could have walked away from Interop 2012 with that impression, given the level of interest in it during a ...

Mathematics of Operations Research, Vol. 38, No. 2 (May 2013), pp. 209-227 (19 pages) We consider a totally asynchronous stochastic approximation algorithm, Q-learning, for solving finite space ...

This paper considers the shortest path problem with waiting costs (SPWC) as an extension to the shortest path problem with time windows. The problem consists of finding the minimum cost path in a ...
