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 ...

For more than half a century, researchers around the world have been struggling with an algorithmic problem known as "the single source shortest path problem". The problem is essentially about how to ...

In recent years, the Massively Parallel Computation (MPC) model has gained significant attention. However, most of distributed and parallel graph algorithms in the MPC model are designed for static ...

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 - ...

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 the easiest pieces first. But this kind of sorting has a cost.

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 ...
