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 ...

the shortest path in a dynamic network. For 40 years, researchers have been working to find an algorithm that can optimally solve this mathematical conundrum. Now, Christian Wulff-Nilsen of the ...

the idea is that the algorithm can be used to calculate the shortest path between two locations. In the project designed by Eveleigh, the idea was to create an abstract map of the Cotswolds ...

Following a similar design process, we will design efficient algorithms for a sequence of problems: shortest paths, minimal cycle ratios, maximal network flows, min-cost flows, and convex cost flows.
