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 ...

it could help you beat rush hour traffic in every city in the world. Finally, a Fast Algorithm for Shortest Paths on Negative Graphs “This sounds too good to be true,” said Bernhard Haeupler, a ...

However, there are no existing dynamic all-pairs shortest paths (APSP) algorithms working in the MPC model. To solve the problems, a research team led by Qiang-Sheng HUA published their new ...
