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 ...

Rozhoň suggested they try to devise a universally optimal algorithm for the single-source shortest-paths problem ... the internet could shake up the AI industry with a giant 100 billion ...

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 ...

“Vector-based navigation does not produce the shortest path, but it’s close enough ... and Machines and the Computer Science and Artificial Intelligence Laboratory (CSAIL), is also an author ...

For example, if recent rain has turned unsealed roads into mud, some “shortest-path” algorithms may be unreliable unless they can anticipate the likely impact of weather on travel times when ...
