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 ...

For decades, engineers have utilized Petri nets to develop automated systems with specific functional requirements or ...

Instead, it gives you an ordered list of travel times from your current location to every other point that you might want to visit — a solution to what researchers call the single-source ...

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 ...
