Everyone knows that the path of least resistance is the path that will always be taken, be it by water, electricity or the ...

Shortest path algorithms sit at the heart of modern graph theory and many of the systems that move people, data, and goods around the world. After nearly seventy years of relying on the same classic ...

Rahmanullah Lakanwal was among the Afghans who came to the United States after the Taliban takeover of Afghanistan. Earlier, he served in a paramilitary unit that worked with U.S. forces. By Campbell ...

When Edsger W. Dijkstra published his algorithm in 1959, computer networks were barely a thing. The algorithm in question found the shortest path between any two nodes on a graph, with a variant ...

The original version of this story appeared in Quanta Magazine. 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 ...

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.

It's a phenomenon that has left scientists baffled, but the Earth's rotation is spinning unusually fast and Wednesday may be the shortest day ever on record. The shortest day of the year could fall ...

Scientists are raising alarm bells as Earth’s rotation speeds up unexpectedly, leading to what may soon be the shortest day in recorded history. According to Graham Jones, an astrophysicist at the ...

Finding the shortest path in a network is a classical problem, and a variety of search strategies have been proposed to solve it. In this paper, we review traditional approaches for finding shortest ...
