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 ...

You know physical activity is good for you. But if you've only got a few minutes, is it worth putting on your sneakers? Recent research suggests the answer is a resounding yes. Even short bouts of ...

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 ...

Days are shortening more and more as we delve into fall and creep closer to winter. The end of daylight saving time is just weeks away, meaning Illinois residents will soon have to turn their clocks ...

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 ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

Kids are returning to school and the feel of fall is in the air with cooling temperatures and earlier sunsets. The clocks too, will fall soon. Here's when daylight saving time ends in 2025. Daylight ...

California is set to experience one of its shortest days on record — and, no, it’s not because summer is winding down in the Northern Hemisphere. The Earth’s full rotation on its axis is gaining speed ...
