As we draw closer to Christmas and winter sets in, the days become shorter and darker, with the winter solstice marking the shortest day of the year. But when exactly is the shortest day of the year, ...
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 ...
Kamala Harris’s 107 Days offers a devastating indictment of Joe Biden. It also documents the limits of her own politics. Presidents cast long shadows. Vice presidents are usually doomed to live in ...
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 ...
