Complexity theory is a fundamental branch of theoretical computer science that categorises computational problems according to their inherent difficulty and the resources required to solve them. At ...

Seeking to reduce the computing power needed for the widely used dynamic mode decomposition algorithm, a team of researchers in China led by Guo-Ping Guo developed a quantum-classical hybrid algorithm ...

As organizations increasingly rely on algorithms to rank candidates for jobs, university spots, and financial services, a new ...

Across the United States and Europe, software is making probation decisions and predicting whether teens will commit crime. Opponents want more human oversight. Darnell Gates, on probation in ...

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 Lamport algorithm for generating and applying one-time passwords (OTPs) is a simple solution that provides great value in the right context. Not only can the Lamport OTP scheme provide effective ...

Climate models can be a million lines of code long and can take months to run on supercomputers. A new algorithm has dramatically shortened that time. When you purchase through links on our site, we ...

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 ...

YouTube has started adjusting the ranking of videos in YouTube search to reward engaging videos that keep viewers watching. In other words, “watch time” has replaced “view count” in the YouTube ...
