Reed–Solomon codes have long been celebrated for their robust error-correction capabilities in digital communications and data storage. Decoding algorithms for these codes continue to evolve, aiming ...

A major advance reveals deep connections between the classes of problems that computers can — and can’t — possibly do. At first glance, the big news coming out of this summer’s conference on the ...

Often, when there’s talk about algorithms and journalism, the focus is on how to use algorithms to help publishers share content better and make more money. There’s the unending debate, for example, ...
