One computer scientist’s “stunning” proof is the first progress in 50 years on one of the most famous questions in computer ...

Most problems can be solved by many different algorithms, each with its own demands on time and space. Complexity theorists sort problems into categories, called complexity classes, based on the ...

Using an advanced Monte Carlo method, Caltech researchers found a way to tame the infinite complexity of Feynman diagrams and ...

But those algorithms aren’t all the same. The time each one takes to find the right answer will vary depending on where and when it’s used, and cases that are hard for one algorithm may be ...
