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

The intersection of the PLS and PPAD classes itself forms a class of problems known as PLS int PPAD. It contains many natural problems relevant to complexity researchers. However, until now, ...

To complexity theorists and algorithm designers, this is bad. (Or, technically speaking, hard.) SETH takes this situation from bad to worse. It implies that finding a better general-purpose algorithm ...

A complexity class contains all problems that can be solved within a given resource budget, ... Computer scientists have found an efficient algorithm, for example, for testing whether a number is ...
