When we tested our algorithms with the widely used sample data sets, we were surprised at how well they performed relative to open-source algorithms assembled by IBM.

Computer scientists are abuzz over a fast new algorithm for solving one of the central problems in the field.

Can we ever really trust algorithms to make decisions for us? Previous research has proved these programs can reinforce society’s harmful biases, but the problems go beyond that. A new study ...

This sort of exponential growth is the defining feature of a hard computational problem. But not all hard problems are equally hard — some have algorithms that are faster than exhaustive search, ...
