The legendary graph isomorphism problem may be harder than a 2015 result seemed to suggest.

The computer scientist Cynthia Dwork takes abstract concepts like privacy and fairness and adapts them into machine code for the algorithmic age.

When divvying something up, there's more than one way to define what's fair.

Computer scientists have come up with a bounded algorithm that can fairly divide a cake among any number of people.

Computer scientists can prove certain programs to be error-free with the same certainty that mathematicians prove theorems.

The biological world is computational at its core, argues computer scientist Leslie Valiant.

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

The physical nature of computers might reveal deep truths about their uniquely powerful abstract abilities.

A theorem for coloring a large class of “perfect” mathematical networks could ease the way for a long-sought general coloring proof.
