The real-world version of the famous “traveling salesman problem” finally gets a good-enough solution.

Just five days after posting a retraction, László Babai announced that he had fixed the error in his landmark graph isomorphism algorithm.

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.

Recent tests show that quantum computers made by D-Wave systems should solve some problems faster than ordinary computers. Researchers have begun to map out exactly which queries might benefit from these quantum machines.

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