Algorithms

Seventy years after the invention of a data structure called a hash table, theoreticians have found the most efficient possible configuration for it.

Two mathematicians have shown that origami can, in principle, be used to perform any possible computation.

Integer linear programming can help find the answer to a variety of real-world problems. Now researchers have found a much faster way to do it.

Artificial intelligence learned how to generate text and art better than ever before, while computer scientists developed algorithms that solved long-standing problems.

Two researchers have improved a well-known technique for lattice basis reduction, opening up new avenues for practical experiments in cryptography and mathematics.

Researchers prove that navigating certain systems of vectors is among the most complex computational problems.

Three computer scientists have disproved a long-standing conjecture about a fundamental problem involving imperfect information.

What makes a quantum computer more powerful than a classical computer? It’s a surprisingly subtle question that physicists are still grappling with, decades into the quantum age.

Shor’s algorithm will enable future quantum computers to factor large numbers quickly, undermining many online security protocols. Now a researcher has shown how to do it even faster.
