Computer Scientists Inch Closer to Major Algorithmic Goal
A new paper finds a faster method for determining when two mathematical groups are the same.
The Most Important Machine That Was Never Built
When he invented Turing machines in 1936, Alan Turing also invented modern computing.
How Randomness Improves Algorithms
Unpredictability can help computer scientists solve otherwise intractable problems.
Finally, a Fast Algorithm for Shortest Paths on Negative Graphs
Researchers can now find the shortest route through a network nearly as fast as theoretically possible, even when some steps can cancel out others.
New Algorithm Closes Quantum Supremacy Window
Random circuit sampling, a popular technique for showing the power of quantum computers, doesn’t scale up if errors go unchecked.
The Year in Computer Science
Computer scientists this year learned how to transmit perfect secrets, why transformers seem so good at everything, and how to improve on decades-old algorithms (with a little help from AI).
After a Quantum Clobbering, One Approach Survives Unscathed
A quantum approach to data analysis that relies on the study of shapes will likely remain an example of a quantum advantage — albeit for increasingly unlikely scenarios.
Crucial Computer Program for Particle Physics at Risk of Obsolescence
Maintenance of the software that’s used for the hardest physics calculations rests almost entirely with a retiree. The situation reveals the problematic incentive structure of academia.
AI Reveals New Possibilities in Matrix Multiplication
Inspired by the results of a game-playing neural network, mathematicians have been making unexpected advances on an age-old math problem.
