AI learns to solve a Rubik's Cube in 1.2 seconds
It often cracked the puzzle in just 20 moves.

Researchers at the University of California, Irvine have created an artificial intelligence system that can solve a Rubik's Cube in an average of 1.2 seconds in about 20 moves. That's two seconds faster than the current human world record of 3.47 seconds, while people who can finish the puzzle quickly usually do so in about 50.
However, UC Irvine's DeepCubeA doesn't hold the record for automated Rubik's Cube solving. Last year, researchers built a robot that could complete the puzzle in 0.38 seconds. Massachusetts Institute of Technology's min2phase algorithm, which isn't an AI system, solved it three times faster than DeepCubeA. While other methods were specifically designed to solve the cube, DeepCubeA had to forge its own path.
