An artificial intelligence system created by researchers at the University of California has solved the Rubik’s Cube in a fraction of a second.
DeepCubeA, as the algorithm was called, completed the 3D logic puzzle which has been taxing humans since it was invented in 1974.
“It learned on its own,” said report author Prof Pierre Baldi.
The researchers noted that its strategy was very different from the way humans tackle the puzzle.
“My best guess is that the AI’s form of reasoning is completely different from a human’s,” said Prof Baldi, who is professor of computer science at University of California, Irvine.
The study, published in Nature Machine Intelligence, saw the algorithm given 10 billion different combinations of the puzzle, with the target to decode all of them within 30 moves.
It was then tested on 1,000 of these and managed to solve all of them, finding the shortest path to the solution about 60% of the time…
