A Supercomputer Solves Rubik's Cube
Supercomputers have taken on the world’s most pressing and complex scientific quandaries — global warming, genetics, even the formation of the universe. Now a high-speed machine at Northeastern University has taken on a more colorful question: How quickly can one solve a Rubik’s Cube?
After reducing the 43 quintillion possible configurations to a more manageable 80 million, the supercomputer proved that any of the cubes — no matter how hopeless-looking — can be properly aligned within just 26 moves. So take heart, you who have spent hours twisting your own stubborn Rubik’s. —Brock Read
