Robot vs. Rubik's Cube.

In October, a researcher at the OpenAI artificial intelligence lab in San Francisco scrambled the tiles of a Rubik's Cube and placed it in the palm of a robotic hand. Four minutes later, the machine had solved the puzzle. The human world record is only 3.47 seconds, but mastering the cube was a major breakthrough for robotics--the first time a device that works like a human hand had done it. The team had spent months training the robot, even building a computer system that could learn to solve the cube largely on its own. Now they say the experiment's success indicates that iffiT ??!!! machines could be trained to perform far...
