Using computers lent to them by Google - the company won't disclose how many or how powerful they are - the team crunched through billions of Cube positions, solving each one over a period of 'just a few weeks.' 'It is appropriate that fifteen years after that, we prove that twenty moves suffice for all position.' 'It took fifteen years after the introduction of the Cube to find the first position that provably requires 20 moves to solve,' the team said. The research, published online, ends a 30-year search for the most efficient way to correctly align the 26 colored cubes that make up Erno Rubrik's 1974 invention. At long last, God's Number has been shown to be 20.' The number of moves this algorithm would take in the worst case is called God's Number. 'One may suppose God would use a much more efficient algorithm, one that always uses the shortest sequence of moves this is known as God's Algorithm. 'There are many different algorithms, varying in complexity and number of moves required, but those that can be memorized by a mortal typically require more than forty moves.' 'Every solver of the Cube uses an algorithm, which is a sequence of steps for solving the Cube,' said the team of mathematicians, who include Morley Davidson of Ohio's Kent State University, Google engineer John Dethridge, German math teacher Herbert Kociemba and Tomas Rokicki, a California programmer. The study is just the latest attempt by Rubik's enthusiasts to figure out the secrets of the cube, which has proven to be altogether far more complicated that its jaunty colors might suggest.ДЄt the crux of the quest has been a bid to determine the lowest number of moves required to get the cube from any given muddled configuration to the color-aligned solution.
