An Artificial Intelligence (AI) built by Google’s DeepMind just beat a champion of the complex strategy game Go, a feat that may have enormous implications for AI research.
Go is often described as the “Chinese version of Chess,” but that description barely does the deceivingly simplistic game justice. The object of the game is to have majority control of the board. You do so by placing your white (or black) pieces (stones) on the board and using them to surround your opponent’s pieces so that they are forced to remove them. If it sounds less complicated than chess, it’s not. To put things in perspective, for each move in chess you have about 40 options. Each move on the 19-by-19 Go grid affords you 200 choices.
“There are more configurations on the board than there are atoms in the universe”
DeepMind applied machine learning with not one, but two neural networks called “Policy” and “Value.” Both look at Go’s myriad game play possibilities, but in two quite specific ways. Policy narrows the field of possible moves to a handful of promising ones, while Value looks for positive outcomes without driving all the way to every possible game conclusion. Policy network looks at some 30 million games by human Go experts to accurately predict moves up to 57% of the time. The previous record was 44%. AlphaGo essentially plays millions of games between its two neural networks and learns how to be a better Go player through trial and error and reinforcement learning.

In April 2015, teenager Collin Burns finished solving a standard-sized 3x3x3 Rubik’s Cube in only 5.25 seconds, claiming a new world record for the feat from the 5.55-second time posted by previous record holder Mats Valk. In November 2015, however, Lucas Etter once again broke the record by finishing a Rubik’s Cube in just 4.904 seconds.
Apparently though, the ability of humans to solve the 3x3x3 puzzle does not hold a candle to the ability of robots to do the same, as a pair of software engineers have created a robot that can solve a Rubik’s Cube in just over a second. The machine is built using 3D-printed frames, stepper motors, and four USB web cameras that are connected to a PC. The cameras scan the Rubik’s Cube to begin analyzing the puzzle through the Kociemba solving algorithm, and the solution is then carried out by the robot in lightning fast movements.

If you didn’t hate Math already… A university computer in Missouri has found the new largest prime number. It is made up of 22,338,618 digits, nearly 5 million more than the previous record. The figure was identified after 31 days of non-stop computing on a machine used by Curtis Cooper, a professor of computer science at the University of Central Missouri, who has now detected four of these record-breaking primes. The new prime number, also known as M74207281, is calculated by multiplying together 74,207,281 twos then subtracting one. It is almost 5 million digits larger than the previous record prime number, in a special class of extremely rare prime numbers known as Mersenne primes. It is only the 49th known Mersenne prime ever discovered, each increasingly difficult to find. Mersenne primes were named for the French monk Marin Mersenne, who studied these numbers more than 350 years ago. GIMPS, founded in 1996, has discovered all 15 of the largest known Mersenne primes. Volunteers can download a free program to search for these primes with a cash award offered to anyone lucky enough to compute a new prime. Full Disclosure – The VooDoo is a GIMPS contributor.

The target: 36″ diameter steel plate, 3600 yards away. Piece of cake! Right? Let’s see – A 36-inch target at 3,600 yards is just under 1 MOA in diameter or 0.5 MOA in radius. this means if your aim is off by anything more the 1/120th of a degree, you would miss. Incredible…
