![]() ![]() It is hosted at the LCZero site and there one can not only find the engine but the latest version of the neural networks - the brain if you will. ![]() Leela Chess Zero is based on the seminal Alpha Zero paper, using the same self-learning techniques and the same Monte Carlo Tree Search technique. Then there is the matter of trying to translate Deep Mind’s explanations in their paper into concrete computer code.īut some programmers took up the challenge, and after developing a Go program, Leela Zero, the strongest one publicly available now, based on community effort and contributions, it has been transferred to chess. For one thing, a single person could hardly do it at home with a single machine, or even a room full. This was not nearly as easy as might seem. The paper " Mastering Chess and Shogi by Self-Play with a General Reinforcement Learning Algorithm" at Cornell University What was more, anyone was invited to make their own. Much was made about the conditions of the match against a 64-thread version of Stockfish used to test its strength, but this was to completely overlook the important aspect of it all: a new world-class engine, using a completely new method and technique, had been developed in 24 hours. The new Alpha Zero chess program lead to an astounding media frenzy, and just as much controversy in the chess world. Deep Blue had a system performance of 12 GFLOPS, while the horsepower DeepMind used easily exceeded 40 million GLOPS.ĭeepMind's professor David Silver explains the new 'Zero' approach in AlphaGo Zero, which preceded Alpha Zero (chess) had thought that just piling in special hardware would somehow solve chess for them in 24 hours, they would have done it. Naturally, there were plenty of special conditions in play, such as having access to thousands of incredibly powerful processors to help develop its ability in such a short time, but they did it. Then along came Deep Mind, who poured in their resources and built a world-beating engine that learned the game itself within 24 hours. After all, Go is less about calculating exact lines, and more about extensive pattern recognition, while chess is highly tactical and seeing just a single extra move ahead can make or break a program. Nevertheless, it was believed that while a game such as Go, might fit this form of software engineering, it would never really work for a chess program. As a sidenote, Feng Hsu and the Deep Blue team did eventually publish papers describing the entire thing inside and out. In a sense, this was the equivalent of IBM creating the world-beating Deep Blue, and then publishing blueprints the very same day so that anyone could build their own. It was the result of a powerful artificial intelligence technique known as deep reinforcement learning, which built a neural network combined with the Monte Carlo Tree Search that allowed the program, equipped with just the barebones rules of the game, to play itself millions upon millions of times, learning as it went until it reached, as was the case, superhuman playing strength.Īll the more remarkable was that the Deep Mind group published peer-reviewed papers that detailed exactly how it was achieved. When Alpha Go, and then Alpha Go Zero, was released, it cracked one of the most challenging strategic games in the world, and one that experts all over had thought would resist for at least another decade.
