How is Alpha Zero "more human"?

I have a possibly naive question about AlphaZero. I have seen it described as playing in a "more human" style than other computers, but whatever it does, it gains about 100 ELO points by doing it. Kasparov, and many others, have claimed that a…

Understanding AlphaZero

Very recently, the news came out that Alphabet's DeepMind research team have extended their machine learning engine to play both Shogi and chess. Apparently, after only a few hours of self-learning, meaning by only playing against itself given the…

Hardware used in AlphaZero vs Stockfish match

I understand that AlphaZero has to use a different kind of hardware than regular Stockfish. I would expect that the hardware has a large effect on engine strength. That's why I wonder whether there have been any attempts made to provide comparable…

Was AlphaZero taught castling?

Since castling involves one player moving two pieces in one move, was AlphaZero just given this move, in the same way it was told that players take turns and a win is better than a loss? In other words, it didn't learn it on its own. (I guess it…

Did AlphaZero also have to learn that each piece has a value?

When AlphaZero learned on its own that a queen has a value of 9, a pawn 1, knight 3, etc., then did it also need to learn on its own that a piece has a value? Or was it that the concept of value was baked into its code and it only had to figure out…

Is it possible Alpha Zero will eventually solve chess?

I googled this question and ended up here. From previous questions, it seems Alpha Zero has not solved chess yet and if it does it will take a very long time. Nonetheless, it may be possible one day. I am wondering whether the programmers, or…

How does AlphaZero learn to evaluate a position it has never seen?

Following up from answers to: Understanding AlphaZero My question would be how the neural net "learns" what to do in a position it hasn't encountered. Saying the actual AZ executes an MCTS using the bias + weights from the trained neural net just…

Did Stockfish have access to an opening book in its games against AlphaZero?

I have seen some commentary that implies that Stockfish did not have access to an opening book in its much-reported match with AlphaZero, but I cannot find a conclusive citation, and my inability to do so has me wondering if maybe Stockfish did have…

Is AlphaZero open source?

There are a lot of fake AlphaZero projects on GitHub. While I was googling if it was open-source, the answer in most places is yes, but I couldn’t find it anywhere. Is there a link to where the code is?

Level the field when letting computers play against each other

I just read this question and it made me wonder: when setting up such a game/comparison - shouldn't you try to level the computing capacity field? Or at least limit how much energy each "player" is allowed to use (and then let each team optimize…

Knowing that AlphaZero beat Stockfish 8 (28 wins, 0 losses, and 72 draws), what would AlphaZero's rating be?

I found three different questions here on SEC that asked what Stockfish 8's rating was for the match against AlphaZero, but none that asked what AlphaZero's rating should have been after (if it had been in a rated event, and assuming that it…

Lecture/Book on AlphaGo/AlphaZero

I am very interested in how AlphaGo resp. AlphaZero works. It seems to me, the related Google Papers are very dense and not easy to read. Is there any textbook or lecture that explains on a technical level how it all works? I.e. starting with neural…
