Stockfish vs alphazero

In late experiments, it quickly demonstrated itself superior to any technology that we would otherwise consider leading-edge. That being said it seems to me that Magnus has started winning with black more often than previously.

It may have been an anomaly or a short term trend just something that stood out to me at the time. In retrospect I may have been or may now be conflating decided games with their scoring, as it has been a few years. I'm satisfied that the first move advantage is a reality and not by and large an artifact of human psychology.

Truly engines are what convinces me the most, as they are not named DeepFreud or StockJung after all. Sometimes my biting sarcasm comes across as more mean spirited than it really is intended. Could be a data transmission anomaly. So if I give you grief about your authorship of some of the lengthiest novels on cg.

I might even have un-diagnosed tourette syndrome? My coworker friend John said I can't believe what you say over the radio, to which I quipped you should hear what I don't say Thanks again Go Alpha Zero!!! It features an absolutely astounding game, also covered in an agadmator video. Kramnik's aim appears to be to "find a chess variant that would not only have the potential to bring the excitement and decisive victories back to chess, but is also aesthetically pleasing.

The game results data from chess data bases such as ChessTempo show that for players at all rating levels White wins The use of AlphaZero to support his aim seems like an overkill to me, requiring not only access to AlphaZero and its required TPUs but also to a training session to modify AlphaZero's neural net's weights and biases to reflect the deletion of the castling rules.

In contrast, modifying Stockfish 11 seems like only a 1-line change in the types. Then you can run Stockfish 11NS no castling against Stockfish 11NS games at your heart's content and see if there is a significant change in the number of decisive games at various time controls without the castling options compared to the number of decisive games at various time controls with the castling options But I do like his concept, and it would be nice to see if someone is sufficiently interested in making that modification to Stockfish 11 and running a sufficient number of Stockfish 11NS vs.

Stockfish 11NS tournaments to see what the increase in the number of decisive games actually is. I do have thoughts about these things but not a lot of time to post in sufficient depth to get them across.

But do check out the two games that he annotates, they are something else. And re-reading my post I saw multiple references to my hypothetical Stockfish 11NS which I even identified as no castling!

It obviously should have been Stockfish 11NC. And I can't even blame the keyboard since the letter "C", while close, is not adjacent to the letter "S", and us touch typists would be pressed with a different finger. I must have had a bad day. And when you do have time please post your thoughts. I would be interested in them. It was very interesting to see how AlphaZero, as Black, tries to counter it's own approach! And about Kramnik's remark in game 1 about I've seen AlphaZero's Ke1-f1 in other games, whether forced or not.

After all, once the h-pawn is pushed, the rook belongs on h1 to support its advance and take advantage of any possible opening of the h-file. And both sides have to do something about providing additional safety to their kings.

Black's Ke7 in game 2 is another example of trying to do that, but somewhat more dramatic as it exposes Black's king to White's pressure on the e-file. It made me think that perhaps Black should have played Kf8 instead of AlphaZero won the closed-door, game match with 28 wins, 72 draws, and zero losses. Put more plainly, AlphaZero was not "taught" the game in the traditional sense. That means no opening book, no endgame tables, and apparently no complicated algorithms dissecting minute differences between center pawns and side pawns.

Google headquarters in London from inside, with the DeepMind section on the eighth floor. This would be akin to a robot being given access to thousands of metal bits and parts, but no knowledge of a combustion engine, then it experiments numerous times with every combination possible until it builds a Ferrari.

That's all in less time that it takes to watch the "Lord of the Rings" trilogy. The program had four hours to play itself many, many times, thereby becoming its own teacher.

For now, the programming team is keeping quiet. They chose not to comment to Chess. Hassabis, who played in the ProBiz event of the London Chess Classic, is currently at the Neural Information Processing Systems conference in California where he is a co-author of another paper on a different subject. One person that did comment to Chess.

Indeed, much like humans, AlphaZero searches fewer positions that its predecessors. The paper claims that it looks at "only" 80, positions per second, compared to Stockfish's 70 million per second. As he told Chess. I feel now I know. We also learned, unsurprisingly, that White is indeed the choice, even among the non-sentient. The machine also ramped up the frequency of openings it preferred. Sorry, King's Indian practitioners, your baby is not the chosen one.

The French also tailed off in the program's enthusiasm over time, while the Queen's Gambit and especially the English Opening were well represented. Frequency of openings over time employed by AlphaZero in its "learning" phase.

What do you do if you are a thing that never tires and you just mastered a year-old game? You conquer another one. After the Stockfish match, AlphaZero then "trained" for only two hours and then beat the best Shogi-playing computer program "Elmo. But obviously the implications are wonderful far beyond chess and other games. The ability of a machine to replicate and surpass centuries of human knowledge in complex closed systems is a world-changing tool.

A video compilation of their thoughts will be posted on the site later. The player with most strident objections to the conditions of the match was GM Hikaru Nakamura. While a heated discussion is taking place online about processing power of the two sides, Nakamura thought that was a secondary issue.

The American called the match "dishonest" and pointed out that Stockfish's methodology requires it to have an openings book for optimal performance. While he doesn't think the ultimate winner would have changed, Nakamura thought the size of the winning score would be mitigated. GM Larry Kaufmanlead chess consultant on the Komodo program, hopes to see the new program's performance on home machines without the benefits of Google's own computers.

He also echoed Nakamura's objections to Stockfish's lack of its standard opening knowledge. What isn't yet clear is whether AlphaZero could play chess on normal PCs and if so how strong it would be. It may well be that the current dominance of minimax chess engines may be at an end, but it's too soon to say so. It should be pointed out that AlphaZero had effectively built its own opening book, so a fairer run would be against a top engine using a good opening book.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

AI Is Now the Undisputed Champion of Computer Chess

We can't say for sure since AlphaZero is a private engine, i. Still, if AlphaZero hasn't improved since it was unveiled, it will likely lose to the latest version of Stockfish. The latest versions of Stockfish are capable of beating Stockfish 8 by about elo see also this.

It's true that elo isn't transitive i. You ask about Stockfish 10 not latest Stockfishwhich still beats Stockfish 8 by elo, so it should be capable of beating AlphaZero as well.

It incorporates many new innovations not in the original paper, and therefore should be stronger than AlphaZero. Indications are it's competitive with Stockfish, and for now at least stronger: it won the most recent version of the Top Chess Engine Championship by five games - an elo difference of about You might be interested in the ongoing Season 18 of the Top Chess Engine Championship, live games are available here.

Leela is at least competitive with Stockfish, and there's a good chance it's stronger right now as well.

Ask Question. Asked 1 month ago. Active 1 month ago.AlphaZero is a computer program developed by artificial intelligence research company DeepMind to master the games of chessshogi and go. This algorithm uses an approach similar to AlphaGo Zero. On December 5,the DeepMind team released a preprint introducing AlphaZero, which within 24 hours of training achieved a superhuman level of play in these three games by defeating world-champion programs Stockfishelmoand the 3-day version of AlphaGo Zero.

In each case it made use of custom tensor processing units TPUs that the Google programs were optimized to use. After four hours of training, DeepMind estimated AlphaZero was playing at a higher Elo rating than Stockfish 8; after 9 hours of training, the algorithm defeated Stockfish 8 in a time-controlled game tournament 28 wins, 0 losses, and 72 draws. Comparing Monte Carlo tree search searches, AlphaZero searches just 80, positions per second in chess and 40, in shogi, compared to 70 million for Stockfish and 35 million for elmo.

AlphaZero compensates for the lower number of evaluations by using its deep neural network to focus much more selectively on the most promising variation. AlphaZero was trained solely via self-play, using 5, first-generation TPUs to generate the games and 64 second-generation TPUs to train the neural networks. In parallel, the in-training AlphaZero was periodically matched against its benchmark Stockfish, elmo, or AlphaGo Zero in brief one-second-per-move games to determine how well the training was progressing.

DeepMind judged that AlphaZero's performance exceeded the benchmark after around four hours of training for Stockfish, two hours for elmo, and eight hours for AlphaGo Zero.

Stockfish was allocated 64 threads and a hash size of 1 GB, [1] a setting that Stockfish's Tord Romstad later criticized as suboptimal. In games from the normal starting position, AlphaZero won 25 games as White, won 3 as Black, and drew the remaining AlphaZero was trained on shogi for a total of two hours before the tournament.

DeepMind stated in its preprint, "The game of chess represented the pinnacle of AI research over several decades. State-of-the-art programs are based on powerful engines that search many millions of positions, leveraging handcrafted domain expertise and sophisticated domain adaptations.

However, some grandmasters, such as Hikaru Nakamura and Komodo developer Larry Kaufmandownplayed AlphaZero's victory, arguing that the match would have been closer if the programs had access to an opening database since Stockfish was optimized for that scenario. Similarly, some shogi observers argued that the elmo hash size was too low, that the resignation settings and the "EnteringKingRule" settings cf. Papers headlined that the chess training took only four hours: "It was managed in little more than the time between breakfast and lunch.

It's also very political, as it helps make Google as strong as possible when negotiating with governments and regulators looking at the AI sector. Human chess grandmasters generally expressed excitement about AlphaZero. Grandmaster Hikaru Nakamura was less impressed, and stated "I don't necessarily put a lot of credibility in the results simply because my understanding is that AlphaZero is basically using the Google supercomputer and Stockfish doesn't run on that hardware; Stockfish was basically running on what would be my laptop.

If you wanna have a match that's comparable you have to have Stockfish running on a supercomputer as well. Top US correspondence chess player Wolff Morrow was also unimpressed, claiming that AlphaZero would probably not make the semifinals of a fair competition such as TCEC where all engines play on equal hardware.

stockfish vs alphazero

Morrow further stated that although he might not be able to beat AlphaZero if AlphaZero played drawish openings such as the Petroff DefenceAlphaZero would not be able to beat him in a correspondence chess game either. This gap is not that high, and elmo and other shogi software should be able to catch up in 1—2 years. DeepMind addressed many of the criticisms in their final version of the paper, published in December in Science.

Instead of a fixed time control of one move per minute, both engines were given 3 hours plus 15 seconds per move to finish the game. In a game match, AlphaZero won with a score of wins to 6 losses, with the rest drawn. AlphaZero won Human grandmasters were generally impressed with AlphaZero's games against Stockfish. In the chess community, Komodo developer Mark Lefler called it a "pretty amazing achievement", but also pointed out that the data was old, since Stockfish had gained a lot of strength since January when Stockfish 8 was released.

Kaufman argued that the only advantage of neural network—based engines was that they used a GPU, so if there was no regard for power consumption e. Based on this, he stated that the strongest engine was likely to be a hybrid with neural networks and standard alpha—beta search. Leela contested several championships against Stockfish, where it showed similar strength.

In DeepMind published MuZero, a unified system that played excellent chess, shogi, and go, as well as games in the Atari Learning Environment, without being pre-programmed with their rules.It was a war of titans you likely never heard about. On one side was Stockfish 8. This world-champion program approaches chess like dynamite handles a boulder—with sheer force, churning through 60 million potential moves per second.

That algorithm values a delicate balance of factors like pawn positions and the safety of its king. But AlphaZero is an entirely different machine. Its programmers merely tuned it with the basic rules of chess and allowed it to play several million games against itself. As it learned, AlphaZero gradually pieced together its own strategy.

The head-to-head battle was astonishing. In games, AlphaZero never lost. The AI engine won the match winning 28 games and drawing the rest with dazzling sacrifices, risky moves, and a beautiful style that was completely new to the world of computer chess.

Mainly, that AlphaZero has already lost one on the g file, and is sacrificing yet another with this jumpy rook move. Run this position though many advanced chess engines, and most will tell you that with the sacrificed pieces, AlphaZero is now losing. So why is it doing this? Eventually AlphaZero is going to fill the gaps left by the missing pawns with rooks, like a double-barrel shotgun.

Those pawns, AlphaZero apparently believes, are worth less than the opportunity to assault the king from even more directions.

By move 42, AlphaZero has sacrificed even more pawns, and is marching another poor, disposable sucker toward oblivion. Its queen is one leap away from the fray. Type keyword s to search. Today's Top Stories.

The results leave no question, once again, that AlphaZero plays some of the strongest chess in the world. See below for three sample games from this match with analysis by Stockfish 10 and video analysis by GM Robert Hess. AlphaZero also bested Stockfish in a series of time-odds matches, soundly beating the traditional engine even at time odds of 10 to one. The pre-release copy of journal article, which is dated Dec.

The machine-learning engine also won all matches against "a variant of Stockfish that uses a strong opening book," according to DeepMind. Adding the opening book did seem to help Stockfish, which finally won a substantial number of games when AlphaZero was Black—but not enough to win the match.

AlphaZero's results wins green, losses red vs the latest Stockfish and vs Stockfish with a strong opening book. Image by DeepMind via Science. The 1,game match was played in early In the match, both AlphaZero and Stockfish were given three hours each game plus a second increment per move. This time control would seem to make obsolete one of the biggest arguments against the impact of last year's match, namely that the time control of one minute per move played to Stockfish's disadvantage.

With three hours plus the second increment, no such argument can be made, as that is an enormous amount of playing time for any computer engine. In the time odds games, AlphaZero was dominant up to to-1 odds. Stockfish only began to outscore AlphaZero when the odds reached to AlphaZero's results wins green, losses red vs Stockfish 8 in time odds matches. AlphaZero's results in the time odds matches suggest it is not only much stronger than any traditional chess engine, but that it also uses a much more efficient search for moves.

According to DeepMind, AlphaZero uses a Monte Carlo tree search, and examines about 60, positions per second, compared to 60 million for Stockfish. An illustration of how AlphaZero searches for chess moves. What can computer chess fans conclude after reading these results?

AlphaZero has solidified its status as one of the elite chess players in the world. But the results are even more intriguing if you're following the ability of artificial intelligence to master general gameplay.

According to the journal article, the updated AlphaZero algorithm is identical in three challenging games: chess, shogi, and go. This version of AlphaZero was able to beat the top computer players of all three games after just a few hours of self-training, starting from just the basic rules of the games. The updated AlphaZero results come exactly one year to the day since DeepMind unveiled the first, historic AlphaZero results in a surprise match vs Stockfish that changed chess forever.

Since then, an open-source project called Lc0 has attempted to replicate the success of AlphaZero, and the project has fascinated chess fans. Lc0 now competes along with the champion Stockfish and the rest of the world's top engines in the ongoing Chess. CCC fans will be pleased to see that some of the new AlphaZero games include "fawn pawns," the CCC-chat nickname for lone advanced pawns that cramp an opponent's position. Perhaps the establishment of these pawns is a critical winning strategy, as it seems AlphaZero and Lc0 have independently learned it.
