It doesn't stand for anything at all, because it's not an acronym. It should be "Elo" rather than "ELO." The Elo rating system is named after the Hungarian-American physics professor (and 8-time state champion chess master) Arpad Elo, who originally devised his rating system around 1960.

Page 5 in the paper has your answer: ... AlphaZero compensates for the lower number of evaluations by using its deep neural network to costs much more selectively on the most promising variations - arguably a more "human-like" approach to chess ... "selectively" is the key word. What does that mean? Let's use this following position for our example: ...

No difference whatsoever. As with tournament results, ELO (or Glicko, or any other chess rating system) counts all losses the same, all draws the same, and all wins the same. Doesn't matter if you lose on time, resign, or get mated on the board --- nor whether it took 12 moves or 120. Likewise a draw is a draw, whether by agreement, repetition, stalemate (...

ELO is not an absolute measurement; it is only meaningful relevant to the ELOs of other players. This is because it is only calculated based on performance against other rated players. The "Maximum ELO", which seems to be what you're looking for, is therefore equal to the ELO of a player at such a time when his ELO is so high that he cannot gain any ELO ...

There are actually three different distinctions in the USCF system that have to do with a 2200 rating. First is the National Master title. It is awarded to anyone who has ever had an established (not provisional) rating of over 2200. Once a player is a National Master, they have the title for life no matter what happens to their rating. The NM title has no ...

The Site ratings at slow time controls can be quite reliable for servers where strong players congregate (ICC, FICS to name a few) as the ratings VERY closely reflect your true playing strength if you've played enough games. For very standardized rating systems such as USCF and FIDE/ELO, you will notice that the different rating classes tend to point to the ...

Most strong engines emphasize looking very deeply, at the expense of having a superficial evaluation function. In the AlphaZero paper, they say that Stockfish looks at 70 million positions per second. Human grandmasters look at very few positions indeed compared to engines, but they have a better feeling who is better in a given position. AlphaZero looked ...

Short answer: Neither Elo-ratings are not ajusted for calculation after each game, they are not adjusted after each tournament either. For all games played during one month, each player is supposed to have his last published elo-rating. If I am 2300 on the 1st of November and we play together November the 29th, your rating will be calculated by ...

Right at the bottom of the Computer Chess Rating List for the 40/4 time control is Brutus RND, an engine that simply selects random legal moves. http://www.computerchess.org.uk/ccrl/404/cgi/engine_details.cgi?print=Details&each_game=1&eng=Brutus%20RND#Brutus_RND It has a rating of 205 (as of 6/6/2018). This is not a FIDE rating of course, but it is ...

The best thing to train is (almost) always calculation: Get a set of maybe 1000 3-5 move combinations and go through those problems until you basically know them by heart. That's to enable pattern recognition. Apart from that set, concentrate on calculating long variations in your training instead of just seeing tactical shots. The Yusupov books are a good ...

This answer addresses one concrete portion of the OP; namely, for an arbitrary N > 0, what rating difference between Player A and Player B corresponds to Player A's expected score against Player B being N times the expected score for Player B? I'll speak in terms of the USCF's Elo rating system, since I'm most familiar with it. If Player A's expected ...

AlphaZero already seems to play like a regular "centaur" -> correspodence GM with an engine assistance. As an FM I'd get much more enjoyment of playing AlphaZero vs a regular engine. One comparison would be it plays like Karpov would with perfect tactics. (Game 9 AlphaZero plays a piece down for 15moves which is very Tal like). It is not just style, ...

You should try it. Over the board chess is a very different experience, the social aspect is a lot of fun and the level of concentration required very different from online. Also there is no better way to improve your chess than discussing a game with your opponent afterwards. It appears you're talking about "Skakklubben 1968" in Århus, Denmark. It appears ...

First, note that the final ratings depend entirely on the score of the match, not on the particular games. For example, if they each win a game, their ratings will change by the same amount as if they draw both games. This may seem like a coincidence but it's just a consequence of the way that FIDE ratings work. Here is the entire table of possible results. ...

State of the art chess engines will win every game against an amateur, so they won't tell much about your playing level. On the other hand, the engines of sensible strength (or a handicapped engine or similar) I've tried do not emulate human playing at amateur levels well. While there are stronger and weaker engines and most probably you will find an engine ...

Even if it is not available, something like this is not too hard to implement yourself. Here is an example with extremely silly and simple rating system that is just meant to give you an idea. But I don't think that using actual Elo formula that much harder. EDIT: I edit my implementation to use Elo formula (not including floors) given by the formula here ...

It does take awhile for FIDE to update their ratings, which is monthly (see article) compared to the unofficial Live ratings site at Live Ratings. But it is interesting to note that Carlsen is due for a 2 point bump according to the Live rating site.

There is one (and so far only one) place where you can get the official FIDE rating - the FIDE Online Arena. It however needs a client. A quick introduction is here and the arena is at http://arena.fide.com I have not tried it so I cannot comment on how good the interface is but I assume it is good. The killer feature is that it calculates official FIDE ...

According to the list downloaded here, there are currently 261782 players with a FIDE rating. I wrote a small program to analyze it, and here are the results: ------------------------- Rating Number of players 2800+ 5 2750+ 18 2700+ 43 2650+ 114 2600+ 262 2550+ 514 2500+ 921 2450+ 1641 2400+ 3130 2350+ 5223 2300+ 8669 2250+ 13791 ...

I'm the author of zurichess, the engine mentioned in your post. Here are, what I think, the most important things to get your engine to play +2000ELO. If it the terminology is not clear check https://chessprogramming.wikispaces.com/ which is one of the best resources available. Write a move generator. Make sure it's correct and passes all perft tests. Don't ...

It is as easy to jump on a bandwagon saying Alpha-Zero's play is 'more' human than previous computer chess programs as it is to jump on the opposite wagon and say Alpha-Zero's play is entirely 'alien'. It's not clear that Alpha-zero's play is 'more human' especially given our human tendency towards anthropomorphism. Chess as a Struggle of the (human) Mind ...

This is extremely hard to say, because the initial position is probably a draw. Besides playing perfectly, the computer also has to set problems for the opponent. If the position is a draw, then there may be fifteen different moves that don't lose. The computer will have no reason to prefer one over another, so perhaps it'll just decide to drop a pawn or so ...

The average Elo rating of the e.g. top 10 players in the world is rising every year. I think that the relative distance between the number one rated player and the other 9 players in the top 10 becomes relevant in this context. This distance can be estimated by subtracting the average of the ratings of the 9 players (ranked 2-10 in the world) from the rating ...

There actually is an ambitiously worked out answer out there: http://web.ist.utl.pt/diogo.ferreira/papers/ferreira13impact.pdf On page 77 you get the relevant table: depth: elo: 20 2894 19 2828 18 2761 17 2695 16 2629 15 2563 … So my comment was slightly off, depth 20 is already very strong. Still the point remains, that it is ...

I am 2300-2450 on lichess blitz, while my FIDE rating is 2300-2350. There is a correlation but there is a large body of players on lichess that are not FIDE rated.

No, Elo ratings have no theoretical limit. If Alice scored 76% against Carlsen (rating 2853) consistently, she would stabilize at a rating of 3053*, and if Bob scored 76% against Alice, he would stabilize at a rating of 3253**, etc. There is no theoretical end to this sequence. However, consensus seems to be that in practice a perfect player would have a ...

One important thing is to identify possible weaknesses in your play. It depends a lot on you. A coach can sometimes identify serious weaknesses, which, if corrected, can result in a bumb up in results. I would disagree with BlindKungFuMaster about ignoring the opening and endgame. Endgame study has a high time invested-to-wins ratio. Your chance of getting ...

Well, the main problem with these tests is that they aren't reliable. They can only give you a rough indication of your playing strength, nothing more. Maybe something accurate to 100 rating points, and it's very hard to gain 100 points in a month, even for a beginner. So it will be hard to measure your progress on that scale. Also, taking the same test ...

OK, so the tournament was the Rattenberger Schnellschach-Open 2019 Tiroler Einzelmeisterschaft im Schnellschach It was a Swiss tournament. Here are your results from the tournament.
