Second, established and higher-rated players have a lower K-factor. Rating floors in the United States work by guaranteeing that a player will never drop below a certain limit.
This also combats deflation, but the chairman of the USCF Ratings Committee has been critical of this method because it does not feed the extra points to the improving players.
A possible motive for these rating floors is to combat sandbagging, i. Human—computer chess matches between Deep Blue versus Garry Kasparov and demonstrated that chess computers are capable of defeating even the strongest human players.
However, chess engine ratings are difficult to quantify, due to variable factors such as the time control and the hardware the program runs on.
Published engine rating lists such as CCRL are based on engine-only games on standard hardware configurations and are not directly comparable to FIDE ratings.
The Elo rating system is used in the chess portion of chess boxing. In order to be eligible for professional chess boxing, one must have an Elo rating of at least , as well as competing in 50 or more matches of amateur boxing or martial arts.
American college football used the Elo method as a portion of its Bowl Championship Series rating systems from to after which the BCS was replaced by the College Football Playoff.
The use of rating systems was effectively scrapped with the creation of the College Football Playoff in ; participants in the CFP and its associated bowl games are chosen by a selection committee.
In other sports, individuals maintain rankings based on the Elo algorithm. These are usually unofficial, not endorsed by the sport's governing body.
The World Football Elo Ratings is an example of the method applied to men's football. It is the official rating system of major organizations such as the Intercollegiate Tennis Association and World TeamTennis and is frequently used in segments on the Tennis Channel.
The algorithm analyzes more than 8 million match results from over , tennis players worldwide. On May 8, , Rafael Nadal — having won 46 consecutive sets in clay court matches — had a near-perfect clay UTR of One of the few Elo-based rankings endorsed by a sport's governing body is the FIFA Women's World Rankings , based on a simplified version of the Elo algorithm, which FIFA uses as its official ranking system for national teams in women's football.
In , Nate Silver, editor-in-chief of the statistical commentary website FiveThirtyEight , and Reuben Fischer-Baum produced Elo ratings for every National Basketball Association team and season through the season.
An Elo-based ranking of National Hockey League players has been developed. National Scrabble organizations compute normally distributed Elo ratings except in the United Kingdom , where a different system is used.
The North American Scrabble Players Association has the largest rated population of active members, numbering about 2, as of early Lexulous also uses the Elo system.
New players are assigned a rating of , with the best humans and bots rating over VogClub sets a new player's rating at Despite questions of the appropriateness of using the Elo system to rate games in which luck is a factor, trading-card game manufacturers often use Elo ratings for their organized play efforts.
However, the DCI abandoned this system in in favour of a new cumulative system of "Planeswalker Points", chiefly because of the above-noted concern that Elo encourages highly rated players to avoid playing to "protect their rating".
Similarly, Decipher, Inc. The Esports game Overwatch , the basis of the unique Overwatch League professional sports organization , uses a derivative of the Elo system to rank competitive players with various adjustments made between competitive seasons.
Nevertheless, it is common for players of ranked video games to refer to all ratings as an Elo. According to Lichess, the Elo system is outdated even by chess standards, with Glicko-2 now being used by a significant number of chess organisations.
Various online games use Elo ratings for player-versus-player rankings. Since , Golden Tee Live has rated players based on the Elo system.
New players start at , with top players rating over The initial K-value was 30, but was changed to 5 in January , then changed to 15 in July Roblox introduced the Elo rating in The browser game Quidditch Manager uses the Elo rating to measure a team's performance.
RuneScape 3 was to use the Elo system for the rerelease of bounty hunter in In  [ circular reference ] an online gaming ladder called Clanbase  was launched, who used the Elo scoring system to rank teams.
The site later went offline in The Elo rating system has been used in soft biometrics ,  which concerns the identification of individuals using human descriptions.
Comparative descriptions were utilized alongside the Elo rating system to provide robust and discriminative 'relative measurements', permitting accurate identification.
The Elo rating system has also been used in biology for assessing male dominance hierarchies,  and in automation and computer vision for fabric inspection.
Moreover, online judge sites are also using Elo rating system or its derivatives. For example, Topcoder is using a modified version based on normal distribution,  while Codeforces is using another version based on logistic distribution.
Elo rating system has also been noted in dating apps, such as in the matchmaking app Tinder , which uses a variant of the Elo rating system. The Elo rating system was featured prominently in The Social Network during the algorithm scene where Mark Zuckerberg released Facemash.
In the scene Eduardo Saverin writes mathematical formulas for the Elo rating system on Zuckerberg's dormitory room window.
Behind the scenes, the movie claims, the Elo system is employed to rank girls by their attractiveness. The equations driving the algorithm are shown briefly, written on the window;  however, they are slightly incorrect.

Apr 9, Apr 10, Sep 26, Feb 23, First of all, let's not pretend chess players don't care about ratings.
We do. Mar 17, Apr 17, May 10, Log In or Join. For example, the higher rated players, being much more selective in who they play, results often in those players lurking around, just waiting for "overvalued" opponents to try and challenge.
Such players because of rating concerns, may feel discouraged of course from playing any significantly lower rated players again for rating concerns.
The agenda of points scoring can interfere with playing with abandon, and just for fun. Interesting from the perspective of preserving high Elo ratings versus promoting rated game activity is a recent proposal by British Grandmaster John Nunn regarding qualifiers based on Elo rating for a World championship model.
Nunn highlights in the section on "Selection of players", that players not only be selected by high Elo ratings, but also their rated game activity.
Nunn clearly separates the "activity bonus" from the Elo rating, and only implies using it as a tie-breaking mechanism.
The Elo system when applied to casual online servers has at least two other major practical issues that need tackling when Elo is applied to the context of online chess server ratings.
These are engine abuse and selective pairing. The first and most significant issue is players making use of chess engines to inflate their ratings.
This is particularly an issue for correspondence chess style servers and organizations, where making use of a wide variety of engines within the same game is entirely possible.
This would make any attempts to conclusively prove that someone is cheating quite futile. Blitz servers such as the Free Internet Chess Server or the Internet Chess Club attempt to minimize engine bias by clear indications that engine use is not allowed when logging on to their server.
A more subtle issue is related to pairing. When players can choose their own opponents, they can choose opponents with minimal risk of losing, and maximum reward for winning.
Such a luxury of being able to hand-pick your opponents is not present in Over-The-board Elo type calculations, and therefore this may account strongly for the ratings on the ICC using Elo which are well over In the category of choosing over-rated opponents, new-entrants to the rating system who have played less than 50 games are in theory a convenient target as they may be overrated in their provisional rating.
The ICC compensates for this issue by assigning a lower K-factor to the established player if they do win against a new rating entrant. The K-factor is actually a function of the number of rated games played by the new entrant.
Elo therefore must be treated as a bit of fun when applied in the context of online server ratings. Indeed the ability to choose one's own opponents can have great fun value also for spectators watching the very highest rated players.
For example they can watch very strong GM's challenge other very strong GMs who are also rated over for example. Such opposition which the highest level players online would play in order to maintain their rating, would often be much stronger opponents than if they did play in an Open tournament which is run by Swiss pairings.
Additionally it does help ensure that the game histories of those with very high ratings will often be with opponents of similarly high level ratings.
Elo ratings online therefore still provides a useful mechanism for providing a rating based on the opponent's rating. Its overall credibility however, needs to be seen in the context of at least the above two major issues described — engine abuse, and selective pairing of opponents.
The ICC has also in recent times introduced "auto-pairing" ratings which are based on random pairings, but with each win in a row ensuring a statistically much harder opponent who has also won x games in a row.
With potentially hundreds of players involved, this creates some of the challenges of a major large Swiss event which is being fiercely contested, with round winners meeting round winners.
This approach to pairing certainly maximizes the rating risk of the higher-rated participants, who may face very stiff opposition from players below for example.
This is a separate rating in itself, and is under "1-minute" and "5-minute" rating categories. Maximum ratings achieved over are exceptionally rare.
There are three main mathematical concerns relating to the original work of Professor Elo, namely the correct curve, the correct K-factor, and the provisional period crude calculations.
They found that this did not accurately represent the actual results achieved by particularly the lower rated players. Instead they switched to a logistical distribution model, which seemed to provide a better fit for the actual results achieved.
The second major concern is the correct "K-factor" used. If the K-factor coefficient is set too large, there will be too much sensitivity to winning, losing or drawing, in terms of the large number of points exchanged.
Too low a K-value, and the sensitivity will be minimal, and it would be hard to achieve a significant number of points for winning, etc. Elo's original K-factor estimation, was based without the benefit of huge databases and statistical evidence.
Sonas indicates that a K-factor of 24 for players rated above may be more accurate both as a predictive tool of future performance, and also more sensitive to performance.
Certain Internet chess sites seem to avoid a three-level K-factor staggering based on rating range. The USCF which makes use of a logistic distribution as opposed to a normal distribution have staggered the K-factor according to three main rating ranges of:.
In over-the-board chess, the staggering of K-factor is important to ensure minimal inflation at the top end of the rating spectrum. In theory, it would make it harder for players to get the much higher ratings, if their K-factor sensitivity was lessened from 32 to 16 for example, when they get over rating.
This would seem to hold true, for example, if one analysed the games of a GM on the ICC: one can find a string of games of opponents who are all over A category 10 FIDE event would mean players are restricted in rating between to However, if the player entered normal Swiss-paired open over-the-board chess tournaments, he would likely meet many opponents less than FIDE on a regular basis.
The K-factor would arguably only slow down the increases that the player achieves after each win. The evidence given in the ICC K-factor article relates to the auto-pairing system, where the maximum ratings achieved are seen to be only about In other sports, individuals maintain rankings based on the Elo algorithm.
