Editing ELO rating (section)

== ELO Rating ==
ELO rating is a numerical rating system used to assess the relative strength of players in games such as chess, Go, backgammon, poker, and more. Each player has their own ELO rating, which is initially set at a certain level and changes based on the results of their games.

The main idea behind the ELO rating is that players gain or lose rating points based on the strength of their opponent and the outcome of the match. If a stronger player defeats a weaker player, they will gain fewer points compared to if they had won against a stronger opponent. Conversely, if a weaker player defeats a stronger player, they will gain more points than if they had won against a weaker opponent.

The coefficient K is also used to determine how much the player's rating will change after each match. The value of K can vary for different games and may depend on the player's level, the number of games played, and other factors.

Overall, the ELO rating system allows players to compare their strength against other players, and it is widely used in both sports and computer games.
