[ad_1] Rock-paper-scissors, or RPS, may seem like a simple and random game. However, there is actually a science behind it, and that science extends to the world rankings of the game. In this article, we’ll break down the algorithm behind RPS world rankings and explain how it works.

First, let’s explain what RPS world rankings are. RPS world rankings are a system used to rank the best RPS players from around the globe. It works by assigning points to players based on their performance in RPS tournaments. The more tournaments a player participates in and the better they do, the more points they earn. The players with the most points are ranked higher on the world rankings.

Now, let’s dive into the algorithm behind RPS world rankings. The algorithm used is the Glicko rating system, which was created by Professor Mark Glickman in the late 1990s. The Glicko system is similar to the Elo rating system used in chess, but it takes into account more factors to make it more accurate.

The Glicko system takes three factors into account: rating, volatility, and rating period. The rating is a player’s skill level, and it starts at 1500 for new players. The volatility measures the uncertainty in a player’s rating, and it changes based on how often a player competes and how well they do. Lastly, the rating period measures how long it’s been since a player’s rating was updated.

To calculate the world rankings, the Glicko system looks at a player’s rating, volatility, and rating period, along with the results of their matches. The system factors in the ratings of both the player and their opponent, as well as the expected outcome based on those ratings. If a player beats an opponent with a higher rating, they will earn more points than if they beat an opponent with a lower rating.

It’s worth noting that the Glicko system also takes into account the number of players in a tournament and the level of competition. If a player wins a tournament with a large number of skilled players, they will earn more points than if they win a tournament with fewer skilled players.

So, why is all this important? Well, RPS world rankings may just be a fun way to measure skill in a game, but the algorithm behind it could have broader applications. The Glicko system could be used to rank players in other games or even in other areas, such as the workplace or academia. It’s a way to objectively measure skill and promote fair competition.

In conclusion, RPS world rankings are not just about who wins the most games. There is a complex algorithm behind it that takes into account a player’s skill level, uncertainty, and time since their rating was last updated. The Glicko system is a reliable way to measure skill in a game and could have broader applications in other areas. So, next time you play RPS, remember that there’s some serious science behind it![ad_2]
