Scientists in China have found patterns in the age old game of Rock-Paper-Scissors employed by players. Scientists found that, most players play with the about the same number of frequency of rock paper and scissors in a game, with each ‘weapon’ appearing 1/3 of the time. However, they found that when a player wins, they will tend to stay with the ‘weapon’ that they are having success with. The scientists argue that the best ‘move’ for a player to make during a game is to chose with random. By using game theory, the scientists found that the best chance to win is presented when a player chooses a ‘weapon’ at random. When not chosen at random, players create a pattern that can be recognized and exploited by other players. All in all it is an interesting article regarding the game that everyone knows how to play.
