Stochastic strategies in the Minority Game
M. Hart, P. Jefferies, N. F. Johnson +1
We show analytically how the fluctuations (i.e. standard deviation) in the Minority Game (MG) can decrease below the random coin-toss limit if the agents use more general, stochast…

Crowd-anticrowd model of the Minority Game
M. Hart, P. Jefferies, N. F. Johnson +1
We provide a theoretical description of the Minority Game in terms of crowd effects. The size of the fluctuations arising in the game is controlled by the interplay between crowds…
