Crowd-Anticrowd Theory of Multi-Agent Minority Games
Michael L. Hart, Neil F. Johnson
We present a formal treatment of the Crowd-Anticrowd theory of Minority Games played by a population of competing agents. This theory is built around a description of the crowding…
Managing catastrophic changes in a collective
David Lamper, Paul Jefferies, Michael Hart +1
We address the important practical issue of understanding, predicting and eventually controlling catastrophic endogenous changes in a collective. Such large internal changes arise…
Crash Avoidance in a Complex System
Michael L. Hart, David Lamper, Neil F. Johnson
Complex systems can exhibit unexpected large changes, e.g. a crash in a financial market. We examine the large endogenous changes arising within a non-trivial generalization of the…
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…
Trader dynamics in a model market
Neil F. Johnson, Michael Hart, Pak Ming Hui +1
We explore various extensions of Challet and Zhang's Minority Game in an attempt to gain insight into the dynamics underlying financial markets. First we consider a heterogeneous p…
