Dynamical instabilities in a simple minority game with discounting
Damien Challet, Andrea De Martino, Matteo Marsili
We explore the effect of discounting and experimentation in a simple model of interacting adaptive agents. Agents belong to either of two types and each has to decide whether to pa…
Minority games with finite score memory
Damien Challet, Andrea De Martino, Matteo Marsili +1
We analyze grand-canonical minority games with infinite and finite score memory and different updating timescales (from `on-line' games to `batch' games) in detail with various com…
Continuum time limit and stationary states of the Minority Game
M. Marsili, D. Challet
We discuss in detail the derivation of stochastic differential equations for the continuum time limit of the Minority Game. We show that all properties of the Minority Game can be…
Comment on: Thermal model for Adaptive Competition in a Market
D. Challet, M. Marsili, R. Zecchina
We show that the dynamical equations describing the collective behavior of the model introduced by Cavagna et al. i) are not their Eqs. (5,6) but rather ii) are the same as those o…
Relevance of memory in Minority Games
Damien Challet, Matteo Marsili
By considering diffusion on De Bruijn graphs, we study in details the dynamics of the histories in the Minority Game, a model of competition between adaptative agents. Such graphs…
Phase Transition and Symmetry Breaking in the Minority Game
Damien Challet, Matteo Marsili
We show that the Minority Game, a model of interacting heterogeneous agents, can be described as a spin systems and it displays a phase transition between a symmetric phase and a s…
