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…
Learning to coordinate in a complex and non-stationary world
M. Marsili, R. Mulet, F. Ricci-Tersenghi +1
We study analytically and by computer simulations a complex system of adaptive agents with finite memory. Borrowing the framework of the Minority Game and using the replica formali…
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…
First order phase transition in a nonequilibrium growth process
Lorenzo Giada, Matteo Marsili
We introduce a simple continuous model for nonequilibrium surface growth. The dynamics of the system is defined by the KPZ equation with a Morse-like potential representing a short…
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…
