This paper surveys the emerging science of how to design a``COllective
INtelligence''(COIN). A COIN is a large multi-agent system where:(i) There is little to no …

Demand outstrips available resources in most situations, which gives rise to competition,
interaction and learning. In this article, we review a broad spectrum of multi-agent models of …

Due to the increasing sophistication and miniaturization of computational components,
complex, distributed systems of interacting agents are becoming ubiquitous. Such systems …

Finding the mean of the total number N tot of stationary points for N-dimensional random
energy landscapes is reduced to averaging the absolute value of the characteristic …

We study analytically a simple game theoretical model of heterogeneous interacting agents.
We show that the stationary state of the system is described by the ground state of a …

We present and study a Minority Game based model of a financial market where adaptive
agents—the speculators—interact with deterministic agents—called producers. Speculators …

We define and study a rather complex market model, inspired from the Santa Fe artificial
market and the Minority Game. Agents have different strategies among which they can …

New continuous and stochastic extensions of the minority game, devised as a fundamental
model for a market of competitive agents, are introduced and studied in the context of …

We address the question of market efficiency using the Minority Game (MG) model. First we
show that removing unrealistic features of the MG leads to models which reproduce a …

Experimental econophysics is concerned with statistical physics of humans in the laboratory,
and it is based on controlled human experiments developed by physicists to study some …
