The Minority Game with interactions

TL;DR

This paper investigates how introducing local information for some agents in the Minority Game affects resource utilization, showing improvements at low interaction levels but deterioration at higher levels.

Contribution

It presents a modified Minority Game incorporating local interactions, revealing how varying interaction levels influence system efficiency.

Findings

Resource use improves with low interaction levels

System performance worsens as the fraction of interacting agents increases

Behavior transitions from improved to degraded compared to the standard MG

Abstract

We partially modify the rules of the Minority Game (MG) by introducing some degree of local information in the game, which is only available for some agents, called the interacting agents. Our work shows that, for small values of the new parameter of the model (the fraction of interacting agents), there is an improvement of the use of the resources with respect to the MG, while as this number grows the response of the system changes, and ends up behaving worst than the usual MG.
