Evolving Populations of Agents with Personalities in the Minority Game

Wayward Agents in a Commuting Scenario

In our daily lives we often have to face binary decisions where we seek to take the minority’s choice, e.g., in traffic scenarios where we have to choose between similar alternative routes. We have studied agent coordination mechanisms in a binary decision model introduced in the literature recently: the Minority Game. Extending this model, we have introduced personalities which model certain t...

Environmental and Ecological Extra Challenges in Minority Populations; a Tale of Toxic Exposures among First Nation Populations

Effects of contrarians in the minority game.

We study the effects of the presence of contrarians in an agent-based model of competing populations. Contrarians are common in societies. These contrarians are agents who deliberately prefer to hold an opinion that is contrary to the prevailing idea of the commons or normal agents. Contrarians are introduced within the context of the minority game (MG), which is a binary model for an evolving ...

Heterogeneous Populations of Learning Agents in the Minority Game

We study how a group of adaptive agents can coordinate when competing for limited resources. A popular game theoretic model for this is the Minority Game. In this article we show that the coordination among learning agents can improve when agents use different learning parameters or even evolve their learning parameters. Better coordination leads to less resources being wasted and agents achiev...

Self-segregation versus clustering in the evolutionary minority game.

Complex adaptive systems have been the subject of much recent attention. It is by now well established that members ("agents") tend to self-segregate into opposing groups characterized by extreme behavior. However, the study of such adaptive systems has mostly been restricted to simple situations in which the prize-to-fine ratio R equals unity. In this Letter we explore the dynamics of evolving...
