Minority game strategies in dynamic multi-agent role assignment

Tingting Wang, Jiming Liu, Xiaolong Jin
Proceedings. IEEE/WIC/ACM International Conference on Intelligent Agent Technology, 2004. (IAT 2004).  
In this paper, we propose a formulation of MG strategies in the role assignment problem in a particular multi-agent system: Simulation Robot Soccer.  ...  An attractive problem in team-based games is the role assignment problem.  ...  Conclusion In this paper, we described a challenging domain in multi-agent research, the role assignment problem and a recently emerged game theory, the Minority Game (MG).  ...

A Study On Multi-Agent Behavior In A Soccer Game Domain

S. R. Mohd Shukri, M. K. Mohd Shaukhi
2008 Zenodo  
One of the challenging issues in a soccer game is the cooperation, coordination and negotiation among distributed agents in a multi-agent system.  ...  This paper focuses on the incorporation of multi-agent technique in a soccer game domain. The better the cooperation of a multi-agent team, the more intelligent the game will be.  ...  Is role assignment more important than formation in a multi-agent behavior? Formation can only occurs when role assignment is determined for the entire agent in the team.  ...

Incorporating inertia into multiagent systems

W. C. Man, H. F. Chau
2006 Physical Review E  
We consider a model that demonstrates the crucial role of inertia and stickiness in multi-agent systems, based on the Minority Game (MG).  ...  The inertia of an agent is introduced into the game model by allowing agents to apply hypothesis testing when choosing their best strategies, thereby reducing their reactivity towards changes in the environment  ...  ACKNOWLEDGMENTS We thank the Computer Center of HKU for their helpful support in providing the use of the HPCPOWER system for simulations reported in this paper.

Evolution in minority games. (II). Games with variable strategy spaces

Yi Li, Rick Riolo, Robert Savit
2000 Physica A: Statistical Mechanics and its Applications  
We continue our study of evolution in minority games by examining games in which agents with poorly performing strategies can trade in their strategies for new ones from a different strategy space.  ...  We find, in all the games we study, that after evolution, wealth per agent is high for agents with strategies drawn from small strategy spaces (small m), and low for agents with strategies drawn from large  ...  z in the fixed m minority game: In the multi-m game, the system automatically picks out the value m t which plays the role of m c in these games.  ...

Anomalous fluctuations in Minority Games and related multi-agent models of financial markets [article]

Tobias Galla, Giancarlo Mosetti, Yi-Cheng Zhang
2006 arXiv   pre-print
One of the most prominent examples is here the Minority Game (MG), which we address in some more detail.  ...  We review the recent approaches to modelling financial markets based on multi-agent systems.  ...  It is straightforward to extend the model to majority game or mixed minority/majority games (in which some agents play an minority game, and others a majority game) [28, 24] .  ...

A Generic Multi-Robot Coordination Strateg Layer

João Certo, Nuno Lau, Luis P. Reis
2007 The Proceedings of First International Conference on Robot Communication and Coordination  
Managing a team of heterogeneous robots in a dynamic environment poses a challenging job. In this paper a model for a multi-purpose, real-time, adaptable, strategical coordination layer is presented.  ...  A multi-level hierarchical approach was followed with hybrid methods used to switch between concepts. The model was tested with two strategy instances, RoboCup Rescue Simulation and RoboCup Soccer.  ...  Next, the assignment of a specific agent to a specific role is discussed. In order to assign roles, each agent must be capable of differentiating himself from others.  ...

Calibrating emergent phenomena in stock markets with agent based models

Lucas Fievet, Didier Sornette, Fenghua Wen
2018 PLoS ONE  
Starting from the common definition of standard minority and majority agents with binary strategies, we prove their equivalence to optimal decision trees.  ...  Since the 2008 financial crisis, agent-based models (ABMs), which account for out-of-equilibrium dynamics, heterogeneous preferences, time horizons and strategies, have often been envisioned as the new  ...  In typical multi-agent simulations, some heterogeneity among agents is introduced by assigning to each agent A i a subset S % i S % of all possible strategies.  ...

Dynamical Mechanisms in Multi-agent Systems: Minority Games [article]

K. Y. Michael Wong, S. W. Lim, Zhuo Gao
2003 arXiv   pre-print
We consider a version of large population games whose agents compete for resources using strategies with adaptable preferences. Diversity among the agents reduces their maladpative behavior.  ...  When diversity increases, the scaling dynamics is modified by kinetic sampling and waiting mechanisms.  ...  The recently proposed Minority Games (MG) are prototypes of such multi-agent systems [2] .  ...

Limited resources and evolutionary learning may help to understand the mistimed reproduction in birds caused by climate change

Daniel Campos, Josep E. Llebot, Vicenç Méndez
2008 Theoretical Population Biology  
We present an agent-based model inspired by the Evolutionary Minority Game (EMG), albeit strongly adapted, to the case of competition for limited resources in ecology.  ...  The agents in this game become able, after some time, to predict the a priori best option as a result of an evolution-driven learning process.  ...  Minority games in ecology In general, minority games are helpful to describe multi-agent systems where each agent (individual) is able to analyze the history of the system (i.e., the success of the different  ...

Error-driven Global Transition in a Competitive Population on a Network [article]

Sehyo Charley Choe, Neil F. Johnson, Pak Ming Hui
2004 arXiv   pre-print
We show, both analytically and numerically, that erroneous data transmission generates a global transition within a competitive population playing the Minority Game on a network.  ...  This transition, which resembles a phase transition, is driven by a 'temporal symmetry breaking' in the global outcome series.  ...  In contrast to the agents' 'on-site' stochastic strategy selection arising in the Thermal Minority Game (TMG) [6, 9] , the stochasticity associated with q in our game depends on the agents' connectivity  ...
