Dynamics of multi-frequency minority games
The dynamics of minority games with agents trading on different time scales is studied via dynamical mean-field theory. We analyze the case where the agents’ decision-making process is deterministic and its stochastic generalization with finite heterogeneous learning rates. In each case, we characterize the macroscopic properties of the steady states resulting from different frequency and learn...

متن کاملCrowd-Anticrowd Theory of Multi-Agent Minority Games
We present a formal treatment of the Crowd-Anticrowd theory of Minority Games played by a population of competing agents. This theory is built around a description of the crowding which arises within the game’s strategy space. Earlier works have shown that this theory provides a simple, yet quantitatively accurate explanation of the time-averaged behavior of these multi-agent games. We also dis...
متن کاملHierarchically Organized Minority Games
In this paper a simple, single-level strategic game, namely the Minority Game (MG), will be extended to form a hierarchical organization. The individual MGs will form a group, and individual players within each MG will make decisions which depend on the average behavior of their own and other MGs. Calculations show that under certain conditions the elements of the individual MGs “know” much mor...
متن کاملColored minority games
The Minority Game (MG) [1] provides an ideal playground for studying interacting agent systems such as financial markets [2]. Its stationary states have indeed been understood in great detail [3–5] whose conclusions have been recently confirmed by a fully dynamic theoretical approach [6]. Such a state of the art allows one to address interesting issues on the way in which such complex systems b...
