A. Condensed Matter Physics 1. Stochastic Strategies for Minority Games
نویسنده
چکیده
The Minority Game is a model of interacting agents, who try to choose between two options every day, and those who are in the minority are winners. In an earlier paper, efficient stochastic strategies for this game was analyzed when the number of agents is 3, 5, 7. When the number of agents is large, the behaviour is qualitatively different, and as the discount parameter is varied, there is a sudden transition from random choice to win-stay-lose-shift strategy.

We discuss several stochastic optimization strategies in games with many players having large number of choices (Kolkata Paise Restaurant Problem) and two choices (minority game problem). It is seen that a stochastic crowd avoiding strategy gives very efficient utilization in KPR problem. A slightly modified strategy in the minority game problem gives full utilization but the dynamics stops aft...
متن کاملGeneralized minority games with adaptive trend-followers and contrarians.
We introduce a simple extension of the minority game in which the market rewards contrarian (respectively, trend-following) strategies when it is far from (respectively, close to) efficiency. The model displays a smooth crossover from a regime where contrarians dominate to one where trend-followers dominate. In the intermediate phase, the stationary state is characterized by non-Gaussian featur...
متن کاملStochastic low Reynolds number swimmers.
As technological advances allow us to fabricate smaller autonomous self-propelled devices, it is clear that at some point directed propulsion could not come from pre-specified deterministic periodic deformation of the swimmer's body and we need to develop strategies for extracting a net directed motion from a series of random transitions in the conformation space of the swimmer. We present a th...

متن کاملMinority games with score-dependent and agent-dependent payoffs.
Score-dependent and agent-dependent payoffs of the strategies are introduced into the standard minority game. The intrinsic periodicity is consequently removed, and the stylized facts arise, such as long-range volatility correlations and "fat tails" in the distribution of the returns. The agent dependence of the payoffs is essential in producing the long-range volatility correlations. The new p...
