Evolutionary minority games with small-world interactions
In the Evolutionary Minority Game (EMG), agents compete for a limited resource and are rewarded if they correctly select the minority behaviour. At each time step, agents make their decision based on the aggregate history of past moves and an internal parameter — the probability that the individual follows the given strategy. In this study, the effects of strategic imitation among agents are ex...
متن کاملEvolutionary Minority Games: the benefits of imitation
In the original Evolutionary Minority Game, a segregation into two populations with opposing preferences is observed under many circumstances. We show that this segregation becomes more pronounced and more robust if the dynamics are changed slightly, such that strategies with aboveaverage fitness become more frequent. Similar effects occur also for a generalization of the EMG to more than two c...
متن کاملStylized facts in minority games with memory: a new challenge
A finite memory is introduced in the score dynamics of Minority Games. As expected, this removes the dependence of the stationary state on the initial conditions. However, it also causes an unexpected increase of fluctuations in grand-canonical models for very large times. Current analytical methods are inadequate to solve this simple and natural extension.

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...
