Congestion, equilibrium and learning: The minority game∗

The minority game is a simple congestion game with two actions and an odd number of players. Players want to choose the action that is chosen by the minority of players. We characterize the set of equilibria of the game. As the set of equilibria is large, a natural question is which equilibrium will be selected by the players. Since the pure Nash equilibria of the game are not strict and lead t...

I propose the coefficient, t h , and its modification Nt which in a simple way reflect dynamics of scientific activity of an individual researcher. I determine t h as a time period (from some moment in the past till the present moment) during which papers responsible for 1/2 of the total citation index were published. Parameter Nt represents average of the citation index over this period: Nt = ...

The efficiency of a large hierarchical organisation is simulated on Barabási-Albert networks, when each needed link leads to a loss of information. The optimum is found at a finite network size, corresponding to about five hierarchical layers, provided a cost for building the network is included in our optimization.

The minority game: An economics perspective

This paper gives a critical account of the minority game literature. The minority game is a simple congestion game: players need to choose between two options, and those who have selected the option chosen by the minority win. The learning model proposed in this literature seems to differ markedly from the learning models commonly used in economics. We relate the learning model from the minorit...
