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...

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...

The generalization of the problem of adaptive competition, known as the minority game, to the case of K possible choices for each player, is addressed, and applied to a system of interacting perceptrons with input and output units of a type of K-state Potts spins. An optimal solution of this minority game, as well as the dynamic evolution of the adaptive strategies of the players, are solved an...

We discuss a recently introduced model of heterogeneous interacting agents behaving under inductive rationality. We derive the exact solution of the model in the limit of infinitely many agents using tools of statistical physics of disordered systems. Our results show that the impact of agents on the collective behavior plays a key role: even though for each agent this effect is very small, the...

The Israeli Plonit case concerns a Muslim woman who wished to be represented by a female arbitrator in a Shari’a Court. The Shari’a Court of Appeals denied her request and decided that Shari’a Law permits only men to serve as arbitrators. Plonit petitioned the Israeli Supreme Court, which accepted her petition and decided that the Shari’a Court of Appeals’ decision infringed her right to equali...

OBJECTIVES Language has been identified as a determinant of mental health. Within Canada, individuals may speak an official language and still belong within the linguistic minority (Francophones outside Quebec and Anglophones within Quebec). The objectives of this study were to compare mental health problems between minority and majority official language communities, and examine the associatio...

The aim of the study was to examine the social networks of sexual minority youths and to determine the associations between social networks and depressive symptoms. Data were obtained from the National Longitudinal Study of Adolescent Health (Add Health), a nationally representative cohort study of American adolescents (N = 14,212). Wave 1 (1994-1995) collected extensive information about the s...
