The minority game: effects of strategy correlations and timing of adaptation
PHYSICA A 324:1-2 (2003) 25-29
Abstract:
A brief review is given of the minority game, an idealized model of a market of speculative agents, and its complex many-body behaviour. Particular consideration is given to the consequences and implications of correlations between strategies and different frequencies and timings of adaptation. (C) 2003 Elsevier Science B.V.

Abstract:
We report on a study of the shape of a stiff, charged rod that is subjected to equal and opposite force couples at its two ends. Unlike a neutral elastic rod, which forms a constant curvature configuration under such influences, the charged rod tends to flatten in the interior and accumulate the curvature in the end points, to maximally reduce the electrostatic self-repulsion. The effect of this nonuniform bending on the effective elasticity and on the statistical conformations of a fluctuating charged rod is discussed. An alternative definition for the electrostatic persistence length is suggested. This definition is found to be consistent with a corresponding length that can be deduced from the end-to-end distribution function of a fluctuating polyelectrolyte.Thermodynamic perturbation theory of the phase behaviour of colloid / interacting polymer mixtures
