Collective Intelligence for Control of Distributed Dynamical Systems. D. H. Wolpert, K. Wheeler, and K. Tumer. Europhysics Letters, 49(6), March 2000.

Abstract

We consider the El Farol bar problem (W. B. Arthur, The American Economic Review , 84(2): 406--411 (1994), D. Challet and Y.C. Zhang, Physica A , 256:514 (1998)) as an instance of the general problem of how to automatically configure a distributed dynamical system so that its nodal elements do not "work at cross purposes", in that their collective dynamical behavior successfully achieves a global goal. We present a summary of a mathematical theory for such automated configuration applicable when (as in the bar problem) the global goal can be expressed as minimizing a global energy function. We then investigate the applicability of the core concepts of that theory to a difficult variant of the bar problem. We show that a system designed in accord with that theory performs nearly optimally for the bar problem, and in particular avoids the tragedy of the commons for that problem.
