I. Adjali et al., FLUCTUATIONS IN A DECENTRALIZED AGENT-RESOURCE SYSTEM, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 49(5), 1994, pp. 3833-3842
In this paper, a general formulation for a model of market-based agent
-resource systems is proposed, building on the computational ecosystem
model of Huberman and Hogg [in The Ecology of Computation, edited by
B. A. Huberman (North-Holland, Amsterdam, 1988)]. Our approach, based
on one-step Markov processes and Van Kampen's large-system-size expans
ion, allows the effects of fluctuations to be explored, particularly i
n finite systems where stochastic processes assume increasing importan
ce.
