Abstract

This paper explores the increasing the heterogeneity of an agent population to stabilize decentralized systems by adding bias terms to each agent's expected payoffs. Two approaches are evaluated, corresponding to heterogeneous preferences and heterogeneous transaction costs; empirically, the transaction cost case provides stability with near optimal payoffs under certain conditions. Theoretically, in the idealized case of an infinite number of agents, it is proven that the system with added heterogeneous preferences has a fired point different from that of the unbiased system, guaranteeing suboptimal perfomance, while the transaction cast case is demonstrated to have a fixed point identical to that of the unbiased system, and it is further shown to be a contraction mapping, guaranteeing convergence. This contraction mapping allows us to conceptualize the model with heterogeneous transaction costs as a decentralized root finding system.
分布式系统的异构性、稳定性和效率
本文探讨了通过在每个agent的预期收益中添加偏差项来增加agent群体的异质性以稳定分散系统。评估了两种方法,对应于异质性偏好和异质性交易成本;经验表明,交易成本情况在一定条件下提供了接近最优收益的稳定性。从理论上证明了在无穷多个智能体的理想情况下,加入异构偏好的系统有一个与无偏系统不同的起始点,保证了次优性能;而事务投射的情况下,有一个与无偏系统相同的不动点,并进一步证明了它是一个收缩映射,保证了收敛性。这种收缩映射允许我们将具有异构交易成本的模型概念化为分散的寻根系统。
