不完善的最佳反应机制

Imperfect best-response mechanisms

Diodato Ferraioli, Paolo Penna

摘要:

最佳响应机制(Nisan,Schapira,Valiant,Zohar,2011)为研究各种分布式协议提供了一个统一的框架,其中参与者被指示反复对彼此的策略做出最佳响应。这些机制的两个基本特征是趋同和激励相容。这项工作研究的收敛性和激励相容性条件下,这种机制时,球员不能保证总是最好的反应,但他们发挥不完美的最佳对策。也就是说,在每一个时间步,每个参与者都根据某个概率参数偏离规定的最佳对策策略。结果解释了收敛和激励相容性在多大程度上取决于玩家从不犯错的假设,以及这些协议对“噪音”或“错误”的鲁棒性。

英文摘要:

Best-response mechanisms (Nisan, Schapira, Valiant, Zohar, 2011) provide a unifying framework for studying various distributed protocols in which the participants are instructed to repeatedly best respond to each others' strategies. Two fundamental features of these mechanisms are convergence and incentive compatibility. This work investigates convergence and incentive compatibility conditions of such mechanisms when players are not guaranteed to always best respond but they rather play an imperfect best-response strategy. That is, at every time step every player deviates from the prescribed best-response strategy according to some probability parameter. The results explain to what extent convergence and incentive compatibility depend on the assumption that players never make mistakes, and how robust such protocols are to "noise" or "mistakes".
