布尔博弈系统中钉扎对资源分配效率的提升
Pinning improves resource allocation efficiency of boolean-game systems
资源分配在现实世界的复杂系统中以各种形式展现,比如交通系统(城市交通,航空系统,Internet网等),社会服务机构,乃至整个生态系统。这是系统中资源往往是有限的,个体基于获得的局部信息竞争利用率更低的资源,并且最终少数者获胜。在这类系统中,羊群行为对资源分配效率是有害的,但在真实情形下羊群行为却普遍存在,并表现为交通系统中的拥堵,金融系统中的大事件,或者表现为不同类型的社会危机,他们的共同特征是资源分配的低效率。为了阻止羊群行为、提高效率,本文给出固定(钉扎)某些个体选择的钉扎方案,并系统的研究了钉扎对布尔博弈系统的资源分配的影响。结果显示牺牲部分个体的选择权可能极大地提高整个系统的效率。在某些特殊情形,系统会通过自组织过程系统表现的比随机博弈系统更优越。本文同时建立了钉扎过程的解析理论,该理论基于离散时间主方程来描述钉扎效应。设计有效地钉扎方案同样有所讨论。这篇工作提供了一个基本并且普遍的数学框架来研究社会、生态等系统中的资源分配钉扎及涨落问题。
Resource allocation takes place in various kinds of real-worldcomplex systems, such as the traffic systems (e.g., urban trafficsystem and flight systems), social services institutions ororganizations (e.g., bank, theater, and mart, financial market),or even the ecosystems. Resources are always limited, and agentstend to choose the least used resource based on certain availableinformation, obeying the fundamental principle that theemph{minority wins}. In these systems, herd behavior is harmfulfor the efficiency of resource allocation. However, it isubiquitous in real cases, and present to be congestion in trafficsystem, extreme events in financial system, and other crisis insocial system, all of which are commonly characterized by the lowefficiency of resource allocation. For the sake of preventing herdbehavior and improving the efficiency,it is proposed thatpinning scheme to fix certain individuals' options, and itsystematically is studied that the effect of emph{pinning} to the resourceallocation dynamics of boolean game systems. The work demonstratesthat, the sacrifice of certain individuals' options may markedlyimprove the efficiency of the whole system. Especially, in certaincases, the system performs better than the random game systemthrough self-organized processes. We develop an analytic theorybased on the discrete time master equation to understand theeffect of pinning. The rule to design effective pinning scheme arealso discussed. The work represents a basic and generalmathematical framework to address the fluctuation of the resourceallocation in social, economical and political systems.
