Twenty-Two New Approximate Proof Labeling Schemes (Full Version)
摘要:
\emph{proof labeling scheme (PLS)}是由Korman、Kutten和Peleg(分布式计算2005)介绍的一种系统,专门用于验证给定的配置图是否满足某个属性。它是由一个集中的\emph{prover},其作用是生成一个证明是的实例的形式的标签分配到节点,和一个分布式的\emph{verifier},其作用是验证的有效性证明本地的手段,并接受它,当且仅当该属性得到满足。为了克服某些图属性的PLS标签大小的下限,Censor-Hillel,Paz和Perry(SIROCCO 2017)引入了\emph{approximate proof labeling scheme (APLS)}的概念,允许验证者也接受一些无实例,只要它们距离满足属性“太远”。
英文摘要:
Introduced by Korman, Kutten, and Peleg (Distributed Computing 2005), a \emph{proof labeling scheme (PLS)} is a system dedicated to verifying that a given configuration graph satisfies a certain property. It is composed of a centralized \emph{prover}, whose role is to generate a proof for yes-instances in the form of an assignment of labels to the nodes, and a distributed \emph{verifier}, whose role is to verify the validity of the proof by local means and accept it if and only if the property is satisfied. To overcome lower bounds on the label size of PLSs for certain graph properties, Censor-Hillel, Paz, and Perry (SIROCCO 2017) introduced the notion of an \emph{approximate proof labeling scheme (APLS)} that allows the verifier to accept also some no-instances as long as they are not "too far" from satisfying the property.
