稠密图的容差二分性检验

Tolerant Bipartiteness Testing in Dense Graphs

Arijit Ghosh, Gopinath Mishra, Rahul Raychaudhury, Sayantan Sen

摘要:

自Goldreich、Goldwasser和Ron [FOCS'96和JACM'98]开创性工作以来,双边测试一直是属性测试领域的中心问题。虽然非宽容版本的二分测试已被广泛研究的文献中,宽容的变种是没有得到很好的理解。在本文中,我们考虑以下版本的宽容的二分测试:给定一个参数$\varepsilon \in (0,1)$和访问的邻接矩阵的图形$G$,我们可以决定是否$G$是$\varepsilon$ -接近被二分或$G$至少是$(2+Ω(1))\varepsilon$ -远离被二分,通过执行$\widetilde{\mathcal{O}}\left(\frac{1}{\varepsilon ^3}\right)$查询,并在$2^{\widetilde{\mathcal{O}}(1/\varepsilon)}$时间。这分别改进了来自Alon、Fernandez de la Vega、Kannan和Karpinski的工作(STOC'02和JCSS'03)的$\widetilde{\mathcal{O}}\left(\frac{1}{\varepsilon ^6}\right)$和$2^{\widetilde{\mathcal{O}}(1/\varepsilon^2)}$的该问题的最先进的查询和时间复杂度,其中$\widetilde{\mathcal{O}}(\cdot)$在$\log \frac{1}{\varepsilon}$中隐藏因子多项式。

英文摘要:

Bipartite testing has been a central problem in the area of property testing since its inception in the seminal work of Goldreich, Goldwasser and Ron [FOCS'96 and JACM'98]. Though the non-tolerant version of bipartite testing has been extensively studied in the literature, the tolerant variant is not well understood. In this paper, we consider the following version of tolerant bipartite testing: Given a parameter $\varepsilon \in (0,1)$ and access to the adjacency matrix of a graph $G$, we can decide whether $G$ is $\varepsilon$-close to being bipartite or $G$ is at least $(2+Ω(1))\varepsilon$-far from being bipartite, by performing $\widetilde{\mathcal{O}}\left(\frac{1}{\varepsilon ^3}\right)$ queries and in $2^{\widetilde{\mathcal{O}}(1/\varepsilon)}$ time. This improves upon the state-of-the-art query and time complexities of this problem of $\widetilde{\mathcal{O}}\left(\frac{1}{\varepsilon ^6}\right)$ and $2^{\widetilde{\mathcal{O}}(1/\varepsilon^2)}$, respectively, from the work of Alon, Fernandez de la Vega, Kannan and Karpinski (STOC'02 and JCSS'03), where $\widetilde{\mathcal{O}}(\cdot)$ hides a factor polynomial in $\log \frac{1}{\varepsilon}$.
