摘要:

$k$维Weisfeiler-Leman算法($k$ -WL)是一种非常有用的图同构测试组合工具。我们解决的适用性$k$ -WL识别的图形属性。设$G$是具有$n$顶点的输入图。我们表明,如果$n$是素数,那么$G$的顶点传递性可以从$G$和$G$的顶点个体化副本上的2-WL的输出中以直接的方式看出。然而,如果$n$可被16整除,则$k$不能区分具有$n$顶点的顶点传递图和非顶点传递图,只要$k=o(\sqrt n)$。对于弧传递性的识别也得到了类似的结果。

英文摘要:

The $k$-dimensional Weisfeiler-Leman algorithm ($k$-WL) is a very useful combinatorial tool in graph isomorphism testing. We address the applicability of $k$-WL to recognition of graph properties. Let $G$ be an input graph with $n$ vertices. We show that, if $n$ is prime, then vertex-transitivity of $G$ can be seen in a straightforward way from the output of 2-WL on $G$ and on the vertex-individualized copies of $G$. However, if $n$ is divisible by 16, then $k$-WL is unable to distinguish between vertex-transitive and non-vertex-transitive graphs with $n$ vertices as long as $k=o(\sqrt n)$. Similar results are obtained for recognition of arc-transitivity.
