$c$ -闭图中小导出子图的检测与计数

Detecting and Enumerating Small Induced Subgraphs in $c$-Closed Graphs

Tomohiro Koana, André Nichterlein

摘要:

Fox等人[SIAM J. Comp. 2020]引入了一个新参数,称为$c$ -闭包,用于团枚举问题的参数化研究。一个图$G$是$c$ -闭的,如果至少有$c$公共邻居的每对顶点是相邻的. $G$的$c$ -闭包是最小的$c$,使得$G$是$c$ -闭包。我们系统地探讨了$c$ -闭包对检测和枚举小诱导子图的计算复杂性的影响。更确切地说,对于每个图$H$上的三个或四个顶点,我们调查参数多项式时间算法检测$H$和枚举所有出现的$H$在一个给定的$c$ -封闭图。

英文摘要:

Fox et al. [SIAM J. Comp. 2020] introduced a new parameter, called $c$-closure, for a parameterized study of clique enumeration problems. A graph $G$ is $c$-closed if every pair of vertices with at least $c$ common neighbors is adjacent. The $c$-closure of $G$ is the smallest $c$ such that $G$ is $c$-closed. We systematically explore the impact of $c$-closure on the computational complexity of detecting and enumerating small induced subgraphs. More precisely, for each graph $H$ on three or four vertices, we investigate parameterized polynomial-time algorithms for detecting $H$ and for enumerating all occurrences of $H$ in a given $c$-closed graph.
