寻找无标度非齐次随机图的诱导子图

Finding induced subgraphs in scale-free inhomogeneous random graphs

Ellen Cardinaels, Johan S. H. van Leeuwaarden, Clara Stegehuis

摘要:

本文研究了幂律度为无穷大的非齐次随机图的导出子图的副本问题。我们提供了一个快速算法,找到一个副本的任何连接图$H$上的一个固定数量的$k$顶点作为诱导子图中的随机图与$n$顶点。通过利用无标度图结构,该算法运行在$O(n k)$时间为小值的$k$。作为推论,这表明对于非齐次随机图,导出子图同构问题可以在时间$O(nk)$中求解。我们在几个真实世界的数据集上测试我们的算法。

英文摘要:

We study the problem of finding a copy of a specific induced subgraph on inhomogeneous random graphs with infinite variance power-law degrees. We provide a fast algorithm that finds a copy of any connected graph $H$ on a fixed number of $k$ vertices as an induced subgraph in a random graph with $n$ vertices. By exploiting the scale-free graph structure, the algorithm runs in $O(n k)$ time for small values of $k$. As a corollary, this shows that the induced subgraph isomorphism problem can be solved in time $O(nk)$ for the inhomogeneous random graph. We test our algorithm on several real-world data sets.
