摘要

在本文中,我们证明对于任意阶为 mm 的图 HH 和任意阶为 nn 且最大度数为 Δ\Delta 的图 GG,可以计算 V(G)V(G) 的子集 SS 中诱导出与 HH 同构的图的数量,时间为 O(cmn)O(c^m\cdot n),其中某个常数 c=c(Δ)>0c = c(\Delta) > 0。这基本上是最优的。

备注

In this version we have improved the running time from $O(c^m\cdot n^2)$ to $O(c^m\cdot n)$. To incorporate this, we had to apply some minor changes, mostly in Section 2, leaving the overall approach essentially unaffected. 10 pages
