Hamilton圈个数的上界

Upper Bounds for the Number of Hamiltonian Cycles

Jinshan Zhang

摘要:

本文首先建立了对称有向图的Hamilton圈数的一个上界,它比著名的Minc界和Br $\acute{e}$ gman界更严格.提出了一种图的变换,使得计算无向图的Hamilton圈数可以通过计算其对应的对称有向图的Hamilton圈数来实现.这样,也得到了无向图的Hamilton圈数的一个上界。

英文摘要:

An upper bound for the number of Hamiltonian cycles of symmetric diagraphs is established first in this paper, which is tighter than the famous Minc's bound and the Br$\acute{e}$gman's bound. A transformation on graphs is proposed, so that counting the number of Hamiltonian cycles of an undirected graph can be done by counting the number of Hamiltonian cycles of its corresponding symmetric directed graph. In this way, an upper bound for the number of Hamiltonian cycles of undirected graphs is also obtained.
