给定度序列的二部图的随机均匀抽样

Towards random uniform sampling of bipartite graphs with given degree sequence

Péter L. Erdös, Istán Miklós, Lajos Soukup

摘要:

本文考虑了$n$顶点上具有给定度序列的二部图的简单马尔可夫链。证明了在{ \em semi-regular}度序列的情况下,该马尔可夫链的混合时间在$n$中的多项式上有界.我们的方法的新颖性在于Sinclair方法中的典型路径的构造。

英文摘要:

In this paper we consider a simple Markov chain for bipartite graphs with given degree sequence on $n$ vertices. We show that the mixing time of this Markov chain is bounded above by a polynomial in $n$ in case of {\em semi-regular} degree sequence. The novelty of our approach lays in the construction of the canonical paths in Sinclair's method.
