关于一般图中匹配取整的注记

A Note on Rounding Matchings in General Graphs

Aditi Dudeja

AI总结:

本文重新审视Wajc的取整算法,证明其适用于一般图,并展示其在加权分数匹配取整中的有用性质。

摘要:

在本文中,我们重新审视了Wajc的取整算法。Wajc给出了一种完全自适应的随机算法,该算法在无权重二分图中将动态分数匹配取整为几乎相同值的整数匹配,更新时间为$O(\text{poly}(\log n,\frac{1}{\varepsilon}))$。我们证明该算法的保证同样适用于一般图。此外,我们展示了该子程序的有用性质,这些性质在加权分数匹配的取整中具有应用价值。

英文摘要:

In this note, we revisit the rounding algorithm of Wajc. Wajc gave a fully-adaptive randomized algorithm that rounds a dynamic fractional matching in an unweighted bipartite graph to an integral matching of nearly the same value in $O(\text{poly}(\log n,\frac{1}{\varepsilon}))$ update time. We give show that the guarantees of this algorithm hold for general graphs as well. Additionally, we show useful properties of this subroutine which have applications in rounding weighted fractional matchings.
