AI总结:
本文提出一种次线性时间算法估计最大独立集大小,将运行时间从$\ ilde{O}(n^{1+1/2})$改进至$\ ilde{O}(n^{1+1/3})$,并由此改进次线性度量斯坦纳森林,同时将$k$-中心双准则估计归约到该问题。
AI中文摘要:
我们给出一个次线性时间算法,用于估计图中最大独立集的大小,该算法使用邻接查询访问,期望运行时间为$\ ilde{O}(n^{1+1/3})$,改进了Mahadabi等人[MRTV26]之前的$\ ilde{O}(n^{1+1/2})$界限。作为[MRTV26]中归约的结果,这也改进了次线性度量斯坦纳森林的运行时间。我们进一步表明,在一般度量中,$k$-中心目标的双准则估计可以通过归约到最大独立集大小估计来获得。
英文摘要:
We give a sublinear-time algorithm for estimating the size of a maximal independent set in a graph using adjacency-query access with expected running time $\tilde{O}(n^{1+1/3})$, improving over the previous $\tilde{O}(n^{1+1/2})$ bound of Mahadabi et al. [MRTV26]. As a consequence of a reduction of [MRTV26], this also improves the running time for sublinear metric Steiner forest. We further show that a bi-criteria estimate of the $k$-center objective in general metrics can be obtained via a reduction to maximal independent set size estimation.
