拟阵次小闭类的非自适应先知不等式

Non-Adaptive Prophet Inequalities for Minor-Closed Classes of Matroids

Kanstantsin Pashkovich, Alice Sayutina

AI总结:

针对拟阵先知不等式中非自适应机制的常数竞争保证问题,本文证明多个已知拟阵类别(次小闭类)均存在常数竞争的非自适应机制。

摘要:

我们研究拟阵先知不等式问题。该问题在自适应机制情形下已被广泛研究,特别是,针对所有拟阵存在一种紧的2-竞争机制。然而,尚不清楚哪些拟阵类别允许具有常数保证的非自适应机制。最近已有研究表明,图拟阵存在常数竞争的非自适应机制。在本工作中,我们证明多个已知拟阵类别均允许常数竞争的非自适应机制。

英文摘要:

We consider the matroid prophet inequality problem. This problem has been extensively studied in the case of adaptive mechanisms. In particular, there is a tight $2$-competitive mechanism for all matroids. However, it is not known what classes of matroids admit non-adaptive mechanisms with constant guarantee. Recently, it was shown that there are constant-competitive non-adaptive mechanisms for graphic matroids. In this work, we show that various known classes of matroids admit constant-competitive non-adaptive mechanisms.
