论文摘要
我们提供了一个简单的证明,即该行的任何随机在线匹配算法的竞争比至少为$ \ sqrt {\ log_2(n \!+\!1)}/12 $,全部$ n = 2^i \! - \! - \!1:i \ in \ mathbb {n} $。
We present a simple proof that the competitive ratio of any randomized online matching algorithm for the line is at least $\sqrt{\log_2(n\!+\!1)}/12$ for all $n=2^i\!-\!1: i\in\mathbb{N}$.
