本科生发现了一种新型哈希表颠覆了姚期智 40 年前的猜想
lavvrence · 2025-02-11 · via V2EX

Quote:

for this new hash table, the time required for worst-case queries and insertions is proportional to (log x)^2 — far faster than x

即便是满载(负载因子 100%)的一张哈希表,最差也能实现(log x)^2 时间复杂度的查询,比姚期智提出的理论下限 x 要快很多,(不依赖 hash 表内的负载程度)。基于 Tiny Pointers 实现。

这是不是意味着很多编程语言内置的哈希表实现将被重写?
