Quadratic Probing Revisited: Smoothed Analysis and the Fall of Robin Hood
Yang Hu, William Kuszmaul, Jingxun Liang +3
The paper studies a smoothed version of quadratic probing for hash tables, comparing Robin Hood and anti‑Robin Hood insertion orders and showing that anti‑Robin Hood achieves logar…
Adversarial Robustness for Small Frequency Moments and a Weak Equivalence Theorem for Turnstile Streams
Elena Gribelyuk, Honghao Lin, David P. Woodruff +2
We study adversarially robust algorithms for insertion-deletion (turnstile) streams, where future updates may depend on past algorithm outputs. While recent work achieved a robust…
Adversarial Robustness on Insertion-Deletion Streams
Elena Gribelyuk, Honghao Lin, David P. Woodruff +2
We study adversarially robust algorithms for insertion-deletion (turnstile) streams, where future updates may depend on past algorithm outputs. While robust algorithms exist for in…
Static Retrieval Revisited: To Optimality and Beyond
Yang Hu, William Kuszmaul, Jingxun Liang +3
In the static retrieval problem, a data structure must answer retrieval queries mapping a set of keys in a universe to -bit values. Information-theoretically, retrieva…
Optimal Static Dictionary with Worst-Case Constant Query Time
Yang Hu, Jingxun Liang, Huacheng Yu +2
In this paper, we design a new succinct static dictionary with worst-case constant query time. A dictionary data structure stores a set of key-value pairs with distinct keys in $[U…
