TLDR
A data structure for representing a set of n items from a universe of m items, which uses space n+o(n) and accommodates membership queries in constant time and is easy to implement.
Abstract
A data structure for representing a set of n items from a umverse of m items, which uses space n + o(n) and accommodates membership queries m constant time is described. Both the data structure and the query algorithm are easy to ~mplement.

On low dimensional models for functions in high dimensions

Hemant Tyagi
TL;DR: A simple algorithm is derived that achieves nearly optimal regret bounds, with the rate depending only on k and not d, and is extended to the scenario where the subset of active coordinate variables can possibly change across time.

Space optimal packet classification for 2D conflict-free filters

TL;DR: A linear space data structure with O(min{logiu loglogn, /spl radic/lognloglogn}) query time is designed for the 2D packet classification problem for a set of conflict-free filters in an IP network, which is the first optimal spaceData structure with poly-logarithmic query time for this problem.

Extended expedited forwarding: the in-time PHB group

TL;DR: This paper presents a new set of forwarding behaviors that fits rate-adaptive and delay-sensitive applications with limited loss tolerance, and defines a scheduling mechanism that can be implemented efficiently and supports the defined forwarding behaviors.

Should Tables Be Sorted

TL;DR: It is shown that, in a rather general model including al1 the commonly-used schemes, $\lceil $ lg(n+l) $\rceil$ probes to the table are needed in the worst case, provided the key space is sufficiently large.

Storing a sparse table

TL;DR: This work proposes a good worst-case method for storing a static table of n entries, each an integer between 0 and N - 1, and analysis shows why a simpler algorithm used for compressing LR parsing tables works so well.

Perfect hashing functions: a single probe retrieving method for static sets

TL;DR: A refinement of hashing which allows retrieval of an item in a static table with a single probe is considered, and a rough comparison with ordinary hashing is given which shows that this method can be used conveniently in several practical applications.

Reciprocal hashing: a method for generating minimal perfect hashing functions

TL;DR: A method is presented for building minimal perfect hash functions, i.e., functions which allow single probe retrieval from minimally sized tables of identifier sets, and a proof of existence for minimalperfect hash functions of a special type (reciprocal type) is given.
