PPT-Backyard Cuckoo Hashing:

Constant WorstCase Operations with a Succinct Representation Yuriy Arbitman Moni Naor Gil Segev Dynamic Dictionary Data structure representing a set of words S From a Universe . harvardedu Abstract The purpose of this brief note is to describe recent work in the area of cuckoo hashing including a clear description of several open problems with the hope of spurring further research 1 Introduction Hashbased data structures and The analysis uses only very basic and intuitively understandable concepts of probability theory and is meant to be accessible even for undergraduates taking their 64257rst algorithms course 1 Introduction dictionary is a data structure for storing a Up to this point the greatest drawback of cuckoo hashing appears to be that there is a polynomially small but practically signicant probability that a failure occurs during the insertion of an item requiring an expensive rehashing of all items in th Practically Better Than Bloom.
