Cuckoo hashing example
WebMay 31, 2015 · A simple, hopefully illustrative example, is to suppose you've got some normal hash function you like, that operates on blocks of bytes. We'll call it H (x). You want to use it to produce a family of new, slightly different hash functions H_n (x). WebOver the years, many different hashing techniques have been proposed and studied in the literature, each with its own set of advantages and limitations. Some of the commonly used hashing techniques include static and dynamic hashing, perfect hashing, cuckoo hashing, bloom filters, and locality-sensitive hashing.

How the Cuckoo Hashing Works In cuckoo hashing, we maintain two hash position (and hash functions) h1 and h2. So if we need to store a key x, we would compute one of two postions h1 (x) and h2 …
WebCuckoo Hashing Library with variable hash functions and buckets I'm looking for an implementation of Cuckoo Hashing that allows to specify the number of hash functions (x) and the number of buckets per cell (y) . My goal is to experiment the load factor for each variation of (x, y) and put in a table to convey the finding.
