In computer science, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [2]
In computer science, tabulation hashing is a method for constructing universal families of hash functions by combining table lookup with exclusive or operations. It was first studied in the form of Zobrist hashing for computer games; later work by Carter and Wegman extended this method to arbitrary fixed-length keys. Generalizations of ...
Robert John Jenkins Junior (born 1966 [1] in Akron, Ohio), also known as Bob Jenkins, is an American computer professional and author of several fast pseudorandom number generators such as ISAAC [2] [3] [4] and hash functions (Jenkins hash) [5] [6]
ISAAC, the International Symposium on Algorithms and Computation, is an academic conference in the field of theoretical computer science. ISAAC has been organized annually since 1990. The proceedings are published by Springer-Verlag in the LNCS series. [1]
In computer science, SUHA (Simple Uniform Hashing Assumption) is a basic assumption that facilitates the mathematical analysis of hash tables.The assumption states that a hypothetical hashing function will evenly distribute items into the slots of a hash table.
In a hash table, a hash function takes a key as an input, which is associated with a datum or record and used to identify it to the data storage and retrieval application. The keys may be fixed-length, like an integer, or variable-length, like a name. In some cases, the key is the datum itself.
Linear probing is a component of open addressing schemes for using a hash table to solve the dictionary problem.In the dictionary problem, a data structure should maintain a collection of key–value pairs subject to operations that insert or delete pairs from the collection or that search for the value associated with a given key.
In computer science, lazy deletion refers to a method of deleting elements from a hash table that uses open addressing. In this method, deletions are done by marking an element as deleted, rather than erasing it entirely. Deleted locations are treated as empty when inserting and as occupied during a search.
