  2. Linear probing - Wikipedia

    en.wikipedia.org/wiki/Linear_probing

    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.

  3. Open addressing - Wikipedia

    en.wikipedia.org/wiki/Open_addressing

    Hash collision resolved by linear probing (interval=1). Open addressing, or closed hashing, is a method of collision resolution in hash tables.With this method a hash collision is resolved by probing, or searching through alternative locations in the array (the probe sequence) until either the target record is found, or an unused array slot is found, which indicates that there is no such key ...

  4. Primary clustering - Wikipedia

    en.wikipedia.org/wiki/Primary_clustering

    In computer programming, primary clustering is a phenomenon that causes performance degradation in linear-probing hash tables.The phenomenon states that, as elements are added to a linear probing hash table, they have a tendency to cluster together into long runs (i.e., long contiguous regions of the hash table that contain no free slots).

  5. Hash table - Wikipedia

    en.wikipedia.org/wiki/Hash_table

    Linear probing performs better due to better locality of reference, though as the table gets full, its performance degrades drastically. Open addressing is another collision resolution technique in which every entry record is stored in the bucket array itself, and the hash resolution is performed through probing.

  6. Hash function - Wikipedia

    en.wikipedia.org/wiki/Hash_function

    In open address hashing, the table is probed starting from the occupied slot in a specified manner, usually by linear probing, quadratic probing, or double hashing until an open slot is located or the entire table is probed (overflow). Searching for the item follows the same procedure until the item is located, an open slot is found, or the ...

  7. Cuckoo hashing - Wikipedia

    en.wikipedia.org/wiki/Cuckoo_hashing

    In practice, cuckoo hashing is about 20–30% slower than linear probing, which is the fastest of the common approaches. [1] The reason is that cuckoo hashing often causes two cache misses per search, to check the two locations where a key might be stored, while linear probing usually causes only one cache miss per search.

    His short reply was taken as a sign of weak faith, and it was proposed that as punishment he write 1,000 words on the theme “Only God can judge me,” attend the rehab’s beginner classes on the Big Book again, and complete close to a dozen other writing assignments aimed at probing the depths of his beliefs and his self-esteem.

  9. Associative array - Wikipedia

    en.wikipedia.org/wiki/Associative_array

    Linear probing performs better due to better locality of reference, though as the table gets full, its performance degrades drastically. The most frequently used general-purpose implementation of an associative array is with a hash table : an array combined with a hash function that separates each key into a separate "bucket" of the array.
