Cuckoo hashing - Wikipedia

WebTo apply this to (d-ary) cuckoo hashing, simply resize each of the subtables individually and don't move keys between subtables. To shrink the table, you need to confirm that one of { H mod L 2 + L 2, H mod L 2 } is vacant for every key in the table, and if so, move them all to their H mod L 2 slots. Of course, this is O ( n) ...

Cuckoo's Cafe Bubble Tea and Snacks! www.cuckooscafe.com Cuckoo hashing is a form of open addressing in which each non-empty cell of a hash table contains a key or key–value pair. A hash function is used to determine the location for each key, and its presence in the table (or the value associated with it) can be found by examining that cell of the table. However, open … See more Cuckoo hashing is a scheme in computer programming for resolving hash collisions of values of hash functions in a table, with worst-case constant lookup time.
