uniform hashing

(algorithm)

Definition: A conceptual method of open addressing for a hash table. A collision is resolved by putting the item in the next empty place given by a probe sequence which is independent of sequences for all other key.

See also collision resolution scheme, clustering free, double hashing, quadratic probing, linear probing, perfect hashing, simple uniform hashing.

Note: Since the probe sequences are independent, this is free of clustering. This is conceptual because real probe sequences are unlikely to be completely independent.
