A perfect hash function maps a static set of n keys into a set of m integer
|
|
numbers without collisions, where m is greater than or equal to n. If m is
|
|
equal to n, the function is called minimal.
|
|
|
|
Minimal perfect hash functions are widely used for memory efficient storage
|
|
and fast retrieval of items from static sets, such as words in natural
|
|
languages, reserved words in programming languages or interactive systems,
|
|
universal resource locations (URLs) in Web search engines, or item sets in
|
|
data mining techniques. Therefore, there are applications for minimal
|
|
perfect hash functions in information retrieval systems, database systems,
|
|
language translation systems, electronic commerce systems, compilers,
|
|
operating systems, among others.
