|[+] Dictionaries: universal, k-wise independent, simple tabulation hashing; chaining, dynamic perfect hashing, linear probing, cuckoo hashing||Scribe Notes [src]|
|Today's lecture gives a fairly thorough overview of different approaches to hashing. First, we talk about different hash functions and their properties, from basic universality to k-wise independence, to a simple but effective hash function called simple tabulation. Then we talk about different approaches to using these hash functions in a data structure: basic chaining, (dynamic) perfect hashing, classic but tricky-to-analyze linear probing, and the more recent cuckoo hashing.|
