'Double hashing' diaporamas de présentation

Double hashing

Double hashing. Outline. This topic covers double hashing More complex than linear or quadratic probing Uses two hash functions The first gives the bin The second gives the jump size Primary clustering no longer occurs More efficient than linear or quadratic probing. Background.
