WebSimilar to the PJW Hash function, but tweaked for 32-bit processors. Its the hash function widely used on most UNIX systems. * BKDR Hash Function. This hash function comes from Brian Kernighan and Dennis Ritchie's book "The C Programming Language". It is a simple hash function using a strange set of possible seeds which all constitute a pattern ... http://www.partow.net/programming/hashfunctions/ WebMurmurHash3. MurmurHash is a non-cryptographic hash function suitable for general hash-based lookup.It was created by Austin Appleby in 2008.It comes in 3 variants - a 32-bit version that targets low latency for hash table use and two 128-bit versions for generating unique identifiers for large blocks of data, one each for x86 and x64 platforms. easytickets web
