* DJBX33A (Daniel J. Bernstein, Times 33 with Addition)
|
|
*
|
|
* This is Daniel J. Bernstein's popular `times 33' hash function as
|
|
* posted by him years ago on comp.lang.c. It basically uses a function
|
|
* like ``hash(i) = hash(i-1) * 33 + str[i]''. This is one of the best
|
|
* known hash functions for strings. Because it is both computed very
|
|
* fast and distributes very well.
|
|
*
|
|
* The magic of number 33, i.e. why it works better than many other
|
|
* constants, prime or not, has never been adequately explained by
|
|
* anyone. So I try an explanation: if one experimentally tests all
|
|
* multipliers between 1 and 256 (as RSE did now) one detects that even
|
|
* numbers are not usable at all. The remaining 128 odd numbers
|
|
* (except for the number 1) work more or less all equally well. They
|
|
* all distribute in an acceptable way and this way fill a hash table
|
|
* with an average percent of approx. 86%.
|
|
*
|
|
* If one compares the Chi^2 values of the variants, the number 33 not
|
|
* even has the best value. But the number 33 and a few other equally
|
|
* good numbers like 17, 31, 63, 127 and 129 have nevertheless a great
|
|
* advantage to the remaining numbers in the large set of possible
|
|
* multipliers: their multiply operation can be replaced by a faster
|
|
* operation based on just one shift plus either a single addition
|
|
* or subtraction operation. And because a hash function has to both
|
|
* distribute good _and_ has to be very fast to compute, those few
|
|
* numbers should be preferred and seems to be the reason why Daniel J.
|
|
* Bernstein also preferred it.
