Go up one level in this thread


For 64 bit integers you can use the 'maximum haming distance' as a measure of
randomness.  This is the maximum number of bits any two number in the set have
in common e.g. 10101010 and 00001111 have 4 bits in common.  The higher the
maximum haming distance the less random (for the purposes of hashing etc).
