A sequence that would greatly surprise a user. For example, if you generate 32-bit ints from the Twister in one obvious way, there are starting places where you'll get 623 zeroes in a row. And places where you'll get 2**32-1 623 times in a row. Pick a sequence of any 623 32-bit ints, and there's a starting place that will deliver that sequence. And, indeed, a truly random sequence must also display that behavior, but it's nevertheless very surprising when you see one. It's very rare, both in a truly random sequence and in sequences derived from the Twister. |
