I doubt it very much, in a case, of course, some good pseudo
random number generator is used. The problem is it can have
large number of possible states, and there is no simple rule
telling next value from one or few previous.
Go to my page http://www.fuw.edu.pl/~jt/, choose "zfja-gate",
then "rand/", and load "jt-rand.zip". It contains pseudo-random
number generator I wrote few years ago. It has period 2^120.
So, happy guessing of its state - it can take more than age of
the Universe onless one find a way to derive it from values.
(and, it it rather quick - maybe it would be good idea to put
it on Linux as device and use when need pseudo-randon numbers?)
