<DIV>it's nice to observe that an extensive/productive conversation has come about </DIV>
<DIV>from my question in regards to "random" systems, and it's quite </DIV>
<DIV>informative to follow, and frankly a bit far from my current reach</DIV>
<DIV>of knowledge, but what is important for me at the moment </DIV>
<DIV>is to learn the general difference between random & pseudo-random & the various </DIV>
<DIV>applications that is possible with random systems via the several examples given.</DIV>
<DIV>will try to build from there...</DIV>
<DIV> </DIV>
<DIV>thanks again folks, :)</DIV>

Sometimes you may want a repeating chaotic sequence, sometimes a completely random one.<BR><BR>For cryptography, as in a one-time pad, pseudo-random is relatively easy to crack. There are at most 65536 different sequences with typical pseudo-random generators, but that's not any inherent limitation of pseudo-random, just the particular implementation that's often used.<BR><BR>Also with games like rolling dice or shuffling cards, you probably want it to be completely unpredictable, or regular players will begin to recognize patterns.<BR><BR>Pseudo-random white noise playing at audio rate will actually be a repeating waveform several minutes or hours long. It's up to you if that matters or
not.<BR><BR>Martin<BR></DIV></DIV></div><br>
