Simplistic pseudo random number generators

Webb5 feb. 2014 · Pseudo-random number generators do essentially the same thing - they generate predictable numbers with the correct distribution. They are bad for the same reason that the simplistic random number generator above is bad - they are not suitable for situations where you need genuine unpredictability, not just the correct distribution.
