Enter integer positive numbers as seeds This is a deterministic noise generator, what this means is that the outcome depends entirely on the input (the seed) and if you put the same seed you will always get the same outcome which is predictable, because it's found through a process that is always the same. This doesn't seem to be affected by chaos, which means that a slight variation in the input doesn't change by much the outcome, making it predictable.
