I see you've borrowed somebodies backpedalling bicycle.
Actually, in this context the difference between chaotic and stochastic is
one of degree. Both -require- the use of a RNG in at least one variable in
the system equations.
They are equivalent from this perspetive of analysis.
I'll go hog wild and give you another freebie I bet you don't have.
All RNG's are 'irrational generators' in that the sequence of numbers that
they generate must be irrational (ie don't repeat infinity-distribution
wise).
