Re: random??



Sir
    Really appreciate your help, but I have a question about that I didn't
find any explain in NS-Note & Docu then where can I find that description
about that ns-random. In my simualtion I have no random variables so I have no
way to attach rng on it.  I don't know what the RNG is made up while start up,
is it deterministic or heuristic?
thanks your help

regards
Robert
