What is this? U assigning homework?
How about u lay out the parameters used(how many total nukes in exchange...what target cities...air burst vs ground burst...etc)
What was modelled?...wind speed/direction, the amount of debris thrown into atmosphere, amount of fall out, fuel density and fire intensity(would vary for each city), and so on.
I highly doubt u were able to run a simulation modelling all that on ur "super advanced" home computer that u r showing off about.
From ur back and forth...it seems like u have taken some number off the internet about Pakistan's number of nuclear weapons, their yield, Indian population, the amount of ppl killed by a certain yield nuclear bomb(like for example the known example from Hiroshima and Nagasaki) and then with some simple arithmetic...u arrived at a crude number of deaths for Indian side.
If it's something like that or similar enough...plz don't bother engaging me with such a "study"(if we can call it that).
