us & Rob Cambell --> it was a mistake on my part to have omitted that specific file while uploading

Rob: The point is quite simple, clock time is 'predictable' however the change-in-world-population-count is not predictable.

To generate "near-pure" random numbers, it is necessary for the system to have an interface/input from the physical real world. In this scenario, the physical real world is the growth in human population, the interface is the count in human population numbers.

Beautiful! :-)
I was cracking my head converting number of files.. this utility works wonders!

Thank you

04 Jun 2011 Gamma Correction Gamma correction. Author: Pranam Janney hairan, zheli

it's not very good..i can't run it

14 Feb 2011 Gamma Correction Gamma correction. Author: Pranam Janney Luca

ok nice program, but how do you evaluate gamma?

12 Nov 2010 Gamma Correction Gamma correction. Author: Pranam Janney KAYA, Ă–mer

All you need... is one piece of line...

to control that line you need 30 of it;

good example of that...

In absence of a reply to my question...

08 Jun 2010 Seed generator using 'current' World Population count Generates a seed that could be used to set the state for random number generation in matlab. Author: Pranam Janney Campbell, Rob

Someone correct me if I'm wrong, but this submission isn't doing what it's claiming to do: The seed is just the starting point for the random number generator. Changing the seed in the way described above will give a different set of pseudo-random numbers but it won't make the series of numbers itself any more or less random.

In situations where you want a new random seed then either population or CPU time are equally valid. World population is basically just an exponential function of CPU time so both are predictable. However, in selecting a new random seed the predictability isn't relevant (unless you're doing cryptography), you just want to set your random seed to a new value. Of course, there are also situations where you want the random seed to have the same value on each run.
