Independent Pseudo Random Generators Is it sufficient to seed a pseudo-random number generator (PRNG) with two different values to be able to claim that we now have two independent PRNGs? Or is it that we have to use two functionally different generators for that?
If you are using a cryptographicly secure PRNG with a sufficiently large seed. Then it is expected to be infeasible to detect a relationship between the random stream output.
If you find two carefully crafted seeds where the output streams then have some clear relationship it would be considered a (mild) weakness in the PRNG, and much more so with random seeds.
