Pseudorandom number generation predictability Can you expect with certainty that any pseudo-random number generator will produce the same stream with a shared seed?
Take (hypothetical) seeded deterministic PRNG algorithm Gen1. If you use Gen1 to produce a stream, and I use Gen1 with the same seed, I will get an identical stream. As per Wikipedia's definition, a PRNG is deterministic.

Now consider another hypothetical seeded deterministic PRNG Gen2, which uses a different algorithm than Gen1. If I use Gen2 with the same seed as before, there is no reason to expect the same stream to result.
