What does seed value really mean?

Question

I got a picture that its some sort of alg generator. Can someone explain it further

Answer 1

A pseudorandom number generator (PRNG) generates numbers by starting at some arbitrary number (the seed) and applying a function to it over and over again.

Imagine the worst PRNG possible:

x -> x + 1

This generates the sequence 1,2,3,... if seeded with 1. It generates 8,9,10,... if seeded with 8.

Better PRNGs will do some more complicated maths, so the numbers look more random, but the concept is the same.

Note that when you seed your PRNG with the same number twice, you will get the same results.

Answer 2

Yes bro... Same answers for same seeds i noticed... Thankz for the reply
