Okay, title doesn't give a lot of information so please bear with me here. Forget the why, I just need to figure out how. I would like, given an array of floats(such as those that would be generated by perlin noise) to be able to extract what seed would be used to generate said set of numbers. I only think this is possible because perlin noise uses pseudorandom number generation, and I assume since pseudorandom numbers are generated from a seed and a process it should be possible to reverse the process. However I understand if such a prospect is just not possible with the way modern computing works. Thank you for your time.
