How computers generate RANDOMNESS from math

[@agrimpuriya2585]

Absolutely love your video. I was coding in Python, and i was using "random" library when I suddenly realised "How is a computer, the most pattern based machine in the world, able to generate randomness?".

[@nemiw4429]

Same. 0:31 Im watching the video, never looked into it, but Im pretty sure its impossible. 1:07 ok, thought so. U cant explain a machine "give me random".

[@KarTandir]

i was studying wave function of an electron an suddenly asked myself the same question lol

[@user-rm2qj2jh4l]

This is such a good, brief yet detailed explanation! Thank you!

[@christophertadeo6120]

Pseudo random is what we call it in computer science...

[@ThankYouESM]

I thought it was always from current milliseconds by 32 decimal places.

[@king_james_official]

depends what algorithm the software is using. a lot of time it combines time, mouse movement, cpu load, ram usage, maybe even microphone input

I'm trying to find the type that can create organic art very fast... hopefully each out of a billion numbers like perlin noise combined with mandelbrot

[@YoungFellow]

Very nice explanation. Thanks Tony!

[@MrLottoLife]

Which means slots are not unpredictable and random. I've been studying slots and patterns and I've noticed patterns that tend to win even amongst all the "randomness."

[@MR_GREEN1337]

Mate, you're incredibly good! Thanks a lot and wishing you the best!

[@Ish21823]

nah

[@mohammadjadallah9813]

Okay… but where do you get the seeds from? You’re just saying “pick a number”, isn’t that basically random?

[@TonyZhang01]

Yeah so the only way to do that is getting it from somewhere else (time of day, temperature, increasing the seed by one each time, etc). Or you can just use the same seed and continue with the sequence of numbers

[@talkingmurga5554]

Yeah, generally in multiple programs the seed is set by the user. In other cases it is taken from time or/and hardware data.

[@KarenEaker]

I would use a method that leverages "human randomness", such as a value calculated from a combination of the mouse position, time of activity, and number of mouse clicks multipled by 3/4 of the cpu temp.

[@ibrahimsoukak437]

That was my question too. I think I need to try that algorithm myself to understand it better

[@kkalyan5569]

Hey,nice explanation and i really appreciate your work. Nice rendering of manim ,it would be really helpful if you can share the manim file for the animations in this video.

Great video. I hope you make more!

[@Lea-js9jw]

Oogwey was right all along

[@BrokenG-String]

For more secure randomly generated numbers, other than changing the seed, is it possible/wise to also change the mathematical equation every cycle?

[@TonyZhang01]

I’m pretty sure that the numbers for the algorithm itself are chosen specifically to work well, and it’s pretty easy to accidentally use a equation that just gives the same number over and over. Also just choosing the seed means that you will have an equal distribution of the numbers

[@JumpingJack-w2l]

Length of random data you feed in determines true randomness of the output. You can reduce true randomness by choosing inappropriate algorithms but can't increase it. If there is desire for more secure random numbers, I think focus should be on getting more randomness from some entropy source(s), while algorithms also important, but they can't do what they can't do, i.e. provide true randomness from nowhere.

[@iliapopovich]

Thanks for the video, It's a very good example, but the simplest way in my opinion is using logic gates output from flip flops.

[@playful1]

Lotto results seem to mention Random number generator. Whereas they always are Specific number generators.

[@matiasvlevi6647]

I like the animations very well explained.

[@prodoxel9578]

Thanks for the information!

[@keki4578]

I lost some hairs trying to think a way to program randomness. Turns out, there is no way. underwhelming, sad, distraught, depressed, furious Thanks for the video

[@error404m]

Factor the number of hairs lost into the generator.

[@alessandrorossi1294]

At 3:01 you say Xorshift is “more robust” than a Linear Congruential Generator without defining in what way that you claim Xorshift is “more robust”.

[@TonyZhang01]

That's fair, I guess at the time I just meant a more widely used and more complex algorithm

[@alessandrorossi1294]

@@TonyZhang01 ok. robustness is defined by asymptotic analysis on an algorithm and is not a synonym for "popular" or "good". it is a property that will be robust with respect to some variation that winds up not effecting the property. this is important since usually some imperfection, randomness, or noise in your initial conditions is considered likely, so you want a property of an algorithm to be "robust" against imperfections in your initial assumptions, as opposed to being "highly sensitive to initial conditions". however for a pseudo-random number generated you don't want the numbers produced to be "robust" you would prefer them to be highly sensitive to initial conditions because you want them to be hard to predict or to say anything else. the only property of a pseudo-random number generator you would want to be robust is its ability to pass statistical randomness tests over multiple trials. check out martin lof randomness

[@Bonjemus]

Nice explanation!

[@chandmalsuthar3129]

Hello sir (91 club colour predition) a game janrate 0 to 9 rendom number computer method Is it possible to guess what the next number will be?

[@objectivecompleted-9474]

Random numbers: Gargoogolchime = 10^2,000 Gogolbong = 10^50,000,000 Guppyminutia = 10^-20 Guppyminex = 10^-10^20 Guppychunk = 10^15

[@utarajat]

I'm new to programming. So when we use the random() method in python how is the seed determined there?

[@thekarotte1625]

Very good explanation, thanks.

[@wilfriedkamdoum]

The Xorshift is more comprehensive

[@nasrogalili]

Thank you so much for explaining! Can you please tell me what's the name of the texts transition? Like the effect name..

I used www.manim.community, the same animation thing used by 3 blue 1 brown. I actually made a whole video about it: kzbin.info/www/bejne/hYC7npV4Yrqko8U

Thanks! I now understand xor generator :D

[@pwjaiter6277]

It always annoyed me in c hoe relatively hard is is to get a random number

[@tylerwatrouse8602]

When I realized this concept it kinda led to understand the idea of 'consequenstialism' or whatever. I geuss I believe in destiny

[@jacc7203]

Thats determinism. Consequentialism is the idea that what makes an action wrong is its consequences. For example, a consequentialist would say that punching someone is bad because it causes them pain.
