Build a Simulation in 5 Min

We're going to build our own version of Conway's famous Game of Life in 60 lines of Python! The Game of Life simulates biological evolution and is an example of how mind-boggling complexity can emerge from just a few simple rules. This video isn't straight up machine learning, but instead an intro into this way of thinking. If the universe works this way, our brains must as well. I truly believe that the master algorithm behind human intelligence will be much simpler than we expect.

Just found your channel, nice videos and ways of making them. They are very entertaining to watch with alot of knowledge in them. Keep it up, this channel will get big!

[@SirajRaval]

thanks Davey!! Please re-share if you found it useful!

[@panagiotispetridis7961]

Those video are getting better and better!

[@SirajRaval]

thanks!!

[@robinkohrs8097]

thanks so much!! Just one question: What do the testx and testy in the healthy_neighbors-function do? I thnk its for the border condition, but I'm not completely sure...

[@benhayz1]

Watching all your vids in a playlist today. Keep up the great work!

[@SirajRaval]

Thanks Ben, glad to have you on board

[@MichaelBuergerArt]

Is it wrong I'm sad this channel is growing? These videos are so great, I just want them for myself :D

[@SirajRaval]

haha! Thanks so much. I feel you, i'm like that when it comes to fashion styles.

[@MichaelBuergerArt]

Sirajology oh cool! you responded, hope you don't stop when this channel gets larger, kinda thing happens a lot sadly.

[@FuzzyOne2007]

Hi Siraj, love your videos man, I have a question, I'm looking to get into machine learning and my first task I want to accomplish is finding an equation to a two column problem, for instance say I have data like below, I have about a 60% complete dataset. 0000000 = 1234 0000001 = 6789 and so on to... 9999999 = 3434 How do I go about finding the missing rows, as far as I understand I need to do supervised learning, with say 80% of my data to train a model and the other 20% to validate. I'm using Azure to play around but hitting a complete brick wall, do you have any tips for me, is ml even the right choice for solving this?

[@SirajRaval]

Thanks! Yes this is an ML problem. Predictive modeling. Treat the first column as x values and the second as y values. So each row is a coordinate pair (x,y). You want to plot those points on a graph and find the line of best fit. See this stackoverflow.com/questions/22239691/code-for-line-of-best-fit-of-a-scatter-plot-in-python you can do this in python

[@amadeusml]

Thanks! The speed with which you went through the code worked a lot better for me in this one (seemed slightly slower, I had to pause a lot in the other videos).

[@SirajRaval]

thanks for saying this, very good feedback i'll keep in mind for future vids

[@bballfanmobile2544]

I'm trying write this program under macOS X, using Canopy Python 3.5. What libraries can I use to control the screen???

[@spawnermaster3794]

Congrats on 10k!

[@SirajRaval]

thank you so so much. holy shit i'm so happy, just getting started!!!

[@lumlins2104]

Ha ha now look at you

[@vybhavab]

I did this in java for my APCS class. It was so fun! Great video btw!

[@SirajRaval]

Dope, isn't it fun?? thanks

[@vybhavab]

It's so fun!

[@wyattb3138]

I’m too dumb to code 😪

[@danielmuriithi8486]

Great content awesome as always Siraj

[@manuhortet]

Great! Amazing videos bro, keep on the good work!! Subscribed!

[@SirajRaval]

Manu thank you!! much more to come

[@Trendlitesocial]

just got into your series and i like it. however i am a complete noob to coding as i didn't go to school for it. i am taking a udacity course and trying to follow along with you as i learn coding and ml. Do you think this is ok or would you suggest i learn to code first then come back.

[@SirajRaval]

follow along with me at the same time is best

[@furkankaynar6491]

Your energy is awesome

[@liambond5653]

I was trying to follow the code, but it gives no module named terminal error ... can someone point me in the right direction?

[@SaikatBasak]

Awesome video. I'll try to do it in Octave and share.

[@SirajRaval]

good call

[@exec9292]

Absolutely awesome!!!!

[@SirajRaval]

woot woot thanks!

[@ignaciotonolidemaussion3249]

Hi I tried out but there is an error at line 2 "from terminal import *" ImportError: No module named terminal I'm working on macOS El Capitan

[@JoshuaShope]

only works with python2

[@thesource3376]

The error goes away after typing "pip install terminal" in the CMD (command prompt).

[@hligfl]

me I do it but nothing happens. Indeed nothing is asked to be printed. Any idear ?

[@xus9380]

Can you make tutorial about making a slot gaming game (slot result from random number generator)

[@choglog]

another great video!

[@SirajRaval]

Thanks Exor!!

[@larryteslaspacexboringlawr739]

thank you very much for video about simulation using python

[@diegoalpizar6857]

Great video!

[@xxXXCarbon6XXxx]

You can see interviews with Conway on the Nuberphile channel

[@SirajRaval]

yes!! that is a great channel

[@hugoporras14]

Hey Siraj, any way of doing this on windows, i wouldnt like to buy a Mac to do this. :(

[@Beyblade0battles]

Yeah man of course you can do it on windows. I dont exactly know how but im 1000% sure you can do this on windows. its just a python program. and you can use other programming languages to do this too

[@hugoporras14]

@@Beyblade0battles the thing is that terminal is a MAC OS library, And you cant use It on Windows

[@Beyblade0battles]

@@hugoporras14 ah ok. I'm sure there's a way to do this without that library

[@wyattb3138]

I just watched a SpaceX presentation on aerodynamics and combustion simulations.

[@44_bulldogT]

Brother, tried to run the code and it didn't work. Need help.

[@JoelWilsonthelittlen]

? what ver of python do u use ?

[@SirajRaval]

3.5

[@endlacer]

Line 36: Why do you set new_grid = grid ? new_grid is overwritten in line 33. No use assigning it, am I right? good job :)

[@santhosh3374]

bro i am sorry to say but i have to..that code contains several mistakes which include open and close brackets in several places for print function and few more...if i am wrong correct it...i am happy to accept it

[@angelthekind1595]

NameError: name 'get_term_size' is not defined also more variables im not sure if this is real

Nice! Game of life weekend!

[@SirajRaval]

yes!! It is because we say so!!

[@alifyz]

You are amazing!

[@SirajRaval]

thanks so are you!

yo cool video dude

[@puryteevee]

hey can you do this using turtle graphics?

[@SirajRaval]

yes

[@chinmayanaik1380]

raj it says syntax error

[@andrewhumphreys9020]

I know I post way too much on your videos, but can you make some sort of series where you challenge us to do some shit, python, nodeJS, whatever? And review our results, and maybe compare it to something you did? IDK. I just like being challenged to do shit.

[@SirajRaval]

no such thing, post away. this is a brilliant idea. i'm definitely going to do this for my next video. thanks so much!!

[@andrewhumphreys9020]

Sirajology :D.

[@andrewhumphreys9020]

at 2:20, before I even get into learning your python code it seems incredibly doable with minimal code. The hard part for me (with all code in general) is figuring out how I would do that. So I am going to walk around for an hour or something, and think how I could carry that out. (I always just get all these ideas for coding.. I don't want to think about anything else than how I can carry stuff out.. It is.. weired but awesome.)

[@andrewhumphreys9020]

Well, I have an idea of how it is possible. Just scan in a grid, and go check around a live cell and all of that. I can envision the code, but I am too lazy to write it out, as I am not super hyped about coding this. (Lazy, it is 9:51...)

[@andrewhumphreys9020]

Anyways, I am going to use youtube to advertise my new website. Everyone goto getgnulinux.xyz for advice on picking a Linux distro, or (at now, a small small selection) information on various shits.

[@SirajRaval]

no dude i feel you. i do the same. walking and thinking is the best

[@kacperozieblowski3809]

Simulation? Mate it is just simple game of life!

[@cameronbehar7358]

Excellent video as usual. Minor nit though: von Neumann is pronounced von NOY-men rather than von NU-men. German :P

[@SirajRaval]

thanks Cameron good call

[@danielhoward4333]

Okay but: singular == automaton plural == automata So, any individual cell is an automaton, and the cells together are automata ... See also: datum / data, criterion / criteria ...

[@SirajRaval]

good call, thanks

[@xPROxSNIPExMW2xPOWER]

this was one of my assignments, wayyyy worse that you made it out to be lol good times

[@SirajRaval]

How to create it without using a buffer matrix

[@CTimmerman]

google "sparse matrix"

[@clearmenser]

classic universe mate

[@SirajRaval]

such a classic

[@clearmenser]

You know about the turing complete 1D cellular automata from Wolfram, right? Or read "Pumutation City" from Greg Egan? Mmm automata.

[@anger42]

This isn't a video on creating a simulation...this is a break down of how someone else created a game...or am I missing something??

[@whatthefunction9140]

why would an advanced martian rover be made of iron?

[@SirajRaval]

iron isn't a bad material, i'm sure the curiosity rover has some iron in it

[@whatthefunction9140]

I was just messing with you :) thanks for the great videos!
