The Game That Learns

[@Vsauce2]

I wanted to respond to two types of comments that have appeared more than once. I read all the comments and really appreciate when you all dig deep into these topics. First, we're missing some matchboxes because we don't actually need them! Some matchboxes work for two scenarios -- once for the board position they display, and also for the board position that is a mirror image of it. The computer learns both board positions at the same time, but yes, at first glance it appears as though I just left some out. Martin Gardner didn't think they were necessary, either. Second, Hexapawn is a much simpler version of chess, so terms like "checkmate" and "stalemate" aren't exactly the same. They're simpler, too. In chess, checkmate is achieved when there is no way for your opponent to move without the king being captured. A stalemate occurs when a player has no legal move. A stalemate results in a draw. So, when that occurs in Hexapawn, it has the trappings of a stalemate but has the result and the spirit of a checkmate -- the win is awarded to the player who moves in a way that creates a stalemate for their opponent. Because the situation results in a win instead of a draw, I thought it was more appropriate to compare it to checkmate, though it may have been clearer to avoid the language of "checkmate" entirely.

[@Gravedigga63]

TheEverydayWizard it wouldn’t be hard to extrapolate this idea into what machine learning is used for today. Imagine if Kevin himself is a machine that can play thousands of games a second, a much more complicated “game” could be solved by the machine very quickly. Although usually it’s not a game, it’s something like recognizing whether a picture contains nudity or not.

[@Gravedigga63]

TheEverydayWizard you’re right, this oversimplifies how machine learning works, but it’s a a pretty good introduction. You would need some pretty advanced programming understanding to comprehend how it is being used in more advanced systems. But the basic idea is essentially the same: a program “evolves” by keeping what parts of it get rewarded, and removing which parts of it are punished.

[@itripleo5780]

[@ZachAttack6089]

I thought about this as well. Technically I don't see why it wouldn't work the same way as Hexapawn, but in reality it would be impossible. Hexapawn has 3 pieces per player and is guaranteed to end after at most 7 moves, so you only need 24 boxes for the 24 possible scenarios. In Chess, on the other hand, you have over 100 million possibilities after just 6 moves. The "matchboxes" for this computer for all scenarios would need an impossible amount of storage.

[@lythd]

thats just infeasible, its nearly impossible for you to get to the same exact position again, so the knowledge is useless. there are so many possible games that its impossible to just play them all. this is a rudimentary technique that only works on simple games that you can easily go through all the combinations.

[@grimmsoul3096]

probs somewhere close to a year

[@lythd]

@@grimmsoul3096 not even close. it’d be done by now if thats the case. the computer would have to play atleast each board position with each possible move. if it could be solved google’s alphazero would have done it. we are a far way off. maybe possible if someone ran one of the big super computers for a year but id still be really hesitant to say so.

With tic tac toe, if you go first you will always win or tie unless you make a mistake. The game will result in 3 outcomes. You win early because they make a mistake, you win because there are 2 lines to block with one move which they obviously can't block both to, and a tie due to them also knowing the game and blocking one of those potential win paths early on in the game, limiting you to the first scenario, or a tie..

At first, it has no idea what to do, but after lots of trials, it gets to a point where it will never lose, only win or tie. Not only will it learn not to make a losing move, it will learn not to play into a potential impossible situation, going back as far as 2 moves. I also made it so that when it plays a winning move, it learns to only play that move.

my favorite thing is how this guy doesn't have some fancy intro with music and an animation, he just goes VSAUCE!!!!!!!

[@zakki5630]

Matt Parker did a similar thing using matchboxes for tic tac toe

[@dingalong14]

Thank you for this comment, I assumed this video was going to be exactly the same thing and would've skipped it.

[@brachypelmasmith]

and to be honest his was better

[@phiefer3]

Matt actually built Menace, this is a simplified version of it.

[@kroen]

But tic tac toe is way more simplistic. Anyone with half a brain cell could easily become good enough so that every game ends in a tie- even against the smartest computer.

[@brachypelmasmith]

true, but it's also a game you are much more familiar with and computer's progress can really be seen

Nostalgia! Back in high school (mid-1970s), I wrote a Hexapawn program. I modified it so that the board size could be made anywhere from 3x3 to 8x8 and it would remember all the results for each size board.

love your vids! Also, 2:58. In chess, when opponent has no legal moves it's called stalemate and counts as a draw

Thank you so so much! It's almost like YT knew that I made hundreds of Google searches about genetic algorithms and symbolic learning, and is now suggesting me this amazing explanation! You made this seemingly endlessly complicated subject seem simple, for which I am very thankful!

[@jbrysoniii]

Kevin, fantastic video. As a software engineer I can really appreciate when someone teaches a concept like machine learning in the tangible world. I’d love to make this for my kids and nephews, any idea where I can get the images for the matchbooks?

[@Vsauce2]

I posted the templates for you to download for free on Twitter!

I've been wanting to program a genetic algorithm in Java, and this video helped me understand the concepts of it. I think next time It'll turn out better. Thanks for the amazing video! :)

Standupmaths did the 300+ matchbox MENACE a couple years ago

[@pierrestober3423]

I knew I had seen something similar on youtube already, but I didn't remember who had done it, thank you.

[@Duraludon884]

Standupmaths made a copy of MENACE and had it play tic-tac-toe with many people during the International Maths Festival (I think). He did both punishment and rewarding- if the next turn lost, remove that bead. If that move won, add another bead. The experiment was done, reset, and done again the next day, and the results were different.

So glad that Martin Gardner invented hexapawn! He was a true lengend.
