Hey everyone, hope you enjoy the video! Quick note - I noticed some slightly distracting compression issues after uploading, where squares of the chess board would sometimes blur together and flicker a bit. The only solution I could find was upscaling to 4k, so if you have the bandwidth I'd recommend watching in 1440 or 2160p. By the way if you'd like to play against the AI, you can find downloads here: sebastian.itch.io/chess-ai And source code for the project is over here: github.com/SebLague/Chess-AI

I now firmly believe that if a piece captures your rook at a time when you otherwise could have castled, you should be able to respond by castling with the capturing piece. Assuming it's a bishop or knight, of course, anything else that would be checkmate. I have no idea what impact this rule change would have on the game but I want to find out!

Yea, but I dont quite agree with the quote. What if we use the integer (which is basically a hash of the position) to find possible transposition candidates, and then check the candidates by using the FEN-String? We basically get the speed of the hash and the uniqueness of the FEN.

@UnboxTheCat

3 жыл бұрын

​@@Freakschwimmer I don't think checking the collision by comparing with FEN string is worthy at all, here are some of my arguments: #1 it is almost impossible to reverse the hash back to the original chess position, that's why it is called hashing. #2 even if reversing the hash is possible, converting it back to FEN string is just ridiculously expensive. You have to go through 8*8 = 64 elements and generate a new FEN string based on that. #3 Comparing these two FEN tags are also expensive, imagine running cmp instructions by up to 32 times just to check these two strings.

@randomizednamme

@@UnboxTheCat you don’t need to reverse it, you just store the FEN alongside your real data, like a dictionary you would have buckets instead of a single element in case of a collision

@UnboxTheCat

2 жыл бұрын

then in that case why dont u just store the FEN instead? Because in CCRL or other chess emgine competition only allows you to have a tt table size of 256/512 MB, and you will NOT have enough room if u store along the FEN. Plus in order to store the FEN, u have to generate the FEN for each position as well, which is really slow. As a result, I have never seen any engine's imeplementation like that(or even if they do, their depth won't go past 8 without aggressive pruning I promise you). Modern top engine usually just store the Zobrost hash value % transposition table size as key, and the position eval, hash move, and alpha beta flag, as you may see in stockfish's source code. Chess engine requires good performance in terms of speed, not good looking fancy code that uses std hashmap. Correct me If I am wrong

Maybe when a planet goes to generate plants it would use a grid mesh over the surface of the planet. Then each type of plant would have a sort of value and you cant have too much value in a certain sized area, and due to environmental constraints certain plants cant spawn in certain areas. Maybe the way it goes about spawning them in would follow a similar pattern of looking ahead in time with spawning to maximize the total value of plants on the planet? This is about the best I can come up with and I'm not sure it makes much sense. . .

Years ago, on Scratch, the big trend was chess projects. There were a lot of really good ones, that constrained both sides to legal moves. There was one thing nobody had managed, though - an AI opponent. This was a whole thing, Scratchers talking about if it was even possible, etc. Then, a user named Midecah showed up. No previous projects, no avatar, nothing. Midecah uploads the best chess project anyone had ever seen on Scratch. It had a detailed description, pseudo-3d chess pieces... and an AI opponent. Hell, it even had a _loading bar._ It was a bit buggy, but the scope of the project made that a bit of an inevitability. Midecah hasn't uploaded anything since, nor have they responded to comments or anything. They just... showed up at the perfect time, gave us the holy grail of the current trend, and rode off into the sunset. Godspeed, Midecah, Godspeed.

This is truly a wonderful video! So informative and well made, I actually come back to re-watch it every so often, just for the pure entertainment value. :) Aside from that... it has inspired me to try my hand at creating a chess engine of my own, in C++ and from scratch - I'm calling it "DLC-LUNA" and I'm pretty happy with the results so far. About a month's worth of work was put into the project, and I'm at a point where it can easily defeat a 1500-1600 ELO StockFish bot. Now, of course that's not really "good" by any means... more like, pretty much average. But it's more than I ever hoped to achieve in this short amount of time anyway. The last thing I'd need to add would be an opening book... and from there, it's basically just computing speed optimization. But as I said: I didn't even expect myself to get _anything_ done to begin with, so this is already a huge success :D all thanks to your inspiration. Thank you. :)

Very impressive and clean execution, definitely will try refactoring some code in my game based on this!

I’ll need to learn how to play Go first! :D The extra bit is just so I can have ‘no colour’ as an option. Was mildly useful in some cases to be able to represent a pure piece type, with no colour associated.

Also, it's useful if you wanna have 3-player chess. Or even 4-player. Hell, give it a whole byte so we can have last man standing.

The way you elongate the final syllable of some words makes you sound like an old school film villain/vampire/evil wizard (it's awesome)

Man the amount of work you put into this video and the chess programming of course is impressive!

I just love 11:00 it´s interesting how a small mistake in programming makes such weird moves possible.

Very interesting video! The approach you talk about around the 28:00 mark reminds me of dynamic programming. Keep up the videos, they are really fun to watch!

Very very interesting from so many aspects. Thank you for posting this video. Awesome!

Catastrophically misjudging almost every situation? Sounds like my chess.

"The computer thinks its doing fine until it realizes it needs to start sacking pieces to prevent a checkmate". same computer same..

I remember coding my chess engine when I was a sophomore and came across several problems that you mentioned. So fun.

this is an incredibly well made video, Bravo. This is the perfect video and subject level to show someone what programming is.

Finally... This made my day even before watching...

7:49 Ah yes, a very common endgame situation.

A way to make the pawn structure thing better is by making it more favorable to have pawns in the center when there are more peices and try to get them to protect eachother

Thank you for this. As someone who loves programming machine learning AI, I've always wanted to program a chess network that uses Q learning to both memorize board positions, as well as piece relationships but my weakness in code is tree searches because I've never programmed a lot of things that used searches, and in chess it's unavoidable and you have to use them. the explanation of alpha pruning really helped me and your demonstration of code definitely will make the transition easier as I can see a way it's programmed so I can modify it for my own use.

At 2:28 Is it Nf7+, Kg8, Qe8+, Qf8, Qxf8++? Also, thanks for another great video! :)

wait I need time stamps for these I missed a lot of the video ;-;

I've been following along with your chess videos, and slowly implementing some of the various features myself in Java (Didn't end up staying with Java though). In between watching the video and reading your code, I'm always astonished about the little details that you change along the way. The one that stood out to me the most in this video is where you changed the number for the pieces after realizing that bit-wise operators would work easier if the sliding pieces were one higher than what you initially set them to, which is a very clever change. Anyhow, thank you for the little kick of motivation to refine some of my lackluster coding skills! I hope to get a bot that can at least beat me.

The idea of using iterative deepening to control branch order for alpha-beta pruning is something I've never considered before, but that's actually a super clever trick. Now I feel like my prof should've talked about that in class.

The best instructional video on chess programming ever!! Reasonably short, with all basic staff in place with proper level of detail to give the idea of what is this journey about... Bravo!

Great video! You should plot the ELO rating of your Chess program against each upgrade you make, e.g random moves, to basic heuristics, to the king safety and knights preferred squares etc. Might take some work but would make for a very interesting follow up video (:

I've been coding for 3 weeks and 90% of this goes over my head, but I am trying hard! Great stuff and very interesting!

Awesome video, it was really enjoyable to watch. Nice work!

I just realized how Sebastian spaces the parentheses in his method calls... I can never un-see that now... I want to die...

@@guiorgy suckerpinch Sebastian Lague crossover? that would be amazing

Honestly that checkmate at 7:48 is pretty nice for a random match. Checkmate by a knight, with every other friendly piece on the board contributing to keeping the king pinned. The other knight guards f6, the rook guards d4 to f4, the queen takes care of d4 to d6, and e6 and f5 are taken care of by the bishop (and the mating knight also guards f4)

This is actually really well made. Instead of a very basic AI you went really deep and made something that's quite good.

This gave me flashbacks to my undergrad dissertation, writing a '3D' chess variant with time as the third dimension. Figuring out the legality of moves was really horrible code, because you could do things like moving a piece back in time to take a piece that would go on to threaten the king in the present. So figuring out if a move actually got you out of check took ages.
