wait a sec you have 600 subs wtf?! your a underrated channel that would have 2 mil,based on this vid keep up the work and you will he big in no time ❤

[@BPGHchess]

Great video! I tried to also create my own chess bot for the tournament by sebastian but realised that I am just not familiar with c++ enough, let alone engine programming (only did in python). The videodecribes the steps you took to improve the engine in a very clear manner and I have definitely learnt a few things about programming a chess engine.

[@simplyindev]

Yeah it can be very difficult if it's not a language you're familiar with, but I'm glad you learned something

[@fortnitecool905]

Love the video bro u deserve more subs

[@lubengeorgiev5675]

When using iterative deepening it is a pretty good idea to include principle variation (best line from previous depth search). That way you will be searching the new depth muchs faster (most of the time). Also some heuristic to order quiet moves might help you a lot (history moves, killer moves). To increase the depth you have two options: make it search faster (more nodes per second) or make it prune branches. If you want to prune more you can add null move pruning for not too many tokens used. A good idea also might be late move reduction (you cut the depth of search of moves after first 4 for example). The downside is if you do not succeed you are forced to reasearch at full depth or full search window.

[@simplyindev]

These are all some good ideas for improvements. I didn't mention it in the video but when I submitted I was using 1023 of 1024 tokens so I ran out of space to add anything else in without major optimizations

[@lubengeorgiev5675]

@@simplyindev Yeah the tokens are pretty limiting. Maybe 2048 tokens would allow for some crazy strong bots. What was the elo of the 1st place bot btw? I think if there is another competition I might be able to get top 10.

I use motion canvas which lets you create animations through code

[@CryptiCryptoAIM]

I don't think you can make a reinforced learning ai in 1024 tokens because this way you could make an infinitely good bot, just by pretraining.

[@Lisanicolas366]

[@Prometheus4096]

Very cool you documented your bot. I only saw the competition after it ended. I always wanted to try program a chess bot. So with this very nice C# framework and everything but the move search implemented, I also gave it a try. I went 10x over the token limit as the competition is over. But I am gonna try my bot vs yours. I had so many bugs in my bot. When it is searching a million positions and you have 10 000 lines of code, figuring out wtf is going on gets really hard. I am new to C# and I don't know how to code with little tokens so I think I would have failed hard at the competition. Maybe if there's a 2048 token limit competition I will submit something. That said, your no of positions evaluated at 4:51 seems wrong. It goes up exponentially, meaning you search until depth 5 almost instantly, dept 6 takes a while, and depth 7 is basically not achievable. Without move sorting, many positions have 30 legal moves, so it goes n^30. And with good move ordering, you can get to 5 to 15 branches added for each depth.

[@simplyindev]

I'd be very interested to see the results of that game! Yeah I knew my phrasing of exponentially was not technically correct in the math sense, but I was just using it by the definition of a more rapid increase. Same thing with my use of depth vs ply is chess coding was wrong, but I think depth was much more understandable to people

[@GuvBubbs]

This was great

[@goatguymanperson9961]

This was great

[@klatchabobby]

Making my own chess engine is a dream I have, but I unfortunately have no coding experience beyond one high school class of C# from which I've retained nothing

[@simplyindev]

That's alright, you'd be surprised how little coding knowledge you actually need to get a basic one working

[@kylebarvel]

I thought this meant the ai can control a column file in a board

[@simplyindev]

I can understand the confusion, I didn't even think about that 😂

[@oscareditedthis]

​​@@simplyindevThat actually sounds like s good video. Imagine, one half of the board has a good AI, and then other half has a different AI and they need to somehow coordinate their attacks. Edit: I don't mean black has 1 AI and white has another. I mean black uses 2 AIs but split between the board.
