I made a chess engine today, and made it fit within 2KB. I used a variant of MinMax called Negamax, with alpha beta pruning. For the board representation I have used a 120-cell "mailbox". I managed to squeeze in checkmate/stalemate in there, after trimming out some edge cases. I am a great fan of demoscene (computer art subculture) since middle school, and hence it was a ritual i had to perform. For estimating the Elo, I measured 240 automated games against Stockfish Elo levels (1320 to 1600) under fixed depth-5 and some constrained rules, using equal color distribution. Then converted…

As part of the annual JS13K games challenge, I've put together a pretty large (but small-in-code) Metroidvania game that fits in just 13KB of compressed Javascript. The source is available here: https://github.com/arikwex/infernal-sigil NOTE: the current head of the main branch is at 13.6KB due to quality of life patches. The legit 13KB version is tagged in github. Useful hacks: - Using Roadroller (https://github.com/lifthrasiir/roadroller) for compression - Compressing the map data as grayscale PNG paired with some code generation. - Using procedural…

Some months ago @andrewrn tried to create a Wordle-style site for order-of-magnitude thinking. This was a wonderful idea, but the actual site was somewhat over-engineered and confusing. (https://news.ycombinator.com/item?id=43632278) In the past week, I looked at this idea again and built a very simple site which gives you a new Fermi estimation question every day: How many new cars were sold in the US in 2024?; How many humans have ever lived (including those currently alive)?; How many chickens are slaughtered for meat every year? To win, you need a guess within ±20% of the…

Two years ago I sat down to build a chess engine for my kids' Christmas present. Wanted it to play badly enough to be beatable but not randomly bad: different styles so they could choose what to face. While building those styles I noticed the choices started looking like actual historical players' tendencies. Went looking. Turns out: given enough games from one person, you can extract enough of their decision pattern to reproduce it. Two years later, 41 players, ~3,000 games each. Tal sacrifices unsoundly. Morphy attacks like it's 1850. Capablanca grinds endgames. Same engine underneath,…

I had an idea on a competition in a highly constrained environment: 32x32 matrix, with bots running code you write! The live site is https://kingofthegrid.com/. Each bot emulates Z80 CPU and they all get equal execution time, so the most efficient algorithm wins. Bots can move, eat, clone themselves, and most importantly, survive the competition. Each submission, leaderboard is re-calculated, such that each participant has a match against each other, and the bot that makes the most wins gets to the top. It includes includes an online in-browser IDE:…

I built 1e4.ai - a chess web app where you play against neural networks trained to mimic human Lichess players at specific Elo ranges. There's a separate model for each 100-point rating bucket from ~800 to 2200+, and the bots not only choose human-like moves but also burn clock time, play worse under time pressure, and blunder in human-like ways. Live demo: https://1e4.ai Code: https://github.com/thomasj02/1e4_ai A few things that might be interesting: - Trained on almost a full year of Lichess blitz games, around 1B total games - Architecture is an a small…
