Continuing where we left off in the previous article, about one month into the competition, our team was fully formed and busy golfing! Although we had some strong scores on individual tasks (as per the public scores spreadsheet), we were behind other teams on the number of tasks solved. Team “ox jam” had finished early: […]
I was privileged to be a part of the winning team in the NeurIPS 2025 Google Code Golf Championship, which took place August–October 2025. The goal of this competition was to solve 400 Python problems in as few bytes as possible (“code golf” refers to minimizing the length of programs). The problems consisted of grid-based […]
In this article, we’ll look at some techniques for how ordinary JavaScript code can be packed into a shorter program using Unicode. We’ll analyze 2:1 packing techniques, including some variations I developed that can sometimes do better than 2:1.
Why does 100/9801 equal 0.0102030405…? In this article, we’ll create fractions that evaluate to interesting decimal numbers and give a gentle introduction to generating functions.
This is a follow-up to my previous article about the Golf Horse “SIGBOVIK” problem. With great effort, I managed to save 6 more bytes. In this article, I’ll give an in-depth explanation of the additional techniques I used and how I discovered them.
The “SIGBOVIK” problem is the shortest problem in the Golf Horse collection. The goal is to write the shortest JavaScript program that prints out thirteen 64-digit hexadecimal numbers. Despite the apparent simplicity of this challenge, there’s still a surprising amount of depth to it!
In this article, we’ll take a look at an interesting connection between the 3-variable AM-GM inequality and the determinant of a particular matrix. We’ll see this connection also reveals when AM-GM holds for negative numbers, and it can be used to produce stronger versions of the inequality.
This is the sixth article in the series for Golf Horse: Wordle. I’ll go through some ideas for future improvements, and ideas that didn’t make the cut.
This is the fifth article in the series for Golf Horse: Wordle. We’ll build a very simple decompressor for JavaScript code to save a few bytes.
This is the fourth article in the series for Golf Horse: Wordle. In this article, we’ll go through some numerical techniques to find an optimum of a complex function.
This is the third article in our Golf Horse: Wordle series. We’ll take a detailed look at the context models and context mixing used in my submission.
This is the second article in the series for Golf Horse: Wordle. We’ll show how to optimally pack bits into UTF-8 JavaScript code.
This is the first article in the series for Golf Horse: Wordle. We’ll figure out how many bits we can theoretically pack into a valid UTF-8 file.
My first-place entry for a challenge to compress 12947 words into as little JavaScript as possible.
