  • 大実験!ChatGPTは競プロの問題を解けるのか (2024年5月版) - E869120's Blog

    1. はじめに 2024 年 5 月 14 日、OpenAI 社から新たな生成 AI「GPT-4o」が発表され、世界に大きな衝撃を与えました。これまでの GPT-4 よりも性能を向上させただけでなく1、音声や画像のリアルタイム処理も実現し、さらに応答速度が大幅に速くなりました。「ついにシンギュラリティが来てしまったか」「まるで SF の世界を生きているような感覚だ」という感想も見受けられました。 しかし、いくら生成 AI とはいえ、競技プログラミングの問題を解くのは非常に難しいです。なぜなら競技プログラミングでは、問題文を理解する能力、プログラムを実装する能力だけでなく、より速く答えを求められる解法 (アルゴリズム) を考える能力も要求されるからです。もし ChatGPT が競技プログラミングを出来るようになれば他のあらゆるタスクをこなせるだろう、と考える人もいます。 それでは、現代最強の

        A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog

This article introduces free monads and explain why they are useful in Haskell development. To whet your appetite a little, free monads are basically a way to easily get a generic pure Monad instance for any Functor. This can be rather useful in many cases when you’re dealing with tree-like structures, bu

A year ago Jake Edge made an excellent summary of the discussions so far on Rust for the Linux kernel and we (or rather Miguel and Wedson) have made further progress since then. For the record I think this is overall a good idea and worth a try. I wanted to add some background tha
