However it is cool that this overfit does not allow you to compute the final input for which there is no known output.
This therefore forces the creation of more general solution rules.
While in some cases solutions can work for any input, in many others they require specific assumptions about input, but the model could simply check that the assumptions apply to all inputs and use them for the final algorithm.

AI code generation benchmark in which part of the benchmark includes producing a formal Lean proof of the implementation. Sweet.

We combine large-scale pretraining with reinforcement learning to create models that can rederive and learn from the entire corpus of human mathematics. Our goal is automated mathematical discovery: AI that does the creative, generative work that was previously only possible for the world's best researchers—and can be deployed on the hardest problems in science and engineering.

Suppose that today is June 1, 2025. We call a date "square" if all of its components (day, month, and year) are perfect squares. I was born in the last millennium, and my next birthday (relative to that date) will be the last square date in my life. If you sum the square roots of the components of that upcoming square birthday (day, month, year), you obtain my age on June 1, 2025. My mother would have been born on a square date if the month were a square number; in reality it is not a square date, but both the month and day are perfect cubes. When was I born, and when was my mother born?

Pinned article: Introduction to the OurBigBook Project
Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

Source. - local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
