ARC-DSL by Ciro Santilli 37 2025-10-18
This interesting repo defines a set of input transformations that can be composed together into programs to generate the solve ARC problems.
It does not appear to have any program synthesis: it only defines the DSL and then provides manual solutions to the problems.
The README is lacking as usual, an overview of the files is:
Intended usage to run the solvers seems to be:
git clone https://github.com/fchollet/ARC-AGI
cd ARC-AGI
git checkout 399030444e0ab0cc8b4e199870fb20b863846f34
git clone https://github.com/michaelhodel/arc-dsl
cd arc-dsl
git checkout 635de4902a5fb4e376f27333feaa396d3f5dfdcb
python main.py
Unfortunately this blows up on Ubuntu 25.04 on test_mpapply apparently due to a Python 3.12 issue and the pull request github.com/michaelhodel/arc-dsl/pull/7 has been ignored for more than one year, so the project is largely dead.

Updates / ARC-AGI-2 by Ciro Santilli 37 Created 2025-10-18 Updated 2025-10-21
I've created a quick fork of ARC-DSL which defines a hand crafted Domain Specific Language (DSL) approach to help solve ARC-AGI problems.
I basically just merged outstanding pull requests on the original repo that were needed to make things run.
It would be cool to see if those rules also solve ARC-AGI-2 problems well, but lazy now.
ARC-AGI-2 is a very interesting benchmark which mixes some symbolic and other visual elements, and is readily solvable by non-expert humans, but has so far resisted transformers to a large degree.
Part of me would like to focus more on less visual aspects of AI, but it is still of interest.
It is funny how many early (semi)-retired fintech/bigtech bros that are interested in the project, I saw several of them on the forums.
I'd be tempted if I were in that position too I must confess. Maybe in 15 years time for me the way things are looking.
Kudos to these people who do something cool and open when they don't need money: www.reddit.com/r/Fire/comments/15x4w7r/comment/jx7dn16/ It is also the case of Jimmy Wales from Wikipedia for example, who used to work in finance.
