Ciro Santilli's fork of ARC-DSL merging all pull requests needed to make tests run again on Ubuntu 25.04.
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:
- dsl.py: defines the transformations as Python functions
- solvers.py: defines solvers for the 400 ARC-AGI-1 training problems
Intended usage to run the solvers seems to be:Unfortunately this blows up on Ubuntu 25.04 on
