Thankfully, we won't actually have to solve all 930 individually. transfer.py is a wonderful thing.

There are a number of still lifes that look like they'd be solved with a transfer of this, for example:
Excellent! A recent run of transfer.py brings us down to 857 unsolved xs19s.

Re: Using ML to synthesize complex constellations

That said, sometimes a rigorous algorithm (such as a SAT solver) needs to make an arbitrary decision (such as deciding which variable to choose as the next branch-point), and those arbitrary decisions can be made by machine learning.
