Re: Oscillator Discussion Thread

Did you try sldiff? That would give you the closest naturally-occurring still-lifes if you feed it with the D2_+1 textcensus.

Okay, but why can't we host everything on pages like "RLE:long10boat" on LifeWiki?
Then it takes a lot more effort to download the RLE itself (I don't believe there's an easy way to access the raw contents of a wiki page).

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.
