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.

The timestamp is 2019-06-24, so the "Well would you look who's back" is slightly misleading.

I agree with wildmyron.

It's the 500th most common 14-bit still-life (out of 619), with 181 natural occurrences:

15G for a 160-bit still life ; as far as strict still lifes go, this is a lower glider-to-bit ratio than anything I've ever seen: (taken from the first C4_1 soup) x = 57, y = 57, rule = B3/S23 13bobo$14b2o$14bo3$26bo$27bo$25b3o3$25b2o$26b2o$25bo$56bo$54b2o$55b2o 2$36bo$34b2o$35b2o2$21bo$22bo$20b3o2...

That would be xq0_2702072 That implies that it's a period 0 spaceship (whatever that would be)--as it turns out, x0_2702072 is a perfectly valid apgcode A period 0 spaceship is a pattern that returns to its original state (up to a translation) whenever the generation number is a multiple of 0. So t...

I see, but which part contains the programming for the rule that the metacell will emulate? I understood this question to mean 'where is the rule table encoded in the metacell', and the answer is 'in the data tape, specifically the sparse section shortly after the start-of-tape (SOT) marker': Scree...

I have ran transfer.py on all unsynthesized xs20 still lives to get a list of usable components. https://gist.githubusercontent.com/testitem/a99b6c27f6dfa66350555f75cd3ca933/raw/9e237e3ba4fd9f04f88a6b40d7390e48d09b7845/components.sjk It solves at least five still lives: xs17_25a88bdzx252>25 -3/-14 ...

This non-component found by Alex Greason using his version of collisrc.py technically reduces 3 tails to 14G That's the only time I've seen a synthesis which begins as an incremental synthesis and then turns into a soup-based synthesis. (Usually, syntheses work the other way around.) For posterity,...

How do we know that there's not a soliton-like spaceship such that any collision between solitons has the same effect as if they passed straight through each other?

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. In the case of slmake, there are 6 strategies (if I remember corre...

I've submitted most of the syntheses from this thread to Catagolue, and also ran a depth-2 transfer.py search over the resulting Shinjuku database.

We should also add syntheses for the xs18s for which Shinjuku/Cata doesn't know any synthesis. They were completed in 2017, right? The wiki says they were all completed by November 2014 in this thread , though I've also heard that some of these syntheses were actually invalid to begin with. At some...

Conway is the Counselor to the President of the United States, which makes Conway's Game of Life of inherent interest to Donald Trump.

That's Snowflakes, right? I had to restore the census after DefinitelyAlphanumeric deleted it, and the haul count was reset.

The first one is false, the latter true. Is there a better way, for doing so? It's relatively straightforward like so (by the way, this assumes the pattern consists only of disjoint gliders): import lifelib lt = lifelib.load_rules('b3s23').lifetree(n_layers=1) x = lt.pattern('''x = 16, y = 13, rule...

Are all non-still-life periodic objects with populations 16 and under also known to be synthesizable with 16 gliders or less? I don't believe that the space of 16-cell patterns has been exhaustively searched. (Indeed, what's the current status? Paul Callahan searched all 10-cell patterns a long tim...
