18-bit SL Syntheses (100% Complete!)

[dvgrn]

From what I've seen, Buckingham's criterion seems to fit best for "natural" objects, like those that fall out of apgsearch. For those that don't, then yes, a higher-order polynomial would fit better. I've said before that I would like to run a statistics package on the 16-bit SLs, and now the 17-bit SLs, now that they're finished.

It will also be interesting to get some statistics on the things falling out of apgsearch. For instance, what proportion of all N-bit objects are "natural"? -- and how exactly do we want to define "natural", anyway? As the number of surveyed soups increases, the number of objects found creeps up very slowly but very steadily, probably according to the logarithmic power rule that showed up so nicely in Achim Flammenkamp's graph.

Some of the new objects that are showing up are pretty "unnatural", by any reasonable definition -- they'll show up from random initial conditions in less than one out of a billion soups, let's say.

Two or more occurrences of the same object in a billion soups might be fairly good evidence of "naturalness", I suppose. But it would be good to have some better way to disqualify objects that were present in the initial configuration, plus or minus some fading junk. Technically there's no reason why a Garden of Eden object might not appear in an apgsearch search...!

It still seems to me as if an obvious way to solve that problem would be to randomly construct initial conditions that are guaranteed to be glider-constructible -- piles of gliders and *WSSes all aimed at a 16x16 space containing N scattered ash objects, let's say. If an 18-bit object dropped out of a search like that, you'd instantly have a guaranteed glider construction.

-- But I suppose this is all a bit of a tangent on this thread, even if I do try to patch it up by mentioning 18-bitters. My apologies... nothing to see here, move along!

...and how exactly do we want to define "natural", anyway?

I was thinking along the lines of something that comes out of a soup. Now that I think about it, the term "natural" would be better suited to individual syntheses rather than objects. I would consider syntheses that come out of a situation in a soup (like #103) to be more natural than syntheses that use a whole bunch of modifications (like #173).

Can we get a list of those still lifes whose solutions are based on unsolved 18-bitters? That way I know which 18-bit still lifes I can use as a starting point for a complete synthest.

Here is a potential path to #729, but I haven't yet worked out the details:

None of them are currently dependent on unsolved 18-bitters. Or are you talking about 18-bitters formerly on the list?

I'm talking about 18-cell still lifes that are unsolved, but still not on the list. For example, the following 18-cell still life is clearly equivalent to #757:

Code: Select all

oo.......

.oo.o....

Niemiec would probably have such a list. (I know he did for the 16-bitters, and possibly for the 17-bitters.)

This method might also possibly be used for #257, #745, and #750, but I don't think the necessary starting still lifes are known.

I'm wondering what will be the last unsolved 18-bitter. I think #582 looks exceptionally difficult. #278, #675, and #755 also look tricky to me.

As for the question of last still life, I don't think it will be #757; that would use a variation of the component Niemiec used for Silver's P5 w/cis hook w/tail. I personally think #757 is more likely to be such.

In fact, at least TWO other ways are possible for #142; one is more like yours, while the other is a bit different, but still similar

Yes, thanks! I knew there must be some way to do it, but I couldn't find it.

Here's #163 from a 17-bit still life:
