What is the convoy with least constant breadth that can support an arbitrary long *WSS?

Cheers,

The search that found this started with "wildcard" input columns to LLSSS, where I've fixed the center 3 columns but then the next 3 columns can be any values they want. When run wide enough it finds this cycle somewhere "downstream" (f2b) and when run one less wide it terminates. I infer that if there is a thinner repeating section it is both everywhere-thickish (each slice is at least 4 interesting columns) and moreover findable f2b only from such thickish slices. I could not complete an analogous search but with 4 wildcard columns due to memory limits.

[dvgrn]

Just a plain error in the search setup!This works better (edit: corrected another copy/paste error).

Are there maybe a couple more errors to correct? The last two RLEs, the mixed grain end piece and the ant front, don't quite seem to be self-sustaining. (?)

[HartmutHolzwart]

These are all old partials, put there in the hope to give Keith some more ideas how to continue his searches. Maybe he has the right idea and resources to complete them. I just had a few minutes to post, sorry!

I discovered this reaction by accident when trying to reduce the crotchet synthesis.
Is this boat-pulling reaction known?

Now that I've sketched diagonal symmetries for LLSSS, I'm starting to look at what it enables. One thing is to try to produce a 2c/8d glide-symmetric odd front for a barber pole. It reduced to c/4d quickly enough, but I was not immediately able to solve it as c/4d. A possible beginning partial might look something like:

Code: Select all

Another cool partial. I fear it‘s out of reach for WLS, but you only know if you try. Sometimes I‘m lucky.

Is the following 2c/9 orthogonal infinite puffer wave known? (Edit: hotdogPi found the small spark-supported component without the connecting blocks back on January 22, 2023.)

Code: Select all

x = 44, y = 5, rule = B3/S23:T44,0
4b3o8b3o8b3o8b3o$4b3o8b3o8b3o8b3o$o2bobobo2b2o2bobobo2b2o2bobobo2b2o2b

It can be stabilized by domino sparks in two different ways:

Code: Select all

x = 44, y = 5, rule = B3/S23
4b3o8b3o8b3o8b3o$4b3o8b3o8b3o8b3o3bo$o2bobobo2b2o2bobobo2b2o2bobobo2b

4bo5bo!

A sufficient 2c/9 orthogonal domino sparker would then give a finite puffer. The interaction is weak enough that it might be a good starting point for a direct LLSSS search.

I found this wave while testing a cylindrical hack of qfind. I tried a width-6 odd/even and got the following longest partial result:

I noticed that the first few rows were only loosely connected to the back, so I ran them on their own and discovered that they formed the infinite puffer wave.

Completely unrelated is this useless 2c/9 superstring-supported wave front end:

I want to point out that the new barberpole stretcher is an almost-phoenix growing object. That is, the percentage of cells which stay alive for more than one generation approaches zero.

This old phoenix puffer also has that property, but the barberpole stretcher is much better since it is closely connected.

Code: Select all

#C A period 48 phoenix puffer.
#C This produces a period 2 phoenix oscillator every 48 generations.
#C This growing object has the unusual property that the percentage of
#C live cells which stay alive for more than one generation approaches
#C zero.

I sort of accidentally discovered this other cool puffer based on the same engine.[edit:] It was probably going to be discovered anyway

[amling]

A sufficient 2c/9 orthogonal domino sparker would then give a finite puffer. The interaction is weak enough that it might be a good starting point for a direct LLSSS search.

Uh, I think a 2c/9 ship with a domino spark might be a bit of a tall order. That 9 seems impossibly big, but I suppose it will not hurt to set up a few quick searches...

My best guesses for search types are (a) s2s recentering which looks like it's not going to get anywhere w/in acceptable memory and (b) an immediate f2b turn which looks like it will at least get past the critical point on the turn, meaning it has become "just" an f2b search. More details later once these reach the front of the project queue and I can run them at real size.

So far (just a few very small test searches) the best of (a) is:

Code: Select all

|  ....**... |  ...***... |  ......*.. |  ......... |  ......... | .........  | .........  | .........  | .........  |
|  ......... |  ...*.*... |  ...*.*... |  ......... |  ......... | .........  | .........  | .........  | .........  |

(no RLE since it's so short a single gen is meaningless).

So far the best of (b) is:

That 9 seems impossibly big, but I suppose it will not hurt to set up a few quick searches...

That's basically my thinking. Maybe we'll get lucky and the solution is small enough to find with current methods. It's still probably quite a long shot.

Here's something that I think LLSSS might be well suited for that is slightly less of a long shot: find a p7 3c/7 rake based on this idea.

I've added it to my queue/notes.

My best guesses are same two techniques (fixed board f2b turn and s2s recentering). In preliminary searching f2b turn didn't look too hot and s2s recentering looked maybe okay, e.g.

Is there a corresponding c4d barberpole eater?

I was not able to produce one. All four big successes with the technique that produced the stretcher (namely doing a high period search and looking for a slice that is a division of it, 4c/8 -> 2c/4, 2c/8d -> c/4d, etc.) have been b2f-like:

*) Quartermax. No real back found. The back I did find was found via full 4c/8 search, no period reduction involved.
*) Blocks-on-parallel. No back at all found.
*) Blocks-on-OWSS. The back I found I drew in golly by hand and guesswork before the period reduction searches got anywhere.
*) 2c/8d barberpole. No back at all found.

In all four cases a period reduction result would be interesting and I gave it somewhere between a modest effort and a severe one. My best theory is it needs a lot of luck in a little space and b2f searches provide more choices to make per unit space (which is why they're bushier and worse than f2b for bigger searches).

LLSSS now allows wildcard trickery in input pictures, in some cases, in some places. This allows me to do something like make LLSSS "guess" an odd front corner of a fixed thickness for a 2c/5 perpendicular stripes greyship and continue them all s2s. E.g.:

Code: Select all

|  LLLLL12RRRRR |  LLLLL12RRRRR |  LLLLL12RRRRR | LLLLL12RRRRR  | LLLLL12RRRRR  |
|  .....aa*.*.* |  .....bb*.*.* |  .....cc*.*.* | .....dd.*.*.  | .....ee.*.*.  |
|  .....WW*.*.* |  .....WW*.*.* |  .....WW*.*.* | .....WW.*.*.  | .....WW.*.*.  |
|  .....aa*.*.* |  .....bb*.*.* |  .....cc*.*.* | .....dd.*.*.  | .....ee.*.*.  |

I had configured it to wildcard a-e but make them match up/down in a column and wildcard W normally. L, 1, 2, and R mark the "roots" for the recentering search.

I ran a bunch of similar searches (even/odd for various thicknesses, although odd is expensive so not very thick for that). I then took the most viable-looking front corners (i.e. the few that had survived the longest in the wildcard search) and searched them directly. Combined with ends that will notice the final rows being legal odd or even symmetry this could have found a double-symmetric level front, but sadly it did not work out.

The longest partials for each of the four best-looking initial corners I had chosen were:

This c/4d wave with a repeatable middle dropped out of a completely unrelated search. I'm not sure I want to take the time to try to chase down two more edges and 4 distinct corners to make the agar ship:

In preliminary searching f2b turn didn't look too hot

Did you try symmetric searches, or just the asymmetric search? I assume symmetric searches would be more likely to succeed in a case like this just as they're more likely to find spaceships in general.

What search do you refer to? The completion of the 3c/7o rake part?

I'm referring to the 3c/7 rake search. I think a symmetric central part, as in my original partial result, is more likely to be found at a lower width than an asymmetric solution.
