c/7 orthogonal spaceships

For discussion of specific patterns or specific families of patterns, both newly-discovered and well-known.

c/7 orthogonal spaceships

Now with several new versions of search programs out and PCs still getting more powerful, it might be time to revisit this topic:

Are there any serious search results out there? Promising intermediate results? Ideas?

Re: c/7 orthogonal spaceships

The best c/7 partial pattern I have is this:
`x = 40, y = 1711bo\$10bobbo12bo\$5b3obbo14bobo11bo\$10bo10boobb3oboo3bo4bo\$boo11boboobbo7b4o3b4o\$obbo6bobob8o4boobobobobo\$boobboo3bo28bo\$5boo4b12obbo8boobo\$\$5boo4b12obbo8boobo\$boobboo3bo28bo\$obbo6bobob8o4boobobobobo\$boo11boboobbo7b4o3b4o\$10bo10boobb3oboo3bo4bo\$5b3obbo14bobo11bo\$10bobbo12bo\$11bo!`

There may certainly be longer partial patterns for this width.

Paul Tooke may have some better partial patterns and has likely put some serious search time in on this problem.

My only idea is to take a partial pattern with a small width, like the partial I posted near the front where the blinkers are, and try to extend the pattern in different directions. I have not had any success with this.

Edit:
Another partial:
`x = 35, y = 2731bo\$31bo\$28bobboo\$28bo\$27b3o\$26bo7bo\$24bo4bo\$18bo4bo3bo\$7bo8bobobboo3boo\$boo3bobb4obo3bobboobo\$obboboobo5bobo4bobo\$boo3bobob3obo3bobbo\$17b4o\$\$17b4o\$boo3bobob3obo3bobbo\$obboboobo5bobo4bobo\$boo3bobb4obo3bobboobo\$7bo8bobobboo3boo\$18bo4bo3bo\$24bo4bo\$26bo7bo\$27b3o\$28bo\$28bobboo\$31bo\$31bo!`

According to my records that is incorrect on both counts. The only searches I did for c/7 orthogonal spaceships were a few narrow width gfind searches back in 2000. That was before I had added the state-saving code, so I have no partial patterns.

I do remember at one time trying searches with the search tree initialized with partial patterns consisting of the beehive-push from the Dragon (It can happen at c/N for N>=6). This is similar to the front end of Hartmut's partial result. Unfortunately, I don't appear to have retained any records of the seaches or any partial patterns.

I believe that Hartmut is right. Technology has moved on and it may be that there are things to be found by someone who is prepared to devote a good chunk of CPU time to the effort.

Re: c/7 orthogonal spaceships

Paul,
Thanks for the input. I knew you had some quality 3c/7 partials from your long searches, so I had assumed similar for c/7.

I found a c/7 spaceship!!! And it's small, min pop 20 cells.

Re: c/7 orthogonal spaceships

That is absolutely amazing! This has to be glider constructable. I'm freakin' out over here!

Edit: I honestly thought you were joking. I looked at the RLE and thought, "Ha Ha, I wonder what that really is." Boy, was I surprised!

Edit 2: I honestly thought you were joshing me. Eh? Eh?

I'll probably leave it to someone else to build an explicit gun.

Re: c/7 orthogonal spaceships

Hoooooooly shit, that's awesome.

Shows that there are probably other similar surprizes still lurking around to be found…

I find interesting how the two halves interact only marginally, seems like there could be potential for a further grammar of components. E.g. two copies of the lower portion make up a symmetric 16-cell spaceship if birth from 4 diagonal neighbors is allowed…

And here is the 18-glider synthesis as a single pattern. I predict that someone will make a gun out of this within 18 hours:

Re: c/7 orthogonal spaceships

I should add that I found this with WLS. I found the smaller half a while ago, but couldn't finish a spaceship with it. This thread encouraged me to keep looking. In my searches WLS found the second half and completed the ship with the first half I had found earlier. It's entirely possible that there are other ships which use these parts. I was very surprised how small this ship was, and had to recheck several times that I had been searching with the right settings.
Thanks for coming up with a glider synthesis so quickly. It's not every ship that has a synthesis.

Re: c/7 orthogonal spaceships

In the realm of boring synthesis reductions, this ship takes no more than 11 gliders:
`x = 26, y = 37, rule = B3/S2323bobo\$23b2o\$24bo\$10bo\$2bo5bobo\$obo6b2o\$b2o3\$6bo\$4bobo\$5b2o4\$18bo\$16b3o\$15bo\$6bo9b3o\$6b2o10bo\$5bobo8\$12b2o\$11bobo\$13bo2\$23bo\$22b2o\$5b3o14bobo\$7bo\$6bo!`

It is very likely that the bottom part can be synthesized more directly (with 3 or 4 gliders).

Re: c/7 orthogonal spaceships

Congratulations to a really awesome c/7 ship, I would never believe that such a small object could avoid being found in myriads random soup/random agar searches performed so far. I had to check the rule twice before I believed that it's really running in the standard GoL rule...
Congratulations!

You can say that again! Hardly *any* spaceships have syntheses, let alone such straightforward ones. This will fairly quickly require an update the whole (1,0)c/7 line in Jason Summer's table of spaceship velocities. Except maybe the "wickstretcher" cell -- anyone know if there are any likely wick candidates at c/7?

"Versatile puffer" will take a while, too, I suppose. But from the look of the two parts of that c/7 ship, with interaction in only one tick out of the seven, it certainly seems as if new combinations and tagalongs with usable sparks might appear in fairly short order.

Edit: I looked again, and it's not quite that simple a connection; there's some interaction between the halves in two successive ticks. Still seems like a good bet that there are more variants out there!

-- Do you have a name yet for these wonderful new Life forms? I'm thinking of them as "loafers" until you come up with something official.

I have seen the smaller part of this spaceship in my own searches, and it has other simple connections that might lead to new ships:
`x = 37, y = 8, rule = B3/S232o31b2o\$b2o14b3o13b4o2\$3b3o11b3o11b3o\$4b2o12b2o12b2o\$b2obo10b2obo10b2obo\$bo2bo10bo2bo10bo2bo\$2b2o12b2o12b2o!`

On this note, I think I have eliminated the possibility of a height 8 c/7 orthogonal spaceship (I'd like independent confirmation before I say anything definite), but starting with one of the parts of this new spaceship may be a quick way to find something taller. Has anyone ruled out the possibility of a width 9 spaceship of this speed?

Still, we might be as well off trying to find new c/6 orthogonal spaceships, as we still don't have any puffers for that speed. A good starting point might be the following subpattern, which occurs in two of the known c/6 orthogonal spaceships:
`x = 10, y = 8, rule = B3/S232b2ob2o\$b4obo\$o6bo\$bo4bo\$6bo2bo\$4bo3bo\$8bo\$8bo!`

dvgrn wrote:anyone know if there are any likely wick candidates at c/7?

The only viable candidate I know of is this period-12 wick:
`x = 47, y = 7, rule = B3/S232bo5bo5bo5bo5bo5bo5bo5bo\$2o2bob2o4b2o2bob2o4b2o2bob2o4b2o2bob2o\$4o2b2ob2ob4o2b2ob2ob4o2b2ob2ob4o2b2ob2o2\$4o2b2ob2ob4o2b2ob2ob4o2b2ob2ob4o2b2ob2o\$2o2bob2o4b2o2bob2o4b2o2bob2o4b2o2bob2o\$2bo5bo5bo5bo5bo5bo5bo5bo!`

Unfortunately, we don't seem to be close to even finding a c/5 stretcher for this wick, much less a stationary stabilization for either end.

Re: c/7 orthogonal spaceships

Here's an 8-glider synthesis:
`x = 40, y = 37, rule = B3/S2338bo\$37bo\$37b3o2\$8bobo\$obo6b2o\$b2o6bo\$bo3\$4bobo\$5b2o\$5bo20bo\$24bobo\$25b2o2\$33bo\$33bobo\$33b2o6\$38bo\$37b2o\$37bobo8\$5b3o\$7bo\$6bo!`

This could still probably be worked down a little.

Re: c/7 orthogonal spaceships

Wow! The whole time we were still doing the soup search, I was waiting and waiting for a nonstandard small ship to show up naturally. But it's been there the whole time AND it is at a new velocity

Re: c/7 orthogonal spaceships

There are zillionplexes of 20-cell patterns, and most of them are going to occur naturally incredibly rarely. Besides, oscillators and slow spaceships will presumably have less of a chance of being detected than faster ones, due to lesser chances of survival. If soup searches DO turn up a non-standard spaceship eventually, I bet it would be faster than this one.

Sokwe wrote:Still, we might be as well off trying to find new c/6 orthogonal spaceships, as we still don't have any puffers for that speed.

From around p7-ish, 2c/6 is also a search option.

(Also I've said this before, but the fact that the four natural spaceships AND the switch engine are all glide-reflective makes me wonder how so few glide-reflective "artificial" ships have been sought yet.)

Re: c/7 orthogonal spaceships

I really like Dave Greene's name for this ship, "loafer", as it describes both its slow movement, and the fact that it pushes a loaf. @Velcrorex, what do you think?

The problem with such spaceships is they are limited to even periods greater than 2, so they quickly become difficult to search for. Since 4 is a reasonably small period, we have been able to find many glide symmetric c/2 orthogonal and c/4 diagonal ships. There have been a number of p6 c/3 glide symmetric ships using p3 supporting components, but beyond this, these are the only ships I know of where the glide symmetric component was found directly (first by Jason Summers, middle two by Nicolay Beluchenko, last by Josh Ball):

Why does the period matter though? I mean, if searching for these in particular, obviously you wouldn't just scour the whole search space and hope that any results had some extra symmetry, but set an obvious symmetry restriction in place to begin with. Thus standard spaceships should be found in a p2 search, etc.

A search for a glide symmetric spaceship of period 8 would be akin to a period-4 asymmetric search of the same width. From what I've seen, glide-symmetric ships do not seem to be too much thinner than a bilaterally-symmetric ship of the same speed.

... But if you add a glider in just the right place, you'll get a loafer. I've removed the glider in case anyone wants to try and figure it out -- but I'm afraid this kind of puzzle will never replace Sudoku. There's actually a big hint in the RLE, if you need one. Experimentation to find the various one-time-turner chains is a good idea, of course, but no fair using a script like pd-glider.py to find the answer for you. If you're going to do that, just try the pattern below instead:

EDIT: On another thread, 15 March 2013, I posted a unidirectional P1 slow salvo that creates this seed from a single block, then triggers it to build a loafer.
