This is what I was essentially trying to suggest to search.dvgrn wrote:If something like that existed, it would have to move at the same speed as the knightship to keep doing its suppression work, and so it would be a very good candidate knightship on its own.Gamedziner wrote:Is there any "small" (less than 1000 cells) means by which those two cells could be prevented from appearing, thus allowing a sort of flotilla knightship?
It might work to start a new search for a "support" ship that suppresses those two cells in the almostknightship, and see if any solutions happen to come up for the different possible searchable shapes. I would expect that one or more people have already tried something along those lines, but I don't know for sure.

Re: Spaceship Discussion Thread
Kinda crazy question: is it possible to make a smaller helix for the toofast 13,1c/31 to with blinker fuses instead of just xwsss?
Ex) back G + suppressed blinker fuse => another G at the front
Ex) back G + suppressed blinker fuse => another G at the front

Re: Spaceship Discussion Thread
It would be a higher multiplier almost certainly, but could have fewer overall spaceships per cycle. Not sure how easy it would be to synthesize but I don't know, there's already a mountain of synthesis problems with all the HWSS in the current best helix.
Physics: sophistication from simplicity.

Re: Spaceship Discussion Thread
Although I'm not experienced with building helices to be specific periods, I think I have to agree with the above: to actually gain over the 11c/24 burn reaction, the amount of time spent burning must be very long relative to the lengths of the fuses.
However, I do believe there is room for improvement in helix design. By starting with a somewhat odd LWSSonMWSS flotilla I was able to find a helix edge component in a few different variations (low *WSS options on top, smaller area options below. Leftmost is for comparison):
I don't know if it's known, but I figure there's probably some other useful cornerturn reactions out there we don't know about yet. If it produced the same glider four gens earlier it would allow for a 4x 17c/45 helix, but since it doesn't, the maximum speed for a period 180 helix is only 3c/7...
EDIT: Interestingly, the Coe ship by itself can function as a helix edge. Not only that, but the glider ends up displaced over 20 cells at nearly lightspeed. Unfortunately the big plume created from the reaction prevents it from being all that useful:

Re: Spaceship Discussion Thread
Here's a partial for a c/6 ship, found fairly quickly with knightt:
What's interesting about this one is that the back can likely be completed symmetricallyobserve the behavior around the cells in white. I'm not sure how to get any of our existing spaceship searchers to continue it as a symmetrical search while the front remains asymmetric, though.
This would be relevant to complete because of the relatively loose connections in the asymmetric front. It means that the full ship, if it turns out to be smallish, will be a decent candidate for glider synthesis.

Re: Spaceship Discussion Thread
The "best" c/9 partials that I'm aware of are the ones posted on page 2 of this thread (evensymmetric partials here and oddsymmetric partials here). It's hard to say if these are "good" partials. None of them are very long, and they generally are all "strongly connected" (only the first evenwidth partial seems to have a "loosely connected" front end). You could try extending these with zfind as explained here.muzik wrote:Are there any good c/9 partials?

Maybe some sort of engineerable reaction could be in the making?

People have talked about this a lot over the years, but all of these ships/partials seem to be beehives/loaves followed by "space junk". I haven't seen anyone actually propose how to find the seemingly random back ends (besides using the tools we already have for lowperiod spaceship searches).muzik wrote:I find it kind of interesting that a lot of highperiod ships involve pushing either a loaf or a beehive.

I think this is essentially what Tim Coe did to find the snail, but I could be misunderstanding the explanation. (Edit: I was wrong)muzik wrote:Are there any search programs that search exclusively for the back ends of spaceships, so that we could potentially link them up to front ends?
gfind has a reverse option that searches for spaceships from the back, but in Life it is much slower than the forward search, so I'm not sure if it would help at all. I think you would essentially need to run the forward and reverse searches at the same time, and periodically check to see if any of the reverse partials could complete any of the forward partials. This adds a lot of extra complexity to the program and might not speed it up very much. I think it would be better (and easier) to take the current forward search programs and find ways to distribute them among multiple CPUs and multiple computers.

Re: Spaceship Discussion Thread
Well, what I was mainly thinking of doing is searching for relatively long back partials, and attaching them to the backs of known front ends. Namely the ones that have been posted in this forum
Bored of using the Moore neighbourhood for everything? Introducing the Range2 von Neumann isotropic nontotalistic rulespace!
Re: Spaceship Discussion Thread
The problem is, most of the partials posted on the forums are at widths where no spaceships exist. Thus, to complete the spaceship the back partials would have to be even wider than the front partials. Since reverse searches are so slow, it would actually be faster to start with your front partial result and try to extend it at a larger width.muzik wrote:Well, what I was mainly thinking of doing is searching for relatively long back partials, and attaching them to the backs of known front ends. Namely the ones that have been posted in this forum

Re: Spaceship Discussion Thread
I guess that makes sense.
I mentioned creating a list of partials of some sort earlier in the thread. How about it?
Earlier I found a c/26 glidesymmetric reaction of sorts. I doubt this would be usable to create a spaceship though.

Re: Spaceship Discussion Thread
Kazyan and Sokwe,
A while back I posted some of the first ships that came out of a c/6 odd symmetric search started at width 19 and continued at width 17. This search continued and finally completed and found more ships. I looked through the output file and saw a matching several rows with Sokwe's continuation of Kazyan's asymmetric front end.
For general interest here is the full set of c/6 ships the above mentioned search produced:
Sokwe,
You asked if I could provide more precision on when the variety of small c/4 ships were found. My records and memory are scattered and sometime between last December and March is a realistic approximation.
The snail was found by a standard search from the front. I have tried some searches from the back and they just don't work well.
Have a happy day,
Tim Coe

You asked if I could provide more precision on when the variety of small c/4 ships were found. My records and memory are scattered and sometime between last December and March is a realistic approximation.
The snail was found by a standard search from the front. I have tried some searches from the back and they just don't work well.
Have a happy day,

Re: Spaceship Discussion Thread
That's amazingly convenient. This is now the thinnest known c/6 orthogonal spaceship, although a width 11 or 12 ship probably exists.moebius wrote:I looked through the output file and saw a matching several rows with Sokwe's continuation of Kazyan's asymmetric front end.
I ran the c/9 width15 gutter search with zfind, since I couldn't find any indication that it had been done before. Here are the longest partial results:muzik wrote:Are there any good c/9 partials?

Re: Spaceship Discussion Thread
So how would one actually find the spaceships then? Since they're called "partials" do you simply find a rear end for them all, try to attach some random stuff to the back, or (most likely) run a promising front end through searches?
Bored of using the Moore neighbourhood for everything? Introducing the Range2 von Neumann isotropic nontotalistic rulespace!
Re: Spaceship Discussion Thread
Ususally, it's the last one: use a known partial result as the starting point of a gfind/zfind/knight2/WLS/JLS search.muzik wrote:So how would one actually find the spaceships then?

I described how to extend partial results with zfind here. This is closely related to extending partial results in gfind, which Paul Tooke describes here (row ordering is the same as in zfind). I know that knight2 can also extend partial results, but I don't know how to input the initial rows.

Re: Spaceship Discussion Thread
Whenever I get round to trying to figure out how to work them, what would be a good usable partial to test if it's working?

Re: Spaceship Discussion Thread
It doesn't matter, as long as you can tell that the output looks right. In my post on extending partials with zfind, I extended the front end of the dragon as an example. I could quickly tell that I had input the rows correctly, because the output partials had the same front end as the dragon. If you mess up, it usually causes the search to terminate almost immediately, with the longest partial being 2 or 3 rows.muzik wrote:Whenever I get round to trying to figure out how to work them, what would be a good usable partial to test if it's working?
Edit:
I tried to extend this partial at width 18 using zfind, but it didn't find a ship. Here are the longest partials:muzik wrote:Here's a c/8 partial from the other thread
