### Re: Spaceships in Life-like cellular automata

I found that Rocknlol had found a c/5o earlier in B378/S2458 (here), so I took out a few entries made redundant by it.

Code: Select all

#C Rocknlol, 2020, B37/S245-B378/S24578
x = 14, y = 22, rule = B37/S245

They are:

Is there a backend for each side of this c/2o partial, possibly at a higher period?

It's not adjustable period, unfortunately. Moving the growing spaceship back doesn't change how long it takes to start growing again:

x = 16, y = 104, rule = B014/S12

I have also completed searches for c/5 orthogonal ships with odd and even symmetry of search width 8 in all B3 rules for which no spaceships are known (edit: that is, no spaceships of any type are known).

Would you like to help me surf the forums for already-known ships?

For example, I found in the B3/S345 thread several ships found by Josh Ball in 2013, including three unrepresented speeds in that rule. They are:

### Re: Spaceships in Life-like cellular automata

I found an old thread where the p5 knighships were first described. A user named eran911 found a (14,9)c/165 puffer in B368/S237 and wonders if it could be corderized. It is:

Code: Select all

3obo$5bobo2b2o$6b5o$6b2o!  A (4,2)c/44 wickstretcher in B36/S24567 is also mentioned, but a spaceship at that speed is unlikely to exist. I'm interested in seeing if we could find more like them. More recently, AforAmpere and I found a strong (2,1)c/7 partial in B36/S23. I was going to search the next width (margin 15) in LSSS, but got sidelined by other searches like the c/4o one I'm currently running in Seeds. Ikpx's source code specifies CGoL exactly once, but an attempt to adapt it to other rules ran into a roadblock. Details here.

Would you like to help me surf the forums for already-known ships?
I'm not sure what you've already looked through. The obvious thing is to search through each of the Life-like threads and check any posted spaceships against those in the database. The other thing to do is use the advanced search feature to find all posts by Josh Ball (Velcrorex) in the Other Cellular Automata board. Most of them will contain spaceships or discussions of spaceships. For example, this post by Josh Ball contains a 2c/5 ship not currently found in the database. There are probably a handful of additional spaceships in the Thread for Your Accidental Discoveries that Aren't in CGOL and Miscellaneous Discoveries in Other Cellular Automata.

Also, Glider 21575 was found by Nicolay Beluchenko, not Artem Dergachev. See this post.

Finally, here are three new 2c/4 spaceships:

It's the c/3 diagonal ship in seeds (B2/S) found in 2007. Run David Eppstein's database program with 21575 as the only parameter.

Impressive! Of all the rules I would think might have spaceships, B3457/S1238 would not be one of them.

Random patterns in that rule expand quickly with blotchy internal chaos. 2c/4 ships are often the easiest ships to find in such rules. That particular ship was the only thing found in my width-8 2c/4 sweep of B3 rules without any known ships.

I have been examining a few rules with B3456 and without any of S123. Such rules often favor odd-period ships with displacement 1. I recently found c/7 ships in B3456/S45 and B345678/S47. It turns out, they also have relatively small c/9 and c/11 ships:

I also took another look at B345678/S48, in which I failed to find a c/7 ship earlier (searched up to search-width 8). This rule has a reasonably-sized c/9 ship, which is the first known ship in this rule:

Edit: I completed searches for period-6 c/6 orthogonal ships with odd and even symmetry of search-width 7 for all rules in which no spaceships of any type are known. Unfortunately, I didn't find any ships.

### Re: Spaceships in Life-like cellular automata

Since no new spaceship discoveries have been announced in 17 days, I'll go ahead and post the updated version of the database.
new-gliders.db.txt
33 new spaceships
oscillators.db.txt
55 new oscillators
I'm still searching c/4o in B2/S and 3c/8o in B35/S236.

The top priority at current is apgsearching all the B3 rules that don't have any hauls yet. (See list.) Other areas of focus include finding knightships and exhaustive searching in the B2 rules. Anyone want to experiment with ikpx in OCA?

Also, if you find any errors or duplicates, report them here.

Code: Select all

x = 4, y = 3, rule = B3-q4z5y/S234k5j
2b2o$b2o$2o!

LaundryPizza03 at Wikipedia

The latest edition of new-gliders.db.txt and oscillators.db.txt have 31150 spaceships and 1205 oscillators from outer-totalistic rules. You are invited to help!

I've noticed that four of the eight known p5 knightships (B3678/S34678, B3/S1346, B3/S0346, and B357/S346) are in rules of the form B3xx/S[01]346yy, so I have chosen to focus there.

It's over 8 times as long as it is wide.

EDIT: Partial in B3/S346 that is about 3.42 times as long as it is wide. This rule isn't as promising as this one or Virus, but it can likely be found with LSSS.

### Re: Spaceships in Life-like cellular automata

Found an old post from 2010 with more candidate p5 knightship partials. It may be a good idea to revive interest in afind and ikpx. I found that the rule can easily be changed in ikpx, but I have had difficulties actually searching with the program.

The partials, found by Matthias Merzenich, are as follows:

For example, other than B36/S235 itself, I found the following partial: Code: Select all x = 29, y = 9, rule = B36/S0235 2bo24b2o$b2o16bo4b3obo$4o9b2ob3obob2ob2obo$4b2o3b7o3bo2b3o2b2o$2bo4bo 2b3obob2o5bo4bo$4b2o6bo2bo3bob5o$9bobo2bo4bobo2b4o$15bo2b2obo5bo$28bo!  An exhaustive search in 2013 using Paul Tooke's mod for gfind found that the p5 knighship in B3578/S235[8] is the only one up to width 10. No other general bounds are known. Maybe try exhaustively searching the B3 rules up to some higher width? Code: Select all x = 4, y = 3, rule = B3-q4z5y/S234k5j 2b2o$b2o\$2o!

Now I really want ntafind. Is it available anywhere or is it the "no-one-bothered-to-modify-it" case?
