I posted an adapted version of apgsearch for 22da, apgsearch-hex-22da , in the Scripts forum. It's not particularly complete, e.g. doesn't save sample soup id's in progress file and common objects list only has two objects, but it works and I think has some components which might be of interest. Fir...

How well would the apgsearch method work on a rule like sansdomino_s13? My impression is that it would work really well after some adaptation. There are several places where semi-totalistic rules and rule notation are assumed. In particular, the auxillary rules and various tests that check which ru...

Is there an easy way to rotate clockwise/counterclockwise a cell array? In a regular square neighborhood rule, not hexagonal? putcells(), transform(), and parse() all have optional transform parameters. Sample usage -- draw something in a new universe between (0,0) and (99,99) before you run it: im...

Similar to the p4 moon eater in reactions.rle, two p8 sparklers can operate as a moon eater: x = 37, y = 24, rule = B2/S0 obo$b3o$3o$bo3bo$4b3o$3b2ob2o$4b4o$5b2o2bo2$7bobo$12bo7bo7bo7bo$11bo7b o7bo7bo$11bo7bo7bo7bo$12bo7bo7bo7bo$7bobo2$5b2o2bo$4b4o$3b2ob2o$4b3o$b o3bo$3o$b3o$obo!

Here is apgsearch-blonksoup.py The main difference with the original apgsearch is that the 16x16 random soup is replaced with a random field of blocks and blinkers, and a single glider. This version creates a relatively sparse distribution of objects, placing up to 25 objects on a diagonal rectangle...

This thread is to discuss variations of apgsearch which go beyond incremental improvements and minor changes to the program. First off, a few ideas: I also have been searching for glider reactions with a collection of common ash objects. There are a lot of reactions like this (not just switch engine...

I put this item on the To Do list: # TODO: extend the common-objects list further with top 1800 objects from # http://wwwhomes.uni-bielefeld.de/achim/ash-pattern.txt I'm curious about what people think about radically extending the common-objects list in this way. I don't think this will make any n...

Similar to the moon eater, a moon can pull a pair of checkers in the right phase, but they are moved 4 cells in place of 2. This means p4 back rakes which move at c can be converted into spaceships, e.g. x = 39, y = 18, rule = B2/S0 33bo$32bobo$32bo2bo$32bobo2bo$35bobo$34b2o$bo$o10bo7bo7bo9bo$10bo7b...

But I have no idea if they are of any interest. They are to me!! Thanks. Glad to hear it. I've read through your switch engine thread and saw the patterns creating a switch engine from a glider collision with a small number of ash objects. Do you have an archive of this kind of reaction? This was w...

I don't know of any, but I have often thought it would be great to have a purpose built program/interface to help design rule tables. My general approach at the moment is to use golly to test a rule-table I'm working on. I have a collection of small patterns in a row with neighbourhoods of interest,...

Here's another p3 oscillator: xp3_6a889b8ozx33 Glider + Block + 2 Blinker -> 18P3.32 + junk x = 16, y = 10, rule = B3/S23 11bo$4b3o4bo$11bo$2bo$bobo3b3o3b3o$3obo$2obobo5bo$ob2obo5bo$3ob2o5bo$ 2o!

I haven't really been able to get a good idea of your sawtooth project yet, though I can see the parts coming together. I hope you're able to make some good progress on theproblematic details soon. In 22darealDLA, I still find myself surprised that there is no unbounded growth of the state 2 cells. ...

This is an interesting puffer which leaves behind a stream of forward c/2 ships. It has been extracted from a chaotic explosion and cleaned up. x = 217, y = 219, rule = B268S3456F01356K268L0345 9$33.2A2$32.A2.A2$31.AB2.BA10.2A$31.B4.B$30.A2B2.2BA8.A2.A$31.B4.B$ 31.AB2.BA8.AB2.BA$45.B4.B$32.A2.A8.A2B...

Here is the v3 list with #719 omitted. The other list is completely redundant, as you pointed out. Thanks for putting this together. Only a few unsolved 18-bitters -- #102 and #103 -- have shown up in my soup searches so far, but other people may have different results. On any computer that has bee...

On closer inspection the pattern I showed was not a particularly good example. Here is a synthesis of a different ship: ... A very good start! Including your new period 23 gun, my gun collection for this rule now contains 32 guns which fire a variety of ships. Unfortunately this little ship: x = 3,...

Apologies, you are correct in explaining the difference. I think I was confused by the similarity to another rule family I explored. Can you confirm: do the three counts (C/B/S) only count live cells in the neighbourhood? And then the question is which state is which? Would you post the rule table f...

Terminology for the types of cells / rules you mention was introduced in another thread, however I'm not sure if it ever caught on.

Congratulations on the find!

My own search at 2c/6 mentioned earlier only went as far as widths of 27 and 28 with bilateral symmetry. I'm still running the other searches at c/6 and c/7.

And here is a naturally occurring growing ship / wickstretcher(?) which I particularly like. The front end moves at c and the wick/fuse burns at c/2.

Thanks for the explanation. I hadn't realised how to use 'don't care' cells in wls until now. Edit: Here's a slightly smaller variation on the theme. I nearly always turn off the "Try ON cells if they have greater impact" option which seems to find smaller versions of extensible patterns earlier in ...

That is fantastic. Were you inspired by the Seeds version which seems to be quite different? If not, I'm very curious to know how you came up with the front end to support the wave.

I'd appreciate if someone did a spot check, but I believe I got the correspondence right. Nicely done! Yes, I checked every fiftieth still life (lin...
