Glider streams merger with repeat time p38:

Code: Select all

x = 67, y = 71, rule = B3/S23

And I need p37 :(
EDIT: on the other hand, it is probably sufficient for my needs anyway ;)

That's why I said finite. The two glider streams are able to pull three different objects.

Well, the block pull is obvious since the spacing is 10hd, and there's a really common glide-reflective block + beehive reaction. But what's the tagalong?

This seems like a fairly tricky gun to build outside of the "extendedlife" rule, by the way. Is there even a known mechanism to insert a final glider from just one side into a pseudo p26 glider stream? All the methods I know need support from both sides -- an LWSS on one side and a glider on the other, for example.

I seem to recall there's probably a painful way to manage the trick, starting with p390 guns, and gradually nudging gliders into the stream with p30 oscillators -- or was it pentadecathlons? Anyway, is there a better way in B3/S23 to build two p26 glider streams ten lanes apart from each other? It's possible to build this kind of protected gun in LifeHistory using just the gray cells as a barrier... but only if the basic gun works in plain old Life.

If anyone finds a suitable 13c/32 spaceship with period 64, here's a puffer back-end that can be attached:

Both phases that are dependent on supporting sparks are shown. (I wonder if this pattern produces sparks which can support a second copy for one half of a cycle...

Here is an interesting wick where a pi travels down a line of boats (supported by blocks; I'm not sure if a block-less version exists where the exhaust does not destroy the boats or kill the pi's) at 2c/5 and pulling a block behind it!

And, surprizingly, it worked! It became a p120 puffer!

EDIT: I have loads (literally thousands) of 20x20 soups like this which produce unusual objects, generated by Andrzej Okrasinski's Life Screensaver. I usually only post ones for oscillators or unusually large objects on here, but if anyone would find the rest of them useful (e.g. for finding glider syntheses of unusual but natural objects) I could upload them somewhere. I reckon people on here will have more use for them than I do.

Sure! It'd potentially help with some of the peskier syntheses. Put it like a ZIP file or something.

I think it's unlikely. You could try to chain multiple copies together to form a fuse, but unfortunately, the beehive forms in a way that it attacks the next block in the chain before it's fully formed.

In many cases, such objects come up in ways that are too difficult to use (e.g. the easiest way is to construct the methuselah, let it run for hundreds of generations, then use dozens of gliders to pick off most of the ash to recover the one jewel). However, in a few other cases, such spontaneous objects may suggest viable predecessors. Sometimes, this drastically reducing the cost of objects (e.g. Dave Buckingham, while building all the still-lifes up to 14 bits, had one he called "The Still Life From Hell", as it took 33 gliders - which was later reduced to 14, when the main part of it popped up from random muck). Sometimes, this provides a synthesis path for objects for which no previous synthesis was known (e.g. Fore and Back). Even if 90% of such object predecessors are impractical, the few others make it worthwhile to keep track of them, just in case.

Re: Thread For Your Accidental Discoveries

I've found a bit of a problem with just uploading the .lif files. There's no nice way of searching for an individual pattern, the only possibility would be opening files at random and hoping its a) something interesting and b) the file actually leads to a possible synthesis.

However, I think the way the random seed generation thingy works means that if I was to upload parts of the LifeSS software (because Andrzej Okrasinski's website disappeared when Geocities closed) along with the big table of objects and the last seed which generated them, it would allow others to generate the soups which produced the objects for themselves. (and that would save having to upload ~70Mb of confusingly named .lif files too).

Also, I'm not sure how well (if at all) the software will work on things that aren't Windows.

Here's a link to a .zip folder with some of the tools packaged with the LifeScreenSaver software, and a table of all objects (and pseudo-still lifes) along with the last seed that generated them; http://www.mediafire.com/download/l6bcg ... LifeSS.zip

How to find the seed which generated the object:
1. Open 'PrjDef.exe'. Draw the pattern you're after into the check-boxes thing. Then press 'Oblicz', which will convert the object into a hexadecimal code thing (It doesn't matter which orientation the object is in, the program magically returns the same code for it). Copy the code to the clipboard.

2. Search for the code thing in each ofthe .txt files (use notepad with Ctrl-F or whatever). If the object has occurred naturally you will find something like the following:

Code: Select all

1129
shape = "00c000a0001000080004000200010003" <-- the code you searched for
size  = 11
type  = STABLE
count = 1
lseed = 91675117   <-- This is the last random seed that produced the object

......##
.....#.#
....#...
...#....
..#.....
.#......
#.......
##......
(If it's a common-ish object then there's a chance it'll show up in more than one of the text files. This just means you get three separate soups, all of which should lead to the object in different ways. Lucky you.)

3. Copy the number 'lseed'.

4. Open 'rblife.exe'. Then go to 'Action > Random...'. Set size to 20 and random seed to the number copied from the text file before. Density will be the last 2 digits of the textfile you found the object in (i.e. for lf02050.txt, set density to 50).

5. This should generate a soup that creates the desired object. The program's 'save' command should allow exporting into a file format which can be run in Golly or whatever. then find glider syntheses for the object (I wish I knew how to do this, it looks like a steep learning curve though).

This seems to be the best way - an identifying number (e.g. seed) and software that can convert it into a pattern.

Fortunately for me, I have windows on both my desktop and laptop computers. Plus other operating systems usually have ways of running Windows programs in a sandbox, one way or other, with varying degrees of satisfaction.

Thanks! I scanned through the included file H02015.txt, and found about 3 dozen or so patterns that, when I look at them, I couldn't think of how to synthesize them. I also noticed a few that I had struggled with in the past to synthesize (plus a few that I spent a lot of time synthesizing just in recent weeks - plus one "on my short list" that I tried to synthesize a couple of days ago, came fairly close, but failed).

Incredible serendipity: I drew a random squiggle on the plane to generate a constellation of oscillators and still lives, and the shape quickly formed a hook-with-claw, before destroying it after a few generations:

Here is the first gem dredged from the random screensaver output. I had tried to build on several occasions, and found a solution that was fairly close a few weeks back, but was unable to make it work. But now, it's easy, by imitating nature:

x = 127, y = 36, rule = B3/S23

o!
I've also since found one other synthesis that has been drastically improved by using a "natural" reaction from the screen saver output. I've converted the text files into a format more suitable for comparison with my own database lists; I'll try to look into them more closely when I have some more time. I'm sure quite a few other gems will show up. There are many objects in the list that have syntheses that are quite expensive. There are also many for which I haven't seen any syntheses at all (and there doesn't seem any obvious way to create any).

The LifeWiki name for that is claw-with-tail, and it's a 4-glider synthesis. This would be more suitable for the useless discoveries thread I started.
