Drat; nice to find it arising naturally from soup, though.

It consists of a pre-honey farm, two blinkers, a block, a beehive, a shape on the top that resembles a beehive right next to a theta spark, a shape on the left that generates a spark and an unimportant loaf, another shape that highly resembles a bookend, and a large shape down below that I do not know what the heck it is.

The first of those patterns is called a block-laying switch engine (or a type-1 switch engine).

The second is a glider-producing switch engine (or a type-2 switch engine).

[Bill Thayer]

Thank you! I need to give myself a course in terminology from LifeWiki just so I can look for things....

[b_flat]

Hello community!
I´m new here, Life gained my interrest about a year ago already though...
(i hope my terms are correct, sorry for the bad english)

I was just playing with some rules, and in the B378/S23 I found that a randomly drawn soup emerged a quite nice puffer around gen 42.000 or so.
not only this, somewhen around gen 86.000 a even more complex rake evolves right above, which serves as a eater for the first puffer...
what also confuses me is: besides those complex things it only emerges normal gliders, no spaceships since now (even though they exist in that rule)

Code: Select all

x = 44, y = 17, rule = B378/S23
17b6o$16bo5bo$16bo5bo$o16bo2b2o$b3o14b2o13b3o$4b4o5b5ob2o11bo3b2o$8b5o

17bo3b2ob2o$13b3o18b2o2b2o$15bo20b2o!

now i know that the puffer itself may be known, but i ask myself if there is something unusual about a soup emerging more complex struktures than gliders and small ships...
i newer saw something like this randomly emerging from a soup. especially not from conway...
is it only because of the additional Births of the rule?

are there any reference on such soups, that cause complex ships to emerge (even in conways rule)?


thank you for explaining!

[Extrementhusiast]

i newer saw something like this randomly emerging from a soup.

It all depends on the rule. In the original GoL, natural puffers are practically nonexistant. In B3/S2378, infinite growth is common but there are no "organized" puffers than I am aware of in this rule. In B36/S235, puffers occur in practically every soup that has infinite growth.

[calcyman]

In the original GoL, natural puffers are practically nonexist[e]nt.

There are two natural puffers, namely the block-laying and glider-producing switch engines. No other puffers have been discovered from random initial conditions.

[b_flat]

well, i see that B36/235 also has puffers, but it seem so me that they are a lot less complex that the one i found...
(by complex i mean the puffer exists with much fewer cells involved)

can you reproduce a puffer or similar object with such a complexity in a different soup/rule?
or if not, can you say, that one specific rule is the most "puffer-affine"?

sorry but i cannot find any information about this in the wiki.

[137ben]

@above: In life, a switch engine can start from only 10 cells. One way for this to happen is

Code: Select all

x = 8, y = 6, rule = B3/S23:T1000,1000
6bo$4bob2o$4bobo$4bo$2bo$obo!

But yes, some rules definitely have more natural puffers. As for how that could be measured, I'm not sure.

Hey, I'm new here. I'm not sure if this would be considered rare or interesting, but anyway... I was playing around with 8-cell patterns and an unusual still life popped up in generation 2276 and survived for a little over two hundred generations. It pops up at the bottom - the Life Wiki says it's called a Big S.

Code: Select all

x = 20, y = 5, rule = B3/S23
$b2o15bo$bo14b3o$17bo!

[Mats]

I don't know if the Big S is considered rare or not. In the Online Soup Search it's in 26th place among still lives and oscillators.

Here is a seven cell predescessor:

Code: Select all

x = 6, y = 4, rule = B3/S23
o$bo$bob3o$2bo!

Here is an eight cell pattern in which a Big S survives forever:

Code: Select all

x = 6, y = 5, rule = B3/S23
2o$bo$2b3o$5bo$5bo!

[137ben]

@davidspencer: the big S isn't that rare, but what is much more impressive is that you have found an 8 cell pattern which lasts for 5361 generations.

[davidspencer]

Mats - nice patterns, the seven cell one is pretty cool!

137ben - A long-lasting pattern was actually my initial goal. I ran into other (but not many) patterns which lasted longer, but I only saved one, stabilizing at either 6515 or 6422 depending on how you look at it. The final bit of chaos turns into a glider at 6422, which later hits a block and both disappear at 6515. I wonder if anyone has tried all the possibilities with the r-pentomino interacting with a blinker/block?

Code: Select all

x = 17, y = 29, rule = B3/S23

It consists of a pre-honey farm, two blinkers, a block, a beehive, a shape on the top that resembles a beehive right next to a theta spark, a shape on the left that generates a spark and an unimportant loaf, another shape that highly resembles a bookend, and a large shape down below that I do not know what the heck it is.

Pre-pulsar makes a p20 oscillator in a cylinder of width 8:

The unusual oscillator that you pointed out is very similar to the Great On-Off.

This is the general synthesis sequence: Start with a block on cap. Then, add a domino spark next to the end of the cap and off to the side (to turn the domino on top into an S-tetromino), and at about the same time, delete the block with a glider. (Even though it is simultaneous, it shouldn't be too hard to do.) Now here comes the hard part. Place the following reaction at the appropriate location:

The original soup shows where to put it (in the form of the appropriate spark generated). I have not managed to avoid this reaction conflicting with the reaction that creates the dominoes, in terms of the gliders interfering with each other. Then delete the loaf generated along with the second spark.

Or, use this reaction, but I have not managed to synthesize it:

OOO..

Here's the recipe I have for making that class of object. It's ugly, not obvious, and I don't have a record of who came up with either part.

Another construction that converts a static inductor into the active oscillating part would be useful, too.

(Converting the block in place to another object is an exercise for the student...)

Then there's this, by Dean Hickerson, which might help you, too.
