Small predecessors of common objects and evolutionary sequences

[otismo]

First of all, calling a process Evolutionary when it is, in fact, Simple Progression

only furthers the mis-understanding of Evolution and promotes the slang usage of evolutionary, etc.

Life patterns Progress; they definitely do NOT evolve.

Your interest in Predecessors seems to be LowBit/SmallBoundingBox/EdgeShootable -

I am interested in HighBit/MaxGens/FireClouds - like this 18bit Pulsar Predecessor :

Code: Select all

x = 11, y = 4, rule = B3/S23
b3o3b3o$b3o3b3o$o3bobo3bo$2bo5bo!

My interest in Predecessors would seem to be included per the title of this thread;

would my stuff be clutter ?

Thank You !

Cheers !

Thank you for bringing that to my attention. I have clarified the title.

I posted this into the "accidental discoveries" thread. 9 cells creates a very long ship plus a few other things. I know it's a rare object, but I still found it interesting.

Generation 32 gives a nine-cell parent for a clean very long ship if one replaces the duoplet with a dot spark.

Code: Select all

x = 5, y = 6, rule = B3/S23

I was able to modify it in order to yield other nine-cell parents.

Also, the dead spark coil isn't very common. If you want to be helpful, please try to find small predecessors for long barges, aircraft carriers, long ships, integrals, or any objects already covered for which I missed minimally sized predecessors.

Thank you. I have added it.

Here are five more patterns to add:

Code: Select all

x = 36, y = 43, rule = B3/S23
2bo$bobo14bo2bo13bo$o3bo13b4o10b4o$bo3bo26bo$2bobo$3bo17$17b8o18$20b2o
$19bo2bo$19b4o!

The top three are sparks. The table and the Z-hexomino are probably minimal, but there could be some 6-cell predecessors. The one on the left is likely not minimal.

The constellation forming from a line of 8 is seen often enough (although probably not from the line of 8 itself). I don't think it's possible with 6, but I can't rule out 7 (even though it's symmetrical, it doesn't have to begin that way).

The last one is the interchange with spacing 4 (the most common form by far) — I'm surprised you haven't included it yet.

[MathAndCode]

I just added a bunch of still lives to the list. Please let me know if I made any errors or omitted any predecessors with minimal population.

Looks mostly good to me, although I didn't go through to check every single predecessor if I knew of multiple at a given minimum population. Here's an 8-cell hat predecessor, the only one I know of but not necessarily the only one that exists:

Here's an even more edgeshootable traffic light predecessor. The four on the left are the ones you already have, and the one on the right is the new one.

According to Achim Flammenkamp's census page, a very long boat has an eight-cell predecessor, and a very long ship at least has a dirty eight-cell predecessor. However, I can't seem to find very long boat predecessors with fewer than nine cells, and I have no idea what the eight-cell dirty long ship predecessor is/predecessors are. Does anyone know what patterns Achim Flammenkamp was referring to?

I'm interested in tracking edgeshootable predecessors, not edgeshooting predecessors. The predecessor on the right edgeshoots a shield pentaplet, which I already have listed as an edgeshootable predecessor.

You might want to add these three. The first two I posted in another thread (the naming proposals thread, without giving a name myself), and you (the OP) commented on it, and the third is in a late generation but is the most recognizable generation of the pattern to me. (I feel like the second one is also in a late generation, but what I do with my program requires using patterns after they've all converged, while the purpose of this thread is different.)

Code: Select all

x = 45, y = 6, rule = B3/S23

Since the honey farm with 6 cells entry is so large, you might want to split it into four subcategories: these three and "other".

Code: Select all

Do we have a list anywhere of absolutely everything that can be made with 6 cells?

[MathAndCode]

The right one only requires seven cells.

Code: Select all

x = 7, y = 3, rule = B3/S23
o$bob4o$2bo!

However, I don't plan to add any of them because they aren't very common, they don't have well-defined names, and I am seeking to focus on adding still lives now.

This thread was originally made to answer the question, "Why is so-and-so pattern so common?" I don't see how splitting up a category would serve that purpose.

I made this and it ended up being a seven generation predecessor for Kok’s Galaxy.

Wow! That's impressive! Unfortunately, Kok's galaxy doesn't qualify as common (with no C1 or G1 soups), so I don't want to add it.
By the way, for the future, it is recommended to provide patterns as RLEs in [code][/code] tags so that other people can run them more easily, such as the following for your pattern.

Code: Select all

x = 9, y = 9, rule = B3/S23

That's how Jan Kok first discovered his galaxy. Nice re-discovery!

I'm interested in tracking edgeshootable predecessors, not edgeshooting predecessors. The predecessor on the right edgeshoots a shield pentaplet, which I already have listed as an edgeshootable predecessor.

Interestingly, that predecessor is edgeshootable:

Is a skewed paperclip common enough that this ten-cell predecessor should be added to the first post?

It's not in the list of common still lives, so I guess no.
