I'm currently compiling a list of 3o2$o! + domino → glider reactions on User:HotdogPi/3o2$o!, and I reduced gun_495 (45 and 55) and gun_4182 (82 and 102) this way. What else can I add to the list (especially edgy dominoes)?

Here's a p150 example (shown with a PD to release gliders)

Also, the p83 in your collection is actually p166, and Karel's p15 can also work as a glider releaser for periods 3n or 5n.

P38 flipper gun partial that just needs an extremely edgy dot:

A catalyst might work too.

After seeing area chart dominated by prime period guns of huge size, I started to think what can be done to shrink those 50k-120k monsters.
With period multiplication, which is used in many guns, prime periods were impossible to get.
Next idea was to add delays instead of multiplying them.
But for this idea to work, compact reflector with large delay was needed.
Thanks to confocaloid, I got such device.
Next it was needed to just add large not very precise delay with small more precise delay to get prime sum.
This is what I done, obtaining optimization for gun_2579 from area 67204 to 31772.
I'm sure this method can be significantly improved to get even more area reduction.
Also I did not learned much how smaller prime periods guns were made, so, probably, "my" method is already known and huge guns are hanging in database just because no one got to reupload better versions.

Yup, you've got the right idea -- and it's not just smaller prime periods. Even the current largest known prime in existence has an oscillator to go with it, using the same basic method of looping a bunch of times and then resetting the loop.

If anyone wants to try building more of these, the first thing that seems worth mentioning is that converting a glider to a Herschel and then a boat to stop the signal in the loop (as you do in the northwest corner above) is maybe a little bit overkill.

A more lightweight but less edgy solution used to be the beehive stopper. But that needs input gliders of a particular color to work, so you might have to add a Bandersnatch to correct the color half the time. There are more recent discoveries that can use a direct glider input to block a glider lane, no conversion necessary -- including a glider-to-block converter that works with either parity of input glider.

The boat that your mechanism places near the loop is (I think) guaranteed to work to stop the loop, no matter when it arrives (am I remembering that right?). But usually you don't need that universal regulator-like functionality -- especially with longer-period base loops, you'll usually luck out and the "stopper" still life will just happen to arrive at a workable time. If the stop-and-reset mechanism works once, then it will have the same timing next time around too -- and you'll have successfully avoided the bigger universal mechanism and will end up with a generally smaller pattern over all.

(If you're unlucky and the timing doesn't work, there's usually a trombone slide adjustment that can be made somewhere, to delay the input glider slightly until the looping signal gets past, and it will still probably be more compact than a bigger mechanism.)

It's a much trickier problem to write another universal generator script like chris_c's, that can automatically generate smaller guns for all of these periods. With existing methods, you kind of end up needing a new template for each small group of guns, which is almost as much manual work as just building each of the guns directly.

So there are two key components:
1. Extensibility of gun design.
2. Software which can generate lots of candidate guns based on templates and upload best of them to Catagolue.

Yup. There are many thousands of different ways to string together small "resettable loop guns" that are adjustable and have odd periods. Depending on the period multipliers on the "reset" circuit and the particular H-to-G that generates the reset signal, you can get significantly different starting periods. Jormungant experimented with building a few of these back in 2019, so for a while there I was calling them "Jormungant guns", though the idea is much older than that.

Each small configuration of loop + period multipler* chain + reset signal generator will produce guns that can contend for record-breaking small size, just for a small range of prime periods -- not that they can't be adjusted to more periods, just that inevitably as soon as a given "trombone slide" has been adjusted outward by a few dozen cells, a completely different configuration is pretty quickly going to end up being more compact.

We've had code available for twenty years (Hersrch) that can lay out simple candidate loops based on Herschel tracks. But nobody has ever quite gotten around to building the much more flexible software needed to experimentally lay out configurations for resettable loop guns, using all options from the new Snark//Bandersnatch/syringe/speed tunnel/ and semi/tremi/quadri-Snark technology. Preferably, a gun-builder program should then automatically test each configuration and see which ones just happen to break records.

It would be extremely cool to see a "simulated annealing" type bounding-box optimizer in action, where the input is a piece of circuitry with various adjustable parts, and the optimizer rebuilds it in various "nearby" configurations (move these Snarks out, move those Snarks in, re-weld, see if it still works). But our standard flat-bitmap representations of patterns are too stupid-simple to make it easy to get started on a project like that.

There's a format supported by LifeViewer and Golly that would support recursive pattern definitions along these lines -- but we don't have a pattern editor that can use that rather tricky format. So generally everything just ends up getting flattened back down into a plain bitmap after each edit.

* EDIT: Yup, as confocaloid says, "pulse divider" is a more precise term in this context. "Period multiplier" is a more commonly used term by about a factor of two on the forums (in 1990's mailing-list messages it was the other way around).

So "period multiplier" might be familiar terminology for a larger number of people, these days; this is discussed in the "period multiplier" Life Lexicon entry. Using the more familiar term doesn't have much of a downside in discussions like this, except for the subtle "underselling" that confocaloid points out below.

A terminology nitpick: semi/tremi/quadri-Snarks (as well as more recent discoveries) are actually pulse dividers. A pulse divider can also be used as a period multiplier (accepting an uniform input stream). However, a pulse divider doesn't require uniformly spaced input pulses to work. So in a certain sense, referring to pulse dividers as period multipliers "undersells" them: these devices can solve more problems.

The distinction between the two types of devices can be seen here in the case of engineered prime-period guns.
It's correct that prime periods are impossible to get with period multiplication (because multiplying a lower period will always result in a composite period).
However, prime periods can be obtained with pulse division (as already illustrated by the various examples posted by others).

With period multiplication, which is used in many guns, prime periods were impossible to get.
Next idea was to add delays instead of multiplying them.
But for this idea to work, compact reflector with large delay was needed.

... inevitably as soon as a given "trombone slide" has been adjusted outward by a few dozen cells, a completely different configuration is pretty quickly going to end up being more compact.

I decided to try adjusting some guns with custom made C# code.
First attempt was with gun_3593 - with slide adjusted by 142 cells, area of such gun was still competitive with guns present in database.
However, starting from 51 cells adjustment, gun started to explode or otherwise behave in wrong way.

Instead of figuring out what happened wrong with gun_3593, my next step was to prepare my own design for expansion.
I made gun with period 3741 and split it into 4 parts: base and 3 trombone slides:

(warning: code deletes files once they are uploaded!)

Code: Select all

using System.Collections.Specialized;
using System.IO;
using System.Net;
using System.Text;

namespace CatagolueUpload
{

            foreach (var rleFile in Directory.EnumerateFiles(".", "*.rle"))
            {
                var rle = File.ReadAllText(rleFile);

                var values = new NameValueCollection();
                values["content"] = rle;

                var response = client.UploadValues(postUrl, values);
                var responseString = Encoding.Default.GetString(response);

                if (!responseString.Contains("RLE is well-formed"))
                    throw new Exception();

                Console.Write('.');

                File.Delete(rleFile);
            }
            Console.WriteLine(" Done");
        }
    }
}

Result is 127 updated guns (if I made everything correctly!):

Next I want to make updated area chart. But for it I need to wait, to see if I made mistakes or not this time.

Yellow line (average) dropped noticeably.
Next goal is to drop red line (maximum) as well.

To achieve this I improved program from my previous post by adding enumeration of multipliers (1, 2, 3, 4) and mod 8 values (1, 3, 5, 9):

Since you've already written scripts to reduce a whole bunch of 4-digit guns at once, I have a suggestion. There are a whole bunch that are twice a much smaller gun where it would be much better to just add a semi-Snark to the one that's half its period. The same is true for ×3, ×4, etc.

Since you've already written scripts to reduce a whole bunch of 4-digit guns at once, I have a suggestion. There are a whole bunch that are twice a much smaller gun where it would be much better to just add a semi-Snark to the one that's half its period. The same is true for ×3, ×4, etc.

This is what I started with.
Here is my visualization for x2 periods:

Few thoughts:
1. Not only ratio for area matters, but absolute difference as well;
2. x22 and x33 periods were more promising. I saw x3-x4 area ratios there;
3. I don't think it makes sense to automate this task:
3.1. Humans can pack components better, at least for now;
3.2. There are not that many cases for improvements in fact. For example, adding component to diagonally shooting gun can easily double its area. Each case is unique and require attention.
