### Re: Small Four-Digit Prime Period Guns

How about yet-another-family of prime guns?

Here is a p1759 glider gun:

This strategy is more flexible than the h-to-g4 I used before, so it could still be useful for far larger primes.

There is additional flexibility in that it is possible to replace the 2x pulse divider. For example, here is a p2579 glider gun in 168-by-145 (down from 169-by-185). Two out of three pulses are absorbed; third pulse is split into two gliders, one of which is sent to the beehive factory, and the other becomes the output glider of the gun.

### Re: Small Four-Digit Prime Period Guns

Indeed, that's what I meant by more flexible, though there is also a way to not have to worry about period multipliers with multiple outputs:

this describes a P ((836+8X)*Y + 119) gun family, because that off loop has a quadri-snark in there (Y=4), but one can alter to main loop to change the base the base 836 to something else, but the usual shift of the snark pair trombone gives that +8X family. since Y can be defined with chained quadri-snark, like the original reset guns, that can be used in a similar fashion, now the question is if that is more compact, I am not sure I found the best way here, it is comparable to previous stategy, but fitting that g-to-h-to-g in the middle of the loop felt constraining, now it is a g0-to-g that takes slightly less space.

addendum: the more general question is if there are more circuits that if overclocked with a specific delay, causes only the first signal to go through, and either A- the second signal is cleanly removed, B- leaves some still life that will supress the following "first" signal or C- deflect the second signal into a different path. The main contraint for prime guns is that the h-to-g0 needs odd differences in delays, sadly it is mostly even for the one in the collection, that being said, there is are 2 ways to engineer almost all odd delays deltas:

### Re: Small Four-Digit Prime Period Guns

Another way is to insert another pulse divider in the track before the x2, instead of replacing the x2. Two examples:
gun_8719 in 172-by-147 (down from 189-by-161), by combining the stable x5 pulse divider and the same 2H-to-G pulse divider sending alternate output gliders in opposite directions on the same lane:

And here's a p30671 glider gun (a five-digit prime number) with bounding box 143-by-122, using the (7+6n)G-to-H pulse divider instead of the x5. Other periods can be obtained by adjusting trombone slides and/or the pulse-division coefficient; however, I do not see an obvious way to adjust this arrangement to a four-digit period:

Unlikely events happen.
My silence does not imply agreement, nor indifference. If I disagreed with something in the past, then please do not construe my silence as something that could change that.

this describes a P ((836+8X)*Y + 119) gun family
It have similar problem to exploding guns before:
Some combinations of variables produce incorrectly working guns.

This time gun always start working correcty after some stabilization time, but if I upload it "as is", Catagolue will reject it.
Instead of trying to find a way to always produce perfect gun, I made changes to my code to "normalize" gun before writing it to file.

Normalization works horribly slow right now (~10 sec for gun validation/normalization), either I made some mistake or code just needs to be optimized.
With small changes, this code will also allow to filter gun family with occasional explosions, to prevent Catagolue from clogging.

this describes a P ((836+8X)*Y + 119) gun family
It have similar problem to exploding guns before:
Some combinations of variables produce incorrectly working guns.
Yes... either the hive stopper or the g0-to-g that leaves a hive behind can interact incorrectly with gliders on the loop, the "off loop" part can be modified to be slower get produce the same period (it has no influence on the period, just on whether is blows up or not, or a different non-prime period if it deletes the wrong glider in the pair separated by 119 ticks.

for example, the P3463 prime gun I posted earlier would explode if I did not add attach a g-to-g component to a snark, that just slows it down by 34 ticks, (no influence on the period):

basically, one can push away diagonally that "off loop" bit, there exist a range of offsets for gun where it work as intended, but that depends on the component you used to define Y, and the location of the glider are intercepted (before the trombone bit is in sync, after it is not.)

### Re: Small Four-Digit Prime Period Guns

Having non-exploding guns is important for lowering maximum area line.
However families with occasional explosions are valuable as well, because of optimization potential.
They will leave spikes on maximum area line, but will allow for deeper "cut".

### Re: Small Four-Digit Prime Period Guns

After my first failure with gun_3593 family, I decided to test different approach.

Before I tried to predict behaviour of all guns in family.
Now I just iterate over all possible variable values in some range, simulate every generated gun and classify guns based on simulation results.

Code below contains some speed and readability improvements, but it is not enough: with this code, checking of 1616 guns took 2 hours.
Rewriting this code in C++ can speed up execution by approximately 50 times, making this approach usable enough.

Code below contains some speed and readability improvements, but it is not enough: with this code, checking of 1616 guns took 2 hours.
Rewriting this code in C++ can speed up execution by approximately 50 times, making this approach usable enough.

How about rewriting the code to use lifelib via Python 3? (Tutorials/lifelib)
Things like evolving a pattern by n ticks, translations, parsing and generating RLE are already implemented. (The generated RLE would be actually run-length encoded, reducing the volume of submissions in batches.)

However it looks like automating this task will consume more time than manually adjusting these guns.

How about rewriting the code to use lifelib via Python 3? (Tutorials/lifelib)
I will consider this option if I decide to port my code to other languages, thanks.

The generated RLE would be actually run-length encoded, reducing the volume of submissions in batches.
Is it that important? Catagolue prettify uploaded data anyway.

One of the goals of my code is to show how many things can be achieved without external dependencies and with relatively small program size.
If I rewrite `WriteRLE` function, it will become large without providing much advantage.
Also now it is 100% bug free. If I add real RLE compression, then I may also add bugs, which may be hard to track with 4 hour data processing intervals of Catagolue.
I may do it however. Will think about it more.

The points about avoiding bugs and keeping the code simple and self-contained are valid points.

One potential advantage of RLE compression, is that it can become easier to reuse the same code (once written and debugged) in other CGoL projects, as long as it's a function that accepts a pattern and returns conforming RLE.

One actual advantage, for submitting glider guns (or glider syntheses) to Catagolue, would be a significant reduction in the volume of update logs (for example: 7123031375, 7139015761) and the intermediate readsynth queue.

The logs include every submitted RLE, almost unchanged (except for the header); prettification happens at some later point. As a consequence, some logs (for example 7117451250) become too large to be preserved, and there's a message at the end that says "Job's log exceeded limit of 4194304 bytes. Job execution will continue but no more output will be collected." which means some information of interest (e.g. details about processing later RLE submissions, the list of apgcodes at the end) can become lost/unavailable.

### Re: Small Four-Digit Prime Period Guns

I rewrote WriteRLE function.
It's still not perfect, but should not overflow Catagolue logs anymore.

Also I processed p00827 family, 42 guns were uploaded:

Of course, my programs can be used to generate non-prime guns as well.
But, except for corner cases, they will be larger than prime gun + period multiplier.

As for more general question of filling database with new autogenerated content - I don't know if this is good idea.
Probably, separate discussion is needed for this question.
However, any person can do it without discussion and I'm sure it will happen sooner or later, so, maybe, there is no sense in making restrictions.

Since my answer is not good enough, it's better to wait for other opinions.

### Re: Small Four-Digit Prime Period Guns

Prime-period guns cannot be easily obtained from lower-period guns by period multiplication. (While period multiplication can be done in several different ways to obtain composite periods.) A very compact prime-period gun implies reasonably compact guns for multiples of that period.
At the same time, there are "few" four-digit primes (1061 out of 9000), so practically it makes sense to focus on them.

That being said, some composite periods still remain interesting (e.g. products of two large primes), and this forum thread already contains some composite-period guns.

### Re: Small Four-Digit Prime Period Guns

I significantly changed my gun generation script:
1. Simulation is 5 times faster (now 1 gun needs ~1 second to validate);
2. Parameters generation is separated from validation;
3. Guns are generated in random order to produce more uniform load.

Also this script allowed to process gun_9973 family:

upd. I executed few more passes of this algorithm, added several new guns to cut the spikes from minimum (blue) line and here is how area chart looks now:

Also this script allowed to process gun_9973 family:
These runs and the resulting reductions are impressive.

One thought here, is that the collection of four-digit guns might become "more or less completed" (with reductions slowing down) after finitely many improvements. Catagolue doesn't collect periods above 9999. (And perhaps it shouldn't collect them; I think it would become impractical to collect individual guns at that point.) This leads to the idea of a software tool that would loop through all known gun families/gun designs, and automatically assemble "on demand" a compact gun of any higher period.

If you keep the code for "already processed" families, it might be possible to collect all that code into a single combined software tool. The input would be the desired period; the output would be either the most compact gun of that period that can be made, or multiple guns (one gun from every known family) sorted by the bounding box area.

Four-digit period guns are compact and easily adjustable because two snarks allow for x1..x16 multiplication.
To achieve larger multiplication, code will need to support adjustable multipliers (or variable amount of multipliers).
It is possible, right, but not as easy as collecting already available designs in one place.

Well, I had to try already, at least... So, here is a P1993 gun, so a valid entry for the proof of concept:

This is quite versatile as you might have guessed. Variants will be needed to fix the 8-way parity issue, but this should allow to cover the whole 4 digit range (and beyond).

There are 5 guns left to optimize for achieving sub 25k maximum:
"gun_3529","30090"
"gun_3457","29040"
"gun_3449","28875"
"gun_3433","28536"
"gun_3361","26404"
[...]
All five periods are 1 (mod 8) and in roughly the same range, so could be covered by a single design.

Here is gun_3361 in 144-by-132 (down from 164-by-161), using the same design as above, but with a different Herschel-to-glider converter used in the pulse-dividing track:

Unlikely events happen.
My silence does not imply agreement, nor indifference. If I disagreed with something in the past, then please do not construe my silence as something that could change that.
