I tried to bent the glider loop in an IMG. How to reorganize the reflectors and reduce bounding box of this period-4635 (45×103) glider gun?

Looks like a non-180-reflected quinti-Snark makes a very marginal improvement. Can the drive gun be moved southeast, or does that start causing unwanted interference with the stream going in the other direction?

...

Moving southeast is possible with another 2-glider collision, but this does not make an improvement:

NW11T94 reduces the areas of the following gun periods, for a total of 1181 area saved:

345 (3410 -> 3380)
115 (3534 -> 3380)
342 (3102 -> 3050)
171 (4488 -> 3782)
350 (3410 -> 3380)
175 (3410 -> 3380)
395 (3776 -> 3685)
133 (4148 -> 4060)

gun_171's improvement is, by far, the most significant and the most awkward:

Answering some questions:

Here is a p9847 (43×229) pseudo-random number generator that releases 10 gliders per period.
...
A gun_9847 may be completed by taking a period-229 glider gun and applying an AND gate:
...
Please suggest a stable 5× pulse divider (not periodic period multiplier) to reduce its bounding box.

The "not periodic" limitation is just to produce a true-period p9847 gun, right?...

No. Using p5 quinti-Snark will give a p(9847×5) gun with chaotic outputs (try it out!). Say the smaller p9847 gun above is chopped to this, in which a glider arrives at the marked location at generation 400.

9847 is not a multiple of 5, so for each row there must be one and only one of n from {0,1,2,3,4} that makes the generation count divisible by 5. For a period-5 quinti-Snark to work, however, we need a row whose corresponding generation count is always divisible by 5 no matter what n modulo 5 is, so that it can be set as the output timing.
A working but ugly way to solve this is to use a period-43 quinti-Snark, which is shown as the second, larger p9847 gun above. Two guns have their outputs collide and throw a domino spark to support the quinti-Snark. It may be reduced if there is a glider eater that gives the domino spark with adequate clearance, but I know of none.

Is there a good way to produce an glider only if two input gliders arrive at exactly the right times? Seems like a p43 gun could maybe be set up as an "anti-filter" for a p229 gun, or vice versa, somehow or other, in a smaller space than that PRNG pattern. But I'm drawing a blank on exactly how that would be done.

One such example from catagolue involves a p104 (4×26) gun and a p44 (4×11) gun:

(Don't ask why it does not simply double the improved gun_2288)
But 43 and 229 are both prime, thus coprime, so the glider interactions happen at any possible timing, presumably making the result much complex.

But 43 and 229 are both prime, thus coprime, so the glider interactions happen at any possible timing, presumably making the result much complex.

Possibly it's not as bad as you might think (come to think of it). I haven't tried this yet, because I'm on the road to Chicago for the day... but Jormungant's universal regulator is surprisingly small. I wonder if something along those lines could be adapted for this purpose -- drive the regulator with one of the guns and use the other one as input.

Although it seems that syringe loops are going out of fashion (the current guns often remind me of guns1j, except they are much smaller). The reflector (runtime = snark + 28) is cribbed from the new gun_174 (it also works with p7 but then it does not duplicate the glider).

p56 Quetzal with pi version of speed tunnel

Not the smallest p56, I know, just playing around with the speed tunnel...

There's room to cut down the size quite a bit, with no cost in complexity on the left side. But yeah, it's hard to beat 34x29.

EDIT: switched to LifeHistory to show actual size, and reduced the boundary a little more.

I'm aware of the meatball. But I'm not convinced that reducing the BB at the cost of increasing population makes sense...

It doesn't have to make sense -- and it doesn't, really. This Pointless Optimization Game is an arbitrary exercise that has been going on since somewhere around the turn of the century -- or is "turn of the millennium" the right phrase?

The rules are simple: if you can fit a glider gun into a smaller area than the current record-holder for a given period, you have a new record-holder -- no matter what hideously convoluted things you have to do to save that last row or column. If you want low population, you have to go in and clean up most of those optimizations -- but there's just no market for lowest-population guns, or any other "reasonable" metric.

-- Don't worry, it really is more fun this way... as thirty-four pages of this thread (and counting) can attest.

It doesn't have to make sense -- and it doesn't, really. This Pointless Optimization Game is an arbitrary exercise that has been going on since somewhere around the turn of the century -- or is "turn of the millennium" the right phrase?

The rules are simple: if you can fit a glider gun into a smaller area than the current record-holder for a given period, you have a new record-holder -- no matter what hideously convoluted things you have to do to save that last row or column. If you want low population, you have to go in and clean up most of those optimizations -- but there's just no market for lowest-population guns, or any other "reasonable" metric.

Well, if you ask me, since I have been using guns to make static constructions of varying size, I do not care about either BB or minimum population. The actual metric that would be best optimize in my view, which relates to BB often though, is the diagonal width of the gun in the direction opposite to the output glider. The reason is simple, many construction with periodic guns needs glider collision in a specific location, and if many gliders are needed, one can lower the number of bouncing around needed if gliders can zip by the side of the gun, so that gun can produce diagonally close glider pairs, and lower the need for reflecting gliders for a given construction, the best case being an edge shooter. The diagonal direction in the direction of the glider would not need to be bounded, but minimized as 2nd lower priority criterion for uniqueness, I would think the aspect ratio of optimal solution would rarely go wild, I would love to see for what gun period that statement is wrong ^^.

Most often than not, I think the best gun according to the metric would still be similar to the BB, except it might be spared from the weird oscillator additions added that plague corners of some guns and increasing needlessly the total population just to remove 1 row/column.
