Execution of Old Guns by Variable-Speed Firing Squad

[WhiteHawk]

While not dependent on P80n or x12 multiplier, it's still 80*12*n (n=9): Guntrue_8640 reduced by 1 row (2508 -> 2451)

Code: Select all

A silly addendum: turns out that there was a different way to shave off yet another row from Guntrue_8640 (2451 -> 2394)

I managed to significantly reduce the p7 using LLS. I also shortened the p5 by one row using JLS (Edit: according to LLS using the same p7, the p5 could potentially be reduced by at most 6 more rows):

Some minor further reductions are probably possible, but I don't think it will get much smaller than this without a new gun mechanism.

The true-period p35 gun is now smaller than the record pseudo-period gun, shown below for comparison:

EDIT: I almost got fooled just now into thinking an aircraft carrier in the gun above was actually an important part of said gun. This is why this densifications is a problem for people using Catagolue.

Anyway, here is a cleaned-up version of the gun above, which is what the form in Catagolue should look like.

Guntrue_6080 reduced by a lot (6006 -> 4134)

Code: Select all

Guntrue_3040 reduced in a similar fashion (5467 -> 3978)

Code: Select all

...

EDIT 6: Turns out, the slightly older support for P76 pi hassler doesn't just help it work in Pedestrian Life, but it shaves a row off of guntrue_6080 too

Code: Select all

This April 1st, joke's on me! Guntrue_3040 get 1 more row shaved off as well (3978 -> 3900)

Code: Select all

Well, April fool's - it's just one for now. But seriously, the current Catagolue forms for Guntrue_4960 and Guntrue_5440 are outdated and should be replaced

Also, why is Guntrue_4720 not yet in Catagolue?

EDIT2: gun_4720 reduction (infinity -> 3360)

Code: Select all

(also gun_4720 wasn't infinite/undefined at the time of this post due to my less optimized version posted earlier, but that's beyond the point because this one is smaller)

What is perhaps of more interest is where the reduction takes place, namely in what (I think) is a glider-to-pi heptomino converter, which may be more broadly used, in the top-most part of the gun.

Update: Indeed, this can also be used for a 1-cell reduction in the smallest p65 glider gun in Catagolue as well.

That's a speed tunnel. The 30-cell catalyst that you've made a 29-cell version of can be seen in the Jubjub reflector. Both variants are often called "drifty eater 3"; the 29-cell form can be seen here, for example. The Eater 3 article also has the 30-cell form.

The cost savings comes from reducing the clearance at the bottom of the catalyst, kinda sorta substituting a table inductor for an eater head.

There's an alternate catalyst shown in the speed-tunnel article with only 19 cells and much better clearance -- but it sticks up two cells higher, so it's not optimal in the context of the p62 gun.

[jeremydover]

Excellent, thanks for the education dvgrn! I don't really grok circuitry beyond the highest level sense, so it is useful to see it in action.

And since I'm here, the p69 glider gun in Catagolue admits a 4-cell stator reduction: it gets 1 cell from the same speed tunnel reduction as p62 and p65, but there's also a 3-cell reduction in the still life at the muzzle of the gun which fashions the glider:

Ha, I think that might be a new one! It's a lower-population variant of the catalyst in the PSE3T-5 converter. Technically I suppose it's also just slightly lower clearance to the southwest and south, but not by an amount that will often cause trouble. And it's higher clearance in the southeast, anyway.

I'm thinking that it might be a new variant, just because it isn't in Jormungant's most recent (2024) elementary conduits collection, which has the following for "PSE3T-5", matching what's in Catagolue for the p69 gun:

Those systematic IDs for Herschel-to-glider converters usually get mentioned when an improvement is made. But there just aren't a lot of matches for "PSE3T-5" on the forums so far.

Notice that the ridiculous period-3 thing at the top of the converter in the p69 gun ... is really just a plain fishhook eater, turned into an oscillator at the cost of a much bigger population -- but saving one column in the gun's bounding box.

Long story short, population optimization isn't really consistently done in Catagolue's gun collection -- not yet, anyway. Until Scorbie's pull request for the gun recognition algorithm goes in, it isn't even possible to replace existing large-population guns, with new guns like the ones you're coming up with (with smaller population but the same bounding box).

[...] Until [...] pull request for the gun recognition algorithm goes in, it isn't even possible to replace existing large-population guns, with new guns like the ones you're coming up with (with smaller population but the same bounding box).

As far as I can tell, the only recent pull request is already merged. However, it didn't even attempt to implement "preferring lower bitcount when the bounding box is the same", that change only aimed to resolve the old "bounding box glitch" bug. Related discussion viewtopic.php?p=210279#p210279

Got it. I'll stop spamming here in that case, unless I can find a bounding box improvement. Thanks for the guidance!

[dvgrn]

Got it. I'll stop spamming here in that case, unless I can find a bounding box improvement. Thanks for the guidance!

We do kind of want to keep some attention on the problem of getting Catagolue to accept lower-population same-bounding-box guns, though -- it would finally solve the problems our that mysterious Pointless Densification Spammer keeps causing, of submitting guns with piles of extra garbage inside the bounding box. One of these days! So this was a good series of reminder posts.

Anyway, things like the new PSE3T-5 variant are definitely interesting and worth collecting. There are collection threads scattered around where it might work best to post these things; the PSE3T-5 variant might go in The Hunting of the Elementary Conduits thread, for example. If you're not sure where something might go, the Thread for your unsure discoveries can be a good starting point.
