## Execution of Old Guns by Variable-Speed Firing Squad

For discussion of specific patterns or specific families of patterns, both newly-discovered and well-known.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

Simeks's new HF73R gets the lane spacing just right for a new gun family, setting records at periods... *checks spreadsheet* 166, 174, 249, 253, 257, 261, 265, 269, 273, 277, 281, 289, 293, 301, 305, 313, 317, 498, 506, 514, 522, 530, 538, 546, 554, 562, 578, 586, 602, 610, and 626.

I think.

Happy holidays, folks.

It becomes the 3rd most productive gun in the variable collection relegating the previously respectable p482 to a handful of records at small extensions. Kazyan wrote:EDIT: Closer weld.

That weld would also allow the p448 to become a p440 but since it doesn't set any new records I won't make another update. From your horde of fixed gun improvements I liked the L112 variant that has a smaller South-East extent than the standard version: x = 27, y = 43, rule = LifeHistory15.B$14.3D$14.BDB$13.3D2B$13.5B$12.6B$12.6B$13.5B$13.6B$12.6B$12.7B$13.6B$13.6B$13.6B$12.8B$11.8B$11.9B$11.9B$10.10B$10.3B2A5B$9.4B2A5B$4.2A3.11B$4.A2.A12B$2A4.2A2.8B$.A9.7B4.2A$.A.AB7.6B4.A$2.2AB.3B3.6B.BA.A$4.14B.B2A$4.16B$5.14B$4.17B$2.19B$19B.B2A$2BC15B2.BA.A.2A$2BCBC4B.7B6.A.2A$2B3C4B2.6B6.A$4BC4B2.6B2.2A.2A$8B3.6B3.A.A$B10.8B.A.A$9.2AB.2B2.2A.2A$8.A.AB6.A$8.A7.A.A$7.2A7.2A! chris_c Posts: 891 Joined: June 28th, 2014, 7:15 am ### Re: Execution of Old Guns by Variable-Speed Firing Squad I didn't check all the guns on that list for reference, so please forgive my ignorance, but is this SE weld any kind of improvement (at least for bounding box)? x = 25, y = 43, rule = LifeHistory15.B$14.3D$14.BDB$13.3D2B$13.5B$12.6B$12.6B$13.5B$13.6B$12.6B$12.7B$13.6B$13.6B$13.6B$12.8B$11.8B$11.9B$11.9B$10.10B$10.3B2A5B$9.4B2A5B$4.2A3.11B$4.A2.A12B$2A4.2A2.8B$.A9.7B4.2A$.A.AB7.6B4.A$2.2AB.3B3.6B.BA.A$4.14B.B2A$4.16B$5.14B$4.17B$2.19B$19B.B2A$2BC15B2.BA.A$2BCBC4B.7B6.A$2B3C4B2.6B6.2A$4BC4B2.6B2.2A3.A$8B3.6B3.A2.A$B10.8B.A.A$9.2AB.2B2.2A.2A$8.A.AB6.A$8.A7.A.A$7.2A7.2A!

I'm nearly certain that it's a population improvement only. The conventional version of the L112 is tucked further in to the right, and for the variant where that weld would be used, the edge of the gun is held by reflectors instead of the conduit. Here's the L112 in the H-to-H collection for reference: x = 31, y = 45, rule = LifeHistory22.B$21.3D$21.BDB$20.3D2B$20.5B$19.6B$19.6B$20.5B$20.6B$19.6B$19.7B$20.6B$20.6B$20.6B$19.8B$18.8B$18.9B$18.9B$17.10B$17.3B2A5B$11.2A3.4B2A5B$12.A3.11B$12.A.A7BD4B$7.2A4.2A2.4B3DB$8.A9.2B2D2BD4.2A$8.A.AB7.6B4.A$9.2AB.3B3.6B.BA.A$11.14B.B2A$11.16B$12.14B$11.16B$9.18B$7.19B$7.2BD15B$6.3BDBD4B.7B$7.2B3D4B2.6B$6.5BD4B3.6B$5.10B6.4B$4.4B12.B2A2B$4.3B14.2A.B2A$2.4B18.BA.A$2.2A23.A$3.A23.2A$3A$A! Also, crossing some streams yields this p762 gun family, which sets a record at 778 and probably a few more higher periods.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

As a test of LLS, I shaved four cells off the p498 gun. That's optimal for this exact rotor.

Script now generates 177 guns. Haven't picked up this project for a while. There must be something else even less pleasant that I should really be doing, like updating my resume. I got tired of copying and pasting RLE into the script, so the multistate template guns are in a "template" folder that the script expects to be pointed at. The script can now build 700 guns -- or actually it can build 358 guns, and it more or less knows where 342 more of them are, so they can be copied verbatim out of the "fixed" or "variable" folders. The script doesn't do that yet, but it will -- the goal is to run the script and get a single folder containing the latest-and-greatest thousand guns less thirteen. The next hundred guns will be easy to add, since they're in families with seven to nine guns each. The next hundred are in families with four to six guns each, so they aren't too horrible either. But the last hundred are a big pile of one-off (or two-off) adjustments. If anyone else wants to work on coloring in some of the remaining gun templates, please be my guest! I can even provide documentation -- on request. All the current code is in the attached file. 358-variable-guns-from-script-3March2018.zip template folder, gun folder, current gun-builder script (213.76 KiB) Downloaded 259 times Originally I was getting dozens of warnings, because I had made sub-optimal adjustments to some guns: bad size 370 (6018, 'p00652_11_p00370'): really 6120 I figured them all out eventually, but it sure took a while. I'm finding it a little hard to imagine a script that knows how to figure out all the minimal adjustments for some of these ant's-nest pretzel loop guns. I guess a reasonable way to do it would be to generate all possible adjustments in a large range, and then just run each one and find out how long it turned out to be, and pick out the smallest bounding box for the period you want. But I think that implies some general knowledge of what pieces can be welded to what other pieces, at what depth. It would be painful and bug-ridden code if I wrote it, that's for sure. It's much easier to just build "alt" gun templates by hand, really, especially for the custom weld cases. Speaking of which, I'm in great need of a competent welder for p00498alt1. My welding job got a little out of hand, and I refused to care because it didn't change the bounding box: x = 70, y = 51, rule = LifeHistory34.C11.2C$11.C11.C.C7.C.C10.2C$9.3C11.2C.C.2C3.C.C$8.C5.2C10.C.C.C.2C.2C$8.2C5.C7.2C.C3.C.C$15.C.2C3.C2.C.4C2.C.2C$16.C.C4.C3.C3.C.C.2C$18.C.3C3.C3.C.C26.2A$17.2C.C4.C3.C.C27.2A6.2A$3.2C20.2C3.C25.A9.A.A$2.C2.C50.5A5.A$2.C2.C53.A3.2A.2A$3.2C51.2A3.A2.A$C37.2C16.A3.3A.A$38.2C18.A4.A$53.2C2.5A$52.C2.C5.2A3.2A$53.2C.2C2A3.A2.A$54.C.C2.A.2A.A.A$54.C.C3.A.A.A.2A$41.2C12.C7.2A.A2.A$42.C25.2A$39.3C$10.2C15.2C10.C$10.2C2.2C11.C.C16.2A5.2E$14.2C13.C17.A5.E.E$6.2C21.2C16.A.A3.E$6.C2.2C26.A10.2A16.2A$7.3C.C23.3A28.2A$12.C21.A$7.5C22.2A$7.C11.2A$10.2C8.A45.2A$10.2C8.A.2A42.2A$21.A2.A$22.2A$37.2A$37.2A2$66.A$65.A.A$46.A3.2A14.A$45.A.A3.A$44.A.A3.A$40.2A.A.A3.A$40.2A.A2.4A.A4.2A$44.A.A3.2A3.A.A$40.2A.2A.A.A6.A$41.A.A3.A.3A2.2A11.D$29.2A10.A.A4.A2.A16.D$29.2A11.A6.2A15.3D!

It seems fairly sinful to replace a 7-cell still life with a 33-cell oscillator just to save one row/column but rules are rules I suppose :) Also I came up with a minor variant of the p3-eater that is usable in the p36, p75 and p87 guns: x = 259, y = 58, rule = LifeHistory206.2A11.A$205.B2AB9.A.A$206.3B9.A.A2.2A3.A$205.B.B9.2A.2A2.A2.A.A$205.5B8.B2.A.A3.A.A$125.2A5.2A71.6B6.2ABA2.4A.A21.A$124.A2.A.BA2B.A70.8B4.2A.A.A3.A22.BAB$124.2A.A2BAB.AB71.13B2.A.AB2.A15.2A5.AB$47.A77.A.A2.A2.A3BA2.B63.13B5.A.A2B.A14.A5.2BABA$45.3A76.BA.3AB4.2BA.2B2A60.15B5.A2B.2A11.BA.A6.A.2AB.2A$44.A78.A3B.2A3.A7B2A8.2A50.8B2A5B4.3B12.2A.B2A8.6A.A$44.2A77.3BA6.13B4.B2AB48.9B2A6B.B.2B12.B2A2B11.2B4.A$41.5B75.3A.A7.6BA7B3.3B49.13B2A14B6.4B13.4A$40.4B76.B4A8.A4BA9B3.3BA46.13BA2BA14B3.6B12.BA.B$40.5B44.2B30.A.B10.B3A17BA44.14BA2BA14B2.6B13.BA.2A$40.5B43.4B43.20BA43.2AB3.9BABA15B.7B9.2A3.A3B$39.3BA2B41.B.7B4.2A35.19B43.A2.A4.35B6.2B2AB4.BA$39.2B3A2B39.2A3B3A2B3.B2A2B18.A11.5B.14BA43.A.2A5.2A4B3.B2.2B2.17BA2B5.4B6.BA$32.2A4.3BAB2AB39.2A3BABA3B3.4B17.A.A9.4B2.14B2A43.A7.ABA3B14.12B5A4B.7B.BA.A$31.A2.A4.7B40.2B.A13B.BA14.BA2B9.18BA2B33.A8.2A6.3BA5B14.11BA2BA12B.B2A$31.A.A.BA2.7B43.A4B2A8BA.A14.2B10.19B34.BAB14.4B4.2A15.8B3A2B2A13B$32.A.2BAB.7B43.3BAB2A9BA12.6B.3B5.11BA6B35.BA14.4B5.A15.9B2A2B3A13B$8.B25.B.A.6BAB42.A3B3A5B2AB.B13.5B2A4B4.9BABA6B33.ABA2B12.4B7.3A12.9BA19B$7.3A23.A2B3.3B3A2B40.A2BA9B2A15.2A4B2A8B.8B3A6B.B27.2A.B2A.A12.4B10.A10.2AB.3B2.2B2ABA16B$7.2A25.2A3.4BA2B40.BA4B2A9B14.2A16B.16B2A25.A.6A12.4B21.A.AB6.3B3A7B.9B$5.AB2AB29.BA2BA2B40.2BABAB2A9B15.B.6B3A8B.8B2A4B2A25.A4.2B3.2A7.4B22.A8.5BA6B2.11B$.2A.3B.A30.B3A2B41.5BABA9B17.6BABA9B4.4B2A5B27.4A4.B2AB5.4B22.2A7.12B3.BAB.B3.3BA$A.3A2BA28.8B40.8B3A7B18.6BA11B5.3B.6B28.B.AB3.3B5.4B31.10B6.A.A.2A3.ABA$A4.BA28.2B3AB43.8BABA6B18.19B10.2B30.2A.AB4.B.B3.4B31.4B.6B4.3A.ABA5.2A$.4A29.2BA2BAB42.4B2A4B2A6B10.2A4.2BA18B9.2BAB29.3BA3.6B.4B31.4B3.B.B5.A3.A4.A4.B$2.B.2A28.2BA4B3.2A38.2BA2BA11B9.B2AB3.2A14B2.4B9.A.A29.AB5.10B31.4B5.3B4.2A2.A.4A$.2B.2A27.2B3A3B3.2BA38.2ABA3B.8B4.B4.4B.2BA14B.5B11.A29.AB6.9B7.2A22.4B5.B2AB9.A$.3AB20.2A7.BA6B.A.B37.3BA6B.6B.3B2AB4.2B2.20B44.A.AB2.4BA5B8.A22.4B7.2A12.A$.2B21.A2.A6.7B.BA2B.A35.3BABA4B.9BAB2A2.6BABA18B44.2AB.4B3A3B6.BA.A21.4B21.2A$AB12.B7.A2.A.A6.7B2.AB.A.A34.4B2A2B.7B.7B.2B2A5B2A14B3AB45.6BAB2A2B2.3B.B2A10.A10.4B$A.AB.5BA6B4.A3B.A7.7B4.A2.A32.2AB.5B2.2ABA9B.4BABA3B3A2B2.9BA4BA44.9BA9B12.3A7.4B$.2AB.B2A2BA3BA3B3.AB.2B8.B2ABA3B4.2A32.A.AB.4B3.B2A3B.6B.6BA6B5.7BA6B44.3B3A2B2A9B15.A5.4B$3.2BA5BA2B3A2B4.3A8.2B3A2B39.AB11.B4.8B.3BAB2A.4B6.13B44.3B2A2B3A8B15.2A4.4B$3.B2A2BABA3B3A2B5.B9.3BA3B40.AB15.11BA2BA2B.4B8.2A7BA45.3BA2BA11B14.5BA3B6.2A$3.2B2A3BA8B4.B3.B5.7B41.3BA13.6B2A4B2A4B.4B7.2A2B.A2B48.2B5A12B14.3BABA7.A$4.2B3A21B2.8B41.2A.AB12.6BABA8B3.4B8.B2.A3BA47.3BA17B2.2B2.B3.4B2A5.2A.A$7.21B3A9B42.B.AB11.7B3A8B4.4B13.BA49.35B4.A2.A$9.B3.B4.8BA3B2A7B42.4A11.9BABA5B7.4B12.A51.7B.15BABA9B3.B2A$12.B5.2B3A3BABA2B2A6B41.A4.2B9.9B2ABABA2B8.4B12.3A48.6B2.14BA2BA14B$11.3A4.2B3A2BA5BA7BA40.A.6A8.9B2A4BAB9.4B13.A47.6B3.14BA2BA13B$11.2B.BA3.3BA3BA2B2A2B.2B.ABAB40.2A.B2A.A8.2A9BA2BA11.4B60.4B6.14B2A13B$10.A.3BA4.5B.A5B6.2A2B43.ABA2B4.B.B2A5B3A3BA13.4B59.2B2AB12.2B.B.6B2A9B$9.A.A2.A7.B5.4B7.4B44.BA4.A9B2ABA3B15.4B56.2AB.2A12.3B4.5B2A8B$9.A2.A15.B.2B8.4B43.BAB2.A.A8B2A4BA16.4B54.A.AB11.2A.2BA5.15B$10.2A11.A3.B.4AB.2A4.4B43.A4.AB.13BA.2B14.4B53.A14.A.2BA.A5.13B$22.A.A.8A2.A5.4B50.4B3.3BABA3B2A14.4B51.2A15.A2.BA.A2.13B$22.A.12A7.4B49.2B2AB3.2B3A3B2A15.4B68.A3.A.A.2A4.8B$19.2A.A.A9B2.3A5.4B50.2A4.7B.B17.3BA65.A.4A2.AB2A6.6B$19.2A.2A2.8B.A2.A6.3BA58.4B20.3BA63.A.A3.A.A2.B8.5B$22.A13.2A8.ABA59.2B22.3A63.A.A2.A2.2A.2A9.B.B$22.A.A4.2A16.2A150.A3.2A2.A.A9.3B$23.2A4.2A17.B158.A.A9.B2AB$208.A11.2A!

### Re: Execution of Old Guns by Variable-Speed Firing Squad

I tried to cut the new p4 bumper down by one more row, but there doesn't seem to be a small oscillator capable of replacing the eater. This is the smallest one I was able to find:

It seems unlikely that this will improve any guns.

Only the variant on the right appears in the gun collection at the moment. The variant on the left will definitely reduce some bounding boxes.

This should probably be considered the standard form of the p7 bumper:

The p3 eater trick can be used naively to reduce periods 14, 18, 21, 28, 29, 34, 42, 51, 57, and probably many higher periods. Period 50 is slightly less obvious:

### Re: Execution of Old Guns by Variable-Speed Firing Squad

The p3 eater and two more custom p3 sparkers cut two columns off the LHS and one row off the bottom of the p27 gun. They replace the two p9 bumpers on the LHS and the bottom left. On the LHS, the weld to the eater of the following bumper is not necessary, but reduces the size of the sparker within the new bounding box, so I left it in. I also replaced the snark on the RHS with the version from the LHS for no reason other than a slight population reduction.

Edit 2: p00414osc3 variable gun. Derived from p00402osc6. Uses another custom p3 sparker. I don't think it's possible to save the extra row on the LHS in this one using the p3 eater, and I also don't think the loop can be squashed down to 390. Improves p207, p219, p231, p438, p462 and p486.

Edit 3: In the same vein as p00405osc3, here is p00426osc3. The p3 sparker welded to the hive with tail I reused from somewhere, not sure if I had used it in one of the published guns though. When extended the usual p3 can be used instead. This is a reasonable improvement on the current p00402osc6 which is used for p213, p225, p237, p426 and p474. Unfortunately it can't be squashed down to p402, which is the only other period p00402osc6 was used for. [Edit: replaced custom sparker with a significantly smaller one. <snip comment about p75>. This could equally remain as p00426osc6, but I thought the osc3 version was more useful until I realised it was overclocked at p75.] #C p00426osc3#C compression = 78x = 66, y = 59, rule = LifeHistory20.2A11.A$19.B2AB9.A.A$20.3B9.A.A2.2A3.A$19.B.B9.2A.2A2.A2.A.A$19.5B8.B2.A.A3.A.A12.A$19.6B6.2ABA2.4A.A11.3A$19.8B4.2A.A.A3.A12.A$20.13B2.A.AB2.A11.2A$18.13B5.A.A2B.A7.5B$17.15B5.A2B.2A6.4B$17.15B4.3B10.5B$16.17B.B.2B10.6B.B$16.29B3.9B$15.13B2A16B2.11B.B$9.2A3.14B2A16B2.12B2A$10.A2.2AB3.27B.13B2A$10.A.A2.A4.39B.B$8.2A.A.2A5.6B3.B2.2B2.22B$7.B.A.A.A5.6B14.20B$5.B2A.3A.A4.9B14.20B$3.B2A.AB2.2A4.4B4.2A15.19B$2.2A.AB9.4B5.A15.19B$2.2B.2BA7.4B7.3A12.17B2ABA.2A$2.AB.2B7.4B10.A10.2AB.3B.11B2A.2A.A$.BAB3A6.4B21.A.AB6.11B$2A2B.B.B4.4B22.A8.10B$.BA2.3B3.4B22.2A7.10B$5.3B2.4B32.11B$5.BA6B33.11B$4.BABA4B33.13B$4.A2BA3B31.2B.13B.2B$3.2B2A5B29.21B$3.10B26.25B$3.6B.4B25.25B$.2AB.3B3.4B23.27B$A.AB2.B5.4B22.27B$AB11.4B20.29B$.AB6.2A3.4B20.27B$.3BAB2.A2.A3.4B19.6B2.11B2.6B$.2A.A.AB.2A5.4B17.A3B.B3.8B.B4.B.3BA$2.B.A.A2B8.4B15.BABA7.B.4B10.ABA$.3A2.A.B9.4B13.2B2A11.3B11.2A$A5.A.2A9.4B11.4B12.4B11.B$2A5.A2.A9.4B9.4B12.BA3B$8.2A11.4B7.4B12.BABAB$22.4B5.4B13.A.A2.2B2.B$13.A9.4B3.4B12.3A2.3AB.B2A$13.3A8.4B.4B3.A8.A3.2A2.BA2B2A$16.A8.7B3.A.A3.A4.3A2.2A.AB.B$15.2A9.5B4.A.A2.A.A5.A.A2.AB$15.4B7.6B4.A.2BA.A6.A.A$17.2A.A2.4B2A4B4.2B2.A8.A$16.BA.3BA.2BA2BA4B3.4A$17.B2A2BA4BABA3B3.B$18.A3.A4.BA3B4.3A$18.BA4B5.5B2.B2.A$19.AB2ABA7.2A.2BABA$22.BAB7.A.BABA.A.A$23.A9.2A5.2A!

I haven't experimented with adding semi-snarks to any of these guns yet. I guess that will also yield improvements.

Edit 4: Made a few small updates to correct the compression values in some guns (which I had misunderstood) and a population reduction for the p00426osc3.

Edit 5: Aargh, I really didn't understand the compression parameter after all and got completely confused by the overclocked syringe. Edited everything back (which hopefully no-one saw) and will post an improved overclocked p75 in the next post.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

Sorry about the mess of edits in my previous post. I spent far too long figuring out that there was little difference between using the p3 and p6 bumpers in the p402 and p426 gun families (and other similar families) as well as being confused by the overclocked syringe.
Here are a few more guns which are further variations on the current collection using the p3 bumper.

Replacing the p00402 in the existing p00402x2 gun family with the p00402 from the previous post gives a similar improvement. I left the p3 bumper in for this one, but it could readily use the p6 instead. Improves p804 which is the only period the old one was used for.

I hope I got all the annotations right. I've just interpreted how they're used in related guns and applied that to the new ones. Here's one more gun family using the p3 bumper to replace snarks - derived from the p00564 family (and other related guns). It improves p201, p531, p555, p579 and p603. In addition to p201, p177 was listed in the tentative guns but I can't make the glider crossings work at that period. p00531osc3 #C compression = 531#C tentative_compression = 78#C y_slack = 20#C y_trips = 2x = 70, y = 59, rule = LifeHistory39.2A$39.A.A$41.A4.2A$37.4A.2A2.A2.A$37.A2.A.A.A.A.2A$39.BABABA.A$40.B2ABA.A$41.2B.BA$40.3B7.A$10.B16.A3.2A6.4B7.3A$9.B2A13.3A4.A6.B2A3B8.A$7.B2A2.A.2A8.A7.A.AB3.B2A3B7.A.A$4.2A.4A5BA7.2A7.2AB.10B5.A.AB$3.A.2B.A.2BA2BA5.5B9.13B5.A3B$2.A.A2.2A2BA2.B4.BA3B11.14B6.4B$2.A.A2.A2.5A4BABA3B10.15B5.6B$3.A4.A.A.2AB.2BA2BA4B11.8B2.4B4.7B$7.2A.A.B2.4B2A4B12.6B5.4B2.8B.4B.B$6.A3.2A6.6B12.9B4.17B.B2A$7.3A8.5B12.4B4.2A5.18B2A$9.A7.7B10.4B5.A6.16B.2B$16.4B.4B8.4B7.3A3.16B$2A13.4B3.4B6.4B10.A3.15B$.A12.4B5.4B4.4B11.A.2AB.12B$.A.AB2.B5.4B7.4B2.4B10.2A.A.AB2.11B$2.2AB.3B3.4B9.8B11.A2.A5.10B$4.6B.4B11.6B14.2A5.2B2A6B$4.10B13.4B21.3B2A6B$4.2B2A5B13.6B21.10B$5.A2BA3B13.8B20.8B.B2A.A$5.BABA4B11.4B2.4B18.7B3.B2AB3A$6.BA6B9.4B4.4B17.6B6.B4.A$6.3B2.4B7.4B6.4B17.6B4.2A.3A$3.A2.3B3.4B5.4B8.4B16.5B4.A2.2A$2.ABA.B.B4.4B3.4B10.4B14.8B.A.A$2.A3BAB6.4B.4B12.4B4.A8.8BA.A.3A$3.2B.2A7.7B7.A6.4B3.3A6.6B.2BAB.A2.A$2.ABA.2AB7.5B8.3A5.4B5.A4.7B2.2B2.A.A.A$.A.2B2A2.A5.6B6.2A3.A5.4B3.2A4.7B3.B.2A2.A.A$BA.A2B4A4.4B2A4B2.B.A.2A7.4B2.4B.8B2.A.A2.A.A.A$.B2A.B4.2A.4BA2BA2B.BAB.A.A4.A4.4B3.11B2.2A2.2A.2A$2.4A.2A.A3.3BABA3B3AB2A2.A2.A.A4.4B.12B$2.BA.2A.A.A4.3BAB4.B2.3B2A2.A.A5.B3A12B$4.B4.A3.5B5.4A2B.B.2A.A7.A13B10.A$3.AB8.2A7.B2AB3A2BA.2A9.A9B11.3A$3.A.2A7.A8.2A.A2.2AB11.12B9.A$4.A2.A3.3A13.BAB12.16B6.2A$5.2A4.A16.A6.A6.24B$35.3A3.23B$38.A2.24B$37.A.B.24B$37.2A27B$35.2A2.A22B.4B$34.A2.3A3B3.2B3.B7.2B3.4B$35.A4.2B3.4B.3B5.BA2B3.4B$36.4A5.B2AB.B2AB4.A.A5.3BA$38.A7.2A3.2A6.A7.ABA$40.A27.2A$39.2A28.B! Here is p00531_9_p00201. This actually includes a saving of one column on the left hand side because it is possible to squeeze in the p3 eater. I don't know how this is managed in the gun collection, because the area is smaller than expected. I did notice that the get_area.py script uses the area of the gun from the confirmed folder and ignores the discrepancy with the value calculated from p00537osc3. x = 78, y = 59, rule = LifeHistory47.2A$47.A.A$49.A4.2A$45.4A.2A2.A2.A$13.B16.A14.A2.A.A.A.A.2A$12.3A13.3A16.BABABA.A$10.A2B2.B.BA8.A20.B2ABA.A$7.AB.A2B2AB2ABA7.2A20.2B.BA$6.A.2A.B.2A4B5.5B19.3B7.A$7.A2.4AB2.A4.BA3B12.2A6.4B7.3A$5.A.A2.A2.A3BA4BABA3B12.A6.B2A3B8.A$4.A.A4.A.A.2BA.2BA2BA4B11.A.AB3.B2A3B7.A.A$4.A2.4A2.A.A2.4B2A4B13.2AB.10B5.A.AB$3.2A8.2A6.6B16.13B5.A3B$9.2A10.5B17.14B6.4B$2A5.A2.A9.7B16.15B5.6B$A5.A.2A9.4B.4B17.8B2.2BAB4.7B$.3A2.A.A9.4B3.4B16.6B5.2B2A2.8B.4B.B$2.A.A.3A8.4B5.4B14.9B4.2A15B.B2A$.BA.A.BA.2A5.4B7.4B12.4B4.2A5.18B2A$.B3AB2.A2.A3.4B9.4B10.4B5.A6.16B.2B$.2A6.2A3.4B11.4B8.4B7.3A3.16B$BA11.4B13.4B6.4B10.A3.15B$A.AB2.B5.4B15.4B4.4B11.A.2AB.12B$.2AB.3B3.4B17.4B2.4B10.2A.A.AB2.11B$3.2BABAB.4B19.8B11.A2.A5.10B$3.BA2BA5B21.6B14.2A5.2B2A6B$3.BA2BA4B23.4B21.3B2A6B$4.B2A4B23.6B21.10B$4.6BAB21.8B20.8B.B2A.A$5.6B2A19.4B2.4B18.7B3.B2AB3A$5.3B2.2A2B17.4B4.4B17.6B6.B4.A$.AB2.3B3.4B15.4B6.4B17.6B4.2A.3A$BABA.B.B4.4B13.4B8.4B16.5B4.A2.2A$.A3BAB6.4B11.4B10.4B14.8B.A.A$2.2B.2A7.4B9.4B12.4B4.A8.8BA.A.3A$2.2A.2AB7.4B7.4B14.4B3.3A6.6B.2BAB.A2.A$2.2B.2A9.4B5.4B16.4B5.A4.7B2.2B2.A.A.A$3.A2B.2A8.4B3.4B18.4B3.2A4.7B3.B.2A2.A.A$5.A3B9.4B.4B20.4B2.4B.8B2.A.A2.A.A.A$6.A.2BA8.7B22.4B3.11B2.2A2.2A.2A$8.2A.A8.5B11.2A11.4B.12B$11.A7.6B6.2A.A2.A12.B3A12B$11.2A5.4B2A4B2.B.A.2A15.A13B10.A$17.4BA2BA2B.B2A.A.A4.A12.A9B11.3A$18.3BABA4B5A2.A2.A.A10.12B9.A$19.3BAB4.B2.A2B2A2.A.A9.16B6.2A$17.5B5.A2BA2B.A.2B.A3.A6.24B$17.2A7.A5B4A.2A4.3A3.23B$18.A8.2A.A2.2AB10.A2.24B$15.3A13.2AB11.A.B.24B$15.A16.B12.2A27B$43.2A2.A22B.4B$42.A2.3A3B3.2B3.B7.2B3.4B$43.A4.2B3.4B.3B5.BA2B3.4B$44.4A5.B2AB.B2AB4.A.A5.3BA$46.A7.2A3.2A6.A7.ABA$48.A27.2A$47.2A28.B! In a similar vein, it's possible to improve p507 with this version of the gun - squashed down to p507 by using another custom p3 sparker which adds two columns. I guess it constitutes a separate gun family, but it's never going to compete at any other period. #C compression = 507#C tentative_compression = 78#C y_slack = 17#C y_trips = 2x = 69, y = 59, rule = LifeHistory38.2A$38.A.A$40.A4.2A$36.4A.2A2.A2.A$36.A2.A.A.A.A.2A$38.BABABA.A$39.B2ABA.A$40.2B.BA$39.3B7.A$30.2A6.4B7.3A$31.A6.B2A3B8.A$11.A16.A2.A.AB3.B2A3B7.A.A$10.BAB13.3A3.2AB.10B5.A.AB$8.B2A2.A.2A8.A8.13B5.A3B$5.2A.A2B3AB2AB7.2A7.14B6.4B$4.A.2A.B.2B4A5.5B7.15B5.6B$3.A.A2.2A3B2.B4.BA3B11.8B2.4B4.7B$3.A.A2.A2.2AB3A3BABA3B10.6B5.4B2.8B.4B.B$4.A4.A.A.BAB.2BA2BA4B8.9B4.17B.B2A$8.2A.A.B2.4B2A4B8.4B4.2A5.18B2A$7.A3.2A6.6B8.4B5.A6.16B.2B$8.3A8.5B8.4B7.3A3.16B$10.A7.7B6.4B10.A3.15B$2.2A13.4B.4B4.4B11.A.2AB.12B$3.A12.4B3.4B2.4B10.2A.A.AB2.11B$3.A.AB2.B5.4B5.8B11.A2.A5.10B$4.2AB.3B3.4B7.6B14.2A5.2B2A6B$6.6B.4B9.4B21.3B2A6B$6.10B9.6B21.10B$6.2B2A5B9.8B20.8B.B2A.A$7.A2BA3B9.4B2.4B18.7B3.B2AB3A$7.BABA4B7.4B4.4B17.6B6.B4.A$8.BA6B5.4B6.4B17.6B4.2A.3A$8.3B2.4B3.4B8.4B16.5B4.A2.2A$5.A2.3B3.4B.4B10.4B14.8B.A.A$4.ABA.B.B4.7B12.4B4.A8.8BA.A.3A$4.A3BAB6.5B14.4B3.3A6.6B.2BAB.A2.A$5.2B.2A5.6B6.A8.4B5.A4.7B2.2B2.A.A.A$2A2.AB4AB3.4B2A4B2.A.A8.4B3.2A4.7B3.B.2A2.A.A$A2.A.2B.2A3.4BA2BA2B.AB.A10.4B2.4B.8B2.A.A2.A.A.A$.A.ABA2.AB4.3BABA4BA2B12.4B3.11B2.2A2.2A.2A$2.A6.2B4.3BAB4.A.B.B11.4B.12B$3.2AB2.ABA2.5B4.6B2A11.B3A12B$4.AB3.A3.2A7.B2ABA.2A12.A13B10.A$4.AB8.A7.2ABA2.A14.A9B11.3A$2.B2AB5.3A6.3A.2A.3A12.12B9.A$2.2A7.A7.A2.2B2AB3.A10.16B6.2A$.B2AB14.2A2.2BA.2A2.A2.A6.24B$.A.A18.AB2.A.3A3.3A3.23B$2.A20.4A10.A2.24B$27.2A7.A.B.24B$25.A2.A7.2A27B$25.2A7.2A2.A22B.4B$33.A2.3A3B3.2B3.B7.2B3.4B$34.A4.2B3.4B.3B5.BA2B3.4B$35.4A5.B2AB.B2AB4.A.A5.3BA$37.A7.2A3.2A6.A7.ABA$39.A27.2A$38.2A28.B! I think I might give the loop crossing guns a break from now on. Like dvgrn, figuring out all the permutations of different welds and sparkers to make things fit is giving me a headache. Edit: Sokwe's trick with the p3 eater to improve the p25 can shave off at least one row of the p50: x = 143, y = 109, rule =

### Re: Execution of Old Guns by Variable-Speed Firing Squad

I've been meaning to report this since I ran into it in late March. It seems I wrote it up as a lame annoying April Fool's joke, but then thankfully forgot to post it. See the quote below.

Now that it's not April any more, I'll report the actual problem first. With any luck that will be less confusing.

If I'm remembering right, my builder script has found only one problem so far with the guns currently posted on GitHub. The period 640 gun in the "variable" folder is actually period 512, and does not contain a period multiplier as the checkin note advertises. It would need a quinti-Snark and four signals to actually be period 128*5 = 640 ... but we don't have a quinti-Snark.

So that variable "p00640" is promising four guns that don't actually exist, and thus is artificially lowering our average bounding-box-size statistics (horrors!).

We can improve on the previous p640 record-holder somewhat by period-quadrupling a p160 gun. That gets us down to a 5376-cell bounding box, or maybe a bit lower if someone can weld the quadri-Snark in closer, but definitely not as low as 4774.

Below was my attempt at April-Foolsifying this bit of news:

On April 1, dvgrn wrote:I've found a way to greatly reduce the bounding boxes of a large number of guns in the current collection. The method is already used to reduce the size of the current p640 gun to 4774 cells. Without this trick, I think the stable p608 would win the competition, with a 96x59 = 5664-cell bounding box.

Start with any of the small guns with a relatively high period, like the p104. Quadruple the period by adding a quadri-Snark. So far so good.

But then -- this is the good bit -- the bounding box stays significantly smaller if you just pretend that the quadri-Snark is there, instead of actually adding one!

If it seems like extra gliders are showing up, just ignore them -- with luck they'll just fly off to infinity.

It's very strange, but it appears that nobody has thought to apply this same idea anywhere else. The same optimization method should work equally well for tremi-Snarks and semi-Snarks.

### Re: Execution of Old Guns by Variable-Speed Firing Squad

dvgrn wrote:If I'm remembering right, my builder script has found only one problem so far with the guns currently posted on GitHub.

Just for the record, the "builder script" is the script I've been working on that is supposed to automatically construct the full 14-999 gun collection based on the ceebo/glider_guns README. It can currently produce 876 guns. There are seventeen three-gun families left to make templates for, and about double that number of two-gun families, and then I'll be all done, finally.

-- Except now there are improvements from wildmyron, so I need a new edition of the README so I can tell what families are missing from my template folder, and which other families are in need of an update.

@chris_c, is there any likelihood of a README update getting checked in soon, or should I just dive in and try to incorporate the last few posts, and maybe take notes for you?
