Here is an unofficial update to the README from my local copy of the collection.

README.txt
Unofficial updated README
(31.58 KiB) Downloaded 51 times

I can probably make an updated collection available but it would have all the improvements and new guns in one commit. Hmm, I just remembered my local copy also has a number of trial guns that I made up but didn't provide any improvement, and that would probably confuse things.

Here's a diff between current and new README files

Thanks! I'm going to wait a while longer and hope for an official update, but this will definitely be helpful if I get desperate.

Meanwhile, I'm gradually closing in on the current version of ceebo/glider_guns -- the script now builds 942 guns successfully out of 986, with the correct bounding boxes for all of them.

Speaking of desperation, can someone (Weldbot?) please contribute the correct weld for Scot Ellison's p727 gun? I tried flipping the pi-to-G catalyst over ... but didn't actually break out JLS or anything sensible like that. Guess I wasn't _that_ desperate.

The thing is, I usually find after far too much staring at these things that chris_c was right after all. Is that true again here?

EDIT2:...Yup. Silly me, the output glider was just in the wrong place -- it doesn't have to guard that outlying spark from the pi-to-G in this case.

EDIT3: Finally done with scriptifying the current collection. This script builds all 986 guns, and tests all the variable ones to make sure bounding box and orientation are correct. Fixed guns and the dozen remaining cases with a suffix of "_variable0" aren't actually tested yet -- have to leave some refactoring for the 2.1 version of the script, along with wildmyron's README update. Too tired to tackle that just yet.

@wildmyron, the builder script is fairly happy with your variant of the README. There was a '"189 (4620, 'test')" that needed replacing. And then a bunch of the fixed guns seem to have been reduced, but the patterns weren't published -- right? Or was the new bounding box just calculated but the guns were never actually edited?

bad size 14 (61308, 'fixed'): really 61805
bad size 18 (16377, 'fixed'): really 16905
bad size 21 (28258, 'fixed'): really 28457
bad size 25 (15730, 'fixed'): really 15587

bad size 36 (2401, 'fixed'): really 2450
bad size 87 (3800, 'fixed'): really 3927

Then there's one "p00402osc6x2b_0" left, which I'm just renaming to p00402osc6x2 since there doesn't seem to be an "a" version to compete with it any more. And the three p640-based guns I mentioned a few posts back are promised to be smaller than they can actually be made:

bad size 320 (4774, 'p00640_0'): really 5664
bad size 324 (4914, 'p00640_1'): really 5723
bad size 340 (5494, 'p00640_5'): really 5959

320 and 640 I have as (5376, 'p00480x4_0'), and 324 is (5723, 'p00640_1'), unless someone can do better.

After that... well, there's still a dozen or so things to fix and new templates to build, but the script already runs to completion and builds all but 20 of the new guns:

Done.  Errors:

I think you need to update your repository - Chris updated most of those on 6/7 April. Your p25 is smaller than the one in the repository though - not sure what's going on there.

This gun (and the p00402osc6) are one of the cases that really confused me about which form to use and naming convention. I kept it as 'b' because the previous p00402osc6x2 is really a completely different gun (based on CC p6 reflectors). I hadn't done the same with the p00402osc6 just because it was one of the earlier ones and I hadn't yet realised that there was a mechanism for doing so. I wanted to leave it to Chris to decide whether those two guns should replace the old ones or if the old ones were worth keeping around in the way that other unused variable guns are (for inspiration, I guess?).

Some interesting stuff in this thread that I haven't had time to properly look at. I fixed the problem with the variable p640 though. Really it's a p512 and the error looks like it has been there for a good few years. With that correction I get the following new sizes:

+320 (5106, 'p00448x2_4')
+324 (5723, 'p00608_5_p00324')
+340 (5959, 'p00608_9_p00340')
+640 (4928, 'p00616osc8_3')


Anything else that needs immediate attention i.e. stuff that is blatantly incorrect?

Oh, I updated the p25 manually based on a posted pattern. Thanks, that all makes sense -- I'll patch things up from source in the next day or two.

wildmyron wrote:Are these messages relating to templates that haven't been built yet?

The missing guns are from unbuilt templates. The messages are mostly cases where the templates aren't good enough... the templates are designed to make adjustments in just one dimension, but a lot of guns need alternating adjustments in two dimensions, or occasionally even more complicated stuff. So those cases I just build manually as alternate ("alt") guns, and the script takes those instead of using the templates.

EDIT: Actually that's not right -- most of those messages were from improvements posted around here that I somehow didn't include in the package, though I was sure I had. Fixed in next posting coming along shortly, or at least sometime...

Very little. I only have two inconsequential things in my notes, besides the possibility of renaming "p00402osc6x2b" -- I'm not planning to update my script to understand letter suffixes for just that one case.

p00488osc8 and p00488osc8p2 have a p4 oscillator in them that might as well be p8:

And it says here that p00915osc5 has an unnecessarily large weld for the two eaters at the left -- the third welded eater isn't used.

EDIT: After the p640 and p63 checkin, these I think are all the guns that need to be added to the variable folder, or replaced in the fixed folder, to match wildmyron's README:

Good to know. I had indeed fallen a bit behind the times -- the much bigger old p4 sparker was still shown in the "p4 bumper" definition in the Life Lexicon (left, below). Have patched that up now.

Yup, sorry, I linked to the right places but typed the wrong text. Fixed now.

EDIT: Had to add a couple more guns to the "variable" folder to get everything to work right. Somehow I missed the improved p00402osc6 and p00402osc6x2 before.

Okay, I think everything is up to date now (until Kazyan shows up again with a quinti-Snark or a small color-changing Snark or G-to-2G or what have you).

The script is back to building 986 guns, and now the bounding boxes all match or improve on the estimates in wildmyron's README, except the p640-related ones of course.

A few more minor things cropped up:

bad orientation 493 (5037, 'fixed')
25 size should be (15587, 'fixed'): README says 15730
804 should be (4620, 'p00402osc6x2_0') -- wildmyron's README says 4680, which is one more column.
  -- currently checked-in README says 5112
402 should be (3584, 'p00402osc6_0'): wildmyron's README says 3640
  -- currently checked-in README says 3712
603 should be(4602, 'p00531osc3_9'): wildmyron's README says 4661
  -- currently checked-in README says 5400

Guns built=750, fixed=227, from var folder=9
-- total=986


Now if I can just convince chris_c to check in new templates in parallel with new guns, my troubles will be over! I do have a little refactoring to do in the script, as can be seen by the various TODOs, so a version 2.2 will be along eventually. It's currently my usual unreadable procedural-programming mess.

I kind of think the upper limit of the collection should be period 1024, though, not period 999. That way the collection would have over a thousand guns in it. I mean, if we're going to stick strictly to three digits, what are those two leading zeroes for in all the gun names, anyway?

Here's the full report from running v2.3 of the script against the checked-in README as of 6/1/2018. Looks like all the remaining problems are guns that are smaller than the README predicts -- a good problem to have!

Errors:
bad size 25 (15730, 'fixed'): really 15587
bad size 27 (22144, 'fixed'): really 21717
bad size 75 (4640, 'fixed'): really 4278
bad size 402 (3712, 'p00402osc6_0'): really 3584
bad size 426 (4087, 'p00402osc6_3'): really 3953
bad size 534 (4189, 'p00534osc6_0'): really 4130
bad size 558 (4366, 'p00534osc6_3'): really 4307
bad size 582 (4543, 'p00534osc6_6'): really 4484
bad size 606 (4720, 'p00534osc6_9'): really 4661
bad size 804 (5112, 'p00402osc6x2_0'): really 4620
Guns built=745, fixed=230, from var folder=11
-- total=986

The attached archive has all the better-than-expected guns in it. I don't think my script is misreporting any gun sizes.

gun-builder-script-1June2018.zip
Simplified and cleaned up version 2.3 of builder script, plus the same gun collection as before

I've addressed most of the TODO items, so among other things the script now reads from the full copy of the README. To run the script against the latest data from Github whenever that gets updated, download the current ZIP archive and extract it to a glider_guns-master folder on the same level as the template and the output guns folder. For a clean rebuild, delete all the files in the guns folder before running the script.

I added a missing-guns readout to the error display, so that if the README gets updated and some templates haven't been built and added yet, a list will appear showing the remaining missing periods that need some attention. That won't work unless you empty the gun folder before rebuilding, though -- the script is happy as long as there are 986 gun files in that folder with the appropriate p00nnn... names.

@dvgrn I made a push that hopefully deals with those discrepancies. I think you are underestimating the size of the new p402osc6 though (because of the Unix maybe?). Also the next step in that family, p402osc6_3, is suboptimal since there is a new p426osc3 given by wildmyron. I couldn't resist adding that one. I will attempt to work out how far I still am behind wildmyron's README a bit later.

EDIT: Pushed another commit to address the minor points in dvgrn's message. I suppose we agree everywhere now?

Right you are. There are sparky overflows on two sides of two of those templates. I marked the overflow on the right but didn't see the left one.

Will have to bump the script up to 2.4, and see if I can catch cases like this where the template is built incorrectly. At the moment it only warns you if a glider doesn't escape from the bounding box at the time that it's supposed to.

I'll throw in a p426osc3 template while I'm at it -- thanks for the heads-up! EDIT: Oh, did that already -- never mind...

chris_c wrote:I will attempt to work out how far I still am behind wildmyron's README a bit later.

If you're getting the same bounding box numbers that my script is reporting, I think you may be caught up with wildmyron's README, or even maybe a little ahead in some areas like the p640 family.

EDIT2: A quick re-run of my script against the current README, with those p402 templates fixed, only two errors showed up. I had repaired these in my local copy of the fixed guns but may not have told anybody about them:

Errors:
no escape 141 (3782, 'fixed')
bad orientation 493 (5037, 'fixed')

Guns built=748, fixed=227, from var folder=11
-- total=986

Everything else seems to match now (!) ... except I keep having to remove the 'b's from p00861osc7b_*. Could that name possibly be changed? I just don't feel like making my script understand letter suffixes, for that one case.

I added 8 new variable guns by wildmyron and hopefully I am up to date now. Also I addressed the minor points in dvgrn's last post. Average size has dropped by 10 cells:

Looks really good! After dropping in the latest version of the whole collection from GitHub, I only had to fix one template and add one more, and the script gave me this result:

No apparent problems, just a silly suggestion.
For version 2.5 of the script I'll add a second folder and drag a copy of all these long-suffering guns back into LifeHistory format again -- they're a lot easier to understand that way. Basically just have to keep running {period} ticks at a time and clearing outside the bounding box, until the cell count stops increasing.

Looking at your gun script for the first time I have a couple of comments:

1. Every gun with more than one direction of adjustability need a new RLE file for every extension. Sounds like a bit of a maintenance burden but I suppose time will tell.

2. Quite an obscure comment and I only noticed this because I made the adjustment myself today. p00507osc3alt3 is not the minimal form of p00507osc3_3. It is merely the minimum form of p00507_3 that allows crossings at p177. As such, shouldn't it go in as a "specialcase".

EDIT:

3. Are you verifying that every gun has the correct period and checking the bounding boxes by actually evolving the pattern in Life? If so it is nice that all of our data is in agreement when my way is just doing some additions and multiplications.

Thanks! That gives a little new territory to play around with -- I'm kind of hoping that a few semi-Snark/semi-cenark tricks will work, with a track that alternately follows two different paths.

Period 1024 is at most 3430:

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

1. Every gun with more than one direction of adjustability need a new RLE file for every extension. Sounds like a bit of a maintenance burden but I suppose time will tell.

Absolutely true. On the other hand, the work is all done as of right now, and my goal was to get back to having a downloadable collection with all the latest guns in it. There's really no way to do that without solving all those custom adjustment problems, once. Now at least there's a place to put those solutions, instead of losing the details so that someone has to figure them out again whenever they happen to need that particular gun period.

chris_c wrote:2. Quite an obscure comment and I only noticed this because I made the adjustment myself today. p00507osc3alt3 is not the minimal form of p00507osc3_3. It is merely the minimum form of p00507_3 that allows crossings at p177. As such, shouldn't it go in as a "specialcase".

Probably. I'm looking at whether it makes sense to just take out the "specialcase" subfolder for version 2.5, though -- just piling everything into the template folder and adding a "specialcase" label to the filename seems maybe a little simpler.

chris_c wrote:3. Are you verifying that every gun has the correct period and checking the bounding boxes by actually evolving the pattern in Life? If so it is nice that all of our data is in agreement when my way is just doing some additions and multiplications.

Yes! As you discovered, though, my gun-testing code isn't foolproof yet. It doesn't notice edge sparks sometimes, and you can very easily fool it with a fake fixed gun, or (less easily) with a fake template. For example, the 2.4 script thought that this was a fixed p14 gun -- quite a big size improvement!

x = 7, y = 6, rule = LifeHistory
2.A$A.A$.2A$5.A$6.A$4.3A!

Mostly if a template fails the script will just go into an infinite loop -- it keeps adding input cells at the right times, but never sees output cells where it wants to see them, so it just keeps trying. I haven't bothered to write any tests for that situation, since you can just cancel the script and hit Ctrl+R to see what's failing.

For 2.5 I'm appending a check, after the re-conversion to LifeHistory is done, to make sure that all the cells are in the exact same places after the gun is run for a cycle. Just check in your README for guns up to 1024 when you get a chance, and I'll test against that and (eventually) post a script that builds all 1000+ guns.

EDIT: Slightly more robust testing code turned up a few more minor issues with the existing collection. The p00380osc15x3 variable gun is advanced four ticks too far -- there aren't actually any sparks from the filter oscillator that extend out into that row.

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

The p3 eater trick can be applied to the syringe:

Obviously, this will reduce a large number of guns slightly. I applied this and a few other reductions to the periods below 78:

Oh no! Another big decrease in population optimality, in the obsessive quest for bounding-box optimality...

Yes, you just have to grit your teeth and cut the bounding box down, no matter what the cost in elegance.

In Jason Summers' old gun collection, which was really Dieter and Peter's old old gun collection, there was a similar very common ugliness. One often had to save a column at each edge of a Herschel loop by replacing an eater with a boat-bit-catching snake -- the boat bit doubles the period (ugh) and the average population goes up by 2.5 (double ugh). A lot of the high-period primes used to be two Herschels going through a 180-degree symmetrical loop, which often had to have boat-bits on some of the edges.

It's funny that the boat-bit-catching trick is now (almost?) nowhere to be found in the gun collection. I had a quick look through but didn't find any examples. There's nothing much left that's big enough to have extra gliders to suppress any more.

The most prominent example is the small p120 gun:

I think this is unlikely to ever be reduced further.

Hmm... how many of the guns in this collection are true-period guns? Because the last few examples posted don't seem to be.

I think the Life Lexicon is up to date on this:

True period n guns are known to exist for all periods greater than 61 (see My Experience with B-heptominos in Oscillators), but only a few smaller periods have been achieved, namely 20, 22, 24, 30, 36, 40, 44, 45, 46, 48, 50, and 54 through 61. See also Quetzal for the 54-61 range.

Many but not all of the known true-period guns are the smallest known guns at their period, the biggest exception being the Quetzals. So you'd mostly just have to look through the dozen periods listed and count up the ones that are actually true-period, and also check the range up to p78 where syringes start to work.

Pretty much everything above that is true-period. There may be a few weird exceptions. I ran into an oddball odd-period gun yesterday where two eaters had been welded into a test-tube baby, doubling the period. But the remaining cases with boat-bits, like the p00960, are even-period anyway.

The builder script runs without errors now when dropped (with its associated folders) into an unmodified copy of the latest content from ceebo/glider_guns on GitHub. Ah, except I did put in a smaller p1024 gun and hand-edited the README accordingly:

1024 (3430, 'fixed')

There are three dozen fixed guns in the attached archive file, where for one reason or another the LifeHistory version of the pattern didn't quite match what you get by running the gun until the live cells all match up again. That test is now done for all the fixed guns, so I think that with this patch the collection will now be pretty well standardized.

Done.
Guns built=775, fixed=228, from var folder=8
-- total=1011

The script will create 'guns' and 'LHguns' folders and populate them with guns with every period in the range from 14 to 1024.

As the README is updated and new templates are needed, the script will report missing periods... or in some cases it will go into an annoying infinite loop that you'll have to hit Escape to get out of, if a template doesn't behave as expected at a particular adjustment. Use at your own risk.

EDIT: It's kind of silly to make everyone run the script, I guess. Here's the current collection that the script produces. If anyone finds problems (that aren't in the GitHub version of the guns) please let me know.
