Not for me, it didn't.

What are the maximum computational budget for the pattern identification tool? The first 80c/1290d, with minpop 34 and maxpop 3507, fails to repeat, but is recognized by the apgcode tool. The second 80c/1290d, with minpop 31 and maxpop 280, works fine.

Is there any way to find or generate a list of objects which have occurred naturally in C1 and/or G1 for which Catagolue does not have any syntheses?

A script with a web scraper will do it, but just be aware that it will use server resources.

If someone decides to make this I'd highly recommend just downloading the C1 textcensus and Shinjuku and write some code to interpret and compare the data. It'd be much faster and less resource intensive than a web scraper.

Am I correct is assuming that there's no API to Catagolue hidden away? I would like to get the Glider Constructions for a large batch of objects, and right now it looks like I need to call up each one's page using the HTTP call: "http://catagolue.appspot.com/object/<apg>/b3s23" and then parse the RLE out of the response HTML. Just one -time requests as I'm updating my constructions database and making sure it's all up-to-date.

Yes, you need to request through an URL, but you don't need to get to the object page. Instead, you can obtain the syntheses URLs in the following format:
https://catagolue.hatsya.com/textsample ... /synthesis

It does not contain HTML (it's just plaintext), so you can directly obtain the synthesis RLE from that page.

Doesn't seem to work:

All of the syntheses are in https://gitlab.com/parclytaxel/Shinjuku so you can clone that repository instead. It actually gives you more information, because multiple alternative syntheses can exist in Shinjuku, whereas Catagolue only displays the lowest-cost synthesis for an object.

and then another time posting a cost improvement for the same still life. (This is a stage in the construction of a now-outdated larger spacefiller seed constellation.)

It sounds like now isn't really a good time to do any testing, though -- we can afford to wait until the readsynth queue is less overloaded.

Posted: **June 8th, 2023, 9:10 am**

Is there any way to change one synthesis to another of the same cost, and/or to make a continuous synthesis incremental, on your end? There's a handful of syntheses which are rather ridiculous and could be simplified for clarity. For example, this hivenudger backend pseudo-spaceship has an absurdly spacious continuous synthesis:

Code: Select all

x = 162, y = 95, rule = B3/S23
59bo85bo$57bobo83b2o$58b2o84b2o46$18bo$19bo2bobo$17b3o2b2o$23bo4$20b3o
$20bo$21bo30$142b2o$142bobo$142bo!

It'd be much better if it could be made into a two-step synthesis, one for creating the initial LWSS and a second step as follows for adding the second one.

Code: Select all

x = 20, y = 17, rule = B3/S23

Posted: **June 8th, 2023, 11:16 am**

It appears that all of the syntheses which include a Spaceship are spread out like that.

Yeah, the way that *WSSes are automatically replaced in Catagolue is not my favorite feature -- the gliders making the *WSS are just dropped in at some over-conservative safe distance, rather than the system hunting for something more compact, like the last possible time for the *WSS synthesis that still works.

Ordinarily Catagolue will prefer a two-stage synthesis over a single-stage synthesis, but that doesn't apply when the intermediate object is a spaceship.

If I remember right, it's possible to submit a recipe to Catagolue that includes *WSSes, but Catagolue will automagically do one of these ugly oversized replacements. This is basically why I've developed the habit of always doiong the *WSS to gliders conversion myself before submitting to Catagolue.

I don't know of an easy way to replace a synthesis already uploaded to Catagolue, with another "better" synthesis of the same cost. I'd love to have a button or something in the online GUI that could mark a single synthesis for deletion, in preparation for re-upload... maybe it could be a peer-reviewed or moderator-reviewed system, and/or could only allow a dozen or so so that nobody can maliciously delete piles of good syntheses.

Posted: **June 8th, 2023, 2:42 pm**

I should also point out that the final step for the synthesis of the following p27462 was also rejected because of some "invalid component" error (see line 1120 in the most recent job as of posting):

Would it be possible to have Catagolue selectively prefer incremental syntheses over continuous syntheses if given both, provided the costs are the same?

If it happens, no big deal, of course, but it seems worth making the request.
Catagolue uses Shinjuku's prefer_long option. So whenever the synthesis is regenerated (which happens whenever there's a material improvement), it will choose the one with the maximum number of stages.

For me it looks not mysterious, but offensive.
1. If Catagolue won't accept such optimization, then no need to mention such restriction, because people will just see result once they submit optimized version.
2. If it will accept, but someone think it is wrong, then correct way is to force fixing of #30 somehow. But that's a social problem, not technical, so I can't say much about how to do this.

Regardless of the existing Catagolue bugs, it is interesting and useful to know the traditional guidelines for measuring and formatting glider guns. This also includes the possibility of adding sparks or objects to indicate the correct bounding box of the gun, and people were adding such objects even before Catagolue existed.

I didn't knew it was tradition, thanks for explanation.

But anyway, I think extra junk does more harm than good.
First of all, it is not the part of the gun, so it is natural to want to optimize it away.
Second, it is easy to forget to remove this junk while combining gun with other components. But it is not easy to get rid of it once it is uploaded (another problem, which no one was interested to solve when I mentioned it).

upd: State 2 cells of LifeHistory allow to mark bounding box and at the same time they disappear during conversion to Life rule.

Only if you know how to convert correctly from LifeHistory to plain two-state B3/S23. Otherwise, simply pasting a LifeHistory pattern into a two-state layer will cause unintended effect, and changing the algorithm to QuickLife/HashLife via the menu item will also cause unintended effect.

I think it is best to keep the formats simple. Multistate extensions are sometimes nice for those people who are familiar with them, but otherwise, so far the plain two-state RLE is the best pattern exchange format I know about. It is a reasonably simple format, and it allows to share the patterns.

The idea of putting sparks or objects to indicate the bounding box or otherwise add some kind of metadata is also simple and it works. (For another example, check the old oscillator stamp collection, in which oscillator periods are denoted using digit-shaped still lives.)

Posted: **December 2nd, 2024, 1:28 pm**

Teaching people how to press Alt-J in Golly should not be that hard, right?
For me it looks easier than explaining why junk in the corner may be important.
If other software can't provide similar experience, it should be easy to implement such conversion.

Also components in LifeHistory format are easier to recognize:
Reaction history gives them well distinguishable and memorable shapes.
For example, it is easy to guess that glider goes in and out on the left, but not so much on the right.
