xs12_0j96z346 (long³ integral) also has a 7G synthesis now:

Code: Select all

x = 101, y = 31, rule = B3/S23

Ripped from 5Glider_stdin (TL+blinker+B), simplified and a 1G cleanup tacked on.

EDIT: xs12_31eg8426 (cis-long² hook with nine) in 6G from 5Glider_stdin (pi+blinker+G) with 1G cleanup:

xs14_09fg4cz321 in 6G (Down from 9G):

Code: Select all

x = 91, y = 91, rule = B3/S23

The improvement doesn't come from the usage of the 4G_stdin collision (Both syntheses use this exact glider-collision), but from a massive improvement on the cleanup process (To clarify, the previous synthesis took out the B-heptomino in 2G and the ash-cloud in 3G).

I have not found synthesis for this still life on Catagolue. Is this really the first known?
Nice work. In general, if Catagolue doesn't have a synthesis of an object, the chances are that that object hasn't been synthesized yet. I do have several improvements to list, though.
  1. Stage your syntheses: To stage a synthesis means to divide it into multiple parts. In general, it's a good idea to stage syntheses as much as possible without increasing the total cost. There are several reasons for this.
    1. Automated improvements: When a staged synthesis is uploaded to Catagolue, Catagolue does not interpret it has a single synthesis but instead as a chain of ways to get from one apgcode to the next. For example, Catagolue would view your non-staged synthesis as a way to get from a vacuum (xs0_0) to xs29_8e1t6gzwqb0t552zx11, while in the following staged synthesis, it would view the first step as a way to get from a vacuum to a block (xs4_33), the second step as a way to get from a block to the constellation xp2_033ze, the third step as a way to get from the constellation xp2_033ze to the constellation xp2_6952zy1ooy1e, etc…

      I have submitted that synthesis to Catagolue, but I know that once Catagolue updates, it will not use that synthesis of the constellation xp2_033ze because it already has a three-glider synthesis, which can be viewed at its Catagolue page. (In fact, one doesn't even have to include a synthesis of the initial constellation as long as one has verified that Catagolue already has a synthesis of that constellation, which can save a little time.) This makes the synthesis of that constellation and every following object, including the final object one glider cheaper. This would not have happened had the synthesis not been staged. There's also a program that can search for more efficient cleanups of constellations, but these only work when the cleanup is in a separate stage from the region stage that makes the final object, and it's better when the cleanup is staged as much as possible (without making it more expensive).
    2. Manual improvements: In addition to staging a synthesis making it easier for automated programs easier to find improvements, staging a synthesis also makes it easier (or at least more convenient) to make manual improvements. One of the reasons for this is because one only needs to submit the improvements for the relevant stages. As long as the synthesis is staged, if one finds an improvement to building the base constellation, one doesn't need to submit the cleanup again, and vice versa. Also, if the synthesis is staged, it's easier to analyze what's happening and see where improvements can be made. Syntheses that have been staged tend to be easier to for people to understand than syntheses that are all in one step. This is because in the latter type of synthesis, three or more things can be happening at the same time, and at the beginning, the entire pattern consists of a jumble of gliders at each corner, and it often isn't obvious which glider does what. The latter fact makes it more difficult to make improvements because if one wants to replace one glider with another (such as in order to reduce the cleanup cost), it may be difficult to figure out which glider to change the timing of, and the new glider may turn out to cross paths with another glider that could have been in a different stage, and sometimes trying to change the timing of that glider will cause more problems, either because one couldn't figure out which other gliders in the jumble of gliders at each corner had to be synchronized with it, so one re-timed the wrong gliders, or because one of the re-timed gliders now crosses paths with a glider from a step that could have been put in a third stage, etc….
    3. Individual playback: I originally didn't stage my syntheses, and one of the reasons that I opted to change was because there were several times where I wanted to look at a particular part of the synthesis, but it was taking a while to get through synthesizing the base constellation, and if I sped up the playback speed, I would typically miss the part that I wanted to look at. This doesn't happen when the synthesis is staged because each stage is done separately and can therefore start right away instead of having to wait for previous stages to occur.
  2. Clean up regions when they're small: It's easier to delete a region when it's small then after it has caused a large explosion. One example is when I deleted a pi-sequence with a single glider very early in its evolution instead of letting it create a large mess before beginning cleanup.

    Code: Select all

    x = 8, y = 5, rule = B3/S23
    o$b2o$2o$4b3o$4bo2bo!
    Also, in this example, notice how I cause the active region at the top to settle into a ship instead of letting it become a big mess.

    Code: Select all

    x = 47, y = 76, rule = B3/S23

    o$12bo23$45b2o$44b2o$46bo!
  3. Only synthesize the relevant parts of a constellation: I noticed that at least one of your syntheses created some objects in the base constellation that were not necessary for the final object. It's a good idea to avoid this because it unnecessarily increases the glider cost. If you're unsure about whether or not an object is necessary, you can try removing it and seeing whether or not the reaction still works or observing the active region after it interacts with the object, tracking the active regions that the interacts with, etc…, and seeing whether it affects the final object by the time that it's made. Also, sometimes an object only serves as cleanup, in which case it can typically be replaced by a glider.
  4. Try to use gliders as directly as possible: I noticed that one of your syntheses used a LWSS for cleanup. In general, you want to try to avoid doing this because LWSSes require three gliders each, and cleanup can typically be done more efficiently by using gliders directly. For example, here's a two-glider cleanup of the same constellation:

    Code: Select all

    x = 53, y = 15, rule = B3/S23
    7bo$6bobo$6bobo36bo$7bo36bobo$4bo39bobo$4bo40bo$4bo$2o$2o2$50b3o$50bo
    $7b2o42bo$6b2o$8bo!
    Also, if an object is only necessary for cleanup or a brief interaction, try to see if it can be replaced with a glider.
  5. Keep an eye out for fast components: Sometimes, if the object is formed with enough clearance, one can use a fast component to modify the object formed slightly. You should try to do this when possible because fast components are often more efficient than their slow equivalents. Here's an example:

    Code: Select all

    x = 215, y = 75, rule = B3/S23
    2bo$3bo$b3o$79bo$78bo$78b3o$bo$2bo$3o36$44b2o$43bo2bo81b2o5bo$43bobo82b

    2o5$158bo$157b2o$157bobo!
    The synthesis of the base constellation is included with the synthesis of the object without the fast component farther down in this post. I've attached a collection of fast components to this post for you to look at.

A few more advanced tips:
1 Check if you're improving a previous synthesis, or creating a new one. If you are creating a new one, it's fine to synthesise everything as lazily as possible, with the first thing that works. If you're improving a previous one and you can only get it close to the record, try looking at more advanced techniques such as using scripts to find syntheses.
2 If you have a bunch of stable ash to clean up, please clean everything up in one stage, instead of meticulously separating every glider (like M&C's example where they clean up the three ash objects in two stages). It just looks nicer if your content-including steps aren't squished by your cleanup. As well, if there's a large constellation to build, it's okay to condense it into fewer stages.
3 Try not to get too frustrated by synthesis tools, this can be pretty hard. (In particular, synthesise-patt and fast components generally have the most potential to give wrong results.)
4 Ask for help if you need any.
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

Nice work. In general, if Catagolue doesn't have a synthesis of an object, the chances are that that object hasn't been synthesized yet. I do have several improvements to list, though.

Overall, I'd say that you're catching on quickly, and you also seem to have a knack for finding good cleanups manually (although you should be aware that there are programs for that). Keep up the good work.

Also, one of your syntheses was invalid because one of the gliders used in synthesizing an R-pentomino would just barely hit a beehive if it tried to come from infinity, so I submitted a version that uses another three-glider synthesis of an R-sequence.

To assemble the above synthesis, I used the second 4G_stdin collision (2G TL+G, interrupted by two additional gliders) in conjunction with a carefully-placed cleanup glider... Nothing out-of-the-ordinary there! :lol:

The soup-based method is still an improvement—albeit by one glider instead of three—but I've submitted the above to Catagolue just in case transfer.py turns out to find it useful for anything.
