(Also, how would I submit this to Catalogue? Sorry that I'm new to stuff like this.)

(Also, how would I submit this to Catalogue? Sorry that I'm new to stuff like this.)

That can be done using the form at the end of the page https://catagolue.hatsya.com/syntheses
Currently it says this:

The RLE must be two-state (plain B3/S23);
Pattern cannot exceed 9999x9999, 100000 live cells, or 400 kB;
Distinct components in the pattern must be separated by at least 20 blank columns or rows;
Every glider in a component must have started interacting before time 1000, and finished interacting before time 4000.

See also the tutorial Tutorials/Glider_syntheses#Submitting_syntheses_to_Catagolue.

It kind of surprises me that triple pseudo still life and quad pseudo still life don't seem to have syntheses in sjk. It looks a little difficult, but I bet a converter-based synthesis is possible.

I synthesised the triple pseudo still life (76 gliders):

I'm thinking the best bet currently would be chris_c's spark_search, or possibly gencols with a bunch of clever filters added.

At one point I got part way through coding up a post-processor filter (also in Python) for the output of the octohash search scripts, but dropped it a few months ago and haven't had time to pick it up again.

The post-processor would orient all of the octohash outputs the same way and have them all produce the output on the same tick -- and some "envelope" cells could be added around the input object, to exclude recipes that would fail to work in a given context.

EDIT: just tried spark_search with various inputs along these lines -- 3g (S), 3gb (SE), and s2g (S and SE) gave no results on an 8-tick search, unfortunately:

Code: Select all

x = 49, y = 11, rule = LifeHistory

44.2A!

It's always possible that I did the setup subtly wrong, though, so independent verification might be good. I was a little surprised to get no hits at all, not even unworkable ones.

Without the domino spark at generation 20, a longer induction coil on the left would temporarily form before collapsing. Is it salvageable?

This still life looks similar to Cthulhu.
Now I'm working on component-based syntheses of big natural still lifes. I have an idea to synthesize all natural (C1 and G1) still lifes (although this can be difficult to achieve because Catagolue users are constantly finding new still lifes, especially TechnobladeNeverDies).

(I don't have the octohash database available from this computer. Here's hoping somebody eventually decides to host a really big, and extensible, octohash-type search utility somewhere online!)

Here's hoping somebody eventually decides to host a really big, and extensible, octohash-type search utility somewhere online!

I myself think a "generate, test, filter" search program would work better, when there are multiple different requests and filters that could be combined. It would be slower (since it would recompute constellations and evolve collisions each time), but it would need much less space, and it would work offline. Precomputing and storing all plausibly-interesting searches is going to become unfeasible.

I myself think a "generate, test, filter" search program would work better, when there are multiple different requests and filters that could be combined. It would be slower (since it would recompute constellations and evolve collisions each time), but it would need much less space, and it would work offline. Precomputing and storing all plausibly-interesting searches is going to become unfeasible.

Certainly that's true in some cases. On the other hand, we already have spark_search and QuFince, not to mention gencols.

The current octohash databases add up to about four and a half million collisions, so if I'm doing the math right (I might not be) ... that's just about one gigabyte of raw data -- 256*9*4500000. It takes something like 30 seconds with the current search algorithm on a good computer, to find all the matches in one gigabyte of data.

YouTube is currently storing, in the cloud, somewhere around 2,500,000,000 gigabytes of data, any piece of which can be retrieved fairly quickly by going to the right URL.

An online octohash database could search a hundred times as many collisions as we have fingerprinted so far, at least a thousand times faster than the octohash scripts currently do it -- at the cost of making the data stored on the server between 100 and 1000 times bigger. That just requires adding indexes. I haven't really scoped out how good some kind of SQL database would be at this kind of trick, but this is exactly the kind of thing that SQL databases are designed and optimized for.

A hundred times the current octohash search space is a lot better than we have now -- and it's totally doable with existing technology, even for a server hosted on somebody's laptop and made available only when it's convenient. Inevitably there definitely is always going to be some level of search that's unfeasible to do this way -- but at the same time, there's a much larger "octohash-reachable" search space that is actually very easy to set up.

Trying to work through all of that much larger octohash-reachable search space with a "generate, test, filter" approach would not just be a little bit slow; it would be unworkably slow -- like, weeks or months for each individual search.

The great advantage of the octohash approach is that you really only have to do those weeks or months of "generate, test, and filter" once -- and then record all of the generated data in octohash form, somewhere that has a lot of storage space. Storage is cheap; people's time is expensive, when a single search is eating up multiple days' worth of it.

To get closer to the topic of the thread, what is the best existing approach to find a way to put a block into the red location?
Wing does not work (if it is moved one cell down, then it collides with two yellow blocks). I looked through G-to-block/H-to-block factories and did not find anything compatible.

The octohash database search yields 14649 matches for a single block. Some of them might work in this context, but I did not look through all of them.

To get closer to the topic of the thread, what is the best existing approach to find a way to put a block into the red location?
...
The octohash database search yields 14649 matches for a single block. Some of them might work in this context, but I did not look through all of them.

QuFince might well be able to help, I think. Another standard way to tackle this kind of problem is to ask slsparse if it can push a block into that location. I don't have slmake set up properly on my current laptop, but I _think_ that something like this would probably produce a solution if there's something known in slmake's database:
