[calcyman]

Very impressive! I'm running those 6939 syntheses through (a modification of) mniemiec.py to assimilate them into Shinjuku. This necessarily will result in an improvement, because Catagolue only knows how to synthesise 6923 of the 17-bit still-lifes in <= 16 gliders.

Thank you so much!

[Freywa]

My base of syntheses of 6939 syntheses meets conditions 17 in 17:
138 meet conditions 17 = 17:

I'll not bore over your files for a while, but for compatibility's sake, don't use RAR. Use 7-Zip (or .tar.gz, or just plain old zip) instead.

Golly can't open 17-490.rle – you are definitely using a non-standard program to write your RLEs. They look fragmented when I open them up in a text editor.

Lastly, regarding the manner in which you presented your syntheses, an RLE file by itself is quite hard to analyse for the steps. I created Shinjuku and its format to fill in that gap – and now it contains tens of thousands of directly machine-readable components. I would appreciate it if you just give component lines in the future.

[calcyman]

(criticisms)

Bob: I found the files to be perfectly comprehensible, so please continue sharing your work in whichever format is most convenient for you. The automated conversion of archives of RLEs into Shinjuku lines is near-perfect (occasionally it has hiccups, but they're sufficiently rare that they can be done manually if necessary).

Interestingly, most of the syntheses agree with existing ones; out of 9981 synthesis components extracted from Bob's files, only 3265 are new.

[calcyman]

EDIT: a more up-to-date version of the script is in the Shinjuku repository

I've hacked together a lifelib script called findpreds.py (based on Jeremy Tan's pullsoups.py) which should be useful for eyeballing predecessors of natural still-lifes. It does the following:

• Downloads soups from Catagolue.
• Determines the first generation in which an isolated copy of the still-life is present (provided it's after gen 50).
• Rewinds that snapshot by 50 generations.
• Systematically deletes as many kingwise-connected components as possible whilst still ensuring that the still-life is still produced.

Code: Select all

import sys, os, lifelib

lt = lifelib.load_rules('b3s23').lifetree(n_layers=1)

zero = lt.pattern()
sl = lt.pattern(sys.argv[1])

sym = 'C1'
if (len(sys.argv) >= 3):
    sym = sys.argv[2]

rew = 50
if (len(sys.argv) >= 4):
    rew = int(sys.argv[3])

def contains_sl(mess):

    without = mess.replace(sl, zero, halo='ooo$ooo$ooo!', orientations='rotate4reflect')
    return (mess != without)

mosaic = lt.pattern()
for (n, soup) in enumerate(sl.download_samples()[sym]):

    s50 = soup[rew]

    lb = 0
    ub = 32768

    if contains_sl(s50[lb]):
        continue
    if not contains_sl(s50[ub]):
        continue

    # Binary search:
    while ((ub - lb) > 1):
        mb = (ub + lb) // 2
        if contains_sl(s50[mb]):
            ub = mb
        else:
            lb = mb

    print('#C soup %d gives birth at time %d' % (n, ub + rew))

    pred = soup[ub]
    comps = pred.components(halo='ooo$ooo$ooo!')

    for c in comps:
        if contains_sl((pred - c)[rew]):
            pred -= c

    mosaic += pred(n // 10 * 100, n % 10 * 100)

print(mosaic.rle_string())

For instance, if you run the following:

$ python findpreds.py xs17_0g8im853z343

then it yields this output:

My base of syntheses of 6939 syntheses meets conditions 17 in 17:
138 meet conditions 17 = 17:

I'll not bore over your files for a while, but for compatibility's sake, don't use RAR. Use 7-Zip (or .tar.gz, or just plain old zip) instead.

Golly can't open 17-490.rle – you are definitely using a non-standard program to write your RLEs. They look fragmented when I open them up in a text editor.

Lastly, regarding the manner in which you presented your syntheses, an RLE file by itself is quite hard to analyse for the steps. I created Shinjuku and its format to fill in that gap – and now it contains tens of thousands of directly machine-readable components. I would appreciate it if you just give component lines in the future.

Sometimes it happens. New ptterns turn out by means of combination of the list of still lifes with the list of converters. Process can take a long time and an exit quite big. Sometimes basic data contain comments. To correct quite easily: by means of the text editor remove superfluous.

Text editors only work for small numbers of files – and here's over 7000 of them.

I have a task for you. The attachment below contains 7773 RLEs, one for each 17-bit strict still life. Each RLE contains, as a comment in the first line, the cost in gliders of the still life within that RLE according to Shinjuku currently (unsynthesised still lifes have a cost marked as "infinity"). Your task is to process these files and reply back to me with only a smaller archive of RLEs, where each RLE there contains a strictly cheaper (better) synthesis of the still life within according to your archive. I will be expecting – I need to fill in gaps that were left by niemiec.py.

Perhaps you should welcome the help, no matter what the format. Writing conversions for formats isn't that hard, once you understand the data format. Yours is not some sort of special, canonical format that everyone is require to adhere to.

For example, it would have been nice for your list of 7773 files to also include the apgcode for the object, which would make object lookup a lot easier when loading into an SQLite database. On the other hand, a single file, with one record per object with something like this format would have sufficed--

Code: Select all

CREATE TABLE GliderCosts (
'apgcode' TEXT,
'gliderCost' TEXT
'rle' TEXT,
};

Perhaps you should welcome the help, no matter what the format. Writing conversions for formats isn't that hard, once you understand the data format. Yours is not some sort of special, canonical format that everyone is require to adhere to.

The problem is that Shemyakin's RLE files are riddled with errors, so there is no inherent format in them. Many of the files start with something from Niemiec's database, and two lines are added in the middle that make the RLE invalid; the given rules for many files are also incorrect (though the cells are correct). Shinjuku was designed from the start to have as few errors in its files as possible, and to be easily machine-readable/writeable – open knowledge in its purest form.

I don't understand much of SQL. Perhaps you could tell me what files you need to easily load the synths into an SQLite database?

You're using synthesise-constellation-ee9.py, right, not the synthesise-patt version? So the problem is not finding two beehives at specific offsets, it's finding one out of hundreds or thousands of those patterns where the reaction envelope doesn't get in the way of some pre-existing pattern.

That can definitely be done, but we might have to write some new functions in Python, or maybe switch over to lifelib or something. The three-glider collisions don't all produce the output constellation in the same orientation, so we'd have to run each one to stability, figure out which orientation it is, add whatever nearby obstacles we want to add to the initial state, and re-run the collision to see if everything still survives. It definitely seems worth having this as an option.

Also it seems like the current script is extremely fast, and so maybe it's time to make it work harder. We could process a sizable subset of four-glider syntheses and add all the interesting stuff to the search database -- all active reactions that drop to a bottleneck below N bits (for synthesise-patt.py) or that stabilize into three- or maybe four-object constellations (for synthesise-constellation.py), along with anything else we can think of to look for while we're doing the survey.

Hopefully there is some way to reduce this.

You're using synthesise-constellation-ee9.py, right, not the synthesise-patt version? So the problem is not finding two beehives at specific offsets, it's finding one out of hundreds or thousands of those patterns where the reaction envelope doesn't get in the way of some pre-existing pattern.

That can definitely be done, but we might have to write some new functions in Python, or maybe switch over to lifelib or something. The three-glider collisions don't all produce the output constellation in the same orientation, so we'd have to run each one to stability, figure out which orientation it is, add whatever nearby obstacles we want to add to the initial state, and re-run the collision to see if everything still survives. It definitely seems worth having this as an option.

Also it seems like the current script is extremely fast, and so maybe it's time to make it work harder. We could process a sizable subset of four-glider syntheses and add all the interesting stuff to the search database -- all active reactions that drop to a bottleneck below N bits (for synthesise-patt.py) or that stabilize into three- or maybe four-object constellations (for synthesise-constellation.py), along with anything else we can think of to look for while we're doing the survey.

You're a life saver, thank you so much. I was indeed using synthesise-patt and scrolling through thousands of traffic lights to find the beehive constellations I needed. Quite embarrassing that I missed this script, although it was hard to find synthesise-patt in the first place.

That's a fantastic idea that would definitely come in handy. You could use LifeHistory like this, but I'm not sure how much slower it would be:

Code: Select all

x = 7, y = 13, rule = LifeHistory
