Out of curiosity, does there exist a GPU accelerated version of catforce, I’m assuming not because there is currently not mention of such a script. Is someone willing to make one if necessary?

is there a python script of hacked apgsearch 1.x i can use in replit?

Posted: **August 10th, 2024, 7:21 am**

I want to know, which guns in collection (in directory full of rle files) contain specific object (Rich's p16 for example).
Is there a program that allows to do such search?
If not, I plan to make one.

upd: Done.

There's some Python code in this "recognizer" folder that could be adapted to do that task fairly well -- but not particularly quickly.

A much more efficient option would be lifelib's pattern-matching functionality. Documentation for some lifelib functions is still somewhat sparse and potentially puzzling, but there are code snippets like this one available that show how it works.

The last line says that you don't have 'git' installed. Do you have git installed? If not, how did you download ikpx2?

If you downloaded ikpx2 by any other method than cloning the ikpx2 repository, then I'd recommend deleting everything and starting over and doing that. There isn't a specific LifeWiki tutorial on using Git to clone ikpx2, but it's the same process for any Git repo. See the notes in Tutorials/LLS but substitute the ikpx2 repository for the LLS one.

The ikpx2 quick start guide is maybe a little _too_ quick, since it doesn't mention starting by cloning the repo.

You'll need to have git and (based on a quick review of this thread) g++ installed, and then I think the submodule install will grab the rest of what you need. I haven't tried this recently, so maybe someone else can correct me. Really maybe the thing that will solve the most problems is

sudo apt-get install build-essential

... but you'll need to be able to follow the first few steps in the LSS tutorial before you'll have a Cygwin or WSL2 or other Linux-ish window open where that command will work.

It would be nice to press hotkey in Golly and after automatic gun verification, normalization and comparison with Catagolue, have option to upload result with one click.

However, I'm not sure if Python and Lua plugins in Golly have restrictions preventing contacting Catagolue.

I already had cygwin installed but i am missing many directories, such as sudo and git (look i did not think i needed them since I only wanted to use gfind and its variations). does running the "setup-x64_64" folder replace the cygwin I already installed or does it add on to the cygwin I already installed?

It adds on. At least in my experience, when you run the installer you'll see things checked off if they're already installed, and the option to change what's checked and unchecked so the installer can do the relevant new installs/uninstalls.

Tawal wrote: October 14th, 2024, 7:08 amBut I had at least 2 errors :

The first of two errors is probably because you need IPython to be able to show viewers in an interactive session.
("probably" because I don't have IPython and didn't test these features myself.)
I just tried to run "x.viewer() myself, and in my case it fails (as expected), with the following error:

Code: Select all

ModuleNotFoundError: No module named 'IPython'

Second error seems more interesting. The line "Instruction non permise" at the end of your output suggests that maybe you have an old system which does not support an instruction, while lifelib expects that instruction to be available.

I was able to run the following:

Code: Select all

Thanks for answering.
I encounter the same error (SSE3) when I tried to compile slmake/slparse.
I have to change my material …

I have a different question :
In Golly, is it possible to launch a Python 3 script with options and arguments (that the script can handle these) ?

If the script is running within Golly, then the usual "command-line arguments" are unlikely to be useful.

However, you can use instead the scripting commands listed in the Golly help, to get access to the environment (e.g. read/modify the pattern in the current layer, get/set the current layer name, etc.)
https://golly.sourceforge.io/Help/python.html#commands

In particular, functions g.getstring and g.query can be used to get some kind of interactive input from the user.
The functions g.note and g.warn can be used to let the user interrupt the script in the middle.

Alternatively, getclipstr/setclipstr can be used to pass data between the running script and the system clipboard. However, that can be problematic in practice, because the user may need/want to use the system clipboard for another purpose at the same time. If possible, it is better to avoid writing to the clipboard, and even better to avoid using the clipboard at all.

One more time thanks a lot for fast answering

Another question :
Does Golly use lifelib ?
If yes, why does it works in Golly and why I'm not able to make it work in a Python shell ?
(Instruction set detected SSE3 ==> Instruction non permise)

Tawal wrote: October 15th, 2024, 6:03 am Does Golly use lifelib ?

No. AFAIK (at least currently) the lifelib library and the Golly application are two mostly-independent projects. (There is some compatibility in terms of supported features / notations / data formats, but neither of two projects is part of the other.)

IIRC there were some discussions about whether or not it would make sense to integrate lifelib and Golly together.
I think that may be impractical, and maybe unnecessary. Golly is good for "interactive things" when the user works with some patterns. lifelib is good for automated/semiautomated tasks.
(I can imagine there could be yet another library, for use cases that are not covered by lifelib. For example better handling of toruses and other topologies different from the usual infinite plane, ability to work with many different CA in a single script without having to recompile, etc.)

rokicki wrote: April 19th, 2022, 11:50 am [...]
Implementing lifelib operations requires a hash cache of operation results which
gets into golly's memory limit code, not to mention there are at least two distinct
hashlife implementations in golly that would need separate implementations).

I don't think Golly needs to be everything; I think having additional tools like
lifelib and lifeviewer that have a different "take" on things and excel in different
ways is healthy. But if just smashing together macrocell tiles (as the above code
would do) is useful, that's pretty easy to implement.

dvgrn wrote: April 19th, 2022, 12:09 pm Yup, no point in trying to duplicate lifelib, but there are occasional macrocell-related things that I'd like to be able to do in a Golly script, and mccopy() would take care of a fairly good fraction of them.
It's also worth noting that they're not two mutually exclusive worlds where you need to decide between one or the other: a Golly script is just a Python script, and it can import lifelib just like any other script. You can move a universe from Golly to lifelib, and vice-versa, by using temporary macrocell files.

It shows that the reaction is split into two stages, which is what I'm trying to avoid. So in the script, I changed line 408

Code: Select all

x = gnf[-160:, :]

to

Code: Select all

x = gnf

I thought this was going to remove separation of stages and build an actual seed, but it resulted in an error. This was the output:

I don't immediately know the answer to the gnf2seed question -- maybe someone else can help with that.

However, if your ultimate goal is a one-glider seed for that HWSS backrake, it seems like gnf2seed might produce an unnecessarily large messy solution anyway.

You're very close to having three copies of the same sub-rake activation there. How about completing the 1-glider seed for one of the p80 glider forerakes, then use that same seed twice, and then modify it slightly to produce the p80 glider backrake? Then you'll have reduced the problem to building a one-glider seed for the three activation gliders.

How familiar are you with the splitter and turner collections, and how to use the current arcane rating system to find one that works for a given purpose? E.g., there's a walkthrough here, the collection of rated turners can be found here, and splitter categories are here -- don't know if any of that will be useful.

Is the spacing of the component parts important, or would a seed for a more compact version of the backrake be preferable, like

Is there a script that can convert LifeViewer Pattern to Animated GIF or vice versa?

Do we have a way to display pattern distributions for different symmetries? I am curious about what "index fossils" exist across various symmetries. These are the two that come to mind right now: the top one produces an xs96 that is about 50 times as common in 1x256X2+1 as in D4_+1, and the bottom one produces an xs18 that is about a million times as common in i2x128 as in C1. There are likely more that no one has noticed yet.

Code: Select all

x = 45, y = 20, rule = B3/S23

Do you mean something like this?

Code: Select all

Instead of requesting an entire census, you can request just one tabulation:

I want to start searching, probably starting with oscillators.

What program(s) should I start with downloading to begin searching, or at least where could I find the steps?

If you're using Windows, WinLifeSearch would be a great option. It's easy to download and use, and in fact the first search program I ever used.

There's also CatForce and its relatives, if you want high periods. There's still stuff to find; there are several periods where we don't have any good sparkers, such as 17, and sparkers of certain types of periods 13 (for 39 and possibly 26), 14, 18, and 35 would find guns of missing periods.
