What does this output text in my apgluxe mean?

It is rare, at least in my experience, but otherwise normal. It simply means that the program does automatic garbage collection.

It is rare, at least in my experience, but otherwise normal. It simply means that the program does automatic garbage collection.

So why does apgluxe sometimes do automatic garbage collection?

EDIT: A problem haul is k_32GfCA8fqv8j. Run it for about 300K soups.

[confocaloid]

It may or may not be some kind of a problem with the choice of the CA to search ("pathological soups", unusual growth, and so on) However, it is unlikely to be a problem with software. https://gitlab.com/apgoucher/lifelib/-/ ... heads#L166

When I try to compile apgsearch for b01c3s23, it gives me an error:

(not an answer, but possibly helpful or interesting)

There were earlier cases where people had some kind of issues with B0 involving CAViewer, for example viewtopic.php?p=176537#p176537 (although the error was apparently different in that case).

Interestingly, an old haul (2023) was not yet processed: https://catagolue.hatsya.com/haul/b02-m3-os0h/C1 I remember there were several other cases like this one.

So far there was little investigation of B0 that is visible on Catagolue:
https://catagolue.hatsya.com/rules/isotropic_other
https://catagolue.hatsya.com/rules/isotropic_other-hex
https://catagolue.hatsya.com/rules/isogeny_other
https://catagolue.hatsya.com/rules/isogeny_other-hex

At least, there is always the possibility of creating a .rule file with a ruletable implementing three-state CA (cellstates 0/1 in even generations, cellstates 0/2 in odd generations) to emulate two-state B0 explicitly. Tools like apgsearch/lifelib should support the usual Golly-compatible .rule files without needing CAViewer download.

The Catagolue object page seems to be missing its LifeViewer.

The Catagolue object page seems to be missing its LifeViewer.

Confirmed; not only that, but the glider synthesis/glider gun viewer is missing too.

This may be some kind of one-time error during an update, at least I don't see any recent commits that look like they could be related:
https://gitlab.com/hatsya/open-source/c ... type=HEADS
https://github.com/rowett/lifeviewer/commits/master/
and there were viewers when I looked a few hours ago, and it might fix itself later.
(edit: apparently it did fix itself a few hours later.)

but how i install it?

Hi. I'm trying to get started with Python, and I thought it was going to be as easy as lua. But lua comes as a pre-packaged binary with the golly installation.

My system:
NAME="Ubuntu"
VERSION="20.04.6 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.6 LTS"
VERSION_ID="20.04"

Python works perfectly on the terminal:
Python 3.8.10 (default, Mar 18 2025, 20:04:55)
[GCC 9.4.0] on linux

But when I try to run any of the included python scripts, I get this:


Any hint ?

Hi. I'm trying to get started with Python...

My system:
NAME="Ubuntu"
...

Python works perfectly on the terminal:
Python 3.8.10 (default, Mar 18 2025, 20:04:55)

In the dialog box try adding ".so" to the name and clicking OK. That is, your dialog box should say

Code: Select all

libpython3.8.10.so

If that doesn't work, figure out the correct name of the libpython3 shared object (.so) file by running the following command in the terminal:

Code: Select all

ldconfig -p | grep libpython

If just the name of the shared object isn't enough, you will need to put the full path to the file in the dialog box.

It was "libpython3.8.so.1.0". I should have figured it out myself. Thx!

Maybe rename it to libpython3.8.so or whatever.

How are people using apgsearch with B0 rules? Whenever I run them I always get an error.

A lot of hauls seem to be from apgsearch version 5, as recently as 2021-2022.

Maybe your devices are too old or slow. (Although LV is fine on the iPhone 7 I’m writing this on.

It might also be because your devices are on low power mode or low battery or energy saving mode or something.
