👀 Some source code analysis tools can help to find opportunities for improving software components.
💭 I propose to increase the usage of augmented assignment statements accordingly.

Hi!

First of all, thank you for making this. It's truly amazing. I'm trying to make the Python code run on my computer, but after installing the requirements I'm getting this strange error. Any idea what's going on here?

Hello there. I design a logo in my free time. I want to design a logo for you. What do you think ? I want to contribute you.

Hello, I am a big fan of your work! Quick question, are there some extra steps I need to take to enable GPU support, at least on Windows? (I would be normally using linux but my dual boot setup is currently broken)

I had to tweak the dependencies to get it to work right, but I'm still using mostly the same install. I also had to install PyCUDA to get Reikna to do anything, I think this is normal but I couldn't find anything about it specifically for Lenia. However, I still get an error saying the compiler preprocessing of the CUDA shaders failed.

I have the latest stable NVIDIA graphics drivers, and an NVIDIA GTX 1650. I tried doing a clean install of the graphics drivers, and all of the CUDA test programs seem to work. Is it possible my GPU or operating system is not fully supported by Lenia Python? Or am I just overlooking something? My adapted requirements.txt file is attached below if it helps. Let me know if you need any more information.

Hi!

First, I'm astonished of lifeforms' beauty.

It seems like there is no Webpack / Babel / other build solution involved. When I cloned the repo, I just opened JavaScript/Lenia.html and it worked.

Please, consider using GitHub pages to host Lenia, so everyone visiting this page could just click a link and check out Lenia for themselves, without cloning the repository.

Some creatures are not working. Fix or reimport from web version

text - undeclared variable

That's it. If I had more energy, I'd fix it.

I got all the dependencies installed (gentoo Linux using portage had everything apart from renia, so a local renia checkout with $PYTHONPATH specified) and then when I tried to run LeniaND.py (I was keen for the python version), I got a traceback from reikna:

File "/home/dan/dev/python/lenia/Lenia.git/Python/reikna/reikna/cluda/ocl.py", line 114, in _copy_array
dest.set(src, queue=self.queue, async=self.async)
TypeError: set() got an unexpected keyword argument 'async'

I guess this should probably be reported to the reikna github (if there is one!) but I thought I might as well let you know - and yes, maybe this would have worked if I had a newer nvidia-drivers installed? (currently on 390.87) but the code could also check if that arg is allowed before passing it perhaps?.

I was able to run LeniaND.py fine after removing that single 'async' argument from the call to 'set()' mentioned above.

Refer to JS version - PrimordiaReal-Animals.js

The javascript and python versions use different formatting for copying/pasting fields. Please make a standard that supports all platforms.

Hello my name is Michael Simkin, I'm game of life enthusiast and (among other discoveries) I've constructed adjustable speed spaceship that solved every speed below c/4 in CGOL.

I really liked your rules collection and the aesthetics of continuous rules. But I see people just invent new rules and don't invest time to investigate the simplest properties of the rules (and maybe meaningful modification in order to support university). For example what are the possible results of two gliders collisions? Is there also oscillators and other gliders in the same rule? How about glider reflector and duplicator? Can we make construction arm and make Gemini in some of your rules? In order to have Gemini we need to implement HashLife algorithm, as Gemini basically means universal construction, and the iterator implementation must be sparse.

CAs are very useful for self replication, and continuous self replication never been explored at all. Maybe there are some interesting shortcuts available in this collection of rules. Maybe we can make a spaceship that can turn in 5% for example. Some interesting properties and search utilities from CGOL can be used to find spaceships in those rules as well.

EDIT I noticed many of the rules contain interesting creatures but random soup is exploding. Do you have a "real" CGOL like rule where:

1. Spaceships are many times spontaneously appearing.
2. Random soup is usually (with probability higher than 99%) ends with only oscillators + spaceships.
3. Infinite explosions are extremely rare (less than 0.1%).
4. Complete death from random big enough soup is rare (less than 5%).
5. A large set of different spontaneous creatures are available in the same rule (like in CGOL we have *WSSs except of gliders). And oscillators/still lifes have many different shapes.

I am using the python version, and could change the code if needed.

if you could point me to documentation that would also be great
