I think precomputing the rules using a PRNG wouldn't be a particularly serious problem. It would just mean that a pattern would evolve differently each time (unless the same fixed seed is used always). Might be unexpected, but also might be useful if the PRNG does minor tweaks that don't affect mos...

I currently see around 70-80 guests on the forums.

Now up to 93 guests (10:00 PM UTC-5). Yet I got no error, ever.

Must be a momentary glitch?

Bump "Re: Rule Tables + Weighted Life + Larger than Life" This other topic seems mildly related, so I’m linking to it. My other idea is that since Golly has Lua and Python built in, the simplest solution to all the rule table problems may be just allowing the user to literally write an actual trans...

I'm not sure it's a good idea to allow negation inside a rule. ... Neither of these possibilities feels like "the single best choice" to me. I was thinking more along the lines of typical set negation you learn in high school algebra 2 class -- i.e. "not A" means the same as U-A where U is all allo...

Another hybrid CA I worked on elsewhere and I think it would be worthwhile to post here. It's called Tetrazine , and it's a hybrid of Wireworld++ , DECA , and NoTimeAtAll . I just dug up an old pattern I made in Tetrazine -- a big hexadecimal counter. The git repository I have it checked into says ...

One will need to choose the syntax. Prefixing a tilde makes it easy to misread "~a" as negation of the value of "a". Maybe prefix with asterisk instead? Or that would be confusing too, for some other reason? After some more thought, I think the best sigil would be &, sort of like int& in C++ where ...

Looking at this, I have an idea to sort of implement tommyawesome's proposal. Normal var declarations behave as expected. So if a has n values, "3, a, a, 0, 0, 0, 0, 0, 0, a" expands into n rows. However if you put a tilde before the variable name it unbinds the variable within that transition (maki...

Code: Select all

x = 8, y = 8, rule = R2,C2,S2-3,B3,NF

weird oscillator i found

That looks like a beacon and two blinkers overlapped.

Somehow stumbled upon dani's userpage with the archived source for the catglue bot and then tried to take the link for testitemqlstudop's gitlab fork, but the link is broken - and it looks like it's a formatting goof or even a bug in mediawiki that's to blame. The href on the rendered page is https:...

it says catagolue instead of catalogue. glad to be the first one to point out this typo.

AFAICT it's an intentional misspelling - it's switched so it has the letters "GOL" in it -- for "Game of Life".

(actually about ruleloader, but I couldn't find a dedicated thread about it. if there is one, please move this to it.) It would be nice to have a symmetry (in the symmety:____ line of a ruletable) that's like permute, but preserves wether something is orthogonal or diagonal. (or, if there is a symm...

Thanks wirehead! To be honest, I'm pretty stubborn when it comes to using libraries - I only include them in my own projects when I really need to (on top of which I believe that solution requires jQuery which I don't include). Fortunately there aren't that many touch interactions to code for and I...

for the time being I haven't coded proper support for mobile platforms.

I'm no help with the C code (yay for hashlife!), but touch support might be as simple as remapping touch events to mouse events.

p.s. is the SoL source code public/on github/sourceforge etc?

LifeViewer is now open source.

THANK YOU for releasing your amazing work to the community!!

Now that LifeViewer is on Github, if I find bugs in LifeViewer would the Github bug tracker be a more appropriate place to put them, or would you still prefer using the forums?

Hi James -- welcome to these here forums! One piece of feedback -- the gesture to place cells with the brush (right click) is a bit counter-intuitive -- and a bit of an odd choice at that considering that left click doesn't do anything. The other major programs (Golly, LifeViewer) use left click to ...

Does this qualify as a replicator? And if not, what kind of infinite growth is this? x = 4, y = 4, rule = B2en3eijy4-ekny5kq6-c7/S1c2ik3-ny4-aitw5a6-en78 b2o$o2bo$o2bo$b2o! I don't think that's a replicator, more just a chaotic messy plus sign. Replicators have to, well, replicate, and I am not see...

In my experience, it's something like 20 minutes of inactivity you get logged out. Maybe there is something in your browser that is keeping you logged in that broke recently? I was never able to stay logged in continuously without being actively active.

Well, I played around with it and found a whole bunch of still lives. No spaceships.

I actually think spaceships are impossible in this tiling because it is inherently anisotropic, so it may not be of much use. Feel free to prove me wrong. Neat demo though!

Request for two-finger touch zoom on mobile.

It is getting very annoying to use the zoom slider and have the pattern of interest get moved offscreen because I didn’t center it properly.

Nice work! Unfortunately, it seems to me that no finite NxN box has weights that would give a strict 1/2 density bound. What if there was an algorithm which could, for any real number larger than 1/2, produce a set of weights in a finite box which gives a density bound less than that real number? O...

Isn't it intuitively obvious from symmetry?

That appears to be a fair proof.

there are threads on these forums where astonishing global real time collaboration is taking place... These forum are about as real-time as Git is for code collaboration. I'm looking for something where you literally get to see what other people are doing with the pattern at the instant they are do...

Have you seen the LifeCompetes website? Currently in working order here , I think, though you might need to recruit a few more people to try it out with you simultaneously. It can be either a competitive game or a highly collaborative one, depending on who shows up! People have managed to work toge...

So we all know that Google Docs is really neat. If two people are in the same document at the same time, you can see each others' cursors and selections as you edit the document (nearly) simultaneously. Now I was wondering what, or how, this kind of real-time collaboration on cellular automata patte...

Probably would be an easy conjecture to prove: No isotropic rule has a 1-cell spaceship. And no isotropic 2-state rule has a 2-cell spaceship.
