Game of Life Links

Post by Nathaniel » March 5th, 2009, 3:25 pm

Rather than having an increasingly out-of-date list of links that only I (and a few moderators) can update here, the list of Life links is now maintained on this LifeWiki page.

Various useful pieces of Life software are still attached below.

I know of some websites which aren't on the list:

http://www.geocities.com/conwaylife/ - Pattern Statistics and software.

http://www.ibiblio.org/lifepatterns/lifepw.zip - Another pattern collection by Alan Hensel, this one includes patterns from other rules.

Added this link in the "Stable Life?" topic last night, then realized it wasn't in your List o' Links...

http://nickgotts-eventful.blogspot.com/

["GoL Patterns with Eventful Histories", about Life patterns that stay "interesting" (meaning unpredictable) for a long time.]

MIght also be worth keeping an eye on Golly's reference links page, at

http://golly.cvs.sourceforge.net/viewvc ... /refs.html

-- there are a few resources there that aren't in your list, such as Calcyman's Life pages:

http://myweb.tiscali.co.uk/calcy/life/

(good summaries of stable technology, Corderships, and current unsolved problems).

Dean Hickerson's Life pages now have a new home at

http://radicaleye.com/DRH/

And there's an updated Hersrch with a few recently-discovered conduits and other miscellaneous fixes, at

http://cranemtn.com/life/files/Hersrch-15June2007.zip

I have some more updates to do on Hersrch, but anyway it needs a better home than buried in my pile of linkable Life junk...

I couldn't see http://www.yucs.org/~gnivasch/life/index.html in the list. Gabriel Nivasch's page is great, especially the still life generator, it helps no end with stabilizing "almost patterns".

Excellent! I see Dean has a p30 glider stream bridge. I tried to build one a couple of months ago, using XOR reactions. My first attempts failed, due to off-by-one timing errors, but I eventually achieved success. However, the resultant circuit was too large to be practical. I tried a different approach a few weeks ago that is much simpler, and possibly even more compact than DRH's method. If it is, I'll post it in the Patterns forum.

My new approach is quite simple. Each p30 stream is converted to a pair of p60 streams. The four streams just have enough room to cross safely. The p60 streams are then recombined into p30 streams.

Ugh... There's so many good search programs that use terminals/consoles and I don't know how to run them... I am a Java programmer. I wish someone could make a GUI version of these in Java, so everyone can use them, not just the computer savvy and people with the ability to compile C and C++.

I've uploaded a list of links to LifeWiki to avoid the middle man that is this thread:

http://www.conwaylife.com/wiki/index.ph ... Life_links

As such, I propose keeping that list as the list of "good links" (whatever that means), and this thread can be used for posting any links (your own site, single blog posts, whatever floats your boat).

Are there any descriptions anywhere of the quicklife algorithm? What optimisations does it use?

The Golly credits state that the quicklife algorithm uses some ideas from Alan Hensel. Maybe Andrew will post on this topic, but in the meantime, here's a link to a quick description of the algorithm Alan uses in his applet, plus links to the Java source code.

Tom Rokicki wrote the QuickLife algorithm (and HashLife, and all the other algorithms included in Golly, except for RuleTable which was written by Tim Hutton). I'm hopeless at bit-twiddling and Tom is hopeless at GUI stuff, so we make an excellent team. :)

You might want to read Tom's comments in qlifealgo.h which can be found at Golly's CVS page:
http://golly.cvs.sourceforge.net/viewvc ... golly/src/
Or download Golly's source distribution.

http://mysite.verizon.net/live_free/glossary.htm - Has patterns from different rules (B2/S0)

I'd found similar pages to this dedicated to other life-like rules but lost them. There was one about 34-Life where the owner had managed to run a census on the rule (using a toroidal universe I think). Does anyone know and have a link to that site?

Edit: I found the site. It's http://web.mac.com/teisenmann/34life/main.html

How do you use the programs which are .c files (eg. ofind.c)?

You have to compile them yourself.

You compile them with a dedicated C/C++ compiler, like Microsoft Visual C++ 2008 Express Edition (downloadable for free).

A nice link that I'm not sure should be in the LifeWiki page, as it deals with a variation that is not strictly a cellular automaton. (You'll see what I mean.)

Interesting, but the algorithm is not revealed:

It looks like some kind of reaction-diffusion system. I've played with these myself - they can often give you some very beautiful emergent patterns.

It's a shame he doesn't talk about the details though.
