I am using 64-bit Golly 2.7 with Debian 8 about a year. It works fine. I used 64-bit Golly 2.5 too.

Golly is a bit slow here. Xlife is a bit faster. However the next example shows much faster speed.

It gives 250 generations per second for 4096x4096 torus topology for Brian's Brain! Golly gives 1-3 gps, Xlife 9-12. So the GL programming may ...

This is a student work. Any feedback is welcome.

Xlife supports the hashlife algorithm - http://youtu.be/IunDIzS012c
It is the prereleased version - it is only available from the SVN-repository.
All links - http://freecode.com/projects/xlife

Subset of Xlife is also ported to the 8-bit world of retrocomputers. :)
The speed of these computers is ...

Xlife 6.7 is just released -- http://freecode.com/projects/xlife.

I've just updated Xlife page at LifeWiki. Please help to check and improve it. I've also created the page for Eric S. Raymond.

Thank you very much for the link. I've just added a comment to UnboundVariables topic. BTW I have question about ruletree rules format. Is it precompiled, unreadable form of table-format? It looks so. Why does Golly ask to select between ruletree and table formats? IMHO it would be convinient to ...

I've tested make-ruletable.cpp---it is a very useful program. However I'm curious. Where rules in the format like
1,[0,2],0 -> 3
are used? It maybe useful to support them by Golly. IMHO the support of "the unbound sign" (e.g., *) for the variables may be a bit better.
BTW ESR may continue the ...

I have an idea how to optimize the table-format. IMHO The best way is to use a special symbol (like $) to force equality of states in a rule. So the next text
var a={1,2}
var b={1,2}
1,a,b,2,a,4

maybe replaced by
var a={1,2}
1,$a,a,2,$a,4

To preserve existing table-files we had to use the special ...

Thank you very much for the answer. :-)
I agree with your arguments. However there is other side.

1[12][12][12][12]2



var a={1,2}
var b={1,2}
var c={1,2}
var d={1,2}
1,a,b,c,d,2


Xlife v5.0.8 was with Debian until version 6 where it was replaced by Golly. I plan to reinclude updated xlife ...

I used CODE section for this but it looks a bit wrong. Is there something like table-tag of html?

Google wiki page ( http://code.google.com/p/ruletablerepository/wiki/TheFormat ) about n-state rules in xlife r-formats has a cite "The problem is that it doesn't provide enough compression." It asserts that table-format has better compression. I've just performed appropriate measurements. I use ...

Version 6.5 is released. It supports up to 256 states now. So it is possible to use such a beauty as the snowflakes world by /1/256 rules--it is very impressive with bounded grid--try
/1/256:T1000x800 with one alive cell. Golly is a bit slow for this task. ;-) BTW surprizingly Xlife shows the ...

Thank you very much! IMHO this timing script should be published.

I've just performed several experiments. It is surprize that Jon Bennet 1989 code only slightly modified shows the best speed for the exploding and chaotic patterns. All tests use only two adjacent cells (brick) at state 1. XLife shows the speed of the evolution about 100% and 50% faster than Golly ...

Thank you! :-) I'm a bit obsessed by Xlife so several interesting features of Golly missed me. I'm curious. May Golly use pseudocolor modes? I've made a demo page (http://litwr2.atspace.eu/demo/demo.html or http://94.143.43.217/LW/demo/demo.html) for Xlife. May Golly cover all listed features ...

Version 6.4 of XLife is released. It is still with Spartan style Xlib interface and doesn't support hashlife. However it begins to support torus and plain topology, the history for any 2-state automata, pseudocolor modes, ...

The history mode maybe toggled by @ keypress. Will Golly team add this ...

Version 6.2 of XLife is released... It is slightly accelerated so it can handle the big patterns now, e.g., `golly-constructor' (Codd rules), Universal Turing Machine, or even `caterpillar'. Lifesrc is removed. Added support for the format signature line (##XLife) in the output files.

Xlife is ...

I've added some new features so XLife 6.1 is released.

I consider my work as digital restoration. It keeps spirit of original code, fixes a lot of bugs, added several improvements (commands, new types of automata, formats, etc).

The novice users may find this program a bit unfriendly but little ...

Version 6.0 of old XLife is released... It is based on 5.0.8 Debian Linux version and lesser on 5.3 OpenBSD version. It doesn't support all features of v5.3 (see MISSED). However it runs at modern systems (several Linux 32/64-bits distributions were tested) and provides a lot of features (see ...
