B3/S238

Post by mike3 » January 1st, 2014, 5:00 am

Has anyone really explored this rule seriously? It is very close to Conway's Game of Life, but not quite it (as one might expect since the only deviation requires 8 live cells surrounding another live cell, of which there is only one way to have). Many familiar Conway objects work, such as the gliders and spaceships, even the simple glider guns. Lots of oscillators from Conway's work as well. Some don't, however, and disintegrate.

Other things I've noticed after playing around a little in Golly:

1. The frequencies of the various kinds of oscillator arising out of random garbage are altered. Pulsars are FAR more common in this than in Conway's -- there is actually a simple pattern:

Code: Select all

.*.
***
...
***
which produces a pulsar after 110 generations. I call it the "EZ-Pulsar".

2. Random garbage seems (maybe) to "burn" somewhat longer.

Has anyone else played with this?

Not sure about "seriously", but it's certainly been investigated by quite a few different people, off and on (no pun intended). It has a suggested name, PulsarLife, but that term hasn't seen much general use yet.

Isn't it "honeylife"?

Well, Dave appeared to be referencing this post:
Tropylium wrote:In case they do not, how about: "Pedestrian Life" for B38/S23 (since traffic lights do not occur in this rule), "Pulsar Life" for B3/S238 (given the frequent pulsars from pi heptominoes), and "Honey Life" for B38/S238 (since big beehives occur surprizingly frequently in this rule)?

Granted though, B38/S238 is also "pedestrian", and various other rules in the B3…/S23…8 range also produce big beehives more frequently than regular Life, but just throwing out some ideas.
So honeylife apparently refers to a different rule.

But no, none of those names have really caught on.

In fact, all pi-heptomino evolve to pulsar. I further reduce the predecessor to 5 cells only.
5-cell predecessor :

Code: Select all

x = 3, y = 4, rule = B3/S238

2-glider synthesis :

Code: Select all

x = 6, y = 7, rule = B3/S238

Actually, I was saying "honeylife" because a 6-cell row can also produce a honeycomb in 2 generations.
Also, I just tested that most ships in life work there, except the weekender, every corders and the seal (I haven't tested the lobster). So, this rule has c/2, 2c/5, c/3, c/4, c/5, c/6, c/7, c/4d, c/5d and maybe c/7d.

The name EightLife was suggested earlier, but that name has seen even less general use than PulsarLife.

I've experimented with adding an 8 to the B or S of certain rules, because the situation with 8 surrounding cells isn't very frequent.

In this rule the HWSS is no longer stable and evolves into a tub... *shrug*

This addition can have interesting effects, however. For instance, B35/S238 is a chaotic rule with sparky oscillators (unlike B35/S23, a stable rule with bland oscillators). Simply by doing some soup-searching I found a sparky p12 that can eat the 2c/5 ship that is common to these two rules.

Code: Select all

x = 7, y = 39, rule = B35/S238
3ob3o$o2bo2bo$bo3bo$2b3o32$2b3o$7o$7o$o5bo!
The B-heptomino, for some reason, lasts longer in B35/S238 than it does in GoL.

Interesting p22 forms in this soup from apgsearch:

Incidentally, apgsearch runs quite slow in this rule due to the abundance of pulsars.

An official name: EightLife.

Weak universality is proven via the usual rule-110 unit cell construction: I suggest testing already known life patterns via getallrules scripts bundled with golly.

Highlights:
  • EightLife soups produce about 55% more objects, on average.
  • Blinker is the most common object.
  • Tub and pond are nearly 4 times as common. They occur in the ash of the B-heptomino.
  • Hat is 4 1/2 times more common.
  • Mango is over 9 times more common. A glider colliding with a block can produce this object.
  • Cis-barge with tail is over 9 times more common. Still lifes with a cis-barge component tend to be more common because any pattern with a 3x3 block with one corner touching a pre-block in cis orientation will immediately evolve into a cis-barge object.

  • Ship is the only object among the 25 most common to be less common than in Life, by about 71%.
  • Pentadecathlon is 27% less common. The 10-cell line predecessor does not work in EightLife.
  • Integral is 59% less common.
  • Dead spark coil is 74% less common.
  • Ortho-loaf on table is 8 times less common.
  • Aside from two infinite growth patterns, heavywight spaceship is the only top 100 object in Life that does not work in EightLife. No objects unique to EightLife showed up in the top 100.

Annoyingly it seems to be unextendable in any location-independent 2-state range-1 Moore rule.
Each day is a hidden opportunity, a frozen waterfall that's waiting to be realised, and one that I'll probably be ignoring

Edit: How I found this spaceship:
Initially, my goal was to find an Anura-like spaceship in B38/S238 (aka HoneyLife), because none of the known 3c/7 spaceships in Life worked in HoneyLife.
I made a w15 gutter-symmetric search for Anura's seedcolumn without any spaceship.
After 2 or 3 weeks, I tried to switch w15 gutter to w16 odd symmetry after reaching Anura's frontend.
Memory usage gradually increased to 30 GB and then dropped to 20 GB.
When memory consumption started to increase again, I reduced the width to speed up the search.
After ~2 days of searching, I found a 1-cell near-miss (2 thirds of this spaceship, before B-heptominoes). I tried ikpx2 to complete it, but found no low-hanging fruits. Then I reduced the width of LSSS search space again, and found another near-miss (with B-heptominoes). This time ikpx2 really found a completion shown above.
Unfortunately, the same search with ikpx2 failed for CGoL.
The above instruction shows that my search was not exhaustive for width 31, so smaller ships are potentially possible.
The latest version of hex-gliders.db have 668 gliders from OT hexagonal rules. Let's find more!
My CA (13 rules)
My scripts: new-glider.py v0.2 (new version), nbsearch2a.py, collector.py v0.3
