Non-explosive B2a rules

Postby danny » June 2nd, 2019, 9:42 pm

This is a thread for non-explosive B2a rules. One I find interesting is B2-ek4i8/S04et.

The couple known elementary oscillators:
x = 28, y = 25, rule = B2-ek4i8/S04et
9bo2bo$20bo5bo$9bo2bo$22bobo$22bobo5$20bo5bo2$o2bo5bo2bo9bobo$6bo15bob
o$o2bo5bo2bo2$6bo14bobobo$21bobobo2$19bo7bo3$20bo5bo2$22bobo$22bobo!


The right family is infinite, the only still life is the dot.

There are two common spaceships, a 6c/6 and a 4c/4:
x = 9, y = 10, rule = B2-ek4i8/S04et
obo$6bobo$6bobo$obo5$obo$2bo!

The latter is way less common.

There's almost a c/2 spaceship that can be turned into a wick:
x = 16, y = 3, rule = B2-ek4i8/S04et
bo3bo2bo3bo2bo$2o5b2o5b2o$bo3bo2bo3bo2bo!


The domino evolves into 4 dots and 2 6c/6 spaceships:
x = 1, y = 2, rule = B2-ek4i8/S04et
o$o!


Two dots can reflect a 6c/6 like so:
x = 24, y = 4, rule = B2-ek4i8/S04et
obo20bo$6bobo$6bobo$obo20bo!

They create p30+12n oscillators.

There is a replicator, shown here with an endpost:
x = 28, y = 16, rule = B2-ek4i8/S04et
o$o$o$o$18bo$12bo5bo5bo$12bo5bo5bo3$15bo5bo5bo$15bo5bo5bo$21bo$3bo$3bo
$3bo$3bo!


Moving objects:
x = 82, y = 49, rule = B2-ek4i8/S04et
6bo$o5bobo$o5bo$6bo4$6bo$4bo2bo$obobo$o2bo2$2b2obo2$o2bo$obobo$4bo2bo$
6bo3$11bo$6bo3b2o6bo$o5bo4bo$o5bo12bo6bo$6bo10bobobo$17bobobo3bo$7bo

I love this rule! Here's a p6 siderake for the 4c/4 and a variant of the 6c/6:
x = 15, y = 9, rule = B2-ek4i8/S04et
2o2b2o6b2o2$3b3o4$11b4o2$12bo!

This is the first B2a rule I've ever seen with a natural p3, let alone such a small and common one in such a non-explosive rule.

EDIT: Unfortunately, it doesn't seem to be apgsearchable. I don't like how apgsearch handles B2a rules in general — square soups tend to generate too many multi-engine puffers and rakes on the edges. I may try my hand at a bit of hacking to create a pseudo-symmetry with some sort of alternative soup shape that's more B2a-friendly, but I don't have time at the moment (maybe tomorrow).

Your rule doesn't quite cut it because there is a natural breeder.
x = 18, y = 13, rule = B2-ek4i8/S04et
2bo5bo$11bo5bo$11bo5bo$bo7bo$2b3o2$6b2o3bo$11bo5bo$11bo5bo$7bo3bo$2o4b
o2$2o!

EDIT: You might be close to one that does work, though.
x = 4, y = 3, rule = B3-q4z5y/S234k5j
2b2o$b2o$2o!

b2ac3qs0
b2ac3qs01c
b2ac3qs03ac (most apgsearched)

b2aci3q4qz5i6ns01c4a5k
b2ae3acr4eis2e3c4cw5k

similar family, has a 2c/18 rake

EDIT: and no replicators, unlike most B2a rules

Just place an alive ring of cells around it e.g.:

I know it's a natural breeder, but this is interesting oblique behaviour in a non-chaotically-explosive rule:

Re: Non-explosive B2a rules

What is the pseudosymmetry called?

I'd like to try this rule in it.
x = 76, y = 22, rule = B2ac3akn4ikt5qr/S03i
2b2o12bobo$15b2ob2o$b4o$37bobo$o2b3o30b2ob2o$bo13bo3bo15bo5bo32b2o$2b
2o33bobo34b2o14$18bo$18bo!

Interestingly, the second c/2 does not use the B2a transition. At the moment, it is the only known ship with this property.
x = 4, y = 3, rule = B3-q4z5y/S234k5j

I'm pretty sure someone else found a B2a-less spaceship before that.

I found some B3i and B1e agnostic ships, but the only ship I've seen on the forums that is B2a agnostic is that one. They posted that ship somewhere else a while ago, maybe you are remembering that. I may search for some more.
I and wildmyron manage the 5S project, which collects all known spaceship speeds in Isotropic Non-totalistic rules.

Things to work on:
- Find a (7,1)c/8 ship in a Non-totalistic rule
- Finish a rule with ships with period >= f_e_0(n) (in progress)

I went through the same mental process. Here's the original post.

One of the B2a rules with a pseudosymmetry census is B2an3ekr4i7c/S1c2ci3iqy4-a5678. The pseudo-symmetry is called ee9-test. I don't know if the modified hashsoup has been published, but the soups appear to all look like this:

Confirmed. However, I don't understand the existence of some linear growth pattern. Anyway - this is quite fast - almost 1000 soups a second. Unfortunately we don't get ships from this, just oscillators (and indirectly guns).

By the way - I think one of the most interesting B2a rules I know of.

In general - I think it is worth adding an 'eating' frame around the soup - B2an3ekr4i7c/S1c2ci3iqy4-a5678 is an excellent example - otherwise it would have been tough to find guns fr the periods p=7 to p=32.

This rule contains a ship that travels at 10c/14o. It was discovered by wildmyron (possibly using LLS) in January 2018. I rediscovered the same ship independently later on, but I can't remember when. Might this rule be apgsearchable with the border?

From what a can remember I found that ship with some variation of searchRule-matchPatt.py

I would say that adding a border could definitely help with apgsearch-ability of this rule, but I don't think you could rule out that breeder appearing even with the border.

By the way, does anyone know of an oblique ship anywhere in this rulespace?

Which rulespace precisely are you asking about?

Here's one that is apgsearchable and has a (2,1)c/3:
