The state 8 cell makes them die. If we remove state 8 then the entire thing is solved.
However, this cause

This is how Evoloop behaves without state 8:

See the stateinvestigator rule for how to add those. State 2 is confusing and I do not want to edit your rule.

This rule has probably been explored before but I like how this oscillator is a polyomino in two consecutive steps and a polyplet in the two next ones

I looked, but I don't see anything else that it can complete.

You mean infinitely many 'completely-inaccessible-from-outside-like-cribbage' p19 oscillators.
We need to find a sparky p19!

I found that most construction arms in most CAs use one of these 3 methods, not sure if anyone knows:

1. Wireless. Signals travel through vacuum, which they require reflectors to turn, and use collisions to do logics. This is what most 2-state isotropic rules uses. Examples: Conway's Life, Dominoplex, Snowflakes.

Code: Select all

x = 16, y = 17, rule = B3/S23
14b2o$13bobo$15bo4$8bo$8b2o$7bobo6$3o$2bo$bo!

2. Inside wires. Signals travels inside wires, which could turn and do logics by bending and shaping the wire. This generally requires multistate to do so. Examples: JvN29, Codd's CA, B-Univ.

Code: Select all

x = 15, y = 3, rule = Codd
.13B$BA.GA.FA.EA.DAB$.13B!

3. Beside wires. Behaves like in wires, but signals travels at side of wires. Signals normally can transfer from a wire to another isolated wire. Small spaceships may exist in this rulespace. Generations and some 2-state INT rules use this. Examples: 1e2-a3-cij4kaijrtz5cnrq/2ce3aejnr4aj5y6a/3 (i.e. Silversmith's rule).

Code: Select all

x = 16, y = 5, rule = 1e2-a3-cij4aijkrtz5cnqr/2ce3aejnr4aj5y6a/3
3.BA.BA.BA.BA$16A$A14.A$16A$BA2.BA2.BA2.BA!

I think describing spaceships as drifters is more intuitive and consistent, compared to describing absence of any wire as a wire. Wireless communication is a thing.

True! I'm not understanding the comparison, though. Nobody in actual conversation has tried describing absence of any wire as a wire, right?

I haven't seen any examples of anyone trying to say "drifter" in conversation when they mean a spaceship, either -- have I missed any? "Spaceship" is usually the word to use when "spaceship" is what is meant.

The post I quoted was edited after my previous post.

That depends on your currently preferred definition of 'spaceship'. In particular, things that are essentially equivalent to spaceships were described as drifters in actual CA-related conversations.

Namely GOBWR (Generations On Black/White Reversal) rules.

The idea of GOBWR rules is that cells can't die within n number of generations since it was born, in which n is the number defined in the Generations rulestring.

Yes, ruletrees are definitely harder to create, but there are numerous scripts to convert ruletables into ruletrees.

Actually what you called "GOBWR" is already named "snoitareneG".

Also did you have any script(s) that converts ruletables to ruletrees? Post them in code tags.

Look carefully at the "snoitareneG" definition in its original post:

And here's the definition of GOBWR rules:

It's entirely a different thing!

Also there's one converter included in Golly (called RuleTableToTree.py):

Code: Select all

import golly
import os
from glife.ReadRuleTable import *
from glife.RuleTree import *
from glife.EmulateTriangular import *
from glife.EmulateMargolus import *
from glife.EmulateOneDimensional import *
from glife.EmulateHexagonal import *

# ask user to select .table file
filename = golly.opendialog('Open a rule table to convert:',
                      'Rule tables (*.table)|*.table',
                      golly.getdir('rules'))

if len(filename) == 0: golly.exit()    # user hit Cancel

# add new converters here as they become available:
Converters = {
    "vonNeumann":ConvertRuleTableTransitionsToRuleTree,
    "Moore":ConvertRuleTableTransitionsToRuleTree,
    "triangularVonNeumann":EmulateTriangular,
    "triangularMoore":EmulateTriangular,
    "Margolus":EmulateMargolus,
    "square4_figure8v":EmulateMargolus,
    "square4_figure8h":EmulateMargolus,
    "square4_cyclic":EmulateMargolus,
    "oneDimensional":EmulateOneDimensional,
    "hexagonal":EmulateHexagonal,
}

golly.show("Reading from rule table file...")
n_states, neighborhood, transitions = ReadRuleTable(filename)

if not neighborhood in Converters:
    golly.warn("Unsupported neighborhood: "+neighborhood)
    golly.show('')
    golly.exit()

# all converters now create a .rule file
golly.show("Building rule...")
rule_name = Converters[neighborhood]( neighborhood,
                                      n_states,
                                      transitions,
                                      filename )

golly.new(rule_name+'-demo.rle')
golly.setalgo('RuleLoader')
golly.setrule(rule_name)
golly.show('Created '+rule_name+'.rule and selected that rule.')

Look carefully at this B/W reversal of B37/S/C3, it's not GOBWR:

Code: Select all

x = 0, y = 0, rule = B12345678/S0234678/C3
A!

It actually is. The cell states in that rule is:
Yellow - dead
Dark red - alive and can die
Light red - alive, and always progresses to dark red in the next generation regardless of situation.

Cells are born in light red.

With all this information, watch it in very slow speed, and you'll find out that it does in fact meets the definition.

Actually, what you said and Saka said are synonyms rather than entirely different things - even if they're quite confusing.
In short, the cells take time to born and can't die (which takes space) until they're fully born.

There is one major difference:
In GOBWR rules, cells in the process of being born are treated as alive, and counts toward birth and survival.
In "snoitareneG" rules, cells in the process of being born are treated as dead, and does not counts toward birth and survival.

An example: GOBWR_Original (a GOBWR rule) and sgorF (a "snoitareneG" rule) both has the B3i transition,
but if one cell to give birth is in the process of being born, only in the GOBWR rule does the configuration actually works.

Code: Select all

x = 3, y = 1, rule = GOBWR_Original
ABA!
#C [[ AUTOSTART GPS 1 ]]

Code: Select all

x = 2, y = 2, rule = sgorF
ABA!
#C [[ AUTOSTART GPS 1 ]]

(However, in sgorF, the birth still works after all cells to give birth becomes red (which is the color for fully born cells.)
