Create your own terminology

[dvgrn]

the draft for a wiki article

It's a bit early for an article, according to standard LifeWiki practice for new terminology. In the article you mention a lack of references, and there's a reason for that: the term "clarint" can't possibly have very many references yet, since it was only invented a couple of hours ago.

In a year or so, if "clarint" has gotten widely adopted in conversations to the point where someone can use it in a conversation and expect to be understood by the rest of the community, then it might be time to move that article to the main namespace -- since in that case there will be references that can be added.

If that doesn't happen, please try not to be too disappointed, and please don't try to force-start conversations just to use the word so that it can be a reference. Artificial uses like that aren't going to be valid references.

If a forum search is any guide, people just don't really need to talk about obobo sparks all that often. If nobody talks about obobo sparks, they don't need a separate LifeWiki article. And it seems like there might be a good argument that "obobo spark" is a lot clearer than "clarint spark", anyway -- "obobo spark" is used in the proposed definition, after all.

[hotdogPi]

The only time I've seen an obobo spark naturally is this 3×2:

Code: Select all

x = 5, y = 5, rule = B3/S23
b2o$o2bo$o2bo$bo2bo$2b2o!

Edited 1 hour later: I call this "boxcar". It mainly applies to the sequence rather than the spark it creates, though.

And it seems like there might be a good argument that "obobo spark" is a lot clearer than "clarint spark", anyway -- "obobo spark" is used in the proposed definition, after all.

obobo spark was used to define clarint spark, not to be its name. unfortunately, some people are going with obobo anyways and its in my article now that some people call it obobo spark.

New type of clarint spark:

Code: Select all

#R B3/S23
obo2$bo!

Spatial period

A wick or agar has spatial period (m,n) if it is the same when shifted by (m,n).
A storage system has spatial period (m,n) if shifting the storage by (m,n) gives a valid piece of information that can be retrieved.
A metacell has spatial period (m,n) if it functions properly when tiled with displacement (m,n). The term is called cell size on LifeWiki, which is equivalent to spatial period for orthogonal metacells like OTCA or p5760 unit Life cell, but non-equivalent for diagonal metacells like 0E0P Metacell.
More generally, a De Brujin diagram has spatial period (m,n) if it becomes a periodic Markov chain with period p when transitions are given positive probabilities, and p steps on the De Brujin diagram always correspond to a spatial displacement of (m,n).

The term is fundamental for wicks (a pattern with a spatial period) and agars (a pattern with two independent spatial periods), and useful for storage in universal construction systems, e.g. the storage in the Stable Storage Spaceship has spatial period (24,24).

I think that example doesn't count as a hassler. The reason is different. If you just remove the beehive from the pattern, then the remainder disintegrates (fails).

The supporting objects need to evolve in "essentially the same way" regardless of whether the hassled part is present or absent. The provided example fails this test.

Here are two proposed terms:Please note that confocaloid is on my ignore list. I will not continue to respond to them.

• Independent hasslers are hasslers where, if the object (e.g. a beehive) is removed, the supporting the oscillators do not disintegrate.
• Dependent hasslers look like hasslers, but if the object is removed, the supporting oscillators disintegrate.

pattern from my sandbox

[confocaloid]

bounding-lined in is used to describe a pattern that cannot move in one or more directions. it is only applicable to anisotropic rules. [...]

Why the restriction? Wouldn't (for example) any pattern in S023458/B457 count as "bounding-lined in" otherwise?

Code: Select all

#C [[ RANDOMIZE ]]
x = 1, y = 1, rule = B457/S023458
b!

Also, are there good examples of patterns with that property in cellular automata where some other patterns lack the property?

[hotdogPi]

Take a B1e rule that follows 2x2 block emulation. If it's in 2x2 form, there will be a diamond that can't grow but the inside looks random. However, place one cell anywhere, and unless it "corrects" itself, it will start expanding at light speed.

[confocaloid]

The following should count as an example of that; I wanted to check the intended meaning of "a pattern that cannot move in one or more directions".

Code: Select all

[hotdogPi]

Yes, that looks good.

That said, I'm not the one who created the term.

[tommyaweosme]

Yes, that looks good.

That said, I'm not the one who created the term.

all of those are bounding-boxed/diamonded in.
it is specifically referred to use when it cannot grow in one or more directions, but using the term to refer to four would be a waste because you can use either of the above.

Sharp catalysis:

Code: Select all

x = 6, y = 4, rule = B3/S23
o$2o$3ob2o$4b2o!

Code: Select all

x = 7, y = 4, rule = B3/S23
2o$3o$4ob2o$2o3b2o!

Blunt catalysis:

Code: Select all

x = 7, y = 3, rule = B3/S23
b2o$o2bob2o$b2o2b2o!

Code: Select all

x = 6, y = 4, rule = B3/S23
o$2o$2bob2o$2o2b2o!

This is primarily intended for block catalyses but can probably be used for other catalysts.

[confocaloid]

Seems unclear. Is there some sort of measurable/detectable property that is intended here ("sharp", "blunt")? If so, can you define the properties? Or this is supposed to refer to some specific catalyses (in that case, what is important and what is irrelevant)?

Sharp catalysis: [...]
Blunt catalysis: [...]
This is primarily intended for block catalyses but can probably be used for other catalysts.

[hotdogPi]

I think the intent is to look at the three columns closest to the block (two if you exclude the empty one). That said, the two "blunt" ones work differently.

[CARuler]

my notation (x,y;z) (or (x,y;z)-(y,x;z)):
( for the sake of this definition assume n and m are arbitrary nonzero natural numbers such that n≠m)
the notation (x,y;z) is designed to represent a group of equitant neighborhoods;
you can represent a cell in a neighborhood as a vector where the cell the neighborhood is centered on is the origin [0,0],
one thing i noticed is that cells on vectors in forms of ±[a,0],±[a,a],±[a,b](|a|≠|b|) have different symmetries,
so i deiced to make a notation (x,y;z) means there are x cells that can be represented as a vector in the form of [n,0], y cells that can be represented as a vector in the form of [n,n] and z cells that can be represented as a vector in the form of [n,m] (assuming D8 symmetry)

Gliderless glider gun: a bit confusing, but it means that no extra gliders are used to make the glider stream. This usually excludes pseudo-period glider guns that injects gliders into the glider stream.
Therefore gliderless pseudo-period glider gun means that the engine is true-period, but there's something like catalyst that multiples the period.
This is an example:

Abbreviating the e9jp as Y (but not properly naming it) randomly popped into my head one day. However, I’m also proposing the sequence on the right be called Y’ since the e9jp evolved into it plus a spark, but all e9jp conduits I know of don’t interact that late:

Semiomniperiodicity: An alternative of omniperiodicity.
If all periods are proven impossible or possible, then the rule is semiomniperiodic.
For example, B/S and B/S012345678 are semiomniperiodic, because all periods are impossible.
WireWorld is semiomniperiodic too, becuase It has every period other than 2 and P2 is impossible.

The concept "omnivelocital" needs further discussion.

EDIT: As confocaloid says, '"every CA is semiomniperiodic'" according to above.
I agree with him/her and changing the definition to

existence of oscillators of every period in such-and-such cellular automaton is a solved problem

A rule with every speed seems impossible unless it has infinity states (and therefore we can hack like photons10 infinitely).
