### 1-Dimensional Patterns

Posted: March 5th, 2014, 10:53 am
For all patterns that are only 1 cell thick!
Do all patterns have a 1-cell-thick-parent? (This includes junk that doesn't interfere with said pattern- for example, since a one cell thick is vertically symmetrical, what's above is the same as what's below.)
One-cell-thick patterns can cleanly create gliders for syntheses, etc, so I was thinking we could make a thread for the most interesting ones.

One-cell-thick infinite growth:
x = 39, y = 1, rule = 23/3
8ob5o3b3o6b7ob5o!

What do we want to accomplish with one-cell thick patterns?
To start, glider syntheses would work, so we have a few questions:
1) What is the smallest one-cell-thick pattern that creates gliders?
2) What is the smallest one-cell-thick pattern that is a PURE glider generator (that is, creates gliders and nothing else?)

Some research on this question is published here.

That's a tougher one -- at least I haven't seen very many one-cell-thick patterns that emit gliders without leaving piles of junk. Maybe Paul Callahan's 66-cell diehard could be adapted somehow to let a glider or spaceship out?

Mm, clearly we can take just half of that:

x = 39, y = 1, rule = B3/S23
6ob4ob3ob7ob5ob4ob4o!

to purely make gliders and LWSS's.

Adding a nice beehive predecessor to the right as shown:

x = 61, y = 1, rule = B3/S23
6ob4ob3ob7ob5ob4ob4o18b4o!

Could compact syntheses as it creates more gliders without the need for an entire new set of 33 cells.

Lastly, I give a real quick predecessor (5-1-5) of the pulsar. It may be obvious, though..
x = 11, y = 1, rule = B3/S23

x = 19, y = 1, rule = B3/S23
4o3b12o!

A 16 cell, 19-wide pattern that produces a couple gliders- two heading diagonally to the upper left, and two heading diagonally downwards left from a good distance that may be used in syntheses.

x = 94, y = 1, rule = B3/S23

Looks good... The really nice thing would be a couple of different pure *WSS generators, which could then be collided to produce a universal construction toolkit, along the lines of the solution for two-cells-thick patterns.

But I suppose the quadratic-growth pattern already has all the required pieces to solve the universal-construction problem -- just a lot messier than the 2xN case, is all...!

How about using only PURE 1D glider generators for universal construction?

You'd need a lot more clean 1D glider generators with slightly different timings, I think. As far as I can see, the current clean 1D reactions don't allow for putting gliders one behind another on nearby lanes, and it seems like that will be needed to produce clean *WSSes. At least I don't see how to do it with glider kickbacks...?

The usual trick is to collide gliders to produce lots of *WSSes on nearby lanes, and then collide those to make a couple of slow glider streams with arbitrary timing... and then collide those to build whatever object you want to build.

-- When I write it out, that sounds like a lot of work! But it's a lot harder if you can't build the *WSSes without leaving junk all over the place.

Four pure gliders:
x = 56, y = 1, rule = B3/S23
4o5b8ob4ob3o4b3ob4ob8o5b4o!

This uses a basic 3-4-8 pattern that needs cleanup.

Two gliders for roughly half the size:
x = 24, y = 1, rule = B3/S23
3o2b8ob5ob4o!

Found it while randomizing a 100x1 rectangle at 80% density. (That 80% number can be varied somewhat.)

I tried to put two of these together and I realized that the distance between glider generators doesn't matter:

x = 168, y = 1, rule = B3/S23
4o5b8ob4ob3o4b3ob4ob8o5b4o88b3o2b8ob5ob4o!

x = 94, y = 1, rule = B3/S23
4o5b8ob4ob3o4b3ob4ob8o5b4o14b3o2b8ob5ob4o!

the gliders are the same distance from each other upon approach.
So, it's how long it takes for these gliders to be generated that's an important factor.

I've been censusing B3/S23 in 1x256X2+1(two axes of symmetry, one from the 1-cell-thick nature of the pattern, and one artificial), does anyone want to help me? There's a VERY HIGH OBJECCT YIELD!

Following Wojowu's post here, a nontrivial unidimensional pattern that evolves into another.

x = 77, y = 1, rule = B3/S23
11ob4o2b4ob3o6b6ob3o2b9ob3ob3o7b5ob3o!
[[ STOP 128 ]]

I spent about a week searching for this purposefully, by way of near-brute force, after figuring out how to make some VERY amateur modifications to bgolly and a pair of similarly amateur C++ "search" programs: one to find an inward-bound glider pair generator (right), and the other to find an appropriately-timed blinker edge-shooter (left). This final result, however, came about by virtue of sheer dumb luck (and a frantic few minutes of manual fiddling in Golly), and as such I'm sure there's a more optimized solution to be found if one were interested enough to properly search for it.

But it's at 90 degrees!

Still evolves into a 1-cell thick pattern. If you want one that's parallel, here's one (See generation 9):
x = 48, y = 1, rule = B3/S23

From this post.
It can be extended, too:
x = 80, y = 1, rule = B3/S23

Oh!
I definitely saw this when you posted it (back when I visited these forums regularly). This time around I had a faint memory of it, but after finding no mention of it on the wiki page
Wiki (~1 year out of date as of Aug 21) wrote:A weaker problem is to find a unidimensional pattern that is the predecessor of another non-trivial unidimensional pattern.
– and no results from the forum search, I chalked it up to misremembering Wojowu's speculation as a full solution and went ahead with my own search.
Congratulations, however! I suppose my find is still interesting as a novelty, if nothing else...
