Here is a Cordership based pseudo-random rake.

Code: Select all

#C A diagonal c/12 pseudo-random sideways glider rake.
#C A loop is formed using boats and forward gliders, where new
#C gliders are possibly injected into the loop using an XOR
#C operation from gliders copied from two locations within the loop.
#C The size of the loop can be changed by shifting the top left
#C spaceship by a multiple of 32 cells, which can change the
#C period of the pseudo-random output stream.

Someone could investigate what change would make the longest random sequence. The rake shown above seems pretty good with no obvious pattern to me, but I have a feeling that the sequence is not as long as it could be.

EDIT:

Thanks to ktT for a new boat detection reaction, I can make a nicer pseudo-random rake.

Code: Select all

#C A diagonal c/12 pseudo-random sideways rake.
#C A loop is formed using boats and forward gliders, where new
#C gliders are possibly injected into the loop using an XOR
#C operation from gliders copied from two locations within the loop.
#C The outer loop of this particular rake contains 107 gliders.
#C The size of the loop can be changed by shifting the top left
#C spaceship by a multiple of 16 cells, or by shifting the middle
#C rakes by a multiple of 16 cells, which can change the full
#C period of the pseudo-random output stream.
#C This is a improvement on a previous version of the rake,
#C using period 96 components instead of period 192 ones.

!

The number of gliders in the loop can be adjusted by multiples of 3. But I can't get the loop size to be one less than a power of two as desired for a maximal period.

I figured 107 is next best since it is prime. Even so, the output seems to have more gliders than gaps, so the randomness is not as good as I would like.

The spark seems pretty useful; it is the first 2c/7 dot that can interact with a 2-cell edge in a way that causes a birth of two cells and also has some edge-repait ability due to lots of overpopulation.

For example, it allows the p105 rake to be reduced:

I’m going to point out the obvious, it’s not technically a new spaceship, just an old spaceship with a tagalong.

[Sokwe]

it’s not technically a new spaceship, just an old spaceship with a tagalong.

I would argue that combining a spaceship with a tagalong makes a distinct spaceship. I'm not aware of a widely accepted term that differentiates between spaceships with and without tagalongs, but I personally tend to use "basic spaceship" to refer to spaceships without tagalongs.

[Entity Valkyrie 2]

Just wondering, are there any known c/2 period-62 block puffers (or period 62 or 124 rakes), ideally reasonably constructible?

EDIT: The main reason why I asked about p62 block puffers (or p62n rakes) is that if we have a way to lay one block every 31 cells, we can have a puffer construct a 31c/240 track

The contents of Sokwe's jslife-moving repo, jslife-moving/velocity-c2/c2-extended/c2-0062.rle, don't seem to offer a lot of hope for known-reasonably-constructible at p62:

Has anyone tried this search yet: 3c/11o symmetric, start with two traffic lights near the edge. Different spacings would be possible. I believe this would have a larger width than any "unseeded" 3c/11o.

This is essentially "random fill" rather than anything representing a partial, but it shows how the traffic lights would move.

I would also like a search on this 2c/9o that I've mentioned before. In this case, the existing mechanism would have to be in the center, while the search program would put cells symmetrically on the side. By default, this is a blinker puffer engine (and the exhaust interacts with itself but doesn't destroy the engine), not a clean spaceship, so make sure to include those solutions.

Here is a very slow growing spaceship.

Code: Select all

#C A growing diagonal spaceship whose back end moves very slowly.
#C The spaceship has a bounded population (around 5000 cells),
#C but has a growing bounding box.  The front part is made of
#C Corderships which when triggered produce a convoy of three
#C backward gliders aimed at the back part which just a single block.
#C The glider convoy pulls the block closer by one diagonal cell
#C while releasing a forward glider to trigger the next cycle.
#C The front end moves at c/12 but the back end moves at an
#C exponentially slower speed.

The tricky part of this spaceship is that the returning gliders from the block pull reaction have eight different timings that have to be detected. One of my sparking spaceships is able to detect one of the timings to produce a glider without affecting the glider in the other timings. So with eight such detectors in a row I can handle all the cases.

I plan on packing the parts closer together, but I thought it would be easier to see how it works in this original version.

EDIT:

Here is a packed version of the slowly growing spaceship.

Code: Select all

#C A growing spaceship whose back end moves very slowly.
#C The spaceship has a bounded population (around 5000 cells),
#C but has a growing bounding box.  The front part is made of
#C Corderships which when triggered produce a convoy of three
#C backward gliders aimed at the back part which just a single block.
#C The glider convoy pulls the block closer by one diagonal cell
#C while releasing a forward glider to trigger the next cycle.
#C The front end moves at c/12 but the back end moves at an
#C exponentially slower speed.  This is a packed version of a
#C previously shown growing spaceship.

This is not the absolutely best packing possible since I didn't try to squeeze out all of the space between the back spaceships.

That would be much better for crawlers than spaceships themselves, as oscillators can have mirror symmetries of any slope whereas spaceships can only have symmetries either orthogonally or diagonally.

They seem like they would have been found by the above searches but they weren't included.

Sokwe has added them to LifeWiki CurrentNews as "a pair of 2c/7 spaceships" that are "tied as the third smallest known 2c/7 spaceships, after weekender and doo-dah". That's pretty good evidence that these were not found in previous searches, for whatever reason.

It's actually a trio and not a pair, though -- the third option is to break the symmetry:
