It sounds like there is a need for a searchable database with an index keyed to the Hickerson Rotor Descriptor.

User enters in an oscillator in RLE or apgcode format. The interface or server/backend calculates the HRD and retrieves all the oscillators that match. Display graphically or provide RLE or provide list of apgcodes.

I see a LifeCodex page on your site http://pentadecathlon.com/LifeCodex/LifeCodex.php that mentions HRD, and also WCode. Are these terms formally described anywhere? if the conversion process is straight forward enough, I could add support for them in my database (I've already added the mechanism to support APG and SOF).

Mostly a case of "creating my own terminology". The Wcode is just the apgcode without the prefix. I find the prefix gets in the way and is redundant for entries in the databases I've set up. The "HRD" or Rotor Descriptor is just the encoding that Dean Hickerson came up with years ago, that he used in "dr" and is the basis for the "knownrotors.txt" file. From the documentation--
A rotor descriptor is a compact, but human-readable, description of the
rotor of an oscillator. It shows the size and shape of the rotor, how
many neighbors in the stator each rotor cell has, and what gen 0 looks
like. For example, the rotor descriptor for aVerage (LifeLine 9.3,
SC 5.1.2) is:

p5 r9 3x5 .2..B 30@@@ .2..B

The first 3 'words' mean period 5, with a rotor consisting of 9 cells in
a 3x5 rectangle. (The orientation is always chosen so that the rectangle
is at least as wide as it is tall.) The rest of it is a picture of the
rotor in one generation, with each word representing 1 row:

.2..B
30@@@
.2..B

The characters other than periods indicate rotor cells. Digits 0 to 3
indicate cells that are dead in gen 0; characters '@', 'A', 'B', and 'C'
indicate live cells in gen 0. (If you're using a rule other than Life,
you may see digits larger than 3 and letters after 'C'.) If you change
'@' to '0', 'A' to '1', 'B' to '2', and 'C' to '3', you get:

.2..2
30000
.2..2

Each number tells how many live neighbors that rotor cell has in the
stator. With this information, it's fairly easy to determine what
the rotor looks like in every generation, without having to construct
the stator. (Finding a minimal stator is still pretty tedious, even
with the help of lifesrc.)

A given oscillator will have many different rotor descriptors: You can
change the orientation and choose which phase is gen 0. The program
computes all of them and chooses the one that's lexicographically
smallest, with '.' < '0' < '1' < '2' < '3' < '@' < 'A' < 'B' < 'C'.

The file "knownrotors" contains a list of rotor descriptors and names
of oscillators. Usually these are given on 1 line, with 1 or more tabs
in between. But if the rotor is large, then the rotor descriptor can
have carriage returns within it or after it. (The spaces must still be
present.) The name must fit on 1 line. For example:

p3 r7 3x4 .1.C A.A. 1A1. protein (DJB #6)

p4 r28 7x7 .1.0.1. A.101.A .A.@.A. 0@@.@@0 .A.@.A. A.101.A .1.0.1.
monogram (SC 4.0.2)

p14 r24 8x9 ........3 ....A.A.1 ...10@@1. ...3.21A. .AA....3. A.1......
0@@2..... B.A...... new 14.0.1

The name usually contains a reference to where the oscillator can be found,
either in the stamp collection ("SC"), or in David Buckingham's oscillator
collection ("DJB #"), or in the collection of billiard tables found by
dr.c ("new").

New Period-116, Period-232 oscillators using four Snark's (each)

Post by LeoTheMiner_12 » June 27th, 2021, 12:55 pm

It is possible to make, using any variations of the Snark, to create an oscillator of period-232, -116, another -232, and -58 oscillator by putting 1, 2, 3 or 4 gliders respectively in this loop:

Code: Select all

# shown for 2 gliders (Period-116):
# using 4 variants of the Snark;
x = 51, y = 52, rule = B3/S23
#C [[ GPS 48 ZOOM 6 LOOP 116 ]]

Re: New Period-116, Period-232 oscillators using four Snarks (each)

Post by dvgrn » June 27th, 2021, 1:18 pm

This is a commonly-used trick to reduce the period of many oscillators with signals traveling in a loop. See for example many of the guns in the glider guns thread.

It doesn't have to stop with 4 gliders. Moving the Snarks farther apart changes the total length of time needed to traverse the loop, and if the new length is divisible by any number N, then you can put N equally-spaced gliders in the loop (as long as the distance between gliders doesn't get reduced below 43).

I've moved this series of posts to the "unsure discoveries" thread, since it doesn't seem to need its own thread.

This is a commonly-used trick to reduce the period of many oscillators with signals traveling in a loop. See for example many of the guns in the glider guns thread.

I've moved this series of posts to the "unsure discoveries" thread, since it doesn't seem to need its own thread.
Okay sure that makes sense :)

Is this slow component known?

Code: Select all

x = 11, y = 16, rule = B3/S23

Use 10 cells (two gliders) to add nine cells? Sure doesn't look familiar to me. That size of addition with only two gliders is pretty unusual, isn't it?

Yes, but that is a paperclip-like motif, which is fairly common. Also, I found a niche fast component for it.

Code: Select all

x = 19, y = 17, rule = B3/S23

I'm getting some promising signs for using a supported one-cell tip instead of (the equivalent of) an unsupported dot spark.



Edit: I found a very promising partial (as in I haven't figured out how to synthesize that region or an equivalent yet) on a different line of approach).

Code: Select all

x = 11, y = 11, rule = B3/S23

Another edit: Is this converter known?

It looks like it might be useful for Snark syntheses.

I knew about it because it's a child of one of the two sparks you posted on Discord:

Code: Select all

x = 47, y = 10, rule = B3/S23

Might as well post here the results of some investigations about reducing the Snarkmaker. In the end, slow-salvoing an inline Snark with this converter came out slightly more expensive than the current recipe (113 gliders vs. 99 gliders):

Mileage may vary for other equivalent startup constellations, and the cost analysis may definitely be different for non-slow-salvo recipes.
