I wonder, if one can make a period 41 oscillator out of it.

Primarily I'm interested in the analyzer (raw gencols output would be interesting too). I'd like to contribute to development of the script, if you don't mind.

Regarding "some place" I would definitely recommend putting everything on GitHub.

I wonder, what structure your collision database has. Can you please make it available somewhere, e. g. via Dropbox or something? I'd be interested to try writing a script.

An interesting candidate

BTW: for one arcane reason I seem unable to find even the base reaction with gencols itself. I used something like gencols -pat herschel.life obj/glider.list -nph 4 -tc 5 80 -gen 80 -nosynch -test1 herschel79.life -filt ap (I tried all kinds of variantions with or without the -nosynch and with any ...

I found a helix .... Congrats! Very well done! It seems that you found a way to make use of g+3ss collisions. Just out of curiosity, have you tried to find a shorter helix for the caterpillar using the extended collision database? The next (fairly easy) step is to use the reactions of the original ...

I tried to reproduce effect of the basic reaction by using *WSS instead of a glider.

It WORKED!

Great idea! How did you find this collision?

There are two reactions that suppress a sideways glider by a sideways glider from a parallel track, that might be useful for track period adjustments.

Code: Select all

x = 30, y = 8, rule = B3/S23

For building the helix in the caterpillar they used a table of glider collisions with up to 2 standard spaceships. I wonder, if the helix could be made smaller if they used glider collisions with more spaceships, say, up to 3.

I am sorry that I did not make myself clear. I meant the distance between two input glider lanes there are, not the distance between gliders on the same lane.

I wonder, is the distance between input glider lanes chosen arbitrarily?

It doesn't work, and it's easy to prove it doesn't work. Suppose the spaceship we are talking about has a "classical" helix, i.e. one like that used in the Caterpillar. Then, over one period (79 generations), the Herschel/glider track moves up 23 cells but the spaceships in the helix move up 39. Th...

Whether it is awkward or not, there is no other known technology. E. g. the following LWSS salvo (given it is infinite) can be considered as advancing (23,5)c/79 to the north-east. A burning helix of this velocity consisting of standard spaceships, if it exists, should be easily constructible by the...

More investigation of possible (23,5)c/79 spaceship A caterpillar-like spaceship based on this reaction seems quite plausible.

Another idea for a master thesis or simply an article for a journal could be a program, that would generate a slow salvo recipe out of a glider synthesis.

That would be a real bridge between the large knowledge base of glider syntheses and spartan universal constructor technology.
