Glider/**SS Reactions

Post by Jackk » March 13th, 2012, 8:24 pm

Hi, I'm a long-time lurker who has "played" with CGOL for about a year. Recently I have been particularly interested in flyby reactions, and below is a "chain" reaction. I just wondered whether I have inadvertently discovered any new mechanisms.

*Disclaimer - I developed this independently and discovered all these mechanisms on my own. However, I do not take credit as being the first one to find these mechanisms. Any or all of these may have been discovered.*

a) P48 Schick engine backward rake
b) Backward glider - pre-traffic light - forward glider
c) forward glider - mess - 2 forward gliders
*unknown puffer engine here - cannot find on Lifewiki
d) 2 forward gliders - 1 forward glider
e) forward glider - pre-traffic light - forward glider
f) forward glider - mess - backward glider
*Coe ship used
g) backward glider - loaf - forward glider
h) forward glider - B-heptonimo - pre-traffic light - forward glider
i) glider - 0

Code: Select all

x = 451, y = 185, rule = B3/S23

Hi.

I don't recognise these mechansims from any pattern i've seen so you may have discovered them. These do have a potential to be used in a larger mechanism or to what I've noticed if you remove the last MWSS it creates a p48 rake (predessesor). Frankly though, I would be suprised if these weren't discovered. Still these are nice reactions to find even under ones own power.

Another reaction

This is probably redundant, but I've been tinkering with the B-heptonimo possibilites, and found this 4-spaceship glider turner (forward - back). I just liked how the glider is formed very early on (is it the normal first emitted glider of a Herschel?), and the debris vanishes to a block, even removing the original block produced by the B-heptonimo.

forward glider - B - Herschel+block - backward glider+mess+block - backward glider+block - backward glider

Code: Select all

(a) p48 back rake, using a Schick engine
This is larger than known technology; see the c2-extended/c2-0048.lif file in my jslife collection.
But the glider release position (at the side) is good, and maybe it could be optimized.

(b) B(ackward glider) -> F(orward glider), same side, using 3 *WSS
Huh. This should be jslife:velocity-c2/turners-c2-p4-b.lif, but seems to be missing. The mechanism is known, though, and it appears in jslife:misc/flyby-toglider.lif.

(c) F -> 2F, opposite side, using p8 spaceship + 2 *WSS
(d) 2F -> F using MWSS
Cute, though very specialized.
The p8 spaceship is known; see jslife:c2-extended/c2-0008-ss.lif.

(e) F -> F, opposite side, using 3 *WSS
This is in jslife:velocity-c2/turners-c2-p4-f.lif (in an optimized form).

(f) F -> B, opposite side, using Coe ship + 3 *WSS
(h) F -> F, same side, using 5 *WSS
These are probably too expensive (too many *WSSs) to be of much general interest.

(g.1) B -> loaf, using LWSS

(g.2) loaf -> F, using 3 *WSS
This is in jslife:misc/flyby-toglider.lif, in a slightly different form.
Efficient "flyby" reactions, where a stationary object is turned into another object, are of some interest (to me at least). It would be nice to have a bigger collection of them.
