This rule is almost certainly Turing complete. You can build blocks, delete them, use the blocks to multiply signals or to block them. Signals are 1D-extensible

It would be nice if there was a transition allowing signals to place blocks in a way that bypasses the bounding box limit and the bounding diamond limit (Universal construction)

Can you think of an example reaction? Preferably allowing all the previous ones in the showcase.

EDIT: Minor update to the rule, updated in the first post.
These reactions are now allowed:

Code: Select all

x = 40, y = 11, rule = FreeElectronics
40C9$17.A.A17.A.A$17.B.B17.B.B!

Reason: until now, 1xn polyominos for n>3 were indestructible; this can allow "for" loops and that sort of thing, and using the 1xn building reactions and these new ones can allow new stuff

----------------------------
Glider-constructible filter:
For length=2 signals, emits the original signal together with an auxiliary length=1 signal, but, for more than one input signal, it has different behaviours. With d = distance between the photons:
d=2 and 3: emits 2 photons and one auxiliary signal
d=4 to 12: emits one photon (of the original two) and one auxiliary signal
d=13 to 26: emits one photon (of the original two) and two auxiliary signals
d=27 to 31: emits one photon (of the original two) and one auxiliary signal, but further forward than with d=4 to 12
d>=32: signals are independent, i.e. every original photon gets transmitted and for each original photon, an auxiliary signal is sent

I just wanted to bump this rule again in case...
1) someone wants to implement the universal-construction reaction without destroying all the other dynamics of the rule
2) someone wants to attempt a Toffoli gate potentially starting with this OR gate:

There already is a block-pushing move (it's in the first post in the RLE with the set of reactions).
EDIT: I'm clearly wrong. Sorry.

Posted: **March 9th, 2018, 7:44 am**

There is no pushing reaction, only creating blocks.

For single blocks, with one more state A (the "push ether"), upon "pushing" you can get a block surrounded by 5 cells in state A (5i neighbourhood). Then, 5i block dies and the cell with the following neighbourhood becomes a block:
(A) A 0 0 --> (0) 0 0 0
(A) X 0 0 --> (0) 0 X 0
(A) A 0 0 --> (0) 0 0 0

I think this works. EDIT: Here it is:

Just making sure.

Is there any easy way to synthesise diagonals?
Here was my attempt:

Code: Select all

x = 118, y = 242, rule = FreeElectronicsX
18.B$18.A20$17.B$17.A20$16.B$16.A20$15.B$15.A20$14.B$14.A9$115.AB$13.
B81.AB$11.B.A60.AB40.AB$11.A44.AB38.AB$38.AB35.AB$20.AB35.AB$39.AB$21.
AB3$13.A$11.A.B$11.B7$14.A$14.B18$15.A$15.B18$16.A$16.B18$17.A$17.B18$

AB!

(also with a splitter gun synth for fun)
