Traffic Flow(2e3aciy4jnw68/S23678) - Turing complete and Geminoidable

[BokaBB]

This very rare oscillator looks conduity to me too:

Wow, great, thanks!
Here's a H into (2+1)G conduit:

$5b2o2b2o$5b2o2b2o$2b2o$2b2o$6b2o$5bo2bo$6b2o!

With some G support this could be used to rotate a reflector:

x = 8, y = 7, rule = B2e3aciy4jnw68/S23678
2b2o$bo2bo$2b2o2$6b2o$2ob2ob2o$2ob2o!

Turns 2 blocks into a G and a blinker:

R+H=2B+(2+1)G+A(googolplex's 3 blocks):

I'll stop here for now as to not destroy the joy of discovering to others.

Here's an useful-looking reaction:

$9b2o$2o7bo$2ob2o4b2o$3b2o!

This makes 2 blocks more distant:

$2bobo$2b3o5$b2o$b2ob2o$4b2o5$2b3o$2bobo!

I mainly used copy and paste to test different block positions untill I found something which was more stable, or produced another spaceship output.

[BokaBB]

Hey ya. Unfortunately I had no time to try splitters.

Can someone please make a black-white reversal of TF? I struggle to understand how's that done.

[BokaBB]

Hmm, I wonder if this is a new p2?

It's the 5th most common p2 oscillator in the D8_1 on catagolue.

Oh, oh, didn't pay attention much to that sector. I'm really sorry, please!
Could somebody make a black-white reversal rule of Traffic Flow? I don't get how to do it from LifeWiki.

Each birth condition in the original rule corresponds to a survival condition in the reversed rule, and vice versa. Where transitions in the original rule are added, transitions in the reversed rule are subtracted. The number on the original transition and the number on the reversed transition always sum to 8, and the letters directly correspond to each other (except in B4 and S4). For example, adding B3a would correspond to removing S5a.
The reversed equivalent of Traffic Flow, therefore, is B3478/S134-qry5-aciy6-e78.

[Chai]

Messing around with single channel operations a bit (useless, as we don't have a fast splitter), but found something that pulls a block an arbitrary distance:

I wrote a script in June that does that for you, provided that the universe is empty. The inverse is B3478/S134-qry5-aciy6-e78.

1. I don't know programming in any appreciable quantities (except for a few Excel functions and a few other scraps).
2. Thanks. Probably known already though.
3. Is there a chance for this rule to have a diagonal self-constructing spaceship without small diagonal spaceships? If not, I'd appreciate if somebody could try to look for some or teach me to do it myself.

[BokaBB]

Messing around with single channel operations a bit (useless, as we don't have a fast splitter), but found something that pulls a block an arbitrary distance:

Code: Select all

x = 4, y = 60, rule = B2e3aciy4jnw68/S23678
bobo$b3o34$bobo$b3o10$bobo$b3o7$bobo$b3o3$2o$2o!

We do have this fast failed splitter.

Code: Select all

x = 10, y = 12, rule = B2e3aciy4jnw68/S23678
$4bobo$4b3o6$2b2ob2o$2b2ob2o!

In fact, the reaction in the reflector is more or less based on it. Perhaps if we could manipulate this reaction we could have the fastest true splitter yet.

I found this modification that can recreate the missing block some distance backward in the same channel:

Code: Select all

x = 8, y = 16, rule = B2e3aciy4jnw68/S23678
3bobo$3b3o5$3bobo$3b3o6$b2ob2o$b2ob2o!

And this allows making a hive:

It can almost certainly be optimized.

[BokaBB]

So this is wonderful to see.

This is very simple, but a block can eat 2 spaceships at once:

Code: Select all

x = 8, y = 8, rule = B2e3aciy4jnw68/S23678
5bobo$5b3o4$2o$bo4b2o$2o4b2o!

This probably won't meet much use, but nevertheless this can sorta place 2 blocks close by:

Code: Select all

x = 10, y = 10, rule = B2e3aciy4jnw68/S23678
7bobo$7b3o6$2o5b2o$bo5b2o$2o!

3 simple ways to revert it to a block:

Code: Select all

x = 34, y = 18, rule = B2e3aciy4jnw68/S23678
$17bobo$17b3o8bobo$7bobo18b3o$7bobo$8bo2$3b2o14b2o$4bo3b2o9bo9b2o$3b2o
3bo12b2o6bo$10b2o9b2o8b2o$10b2o19b2o$17b3o$17bobo7b3o$27bobo!

More can be found pretty easily probably.

Sideways hits can destroy it and place a block forward:

Code: Select all

x = 6, y = 10, rule = B2e3aciy4jnw68/S23678
3bobo$3b3o5$2o$o$2b2o$2b2o!

Not painfully useful, but this allows shifting a blinker to the left and making 2G in the lane above the right spaceship's lane which are spaced enough that the two lanes don't interact:

Code: Select all

x = 9, y = 11, rule = B2e3aciy4jnw68/S23678
3o4b2o$7bo$7b2o2$3o5$3o$obo!

2 fast one-time 90° reflectors destroying a block:

Code: Select all

x = 16, y = 15, rule = B2e3aciy4jnw68/S23678
$10bobo$bobo6b3o$b3o4$2o$2o$4b2o3b2o$b2ob2o3b2o2b2o$b2o10b2o$10b2o$10b
2o!

[BokaBB]

This can turn a hive into a splitter and acts kinda like a splitter itself:

Code: Select all

x = 9, y = 12, rule = B2e3aciy4jnw68/S23678
2$4bobo$4bobo$5bo3$3bo$2bobo$2bobo$3bo!

This can turn a hive into a duoplet:

Code: Select all

x = 10, y = 9, rule = B2e3aciy4jnw68/S23678
$3bobo$3b3o4$3b2o$2bo2bo$3b2o!

This reaction might be useful for a splitter and similar stuff big time:

Code: Select all

x = 31, y = 12, rule = B2e3aciy4jnw68/S23678
3$3b2o$4bo$3b2o20b2o$19b2ob2ob2o$8b2ob2ob2o3b2ob2o$8b2ob2ob2o!

This is basically a factory of it:

Code: Select all

x = 10, y = 15, rule = B2e3aciy4jnw68/S23678
4bobo$4b3o5$2b2ob2o$2b2ob2o5$4b3o$4bobo!

Another one based on it:

Code: Select all

x = 41, y = 12, rule = B2e3aciy4jnw68/S23678
3$4b2o$5bo$4b2o$21b2ob2ob2o$12b2ob2ob2ob2ob2ob2o$12b2ob2ob2o!

The one-time splitter with an additional block can erase a block:

Code: Select all

x = 12, y = 8, rule = B2e3aciy4jnw68/S23678
$b2o$b2ob2o$4b2o$b2o6b2o$b2ob2o3bo$4b2o3b2o!

[Chai]

An extroardinarily dumb almost-splitter:

Code: Select all

x = 29, y = 37, rule = B2e3aciy4jnw68/S23678
2o27$22bo$22bo$11b2o9bo4b2o$13bo13b2o$11b2o$27b2o$27b2o2$25b2o$25b2o!

On a sidenote - Are there any very simple bait still lives that produce a hive when hit by a glider? The blinker and duoplet do produce a hive when hit in a certain way, but are not stable.

cvojan's catalyst is similar:viewtopic.php?f=11&t=4437&start=100#p98842

Do we have cheap ways of moving blinkers around?
I'd also like to highlight a recent discovery by me:

Code: Select all

x = 19, y = 8, rule = B2e3aciy4jnw68/S23678
$2b2o$3bo$2b2o2$7b2ob2ob2o$7b2ob2ob2o!

I think it's potentially useful.

[BokaBB]

Hey ya. I've just made a Discord server for Traffic Flow.
Invite:https://discord.gg/QpEsq7J5f3
I think it'll be useful. All explorers of Traffic Flow are encouraged to join, but it won't be a requirement.

[BokaBB]

I know this is known, but I'm just gonna show the capabilities of this reaction:

Code: Select all

x = 43, y = 17, rule = B2e3aciy4jnw68/S23678
7$3b2o2bo5bo3bo5bo3bo5bo3bo$4bo3bo3bo5bo3bo5bo3bo5bo$3b2o!

They can be even closer. If there's an easy way to make these, like a puffer, we could do some awesome things, such as allowing Chai's single-channel block mover!

EDIT: Unfortunately we can't due to the alternating parities of the spaceships.
