Re: Introductions

Hello everyone! I decided to join this forum because some Anon from /sci/ and I discovered a new (at least I think it is) and very interesting cellular automaton which we called Xor-life , and I hope that I will have enough time in the next couple of days to give a detailed report on this. We are f...

Re: (2,1)c/6 technology thread

14-engine true p36 rake... Here's a reduction to four or five engines for the p36 rake, depending on whether you want NE or SE glider outputs, or both: x = 441, y = 522, rule = B3/S23 10b3o$9bo2b2o3b5o$9bo4bob4o3bo$12bo3bo$9bo10bo3bo$9b2obo2bo2b2o4bo$9bo 4bo2bo$4bob2o10bo4bo$3b2o5bo3bo5bo$2bo3bo3b2...

Re: (2,1)c/6 technology thread

It turns out that cleaning of my p60 rake can be done with just one Sprayer... There seems to be a fairly enormous search space, just with one Sir Sprayer interacting with a p12 block puffer/backrake collision. All kinds of different multipliers show up very quickly. It might be about time to stop ...

Sure -- when questions need answering, do whatever you have to do to answer them!

(In this case, though, you could just post a link to Golly's online help document.)

Re: (2,1)c/6 technology thread

Edit: p24 rake... Jormungant already posted a p24 rake with different technology (and a different output direction, but it's easy to use it to make a backward rake too). But it looks like yours is a bit more compact. Here's a side-by-side comparison with both versions tightened up a bit -- Jormunga...

(2,1)c/6 glider ping-pong 1o1: x = 2994, y = 2107, rule = B3/S23...

Re: Four new almost-knightships CGOL

That means we have two elementary knightships now, and one extensible one. Great job calcyman! It seems to me that Sir Robin is also extensible, in a couple of ways (via knightwave connections and direct connections between multiple Sir Robins). See the Other Spaceships section of the Sir Robin Lif...

Re: Four new almost-knightships CGOL

Does that count as a new Knightwave then? Sure -- a ridiculously complex knightwave compared to the other one, but I guess it's still a knightwave. It can be thought of as traveling obliquely at (2,1)c/6, orthogonally at 44c/357, diagonally at 88c/807, or lots of other weird oblique velocities. x =...

Second one, F for flip, R for right, L for left, B for back(?) Cancel that, please! Capital F has never stood for "flip" -- it means "Forward". In modern conduit syntax, "x" means "flip". In the 1990s a small "f" was also used for "flip", but that went out of style by the time Karel Suhajda's Hersr...

Re: How about a direct highway robber?

It's kind of odd that we don't have a small highway robber yet--a p1 pattern that acts as a glider eater on one lane, but lets gliders pass completely on an adjacent lane and all further-away lanes. That description doesn't quite line up with my idea of " highway robber ". A highway robber has to b...

Re: Multiple Neighborhood Cellular Automata (MNCA) - Slackermanz

It's the equivalent of defining n LtL custom neighbourhoods and then applying them in sequence to get the final cell state. For the most simple implementation variants, this is correct.

As for use cases involving all cell states, we could for example use it to annotate a theoretical period-19 gun or something which can only be constructed using special cells.

If we follow the usual guidelines, the discoverer gets to name the discovery. Makes sense, but what about the object being hassled? Good point. I won't venture an opinion about that.

I think we should probably decide on an official name for the object first. "U-turner" always makes me think of something turning a "U".
