### Re: B2ein3cijn4cnrw5cnq6e7c/S1c2-ai3acny4anqy5c

Some reactions (including 90 and 45 degree reflectors) probably can be used to make guns and duplicator: x = 213, y = 248, rule = B2ein3cijn4cnrw5cnq6e7c/S1c2-ai3acny4anqy5c 74bo$59b2o14bobo$58bo2bo14b2o$57bo4bo$57bo4bo$58bo2bo$59b2o5$139bo$ 140bobo$141b2o$129b2o$128bo2bo$127bo4bo$127bo4bo$128bo2bo$...

### Re: PCA self-assessability?

could you work any "chaotic" CA as a TM? No. Think of white noise. 0/1 -> {0 (p = 0.5), 1 (p = 0.5)}. No information processing there. In my example I used the fact that it's almost deterministic. 'Does this road go to A.' ?" There is a bit difference. You can distinguish between consistent and inc...

### Re: PCA self-assessability?

Simplest example but a beat cheating - take a rule where some states are deterministic and some probabilistic. Say you have probabilistic signal that can die out with small probability but a deterministic logical operations on that signal. Now you want to create an output of A and B in form of A&B. ...

### Circle generating rules

During experimentation with isometric rules, I've discovered some of the rules are generating a perfect circle. An example (run for 5K generations): x = 7, y = 9, rule = B2cn3acekq4air5-acn7e/S12k3-jkn4airtw5acjnq6-ce78 3bo$bob4o$5obo$6o$4o2bo$7o$b5o$bobob2o$3bob2o! As the grid is square based I had...

### Re: Splitters with common SL

I wonder if it's worth doing an expensive test for stable reflectors, like cases where all the original cells remain but maybe there's some extra junk left over (that catalysts might be able to clean up)? It's idea similar to CatForce. I would say it worth a try, as it's very simple to write and mi...

### Parallel lifesrc search with genetic algorithm

lifesrc is implementing A* tree search specified for different CA to find spaceships and oscillators (or parents etc.). This is basically a tree search which tests unknown cells by converting them to 1 and 0 in some order. Another operation the search does is converting 1 or 0 into unknown and backt...

### Re: Simplified Demonoid in CGOL

"Scorbie's Demonoid" design It's basically the same design (I've somehow forgot about Scorbie's Demonoid), just with single conduit or with P30. You can say it's just a variation on the same theme, I probably will use *WSS for the destruction but it's a nuance. I guess the competition is with Scorb...

### Re: Simplified Demonoid in CGOL

I did some rough measurements. The p30 construction arm in Remini seems to realease a glider approximately every 6000 ticks. For single arm construction it appears to be around 3600 ticks. The construction arm in the 0hd-Demonoid releases a glider about every 800 ticks. Have you taken into account ...

### Simplified Demonoid in CGOL

Simplified Demonoid is a Geminoid with a single duplicator. This duplicator outputs allowing the twin to be just flipped 180 degrees. Example of this design are coming from other CAs. See here and here . In CGOL the simplest designs of the relevant duplicator are: x = 78, y = 62, rule = LifeHistory ...

### Re: Modifying geminoid to reach any speed < c/2

How hard would it be to make the ship travel in arbitrary directions as well It's not much harder. One just need another horizontal blinker puffer + MWSS reflector to be encoded in the tape. When the first vertical blinker puffer is converted to SL, the next part of the tape will build the same mec...

### Re: Modifying geminoid to reach any speed < c/2

Can't you just construct the blinker puffer, then wait a long time, and then ignite the trail? I don't see the reason for having the extra *WSSes which stop the fuse and reignite it later...? Helix is better in places where you want to send several helices in a row to move the same SL. I don't thin...

Can you expand on this? What's a universal helix? What do you mean by a quadratic time delay? Universal helix is a pattern that allows to place still life at any desired distance D with construction cost of O(sqrt(D)) and speed arbitrary close to c/2. x = 62, y = 548, rule = B3/S23 46bo$39b3o3b3o$3...

### Re: 3D Geminoid challenge

26 neighbours seems too much to handle. I don't think it's too much to the contrary I would have a totalistic rule even more fine tuned for different types of neighbors (common edge, vertex and face). Maybe we should come up with a 3D von-Neumann totalistic rule instead? von-Neumann totalistic rule...

You seem to be plannyng way ahead of time considering your first step is to find a 3d rule with incredible capabilities.

### Modifying geminoid to reach any speed < c/2

The design below is probably the simplest way to construct a universal speed orthogonal spaceship for all valid speeds i.e. <c/2. We start from regular Geminoid. In usual Geminoid the snake of a signal makes one loop and reaches a new copy. In our case the snake is done twice. First time for copy co...
