@wildmyron: Below are the only lines that favor left turn cells over right turn cells. 0,17,1,i,m,e,k,j,4,2 0,17,4,i,m,e,k,j,1,5 4,17,a,b,c,d,e,f,g,6 6,p,a,b,c,d,e,f,12,16 6,p,12,b,c,d,e,f,a,16 16,2,a,b,c,d,e,f,g,4 0,2,1,i,m,e,k,j,16,17 0,p,1,i,m,e,k,j,16,p 0,2,1,i,m,e,k,j,16,17 Looking at your lis...

@wildmyron: The rule below should fix the top problem (which is especially worrisome). Indeed it does. That helps somewhat, even though it could be worked around by giving turn signals an extra space behind them. I've actually tried both left and right turning loops which is how the discrepancies b...

The loop rule is complete! Making a loop, though, is left as an exercise for the reader. [snip rule definition][/code] Well done - I've been looking forward to you completing the construction done dynamics and seeing what sort of constructions are possible. My simple loop examples I tried during ea...

From looking at your revised rule table, I think it's pretty clear that spaceships are impossible in this rule - because contraction is impossible. Consider the live (state 1 and 2) cells in the northern-most row of the pattern. All the rules resulting in death require at least one cell in the next ...

Can you describe what sort of behaviour this rule is meant to have? I can't see what the idea behind this rule is, but that may be because there seem to be a few problems with your rule table. First off, there's a typo in neighborhood:Moore Second, (for convenience) if you prepend @RULE Pathways @TA...

There is certainly a profusion of rules in the BSFKL family which have tamed the behaviour of the explosive B/S rules they are based on. Thank you Brian for posting golly rule tables and sample patterns for the ones you find. I have a look at most of them to see what they do, and even managed to fin...

This looks like an extension of Byl's loops where you are still using a single sheath but taking advantage of the Moore neighbourhood to allow larger loops without the inner sheath. I think there are some interesting dynamics going on in the interaction between different loops, particularly with mul...

@simsim314: In the first rake I posted, I used a p60 puffer, which should work cleanly: x = 66, y = 66, rule = 22da 55bo$55bo$54bo$52b2o3bo$32bo19b2o$33bo3$62bo2$64b2o$63bo$61b2o$61b2o 11$12bo$13bo7$60bo$61bo7$14bo$13bo2bo$13bo$17b2o$14bo3bo2bo$15bo4bo$ 19bo$17b2o2b2o$18bo3bo$4bo19bo$5b2o13bo$4b2o1...

@simsim314: I really like your LoopParticle rule and I'm looking forward to it's extension if you decide to work on it further. Thank you also for the explanation of how it works - I had noticed that changing the position of the construction head resulted in loops that failed to complete, and now I ...

I was playing around in 22darealDLA with the p96 gun trying to find a small, stable glider turner and stumbled across a very long series of interactions between the glider stream, a glider reflector, and low period oscillator debris. The result is a p189792 oscillator. Now, high period oscillating p...

The former is very inefficent, so the latter would be by far the best ... were it not for the fact that I do not have any GEP -> G converters handy. I don't think it will help you out for the sawtooth, but is this what you mean by GEP -> G: x = 20, y = 31, rule = 22da 2$7.A$6.A2.A$9.3A$2.A4.2A.2A.A...

22darealDLA still hasn't been proven omniperiodic, but there is a stable glider duplicator. x = 41, y = 40, rule = 22darealDLA 40.B7$24.B4$21.B6$27.B2$15.A2$17.A6.B$9.B5.2A$15.2A2.A3$6.B6$12.B4$9. B3$B! Here is a reflector with faster recovery time than duplicator + dot: x = 16, y = 16, rule = 22da...

And here is some interesting pattern but it needs to be "stubilized": x = 4, y = 4, rule = B2SF2K1 .A$3.A$2.2A! x = 6, y = 5, rule = B2SF2K1 4.2A$2.A$A$A$2.A! A variation of the first pattern which isn't explosive, but creates many high period oscillators: x = 12, y = 12, rule = B2SF2K1 8.BA$9.ABA$...

This is an area which I am really interested in too but for the moment I don't have a lot of theory to contribute. My own ideas revolve around combining a diffusion CA with some sort of chemical automata. But for the moment I'll following along with the discussion here. Unfortunately I have yet to f...

A dirty but compact p120 rake: x = 22, y = 50, rule = 22da 2o2$2obo$bobo27$11bo$9bo2b2o$11b2o$5bo3b5o$4bo6bo3b2o$3b2o2bo8b2o$2b2o $6b2o$2b2ob2o$3bobo7bo2b2o$15b2o2bo$14bob2ob2o$18bo$19bobo$19b3o$14bo 5bo$14b2o3bo$13bo7bo$11b2o$11b2o! Probably useless but surprising puffer interaction: x = 71, y = 71...

Is this "back puffer" known: x = 27, y = 18, rule = 22da bo$2o$4bo$5bo$b2o2bob2o$2b2o2bo$o5bo4b2o$bo4b2o$bo3b2o6bo$4b2o9bo$7bo 5bo2bo$8bo7bo$11bobo2b5o$12bo2b2obo2b2o$19bo3b2o$20b2o$22b2ob2o$24bobo ! That seems to be the rake produced by the synthesis above . I don't know how long ago it was found ...

@wildmyron: The problem with that is that it generates puffers as well and might be an unlimited novelty generator. Even if it stabilizes, I would call that an MMS breeder, so unfortunately your solution probably wouldn't work without a few smoking ships or rake convoys. The string idea will also p...

Thanks for posting this. It certainly finds objects a lot more frequently than what I have been using until now. I had to make a few changes to get it to run though: add "import golly as g" indent everything below the while statement add "g.select(rect)" prior to "if len(rect) != 0: g.clear(0)" so t...

@wildmyron: The rake gun is COMPLETE!!! Based on your solution for the duoplet collision problem, I finally made the p960 rake gun. Since there are only four types of breeder, the remaining breeder types are MSM and MMM. snip... I cleaned up the gun a little more and tried to resolve the problem wi...

@wildmyron: That does seem promising. For long glider constructions, it certainly is more useful. (The net number of new p16s that will be introduced in most syntheses involving the glider-emitting puffer is 54.) I tried to solve the duoplet collision problem, but I was deterred by this problem. sn...

How about this style of construction to avoid a long line of glider eaters: x = 773, y = 891, rule = Marked22da 10$140.A.A.A2$143.A$143.2A$144.A4$275.A2$277.A$275.2A98.A$275.2A2.A$ 377.A$375.2A$375.2A2.A24$403.A2$405.A$403.2A$403.2A2.A21$195.A2$195.A $197.2A$195.A2.2A71$391.A2$393.A$391.2A$391.2A2.A...

@wildmyron: In your p150 oscillator, note that a few stages contain a p126 that can be removed: x = 11, y = 10, rule = 22darealDLA B$.2B$2B3.A$.B$2B.A$2.BA.A3.2A$3.B6.A$2.2BA4.2A$3.B$2.B.B! I think it might be possible to use one of simsim314's one-time G->2G converters to make a gun. I spent a bit...

I have been doing a lot in Mites, but I may branch out to a different variant at some point. For the time being I'm trying to make a Mites diode. Did you succeed? I managed a diode for orthogonal mites and I'm sure something similar for diagonal mites is possible too. x = 38, y = 10, rule = Mites $...

@c0b0p0: Thanks for the explanation. I misunderstood what you meant by pulling the duoplets - I thought you meant the reaction which pulls duoplets back into the gun two-by-two. I tried it out and the second rake does indeed destroy the duoplets. ---- RE: odd period oscillators I suspect the odd per...

In 22darealDLA, here is a p10 with only one green cell. Of course I was hoping for it to be anything but another even-period oscillator! x = 8, y = 8, rule = 22darealDLA A.A$2.A4.B$.A.A$2.A.A$2.A2.A$3.2A.2A$5.A$7.A! Are odd period oscillators unusual? It didn't occur to me that they might be rarebe...
