Ugh! Reading further I think that I see where you're headed: a single construction arm that simulates the kind of two glider constructions used by Gemini. That wasn't what I had in mind at all. I was thinking of using the elbow+hand method of construction that the Chapman-Greene arm appears to have been originally designed for. I must confess to being a bit of a n00b at the UCC thing and although I've been privy to a lot of the discussion around these I haven't followed close attention. In fact, I've been guilty of paying practically no attention at all. I was under the (maybe false) impression that slow glider recipes had been found for all of the Spartan still lifes and that this is why they were so special. Then again, I suppose that if that had been achieved, someone wouldn't have been able to resist the opportunity to build a self-constructing UCC before Gemini appeared.

BTW where does the "Standard Synthesis Library" in your synthesis script come from? It doesn't exactly match the Gemini constructions. I ask this, because whilst composing a Gemini recipe for a NE firing SS gun/"slide puffer", I used your script to give me some help at working out a construction sequence for the SE glider injector/reflector. (The NW variant is almost identical to Gemini's x_gun_1 but I had to roll my own for its reflection) At one point the script used a messy looking reaction to create an "fh_ene" and then later used a different reaction involving a pond intermediate to create another one nearby. I specified an "fh_ene" in the YAML file and got the pond-based reaction for both. This is Gemini's default and supposedly quickest reaction. Have you derived quicker ones?

and:
Yes, the SS linear-growth patterns (henceforth 'slide puffers') could be produced collinear to the Gemini, with the line of blocks extending infinitely northwest.
I'm not sure about 'slide puffers'. Puffers are supposed to move. Something involving 'factory' would probably be more appropriate.

As far as the output direction goes, I have already expressed my regrets at the unfortunate direction that I chose. SE or SW also works for an MSS pattern if we place the SS gun/slide puffer/whatever-we-call-it somewhere where it can be activated by a glider fired by the destructor gun of a decendent Gemini. NE is the only direction that introduces difficulties :( .

Never mind. I have been doing some 'out-of-the-box' thinking (this is also a direct reference to my long-winded explanation of Gemini's limitations above) and have realised that there is no reason why a static Gemini's elbows can't travel faster than c/580.

It's the set of reaction used in the Gemini, plus two reactions for constructing loaves, augmented with reflections. The script would be more efficient if you sorted the recipes from the fewest to the most gliders, so that it invariably attempts the simpler reactions first.
Making the movable reflectors would be the hard part
No, Chapman-Greene technology demonstrates that blocks are sufficient. There are slow salvos for translating blocks and radiating gliders, which can then be used in another slow salvo to operate the subordinate block.

You do, however, need to increase the number of gliders emitted by the constructor, exponential in the number of recursive elbows. But since you've only got a chain of two elbows in your MS-Paint diagram, it shouldn't matter too much.

Yes, I abandoned elegance a long time ago.

I wrote (talking about Gemini):
Both X and Y elbows moving SE? They can't both do that.
... to which Keiji replied:
Sure, they can.

If you'll excuse my rough MSpaint sketch:
That's a nice enough diagram but it's not a Geminoid constructor! You've done what I did with Calcymans original slide puffer (made the two constructor arms parallel), and for exactly the same reason. I realise that this can be done, but I was talking about using the original unmodified Gemini constructor. This has perpendicular arms, which leads to the difficulties that I described.

The reason that I that I keep banging on about the Gemini UCC is that it has been built, it works, and it comes with sufficient tools to program it. This isn't really true of any other design. I've already produced a Gemini program that builds the main body of a slide puffer and seen it (the program) in action. I wouldn't know where to start with any other UCC.

Yes, I was thinking of writing in with the same objection. If "a glider in one line would have to be reflected while a glider in another line would have to cause the reflector to translate itself", then the "reflector" starts to look either like a universal constructor (programmed to rebuild itself on command) or some other new technology that hasn't quite been invented yet. Lots of hand-waving required to make it work, in either case.
Keiji wrote:The rightmost one would be even more complicated, as it'd need to be able to move in three directions (NE, SW and SE) rather than just one (SE)
I'm not nearly so worried about that one, actually -- it can be a simple block or some other still-life elbow, and we do already know how to move blocks around any which way, either with synchronized salvos or with slow glider collisions.

The simplest solution along the lines of Keiji's suggestion might be to include a new construction arm with every SS breeder, and have the recipe blow a hole in the previous construction arm to let the next set of signals through to run the next arm in the series. But there are still some technical problems to solve there -- the construction arms have to be lined up in an exact diagonal, or repeaters need to be built to shift the construction signals to a new diagonal... and in either case, a few still lifes have to be built in line with the current construction arm or on the far side of it, which requires constellations of one-time turners, pushing a few still lifes around with slow salvos, or other new tricks. -- The original Gemini does use similar one-time turners to build its construction-arm elbows, though.

This kind of problem will get a lot easier to solve, by the way, once a new Geminoid replicator unit appears based on some of the results from Paul Chapman's latest search utility. It appears to be possible to put together a construction arm that needs just two data channels to drive it, instead of four. The new arm will be a lot smaller, too -- just a couple of stable reflectors, one for each channel, with maybe a short additional chunk of Herschel conduit attached.

But that's all another story for another thread. The other thing I thought of was that the two slide guns in Paul Tooke's sample Spartan block-laying gun could be reduced to one, reducing the total number of driving gliders. I can find a four-glider reaction immediately --

Code: Select all

#C INC5 elbow producing two LOM blocks per 4-glider cycle
x = 88, y = 86, rule = B3/S23
2o$2o4b2o$6bobo$6bo6$15b3o$10b2o3bo$9b2o5bo$11bo8$4b2o$4b2o2b2o$8b2o3$

3bo$59b2o5bo$61bo21$85b3o$85bo$86bo!
I'm sure there are 3-synchronized-glider solutions, and actually I wouldn't be surprised if there were a 2-glider reaction that worked -- maybe by throwing still lifes off alternately to one side and then the other. If this is an acceptable modification, then it should be possible to design a much smaller SS breeder, making the whole construction problem quite a bit simpler.

Keep the cheer,

Nice. It would be even better if Gemini had a clean version of this in its instruction set! I did think to myself that before embarking on ways of implementing an SSS or MSS breeder that I ought to research glide guns and associated reactions before proceeding, but obviously didn't try hard enough. This four glider reaction could work: all four guns would be on the same side of the output channel (this is very important for a Gemini-based MSS breeder, see below) and one of the gliders (the block deleter) doesn't need to be synchronised.

and ...

Actually, the problems I've come across haven't been down to the glider count, but the number of synchronised gliders. Creating the guns to fire the slide gun output was trivial. Adding the activation sequence to insert the gliders into the guns took considerably longer. Essentially, one is looking to recreate the salvo being fired by the guns somewhere behind their input channels before reflecting them in. There is some leeway, but ... well, let's just say that it isn't always easy. Furthermore, I hadn't realised how much that the dispersed boat/blockic turners would slow down the construction of the whole pattern.
So, I've done things the wrong way around. I have a working and tested Gemini constructor recipe which builds and activates a NW-firing SS gun but cannot use it to create an MSS breeder because there isn't room! I didn't realise how little space Gemini leaves unused. Essentially, the only safe space to build anything in is a diagonal stripe just over 200 fd wide between succesive destructor gun output channels or the slightly wider space between the instruction tape channels. Anywhere else is totally unsafe, or impossible because it is outside of the creating Gemini's construction quadrant. A single slide gun would just fit in either of those two spaces.
In terms of the number of gliders involved in the slide gun reaction, the obvious minimal number is one. I would be delighted to find a reaction whereby successive gliders from the same gun strike a cloud of (initially Spartan) junk to throw off, well, pretty much anything other than gliders really, before stabilising to allow the glider stream to repeat the same reaction indefinitely. Unfortunately it appears that reactions of this type usually grow towards the gun rather than away from it.

Well, I thought that I had produced an example of an MSS breeder but now I'm not so sure. The pattern works: it does exactly what I intended it to do, but I have reservations which I'll describe below.

But, first the pattern. It is a Gemini puffer, travelling at (1024,5120)/36,460,658 which creates slide guns. The slide guns fire the 'dirty' INC5 glider salvos posted by Dave Greene. These hit a block, extending a line of block pairs indefinitely. The geometry of Gemini means that two lines of these guns are created, interleaved with a diagonal spacing of 2048 cells between the guns created by the two constructors. The pattern is available in a zip archive which can be dowloaded from here. The archive contains two macrocell format files. mss2-gen27197440.mc shows the pattern shortly before the SE constructor completes the destruction of its parent and then uses a single glider from its destruction arm to activate the slide gun produced by its grandparent. mss2-gen254279680.mc shows the pattern at an arbitrary position after it has produced and activated several more slide guns.

It could be argued that it would have been simpler to use p30 or p46 technology for the slide guns and long period c/2 rakes to construct the guns. The bounding box would certainly be a lot smaller! This is true, but I wanted to try an "Intel" rather than "Radio Shack" approach. Yes, it's possible to solder together transisters, diodes and whatever together to make a circuit that performs a custom calculation, but sometimes it's a lot easier to program a sophisticated microprocessor to do the job. Furthermore, I wanted practice at "programming" Gemini. It's actually quite easy.

My reservation about this pattern is that I don't think that I can in all honesty describe it as an MSS breeder. It is a Mobile (Gemini) pattern that creates a Stationary (slide gun) pattern which in turn produce Stationary objects (the blocks.) But what about all of those slide gun glider salvos? Not only is the block population growing quadratically, the glider population is also growing at the same rate. Looking back through this topic none of the "SS guns" that have been posted are anything of the sort. I fact in the first two, Calcymans p92 based gun and my variation of it, the glider population outnumbers that of the blocks at all times and is growing it the same rate. These are all guns which produce both moving and stationary objects at a linear rate. The breeder inherits this so that it is actually a hybrid MSM/MSS. I can think of at least one way to eliminate this objection, but I need to dive back into my collection of gencols results to see if the reaction I'm thinking of is possible.

If you're thinking of having a return glider propagate back towards the source, as in Dave Greene's block pusher, then no. The resulting pattern would grow at O(t^1.5), not O(t^2). Be very careful about calling that a 'breeder'.


But what about all of those slide gun glider salvos?
The periodically spaced glider salvos constitute a high-period wick, therefore stationary.

You seem to me to be stretching the definition of a wick way past it's breaking point. I don't think that a set of glider streams matches most folks idea of a wick.

That is exactly what I intend and I will call it a breeder. Patterns have been called breeders because they breed: they produce offspring that in turn produce offspring. It is this pattern of growth that gives them their name, not the rate of growth. This is why spacefillers are not usually considered breeders, even though they grow quadratically. I am sure that if/when a breeder is produced that grows at less than a quadratic rate, most folks would recognize it as a breeder and call it one. BTW, wasn't it you who corrected me on my assumption that a breeder had to exhibit quadratic growth? :)

So you would consider the replicator puffer in HighLife to be a breeder, even though it grows at O(t^(ln(3)/ln(2)))?

MAJOR EDIT: The original version of this post was based on the assumption that the comments in the two replicator puffer patterns in David Bell's HighLife collection (both of which describe the pattern as a breeder) were written by their respective discoverers. Having done some more careful research, I now believe that both of these descriptions were written by David Bell. Dean Hickerson only described his pattern as a replicator puffer. All that I can say is that when David Bell described the replicator puffer as a breeder in his HighLife article, which went through several review cycles before publication, no-one rushed forwards to contradict him.

This is an interesting example because it doesn't fit the usual breeder growth pattern of: A creates B which creates C. It's more like A creates B which creates B ... and so on. Would I call this a breeder? I have to say that I'm not sure. But if I had any objection it would be based on the different growth pattern, not the growth rate.

Think of the replicator at the front of the line as being a puffer. Just because it's debris behaves weirdly doesn't mean that the whole pattern isn't a breeder.

Why hasn't a glider exploded yet?

As a possible solution to the Gemini UCC-based SSS breeder, try making an SS breeder that produces its string of blocks to the NE. The UCC is in the SW. Its Y-axis elbow moves upwards at twice (or more) the rate that the X elbow moves rightwards, but neither has to move faster than the rate at which the SS breeders produce their blockstreams, because none of the block streams ever cross the construction arms. However, the upward glider salvos from the X elbow may have to pass through the block streams of all breeders produced so far. The best way to manage this is to make sure the blocks wind up in perfect vertical columns. If the horizontal separation between the blocks is enough (say the same distance as the width of the SS breeders themselves), then the salvos can pass between them and build the next SS breeder without obstruction (obviously I'm glazing over a lot of careful timing considerations that would make this difficult, but it does have the advantage of not needing to re-engineer the UCC itself, like the double-elbow arm idea does).

In that case, I would say the highlife replicator is more like a puffer than a breeder. Or rather, two puffers moving in opposite directions. The debris "behave weirdly" in that they never become periodic, but they also don't produce a third kind of object. By thinking of the replicator at the edge as being a puffer, the replicator fits nicely in the same tier as true puffers. However, it is neither MM nor MS. It is M-Something, though.

The archive contains two macrocell format files. mss2-gen27197440.mc shows the pattern shortly before the SE constructor completes the destruction of its parent and then uses a single glider from its destruction arm to activate the slide gun produced by its grandparent. mss2-gen254279680.mc shows the pattern at an arbitrary position after it has produced and activated several more slide guns.

First question ever. Often referred to as The Question. When this question is asked in right place in right time, no one can lie. No one can abstain. But when The Question is asked, silence will fall. Silence must fall. The Question is: Doctor Who?

It doesn't work for me now either, it seems that Microsoft have helped me out again. Try this link and download "mss-breeder.zip".
