Finally trying out stable Herschel tracks...

Postby Awesomeness » July 9th, 2009, 11:10 am

I've been playing around with Life for a while, and I've made lots of interesting patterns, but I've never gotten into Herschel tracks. I've decided to try because of the computation and complicated things you can create with them. After lots of searching for non-".lif" resources for Herschel tracks, (Golly cant open ".lif" file extensions.) I've played around and made a few things.

Here's my first try:

x = 318, y = 226, rule = B3/S23

Its just 2 different loops and 3 experimental conduits. (At least I think they're called that) The eaters with dots near them are not part of the conduit, just to make sure gliders don't get away.

I still don't quite understand how people make stuff like glider-to-LWSS converters and patterns that do cool things with this.

(Golly cant open ".lif" file extensions.)


Depending on the version, Golly may be able to open it. There's a program that comes with xlife called lifeconv (or something like that) that can convert many older .lif files into Life 1.05 format, which looks like this:

#Life 1.05
#D Acorn
#D The most vigorously growing 7-cell
#D "methuselah" pattern.  See also RABBITS.
#N
#P -3 -1
.*
...*
**..***

Golly can easily cope with that sort of file, although it'll ignore the (-3, -1) pattern origin info. Some .lif files use a slightly different system, but can be fixed by hand, or a simple script. I managed to convert most of the Life32 pattern collection. Some .lif files are more complex, and define patterns in terms of sub-components, some of which may be defined in other files. The conversion program doesn't work properly on these. :(

What you have there is a Herschel-to-R converter that releases a glider. You could try manipulating the R-pentomino in some known way to whatever effect.

It might be possible to get a Herschel-to-glider or Herschel-to-junk converter out of this, by adding more catalysts in the twenty-odd ticks between the time when the R-pentomino was created and when the R's products destroy the eater. But I'm not too optimistic: there are very few places to put new catalysts where the active pattern wouldn't already have destroyed them.

Sokwe wrote:What you have there is a Herschel-to-R converter that releases a glider. You could try manipulating the R-pentomino in some known way to whatever effect.

The biggest problem is that the R-pentomino shows up in the wrong orientation, travelling back toward the block, so none of the known conversions are going to work -- you'd have to magically shoehorn something in there _after_ the block has done its initial catalyzing job.

The eater catalyst is in a known position, and it turns out to be possible to substitute a regular fishhook eater for the eater2. Here's a comparison with one of the variants of the Fx77 conduit -- run this step by step to see where the differences show up in the reaction:
x = 32, y = 70, rule = B3/S23
20bo$20b3o$23bo$22b2o2$3bo$3b3o$6bo$5b2o11b2o11bo$18b2o9b3o$29bo$29bo

4bobo$4b3o$6bo5$16b2o$16b2o!

So the block catalyst is in a slightly different location, but that's partly because in the Fx77 there's an additional "transparent block" catalyst that modifies the reaction very significantly, before the block does its work.

I'm going to add a new topic describing the tools that are available for working on this kind of problem. As folks have mentioned elsewhere, it's a little odd that only one new Herschel conduit has been discovered this century, after the Cambrian explosion of new inventions in the mid-nineties.

Apparently people stopped spending the necessary search time, because the known conduits got to be enough to make a "universal" toolkit that can build pretty much anything (given enough space and time)... as Brice Due's eaters-only F171 shows, it's not as if there are no more conduits waiting to be discovered! Quite likely there are dozens more stable conduits out there, and hundreds of periodic ones.

I tried it out and ended up with a partial H-to-G that creates an extra block.

Image

Using a different approach I found a partial H-to-G that deletes a block.
Both are shown here:

x = 77, y = 16, rule = B3/S23
2o$2o$64b2o$64b2o$21b2o$21bobo$23bo$23b2o4$6b3o7b2o45b3o$7bo8bobo45bo
8b2o$7b3o8bo45b3o6bo$18b2o54b3o$76bo!


Since they complement each other I combined them like this, using F171 to delete the block:

x = 162, y = 65, rule = B3/S23
26b2o$27bo8b3o$27bobo8bo$28b2o7b3o$20bo$14b2o4b3o$15bo7bo$15bobo4b2o$

The F171 is rotated 90 degrees clockwise in the pattern on the right.
It just happens that the two converters don't interfere with each other's still life in either case.
Of course, the limitation is that the block must be formed before it can be deleted, as shown.
The F171 conduit was added just as an example, to allow time for the block to be created.

There is a very simple stable H-to-G converter, however, that is commonly used:

I've just found one with 30 seconds of tinkering which deletes a block. Another almost-H-to-G converter.

Another almost-H-to-G converter.



However, there is not much point stabilising these partial H-to-G devices, since they do not achieve a different path or timing to the beehive termination.

If you manage to emit a glider on a different path (to the 25 or so already discovered), it might prove very useful in completing stable reflectors.

Once upon a time I wrote up some notes on how to semi-automatically convert these Xlife #I-format files into Golly scripts.

Unfortunately it's not altogether easy, and for the small volume of #I-format files that seem to be in existence, writing a converter utility wasn't quite worth the effort. Golly scripts definitely seem to be the way to do this kind of structured pattern representation nowadays.

You need a good imagination, a very good memory for patterns you have seen before and where to find them, and last but not least, perseverance. What you have is a construction kit that allows you to engineer new ideas from existing pieces. Even if you have a very good idea that is superficially plausible, you will run into snags where the details don't let you build what you intended. But with perseverance you can finish the construction. Herschel tracks let you create glider salvos that can then synthesize spaceships and objects, so I would say glider synthesis is a must for constructing "cool things". Typically the patterns that are interesting have a repeating theme (oscillators and loops) and make use of converters (like H-to-G and G-to-H converters) or grow infinitely (guns) but not necessarily: that is where the good imagination comes in.

I can only guess how many snags there were and how much perseverance it took to overcome them when constructing the giant caterpillar spaceship. I think its size indicates the large number of snags encountered, with each solution requiring more pi crawlers and increasing complexity.

This has been an attempt to answer your question. Not sure it has.

This question has a couple of possible interpretations:

1) How do people go about discovering new conduits -- i.e., conduits that make use of reactions that were not previously known, such as a new stable conduit that converts a glider, or maybe a Herschel, directly into an LWSS?

2) How do people go about stringing together known conduits to do new things -- e.g., accept a glider input, produce an output LWSS, and fix everything up to be ready for another glider input?

#1 is something I've been sort of planning to write about sometime -- some kind of "best practices" document for the 'ptbsearch' and 'catalyst' utilities would be good to have, among other things -- but it's probably going to take a while to get a good summary together. It's really easy to spend a lot of time trying to fix the unfixable, following likely dead ends that other people have already tried -- but there are also huge areas of stable-conduit search space, easily within reach of today's computers and search programs, that haven't even been looked at yet.

I tried to address #2 in a separate topic last month -- that was a first swipe at an introductory explanation of Hersrch, the most powerful search tool currently available to help put together synchronized Herschel circuitry. Let me know where this needs more (or better) explanation, and I'll see what I can do...

Known stable Herschel technology is versatile enough to construct any pattern that can be produced by colliding gliders. That is, if you have a glider recipe to construct a given object, then with Hersrch's help you could build a contraption that takes (say) an input glider as a trigger, produces that object as output, and returns to its original state afterwards, ready to produce another object at the same location... or if the object is stationary, at the next location along a line, or whatever.

The circuitry may take a lot of time to recover, and use up a lot of space, but it can always be done somehow. If anyone thinks they have a counterexample, I'll be happy to try to shoot it down...!

What if the pattern can only be constructed by using tightly packed salvos that are not themselves constructible? Has it been proven that any glider salvo is constructible? I suppose there is usually a different way to get the same result.

I would like to see a herschel track lay down tracks in front of itself so it can continue to lay down more new tracks indefinitely. It would be extremely slow but I think that one could be done.

That's what I'm counting on, in making my overconfident conjecture that Herschel Conduits Can Do Anything... certainly it's easy enough to produce gliders following each other at the minimum possible spacing -- just use a variant of the reactions in the pseudo-p14 gun, for example.

But no, I haven't formally proved by induction that for any patch of N gliders, it's always possible to find at least one that can be added to the rest of the patch using Herschel conduits. Might not be hard to do, though -- the best trick might be to find a small constellation that can be constructed way out in front of an oncoming fleet, that can be hit by a glider or *WSS from the side at the last moment to produce an edge-of-envelope output glider to add to the front of the fleet.

Let's see, a couple of the turners in Golly's Syntheses/blockish-and-blockic-seeds.rle work fine at p15:
x = 37, y = 23, rule = B3/S23
21b2ob2o$21b2ob2o$16b2o$16b2o5$34b3o$34bo$35bo10$2o$b2o$o!

For that matter, a simple kickback reaction could produce the same spacing. So that just leaves p14, and maybe a few slightly worrisome cases with gliders right next to each other -- I bet something can be found to handle each possible case. In which case I wouldn't even have to use the different-way-to-get-the-same-result defense (though I bet that's also valid!)

knightlife wrote:I would like to see a herschel track lay down tracks in front of itself so it can continue to lay down more new tracks indefinitely. It would be extremely slow but I think that one could be done.


Couldn't be slower than a Herschel moving through the circuit, could it? Or are you thinking of using multiple Herschels somehow?

You need at least a couple of still-lifes per conduit to get a glider out of a Herschel, and at least a couple of gliders per still-life to build more conduits at the front. So I don't immediately see how you'd generate enough gliders to keep the thing going, no matter how many parallel tracks you had. And among other problems, it's also surprisingly difficult to get a forward glider out of a constructible Herschel circuit. Otherwise we might have a Caterpillar spaceship by this time that uses Herschel tracks, instead of pi heptominoes climbing on blinker trails.

The other good thing about blinker trails was that they could be moved to let glider streams pass through them -- Herschel conduits are much less forgiving, though they are permeable here and there...

If the Herschel has to keep going straight, I thought, then that is true. Parallel Herschel circuits would just make things worse. Then I thought a track could be built out in front using parallel circuits if there was enough time before needing to use it. Of course the new track needs the parallel circuits built also so that the sequence can be repeated. The delay, I thought, could be a glider that goes to a distant 180 degree reflector and back before converting back to a Herschel and continuing on its track. In other words, build a specialized replicator triggered by a spaceship that builds another one in front of itself, finally triggering the new one with the same type of spaceship. This is cheating because the tracks would be discontinuous but it would certainly be a new kind of puffer! There is the problem of building the reflector for the delay, but maybe if it were placed behind rather than to the side then the same one could be used over and over. The delay would keep getting longer and longer as new tracks are laid in front.

You are right that there aren't enough gliders. A Herschel track does not make enough gliders to build itself. That is where this breaks down. Another source of gliders would be needed such as Herscel loops, guns or rakes launched to the side. Block laying puffers could create corridors of blocks on either side of the track that consist of those cool one-time glider replicators made of blocks. I know, this is getting far fetched.

All this makes me wonder if a Herschel can merge into an existing Herschel loop for delay purposes.

Once you allow extra rakes and such off to the side, you're kind of back in known territory, though. Have you seen Puffers/p100-H-track-puffer.rle in Golly's pattern collection? There was also another rake-based track-builder breeder pattern where Herschels were continuously created at the front of the track, and travelled to the back. Could dig that up if you're interested and can't locate it.

knightlife wrote:All this makes me wonder if a Herschel can merge into an existing Herschel loop for delay purposes.

Technically, no, not in while the signal is in Herschel form anyway: the catalysts that keep a Herschel from misbehaving when it's coming in from one direction are never far enough apart to allow another Herschel to come in from another direction and wind up in the same place. Not in currently known conduits, anyway.

But there are lots of workarounds... most of which involve gliders. Two parallel gliders separated by 2, 5 or 6 cells can be caught by a Herschel receiver and turned into a Herschel, quickly and easily as these things go. A receiver can also catch just about any pair of gliders on crossing paths, often in several different ways.

So suppose that a set of these "tandem gliders" is produced by edge-shooting H-to-G circuits or permeable conduits -- e.g., the Fx77 and F166 let a glider pass through on the same path as their standard output glider, and several others can be made to work as well. Another set of tandem gliders farther upstream can be created with standard Herschel conduits... and there's your merge circuit.

But if repeat time isn't an issue, the simplest trick is to convert the Herschel signal to a glider, and merge glider streams instead and convert back to a Herschel later. For example, here's a startable/stoppable p1024 Herschel loop that I put together for Calcyman a year ago, when he was working on his stable non-totalistic unit-cell metapixel project (!)

#C P1024 Herschel loop gun w/ glider merge input and boat-bit stopper
#C Send another glider in at the bottom to cleanly shut down the loop
x = 118, y = 114, rule = B3/S23

A little farther out on the lunatic fringe, here's a merge circuit using two synchronized gliders that sneak right into a standard block-snake catalyst in a Herschel conduit, and add another Herschel on the fly:

Nice. The use of the rectifier to clean up reminds me...
I found the rectifier can clean up the pesky block that a B-heptomino creates before becoming a Herschel:

The stable B-to-H from the life lexicon is shown for reference. The Herschels are mirror images of each other.

If the rectifier is in the way it can be moved further away in the SE diagonal directiion (or closer in the NW diagonal direction if possible), afecting recovery time.

Re: Finally trying out stable Herschel tracks...

I've been playing around with ptbsearch and have found a few things of interest. First, a periodic R135 Herschel conduit (shown here at periods 4, 5, 6, and 8):

It is of particular interest because it uses a well known still life that is part of many low period oscillators but was not used to catalyze larger reactions until a search by MikeP found it. I have had some success in using this still life with ptbsearch. The only use for the new conduit that I could see at the moment is a slight improvement of the p316 gun (using modified p4 sparkers to reduce size further):

I have also recently been looking at stable circuitry that converts one common pattern to another. As far as I could tell, there were no known century-to-Herschel converters, so here are two (I would not be surprised if these are already known):
x = 72, y = 28, rule = B3/S23
63b2o$63b2o2$54b2obo$54bob2o$2o$bo28b2o38b2o$bobo26b2o38b2o$2b2o42b2o$

9b2o$50b2o$51bo$48b3o$48bo!

The only patterns I can think of where the century features prominently are the p246 gun, bistable switch, and Diuresis. The only one of these patterns in which a century-to-Herschel converter would be applicable would be the bistable switch, but the above converters do not work with it.

With a little bit of searching I came up with this (very slow) pi-to-century converter (this also uses MikeP's still life catalyst):
x = 33, y = 38, rule = B3/S23
32bo$30b3o$15bo13bo$15b3o11b2o$18bo$17b2o14$6b2o$2b2obobo$o2bobo$2o2b
2o3$5b2o$5b2o6$13b3o$13bobo$5b2o6bobo$4bobo$4bo$3b2o!

This works with one of the century-to-Herschel converters above, and, when combined with the known Herschel-to-pi converter, gives a new conduit, Lx496:
x = 60, y = 61, rule = B3/S23

It's so slow and bulky that it probably will not improve any guns, unfortunately.

Also, one of Guam's new conduits can reduce the size of the p421 (and related p842) gun:
x = 101, y = 76, rule = B3/S23

There are likely other gun improvements from these new conduits, but I have not tried much.

Request: Does anyone have a thorough collection of the known stable converters. I am especially interested in circuits that convert common objects to other common objects, as well as converters of common objects to gliders (or gliders to common objects). Below is a collection of all of the somewhat interesting converters that I can find (excluding Herschel-to-X, glider-to-X, and X-to-glider converters). Is it missing anything?

A side note: Guam's new Herschel receiver (posted here) needs two parallel gliders with a path separation of 4, which fits nicely between the possible separations for Callahan's receiver (2, 5, and 6).

Re: Finally trying out stable Herschel tracks...

Impressive work! I may even squeeze a LifeNews article out of these discoveries.

Is it missing anything?


Yes, there's a R-to-H converter from the paleo-Herschel era:

x = 22, y = 20, rule = LifeHistory

This, as well as the new stable HWSS Heisenburp (please include that in the article), has re-fired my interest in stable circuitry. However, I'm thinking of using two non-standard reactants: an R-Mango (how common is that, again?), and also an Octomino methuselah (the one that can be synthesized with two gliders).

EDIT: Some promising octomino reactions:
x = 106, y = 29, rule = LifeHistory

This looks to be the best candidate for a reaction:
