Re: Half-bakery reaction with glider

I've made some progress towards writing a weighted search script for the knightship. I believe, the only thing that is left (besides fixing some probably yet hiding bugs) is to set up output for recipes in a machine-readable format, that I'll hopefully finish in the next days.

The script looks for transmutations between blinker, block, tub, boat, hive, ship, loaf, long boat, pond, traffic light and honey farm, optionally emitting an orthogonal glider.

A sample result for a teaser:

Code: Select all

x = 483, y = 503, rule = B3/S23

I've tried different scenarios, but now I'm out of ideas. 12 gliders is worse than 10, but still okay. Cleaning up two last gliders with one 'guard' per glider is of course trivial...
I've looked also, and haven't found any good ways around the obvious geometry problem: for the standard pair of rake gliders, a single guard glider can't reach the lead glider's useful sparks -- the second glider's half-bakeries are in the way. Attacking from the other (NW) side just tends to destroy the half-bakery, which is not what we want.

So I've given up and gone back to Rake #1. As vaguely promised in a previous message, here's a fairly random way to suppress a total salvo of 11 synchronized gliders. No doubt this can be tightened up considerably. But the length of this absorber unit will be a tiny fraction of 1% of the full knightship length, so it's probably not worth doing anything with it -- unless someone can figure out how to reduce the synchronized salvo to 9 or 10 gliders, of course.

The two guard gliders are labeled "G". Super mega bonus points for anyone who figures out how to do without one or both of these. The spacing between A, B, C, and D subunits, and within the A subunit, can be adjusted arbitrarily if the input gliders are adjusted to match. The D gliders are timed to allow the southwest cleanup reactions to work. Other timings would most likely also work, but with completely different cleanup reactions -- there are a lot of options available.

The script looks for transmutations between blinker, block, tub, boat, hive, ship, loaf, long boat, pond, traffic light and honey farm, optionally emitting an orthogonal glider.

A sample result for a teaser...
Looks very good! That seems like a good place to draw the line, between longboat and toad -- especially since ships are probably a lot more common in this context than random-soup statistics would indicate, because of their presence in B-heptomino ash. I can't think of any really common constellations besides traffic light and honeyfarm that really need to be considered as separate targets; half-blockades will show up a lot in the middle of recipes, but they can just as well get mutated one more step into traffic lights, blinkers or honeyfarms.

Anyway, it might be time now to start working on building actual synchronized-glider-salvo seeds...!

This is actually pretty easy to do using invariants. You don't necessarily need to build synchronised salvo purely by seeds, you can intermix half-bakeries to adjust relative glider positions between seeds. That's why your estimate of 50 still-lifes is probably exaggerated. Adding 3 still-lifes makes two synchronised gliders out of one. That means given two initial gliders sent to either chain of half-bakeries, you'll need roughly (3-1)*3+(8-1)*3 = 27 still-lifes.

EDIT: I added guard gliders, but I had to change one of them to find a suitable reaction.

EDIT: It seems, that guard glider pairs in both your and my patterns are not good, because it would be much more convenient, if they allowed HB-transformations on them, to be adjusted in parallel with the main construction salvos :(

Yes, I just ran into that same annoying little problem. Easy to solve -- the trailing guard glider just needs to be six cells or more to the right of the leading guard glider. But I don't know what the relative spacings are for the splitters you've collected.

Can you do anything with the following pattern, for example? The two yellow gliders need to be generated by a one-time splitter reaction. Sorry to mess up your previous good work, but this is actually the closest allowable spacing for the D trails -- I had left extra space in the previous sample pattern.

Your Herschel-based glider splitter does a good job of reaching across the extra distance between the C and D trails, but it leaves junk spread over a relatively wide area. It's certainly usable, but maybe a tighter trail spacing would allow it to be replaced by a smaller splitter...?

The two green guard gliders are HB-compatible but lots of other relative spacings could be used instead.

EDIT: Added a second pair of yellow gliders on the A side, and put more distance between seeds again to allow for more efficient construction (using several slow elbows in a near-diagonal line, instead of just one elbow).

Thinking through the SW suppression again: it might be a good idea to build a test pattern that runs through several full rake scans, just to make sure there are no unpleasant surprises there. The shooting-range width shown above is a good bit too narrow to support a reset. I'm pretty sure it will just be a matter of adding several consecutive resets (without firing any gliders) to the NE end of of the trails -- but it's worth double-checking.

To support the above set of suppression reactions, the A and BCD trails have to be this exact distance apart... This suggests that a shorter HBK back end might be found by allowing the NW and SE trails to approach each other more closely before they start shooting suppressing gliders back and forth at each other.

Re: Half-bakery reaction with glider

Post by codeholic » June 26th, 2014, 3:37 pm

I wonder, if it's possible to use only one guard glider by using the following reactions on the most SE glider of the A-track, after cleaning up all other gliders but this one and two gliders of the D-track.

Re: Half-bakery reaction with glider

Post by dvgrn » June 26th, 2014, 10:48 pm

codeholic wrote:I wonder, if it's possible to use only one guard glider by using the following reactions on the most SE glider of the A-track, after cleaning up all other gliders but this one and two gliders of the D-track.
At first glance, it looks as if it might possibly work, just by sheer luck... I think the D-track timing will have to be adjusted to allow some subset of A, B, and C to be shot down. Then it's just the luck of the draw whether the remaining A glider can be guarded to produce a 90-degree glider that can stop the D track.

It's worth trying, especially since different spacings between A and BCD will produce different collision timings for 90-degree gliders crossing the shooting range. It will probably take several days for me to sort through all the possibilities (or even some of them).

Here's another idea that came up today: what if a suppressing collision leaves behind some junk, but that junk can be harmlessly cleaned up by the _next_ iteration of the HBK -- i.e., the same junk-producing reaction happening at (-3,-6)?

Code: Select all

x = 24, y = 16, rule = LifeHistory
21.A.A$A20.2A$.2A19.A$2A$11.A.A$11.2A$12.A2$9.2D$9.2D5$12.2A$12.2A!
This one would double the period of the whole construction, but it would actually work okay otherwise... Or if the collision is compact enough, possibly a whole line of blocks or blinkers with (-3,-6) spacing might be produced, which would eventually get in the way of the next glider to the southeast.

Seems like there's some potential for generating blocks or half-blockades even on the A side, and letting the line of junk drift across the shooting range to clean up junk on the BCD side. I'll have to look at this more carefully and see why it won't actually work --!

EDIT: That last idea doesn't work the way I thought of it. Junk produced by gliders from the SE (a rake on the BCD side) and NE (the A gliders) will generally get in the way of the next (-3,-6) offset glider pair. But it might still work with gliders from the NW and NE, similar to the example above.

Oh. Now it looks really trivial.

Re: Half-bakery reaction with glider

Post by chris_c » June 28th, 2014, 8:03 am

Hello,

I've been working on this fun problem for a while. Here is my basic design. It uses only eight gliders. The eight 90 degree reflectors that are involved are reset at offset (-3, -6) using another 5 * 8 + 3 * 10 = 70 gliders.

Code: Select all

x = 746, y = 883, rule = B3/S23

My hope is to avoid any seeds that fire more than one glider. Once the reflectors have been reset it should be possible that eight gliders from the main SW/NE channel can be used to restart the reaction. Correct timing can hopefully be achieved by altering the spacing between the reflectors. E.g. moving a reflector one square to the north east will delay the returning SW glider by 8 generations. Putting an extra half-bakery in the way of a SW glider delays the glider by an odd number of cycles, so hopefully any timing is achievable.

Next I have four monochromatic salvos that reset both of the refelectors and give SW gliders of either colour. They are reasonably optimised for the number of "passes" required but could definitely be improved. More on this later.

Finally I have a very silly monochromatic salvo that shifts a honey farm by (-3, -6) and produces an extra loaf that can be pulled arbitrarily far away from the honey farm. Also as shown, it is easy to transform this loaf back into a honey farm of either color to act as a seed for any of the above 4 salvos. This pattern is very inefficient and was made almost entirely by hand. It would of course be better to be able to reconstitute the honey farm seeds directly from the ash of the big monochromatic salvos but it seemed daunting to do that once never mind four times over.

Here is a bit of explanation of how I came up with these salvos.

First of all I hacked gencols with the following little patch so that gencols only considers "even" translations in both the printing and the generation stages.

Code: Select all

     while (*tcell) {

 	delgen(tmp,ALLGENS);
 
         /* set up collision */
It seems to work as expected but I do not understand the gencols code well enough to be 100% sure.

Next I used this very crude script to filter for patterns that only produce gliders in a single direction (either NW or SE). It is based on a script that dvgrn wrote elsewhere on this forum. I can't remember where exactly.

Code: Select all

  all = f.readlines()
  f.close()
  f = open(OUTfilename, 'w')

From here I noted on which lane the glider was shot for each turner and how many passes were required to build the reflector (both in the shown orientation and the reflected one). Also, for the ash of each turner I found by hand a list of locations where a new honey farm could be created. The number of passes in the regeneration stage is unoptimised.

That data resulted in the following silly script.

Code: Select all

# Data format:
#
# 0. color of hf
# 1. glider shoot distance
# 2. rough cost for right shot
# 3. rough cost for left shot
# 4. distances new hf's can be generated at. 1 in the second element of the
#    tuple indicates transformation is via a block and so up to MAX block
#    pulls are permitted before making the new hf.
#
# All data was generated by hand so could easily contain mistakes.

dat = [ (1, +11, 2, 2, [(+13,1),(+9,0),(18,1),(23,1)]),  #2 loaf, 3 ship,
        (0, -11, 3, 2, [(+7,1),(-12,0),(-17,1),(-3,1),(3,1)]),
        (0,  +3, 3, 1, [(-7,1),(-31,1),(-19,1),(-17,1)]),

            a[j], a[j+1] = a[j+1], a[j]
With more careful optimisation and perhaps a collection of turners that can be made from objects other that a honey farm (hive would definitely be the next most useful starting object) I'm sure these salvos could be improved a lot. Nevertheless I think it should be possible to build a complete spaceship based on these components.

Re: Half-bakery reaction with glider

What! I was just working on cutting down codeholic's ten gliders to the "minimum" of nine, and along comes this pattern with a perfectly good HBK-buildable three-glider collision. Serves me right for not spending more time with gencols to double-check my custom search program; I had, um, proved some weeks ago that there were no workable three-glider recipes for NE gliders. Looks like I probably discounted some very close spacings for the trailing glider, thinking they would crash into the half-bakery reaction.

Anyway, congratulations! This should cut the knightship down to under a million cells on a side, probably a good bit less -- and it's buildable pretty much any time we decide to stop optimizing. There may be some discussion coming up about the relative efficiency of multi-glider seeds...

I have some ideas for getting down to the new minimum of seven synchronized gliders. Now that we don't have the extra degree of freedom from the D gliders, it will just be the luck of the draw whether it works or not, but maybe it's worth having a look anyway.

EDIT: The first of your monochromatic-salvo patterns seems to be a copy of the previous sample pattern. The other three all look good.

I don't think this particular reaction can quite be made to work -- there may not quite be enough room to suppress the B gliders using a single C output, even if the timing happens to work out. I cheated in this pattern -- the yellow blocks are just there to allow the rest of the trick to work.

However, there are a number of other possible objects that can be built at A, that will eventually make a line down to intersect with B and C. Possibly another small object will turn out to be able to absorb a couple more gliders...?

Re: Half-bakery reaction with glider

Post by codeholic » June 28th, 2014, 5:00 pm

I'm looking for a good way to record slow salvo elbow operations. Please give me feedback if I'm missing something or you think there's a better way to record them.

There is a list of targets. Still-lifes without rotational period of order 4 are have numbers in their names, e. g. "hive1", "hive2". If the target is p2 (i. e. a blinker or a traffic light), then one phase is chosen as "standard" and the difference in phases should be denoted separately.

In order to get canonical recipe, you put the target in the center, so that top left corner of its bounding box is either at (0, 0) or at (1, 0). Since construction is monochromatic, it makes a difference.

Then you send gliders on half-diagonals even numbers. The glider lane is defined as the x-coordinate of leftmost diagonal of a glider's track, where it crosses the line y=0.

Glider parity is 0, if it's in the canonical phase, otherwise 1.

Code: Select all

x = 66, y = 27, rule = LifeHistory

59.D$58.D$57.2A$58.2A$57.A!
The record for the left recipe is

Code: Select all

blinker:0 -6:0 traffic_light:-5:-5:1
It means: Start with blinker at (0, 0). Shoot a glider at phase 0 on the lane -6. The result is a traffic light at (-5, -5) in the phase 1.

The right one

Code: Select all

blinker:1 6:1 traffic_light:-2:-2:0
Start with blinker at (1, 0). Shoot a glider at phase 1 on the lane 6. The result is a traffic light at (-2, -2) in the phase 0.

Any suggestions on how to record emitted gliders?

Normally I would name generation #, place and direction of the glider ... plus the phase it was first found it in. (or gen# and location are adjusted such the first appearing is allways with "phase 0").

In your current context, using lane numbers, color, phase and generaration offset relative to your target instead might be more usefull.

Your notation seams to only work if you hit ONE target with ONE glider at a time and get ONE result.
(Plus you do not spell out the direction of this glider - but if I get it right, this is fixed anyway).

If you disregard anything beyond "simple target" + "single glider" -> ["simple target" and/or "single emitted glider"]
your notation should work.

You are probably not interrested in 180° reflected gliders or ones travelling in the same direction as your bullet.

So: adding something like

Code: Select all

left:same:-3:1
to your notation might suffice.
(i.e.: emitted glider is turned 90° left from the original one, same color, lane offset -3, phase difference 1)

If you need the exact timing you could add a generation number like in

Code: Select all

left:same:-3:1:#30
This number should probably not be the generation you detected this glider in, but rather the generation in which it (virtually) were at collision site (or, in this case, 3 spaces below the top left corner of your original blinker).

That's a very cool idea! It turns out that widening the shooting range allows time for an extra trick before the C salvo dies:

Re: Half-bakery reaction with glider

Post by codeholic » June 29th, 2014, 3:13 am

chris_c wrote:My hope is to avoid any seeds that fire more than one glider. Once the reflectors have been reset it should be possible that eight gliders from the main SW/NE channel can be used to restart the reaction. Correct timing can hopefully be achieved by altering the spacing between the reflectors. E.g. moving a reflector one square to the north east will delay the returning SW glider by 8 generations. Putting an extra half-bakery in the way of a SW glider delays the glider by an odd number of cycles, so hopefully any timing is achievable.
I'm looking forward to see, whether it will really work. A good thing is that additional reflectors can be built directly by the main construction salvo.

I think it should work. Here is a stripped down version that shows the A salvo regenerating itself. I don't see why the same thing wouldn't work with more complicated reflectors than boats. If more space is required between reflectors it is always possible to add extra delay to the next NE glider by making a gap in the main body of HB's.

I think it should work. Here is a stripped down version that shows the A salvo regenerating itself. I don't see why the same thing wouldn't work with more complicated reflectors than boats.
Sure looks good to me! So maybe a good next step would be to find slow elbow recipes with as few resets as possible. As a wild guess, I bet there are monochromatic recipes that go from junk(0,0) to junk(-3,-6) plus a 90-degree glider, with just four or five resets.

Seems as if it might work well to have seven separate slow elbows, each assigned to a different set of lanes in the shooting range, and each with its own ¨superslow elbow¨ paired with it. That way the seven superslow-elbow and slow-elbow rebuilding recipes can all be happening in parallel, one glider for each recipe for each scan across the shooting range. So... how narrow is the narrowest universal monochromatic set of slow salvos?

Not sure how useful this is, but it does create a half-bakery, two blocks, and two orthogonal gliders:

Code: Select all

x = 10, y = 23, rule = B3/S23

It is probably possible to avoid slow elbow construction for the SE salvo by building edge-shooting 180-degree reflectors with the main NE construction salvo directly and then move gliders down to the right positions by half-bakeries.

Sample same-color edge-shooting 180-degree reflector:

Code: Select all

x = 294, y = 302, rule = B3/S23

If it appears, that there is one degree of freedom too few for a 180-degree reflector, one could still apply the same technique by building two 90-degree reflectors with the latter being edge-shooting.

The next idea for improvement, that follows from it, is to use 4 SE HB-rakes and a NW HB-reflector, rather than 2 SE and 1 NW HB-rakes, that would allow to reduce amount of HB-trails, re-ignited with a slow elbow, to one. However, in this case a problem with resets may arise, so it might be necessary to set a long chain of half-bakeries to separate the first SE rake from the other three to make space for resets. So it's not quite clear, whether it would reduce the bounding box.

Excellent idea. The SE side could be really cheap to make if this works out.
codeholic wrote:The next idea for improvement, that follows from it, is to use 4 SE HB-rakes and a NW HB-reflector, rather than 2 SE and 1 NW HB-rakes, that would allow to reduce amount of HB-trails, re-ignited with a slow elbow, to one.
I like this idea too. It can be done with 3 SE rakes and one NW reflector just with some pulling and pushing of existing designs. The most south easterly chain of HB's will have to be pushed further away to make space for more resets though.

Well done! It's not possible to place the rake, that shoots gliders in the reflector (the one that is in the middle in your last design), in the most south-eastern position, is it? That would completely solve the problem with resets.

Let's call the remaining trail in the northwest "A1", with "A2" being the other half of the A rake. The SW side in this last design now has B, A2 and C trails.

No, it seems you can't swap A2 and C -- one of the half-bakeries in the C trail gets in the way. I don't see a big problem with moving the C trail as far as you want to the SE, though:

Will those two faraway C gliders have to be built with two 90-degree turns -- a slow elbow/turner constellation followed by a superslow turner constellation? Or is it still possible to connect those up to 180-degree turners in the shooting lane, with really really long half-bakery chains?

Another problem is re-creating a working suppression mechanism for this configuration. The lone A1 glider can be shot down cleanly, but I haven't found a way to create (-3,-6) repeatable junk yet to kill off the C glider pair. So far I've only looked at A1, though, so there might be a clean suppression line that starts at B or A2 -- lots of possibilities left to try.

As dvgrn notes, swapping the order of those last two chains causes a collision. I went back and looked at other 3g collisions but couldnt find anything else that looked suitable. Also I looked for other ways that the HB reaction can reflect a glider 180 degrees, but couldnt find any. (Indeed the very first post of this thread suggests that there is no other way).

If the 180 degree turner method is to be used with this design then every extra reset will require an (8,8) shift of the C salvo, which will require another 8 HB's at the front end. Thus each reset will cost about 70% more than before in terms of ship length. I don't know if it's better to do this, or to try a four glider method, or to abandon the 180 degree turner method for the C salvo. Too many options!

Then it does not benefit to split A into A1 and A2 in the first place. But, as chris_c just pointed out, it may be worth trying 4-glider collisions, that allow to place A2 in the most south-eastern position. In this case, though, A2 glider would have to bypass 3 (!) half-bakery rakes.
