SlowSilver Demonoid

[EvinZL]

APG on Discord proposed an idea for "SlowSilver Demonoid". The design is based on that of the 0hd Demonoid: have several splitters that shoot gliders onto one track, creating a glider stream with smaller gaps. This contrasts with the QuickSilver Demonoid, which creates a glider stream with smaller gaps by overclocking a Silver reflector.

A Callahan G-to-H plus NW31 provides exactly what is needed for a Demonoid: a 180 degree output lane, and a 90 degree output lane in the right direction. NW31 can insert gliders 15 ticks behind or 66 ticks before an existing glider:

Using a large number of Callahan G-to-H+NW31s (I'll just call this CGNW31s), we can create a wide variety of salvos including spacings as low as 15 ticks. By using a larger number of reflectors, this deisgn has the advantage over the 0hd Demonoid of having access to more salvos. This also means we should run a search for this set of salvos. Since the CGNW31s can be resued for multiple cycles, more CGNW31s does not increase the construction cost. Using more than 34 CGNW31s should not have much of an advantage over using 34 CGNW31s.

In a SlowSilver Demonoid that resuses reflectors, the CGNW31s will have a spacing of 55 full diagonals:

This is because the CGNW31's 180 degree stream is 55hd offset from the input stream. The spaceship will have a displacement of 55fd per cycle.

Now there are two technical points that are required for the SlowSilver Demonoid:

• There is a block very close to the glider stream. The best way to solve this is probably create the block using the single-channel salvo, which is likely even cheaper than creating a generic block using a 90-degree salvo.
• The trailing CGNW31 needs to be destroyed. This is an issue that occurs in many self-constructing spaceships. A solution is to have an offset trailing glider that reacts with the CGNW31 and a couple of still lives to produce only a copy of itself shifted 55hd at the right timing.DONE!

So, let's build the SlowSilver Demonoid!

There is a lot of delay built into the reflector and splitter, which is to prevent the reflector and splitter from having to be too far from the CGNW31 and hence being expensive to build.

As for the salvos, with a minimum glider spacing of 15 ticks, there are four valid blocks. These are the pi-explodable block, honeyfarm-explodable block, big spark making block, and pullable block. All of these are valid elbows which can be used by a 15 tick salvo arm. Note that the pullable block turns into a honeyfarm block if the second glider is 16 ticks or more after but produces a unique explosion when the second glider is 15 ticks afterwards.

Here is a destruction assembly that works...

Looks good! The old 0hd Demonoid constructor-arm unit was 247 cells including the destruction assembly, 46 objects including dependent syringe pieces. This SlowSilver one is 230 cells, 40 objects, and all cheap old-Spartan stuff with no eater2 or beehive-with-tail. And I double-checked the timing of the trailing cleanup glider, and (not surprisingly) it does correctly match the speed of the recipe gliders.

It will be interesting to see how good the 0hd recipes can get, when N consecutive gliders with 15hd spacing are allowed. Even for single-digit N, that search space is humongous -- I kind of suspect we'll just end up picking the largest N where we can do a reasonably exhaustive search for elbow ops.

The largest N may not be optimal for a lowest-population SlowSilver Demonoid, though. If, let's say, glider-octuple elbow ops can't be found that save at least 46 gliders in the total "0hd-8g" recipe, compared to the best recipe for "0hd-7g" glider-septuple elbow ops, then it's cheaper to have just seven Silver reflectors on each side.

... Yikes, Golly HashLife really isn't going to be very happy with this project. Not sure about StreamLife -- how well does it handle boustrophedonic gliders at 55hd offsets?

Lowest population i definitely an attainable goal for the SlowSilver design. For the SlowSilver build, there's another possible goal of lowest period self-contructor. By using like 40 GCNW31s/side to basically use the (say 7g) toolkit many times per 575 generations could definitely reach a low period. However, HashLife will hate the lowest period SlowSilver even more.

A little more thinking along these lines: I don't think that 40 CGNW31s will ever be necessary, but maybe I'm thinking wrong somewhere.

The recipe gliders can theoretically be arranged in groups of up to 34 gliders 15 ticks apart, with a 66-tick gap every 576 ticks. In practice it will be up-to-N gliders (for our chosen N, whatever that is) followed by a gap just long enough for the reaction to stabilize, then another up-to-N gliders, then another pause for stabilization, and then maybe another up-to-N gliers plus stabilization, and finally the required 66-tick gap.

How many of these sequences will fit in a 575-tick cycle? -- or should we say 576 ticks? 576 is maybe a bit more HashLife-friendly, which is why the original Gemini had 576-tick spacing between its instructions instead of 575 ticks.

If the search prioritizes elbow ops that are packed close together and are quick to recover, then we could probably fit two or three cycles of operations in each 576-tick cycle. For example, if we search for elbow ops made of groups of four gliders with an average of 30 ticks between them, plus a 72-tick recovery time, then we could reliably pack three elbow ops into each 576-tick cycle -- which would mean we'd need twelve CGNW31s on each side of the Demonoid.

Four gliders with an average of 40 ticks between them, plus a 128-tick recovery time, would be a much larger search space so it will probably contain more efficient recipes -- but we can only pack two elbow ops per 576-tick cycle. On the other hand, that will mean we'd only need eight GCNW31s on each side. I guess we might choose a different option depending on whether we're optimizing for just population, or just period, or both.

-- Did I get any of that math wrong? Wouldn't be surprising if I did.

[calcyman]

-- Did I get any of that math wrong? Wouldn't be surprising if I did.

The cycle time will need to be larger than 576. By my calculations, it will need to be at least 575 + 14 = 589.

Specifically, if we split the T-tick cycle into a number of 15-tick 'bins' followed by a 'refractory period', and allocate each bin to a different reflector, then it's possible for two gliders entering the same reflector to be T-14 ticks apart (if the first glider is at the end of its bin, and the second glider is at the start).

If we opt for a cycle time of 640, then we could have 38 bins of 15 ticks each, followed by a 70-tick refractory period. But yes, that's still not quite 40.

Well, having 100 reflectors won't really hurt anything, right?

Note that the block and boat (pink) of one reflector are very close to the next reflector (white). This means that it could be more efficient to build them together with the next reflector. There are a couple still live (yellow) that block the lanes to the boat, but slmake should be able to work around them.

[dvgrn]

The cycle time will need to be larger than 576. By my calculations, it will need to be at least 575 + 14 = 589.

Specifically, if we split the T-tick cycle into a number of 15-tick 'bins' followed by a 'refractory period', and allocate each bin to a different reflector, then it's possible for two gliders entering the same reflector to be T-14 ticks apart (if the first glider is at the end of its bin, and the second glider is at the start).

Yeah, I see the point about successive gliders entering any given CGNW31. The more leeway any given glider has to move forward or backward in its "bin", the more ticks we have to add to the cycle time to make sure that there are always at least 575 ticks between each pair of gliders. -- Unless we want to live dangerously and just forbid any sub-575 spacings at compile time, anyway!

If we opt for a cycle time of 640, then we could have 38 bins of 15 ticks each, followed by a 70-tick refractory period. But yes, that's still not quite 40.

I'm not sure I like that way of thinking about these recipes. "38 bins of 15 ticks each" means to me that a glider would have a free choice of any location in its bin. But since gliders have to be 15 ticks apart, if you move a glider in one bin, you also have to move the gliders in all following bins.

Now, technically we could have 38 bins of 15 ticks each, if the gliders are only allowed to be present or absent in a fixed location in each bin, rather than being allowed to move. As simsim314's Remini showed, it's quite possible that this kind of "binary SlowDemonoid" would still allow for universal construction -- but I doubt that recipes like that would be as efficient as we want them to be!

Let's say we're talking about a 768-tick cycle with up to five gliders per elbow op, and three elbow ops per cycle (let's say for the model where we're trying to cut period to a minimum rather than population).

In my way of thinking about it, each elbow op will be made up of up-to-N gliders with at least 15 ticks between them. The first glider in the first elbow op will be at position 0, fired by the last CGNW31 in the chain on each side. Presumably the first glider in the second elbow op will be placed around position 256 -- i.e., 256 ticks after the first glider. And the first glider in the third elbow op will be around position 512.

But there's actually a little wiggle room there. The only hard requirements are that

1) successive gliders fired by any given CGNW31 can't be closer than 575 ticks apart. There's 768-575 = 193 ticks of wiggle room, and again we can "live dangerously" if we want to -- i.e., use recipes that can't be strung together in a standard way in all possible combinations, but almost all combinations work fine and we just tell the compiler to avoid the bad combinations.

2) the last glider in the third elbow op can be placed no later than position 768 minus 66 = 710 ticks.

If we pick a cycle time as large as 768, 193 ticks is a lot of wiggle room so #1 shouldn't be much of a constraint, but for cycle times in the low 600s this could really cut down on the search space. It seems like it will be tricky to find the optimal cycle time.

However, this only applies to to the period-minimized SlowSilver Demonoid. Which to me suggests that we should start by doing nice simple searches that assume just one elbow-op recipe of N gliders in, let's say, a 1024-tick cycle. The spaceship will end up bigger, but the population will be the same (or slightly smaller, because we can use lots of elbow-op recipes that wouldn't fit the constraints for a tighter cycle).

Well, having 100 reflectors won't really hurt anything, right?

My guess would be that somewhere well below 100 CGNW31s, the population will start going up as you add more reflectors. But I guess it's an open question where exactly the "diminishing returns" turn into "no returns".

Probably I've failed to explain exactly what I'm suggesting.

The way that I'm envisaging it, within each cycle we can have absolutely any stream of gliders that fit within the 570-tick window and adhere to the spacing requirements: in other words, any subset S of {0, 1, 2, ..., 568, 569} with the property that no two elements are separated by < 15 ticks. There's then a 70-tick refractory period before the next cycle begins.

The 'bins' approach comes later as a method of assigning those gliders to reflectors. It's based on the observation that since any two elements of S are separated by at least 15 ticks, they would land in separate 'bins' if you take the integer part of division by 15. This means that we can assign gliders to CGNW31s without having to actually think at all -- just assign them based on floor(T/15).

For example, if we wanted to fire gliders with timings of S = {13, 42, 69, 84, 99, 120, 147}, then they'd get assigned to reflectors {0, 2, 4, 5, 6, 8, 9}, respectively. Other reflectors, such as 1, 3, and 7, wouldn't issue a glider on this particular cycle.

As I see it, it's better than the alternative of assigning gliders to reflectors based on the ordinal index of that glider in the cycle -- because if you do that, you'll encounter problems if cycle N has most of its gliders bunched up towards the end of the cycle, and cycle N+1 has most of its gliders bunched up towards the start. Whereas the floor(T/15) binning guarantees that each reflector will spend at least P-14 ticks between issuing gliders, where P is the cycle period.

[EvinZL]

I ran some experiments on how many slow gliders the SlowSilver Demonoid would require. The best recipe found has 381 gliders and is attached here. The sources seem to suggest that the 0hd Demonoid is more expensive at 540 slow gliders, so this is definitely an improvement. This version assumes a reexisting hand an pushes it 55fd while creating the circuitry.

Interestingly, on some variants Hippo69's version of slmake cost more than the original slmake. For this variant, both versions happen to give the same cost.

Getting down the cost of this could be one of pslmake's first achievements.

EDIT:

at this point, we could create a slowsilver demonoid with the gp design of the 0hd demonoid and it will be lower pop, just a lot slower
0hd demonoid dethroned by steampunk?
The 0hd demonoid seems to operate at around 5 glider pairs/slow glider, or 10 fast gliders/slow glider
so a 0hd two-arm slowsilver would be around 1900 glider pairs, for a population of around 19000 and a period of around 1100000
with more arms the population increases sligtly but the period decreases a lot
or using a n-gliders-at-a-time instead of a 2-gliders-at-a-time contructor, an even lower pop may be attainable

EDIT2: I forgot the NW31 block will be made using single channel fast salvo; this means only 379 slow gliders are used. Also the cost of creating the NW31 block and pushing the elbow is not included. Right now I can't upload the salvo, I'm on a phone.

EDIT3: In the current slow salvo, the marked objects are built involving a reaction that comes uncomfortably close to the recipe lane:

However, it seems likely this can be solved using semi-manual slow-salvo generation.

[Hippo.69]

Interestingly, on some variants Hippo69's version of slmake cost more than the original slmake. For this variant, both versions happen to give the same cost.

Getting down the cost of this could be one of pslmake's first achievements.

Yes, if you used slmake just for the pattern in the attachment, I am not surprised. The difference is mainly in processing "longmoves" ... the spanning tree reduction strategy. But in the pattern, everything is so close together, there are rarely "longmoves".
And pslmake should definitely have the search advantage so let us see the gain.

Yep, it generated split moves (# clusters) + few reduce moves ... with no chunking involved so esentially no difference except the randomness of the eager strategy (a bit different order of selecting targets).

The first version (r23_forceddonkey) gives salvo of size 356.

Code: Select all

x = 45576, y = 45570, rule = B3/S23

I have not copied the results so I should rerun it ... r_0 gives the same 356 size. r1 gives 376.

Code: Select all

356 r23_forceddonkey, r_0, r10, r11, r12, r13, r14, r15, r16, r17, r18, r19, r20, r21, r22, r22_forceddonkey, r4, r5, r6, r7, r8, r9 
376 r1, r3
470 r2 ... extremally slow

Oh the difference (except r2) is only in not moving the block at the start by 38,44 so 6 difference SW.
Is the exact position needed, 6 difference SW(* NW) requires 4 gliders.

Oh the W boat one time reflector require this position. If we would build this reflector of the next silver*, we would not be such constrained, but it could be more expensive as it is not that close to the oher clusters. Oh seed of destrucion used requires this exact positioning ... so 376 is the result.

I have no experience with this ship, but is it fine that it is construced from SE and is destroyed from NW?

Oh may be I start understanding the layout ... there will be several =? equal silver gadgets in SE and mirror/shifted the same amount in NW.
There will be glider stream recipe alternating among them with slow progress NE and closed on the SE/NW ... must be synchronized to one line will be G0 joined salvos from duplicated recipe gliders building next silver gadgets. When the gadget is finished, last a bit off glider closing the recipe stream runs to seed of destruction of the W/most gadget what finishes one ship move forward by one gadget width (and the other side is exactly in the middle of the recipe). OK

The reflection distance of recipe stream is half the distance the ship moves in one round 55/2 (color changes). And the distance to the seed of destruction gliders should be the same, yes, it is:)

I have not looked at G0 "fast" arm, but I bet good agnosticize (after norm 1 optimization) (with alternate lines and phases ... fortunately we are %2 at most) will give it "packing" choices... .

I do not understand the reasoning to "organize" the stream G0 merging. The calcymans method easily determines which gliders are hitting which silver reflectors (their order from NE). This determines the reaction, required waiting time and therefore required timing for the next recipe glider GO fast emission. (SLSparse has some G0 fast arm incorporated (working for at most %2 phases) so we have at least some recipe to start with ...).

Oh we should decide how many active reflectors in a row will be required ... to be able to finish each G0 fast emission.
Oh looking at G0 fast recipes produced by slsparse ... seems they use minimal time difference 90 in the basic setting. OK smaller recipe by pslmake and small G0 fast translation is the starting point and the relation among G0 fast emission/move length and number of silver reflectors should be decided. So the problem is again converted to "packing a recipe" but now requiring G0>14 ticks arm (and good slow salvo decomposition).

OK ... I will still focus on the binary arm research watching pslmake progress.

Oh OK, if I understand it correctly 40=(14+575)/15 rounded up reflectors (+1 in construction) on each side + could provide any G0>14 salvo. If we restrict salvo in some way, smaller number of reflectors could be possible.
Seems to me any instruction requiring less G0>14 gliders then is number of working CGNW31s on one side would be doable, we always can check what is first tick the first glider can be issued such that all required CGNW31s are ready. I would personally prefered more CGNW31s if it makes the distance among the G0 lines much smaller.
What would be usefull for the further processing is the G0>14 stream divided to indivdual arm instructions (among which an arbitrary/partity constrained pause could occur (>100 0%2 types of constraints)).
Scheduling such inputs to different number of CGNW31s (starting instructons eagerly in first possible tick) must be an easy task and we can choose the best looking result.

[calcyman]

The first version (r23_forceddonkey) gives salvo of size 356.

309 with an early version of pslmake (which uses the same dataset as slsparse, so it's entirely attributable to the beam search algorithm):

This took 5 minutes of wall-clock time using 8 threads and a beamwidth of 20, so I'd say that it's an acceptable speed.

[calcyman]

The first version (r23_forceddonkey) gives salvo of size 356.

309 with an early version of pslmake (which uses the same dataset as slsparse, so it's entirely attributable to the beam search algorithm):

This took 5 minutes of wall-clock time using 8 threads and a beamwidth of 20, so I'd say that it's an acceptable speed.

292 by increasing the beamwidth to 100 (causing it to take 13 minutes of wall-clock time). This parameter really does let you tradeoff between optimality of result and speed:

Code: Select all

x = 37806, y = 37802, rule = B3/S23

In an actual SlowSilver Demonoid, one stage of the above salvo would look like the following:

Code: Select all

x = 115, y = 136, rule = B3/S23

This makes it invalid due to the salvo hitting the previously constructed CGNW31.

Also, secondly, the block right next to the construction lane should not be built using slow salvo, instead using a single-channel recipe.

In addition, depending on the singlepchannel toolkit, some intermediate stages in the construction might be a bit close to the construction lane.

Oops even the loaf is destroyed by the construction, seems the NW boat should be build "one reflector" earlier. Maybe it helps. "AVOID" technique in pslmake?

Something like this could work ... oops no, boat was problem as well ... (with the block built another way) ... unfortunaely that would mean two reflectors in construction as the eaterless reflector would be useless.

[calcyman]

In addition, depending on the singlepchannel toolkit, some intermediate stages in the construction might be a bit close to the construction lane.

I've implemented a 'clearway' feature in pslmake where you can specify an area (in blue) in which no intermediates are allowed to exist. Transient sparks can enter this area, and of course gliders can pass through it, but after each slow glider impact, the clearway must be empty. I added this feature mostly for the benefit of the self-modifying DBCA, but these Demonoids are another place where it's helpful.

Here's the result (325 gliders), which I've converted to LifeSuper so that you can see the envelope more clearly (to @dvgrn: the envelope is a bit imperfect through, since gliders sometimes erase parts of it -- am I using LifeSuper incorrectly? I want to show the envelope of the reaction after the gliders have impacted, but leave out the glider trails themselves):

It's using a data library that's really not designed for these 'reverse-edgy' recipes, though, so I imagine that we can do much better than 325 gliders.

Here's the pslmake stderr output; note that it firstly finds a 328-glider solution, but continues searching (and finds better solutions with 327, 326, and 325 gliders in quick succession) until it reaches a state where it's impossible for the beam search to find any further improvement:

[dvgrn]

Here's the result (325 gliders), which I've converted to LifeSuper so that you can see the envelope more clearly (to @dvgrn: the envelope is a bit imperfect through, since gliders sometimes erase parts of it -- am I using LifeSuper incorrectly? I want to show the envelope of the reaction after the gliders have impacted, but leave out the glider trails themselves...)

There isn't a "once LifeHistory, always LifeHistory, spreads by birth to neighbors" state -- it seemed more important to be able to erase history trails with no-history active reactions. So the gliders erasing parts of the envelope is pretty much the behavior that you'll get with state-13 gliders and a state-1 target.

To get something like the effect you want, you could add a line showing the boundary of the clearway. State 8 followed by state 3 will convert gliders to leave LifeHistory trails only after the boundary, without any with-history reactions finding their way back to make a mess on the other side of the line.

I would generally also mark the target locations in state 3, so that you can see the plan before you run the pattern -- but that's optional of course:

Code: Select all

x = 41654, y = 41601, rule = LifeSuper

[calcyman]

Here's the result (325 gliders), which I've converted to LifeSuper so that you can see the envelope more clearly (to @dvgrn: the envelope is a bit imperfect through, since gliders sometimes erase parts of it -- am I using LifeSuper incorrectly? I want to show the envelope of the reaction after the gliders have impacted, but leave out the glider trails themselves...)

There isn't a "once LifeHistory, always LifeHistory, spreads by birth to neighbors" state -- it seemed more important to be able to erase history trails with no-history active reactions. So the gliders erasing parts of the envelope is pretty much the behavior that you'll get with state-13 gliders and a state-1 target.

To get something like the effect you want, you could add a line showing the boundary of the clearway. State 8 followed by state 3 will convert gliders to leave LifeHistory trails only after the boundary, without any with-history reactions finding their way back to make a mess on the other side of the line.

Oh, no, I do explicitly want to see any with-history reactions make their way to the south-east, if they exist. Effectively I want to see the full envelope, but only the envelope caused once the gliders have interacted.

Maybe I'll need to write a new ruletable for this purpose, then: one that's similar to the current behaviour but where history trails are never erased even if a non-history-leaving glider passes through them. There will need to be 3 different types of live cells (non-history-leaving, non-history-leaving but on top of a history background, and history-leaving) and 2 types of dead cells (vacuum and history), so 5 states in total. The 'permute' ruletable symmetry should make this quite succinct, I imagine. I may even increase this to 10 states by adding a 'marked' layer, so that we can show the intended destination pattern (as you suggest) as well as the original clearway.

I created a 8-state rule implementing this: RULE:LifeHistoryAPG. This rule was designed to be backwards-compatible with LifeHistory and LifeSuper, so calcyman's pattern can be run by changing the rule to LifeHistoryAPG and running.

Here's the final envelope:

I is not backward compatible ... even states should be dead while odd alive. 6 is problematic.
At least the starting border line reacts in the given example. I do not know how it should look like .... OK deleting the line helps ... so the 5,7 "gliders" did not left the trail, but 7 left the mark, and 1,3 spreads leaving trail and 3 lefts the mark. What should 6 do?
Oh OK no trail have to let state as it was so it should remember history state, while trail always sets history ... I would just prefer use 9 instead of 6.
(We could use different history dead cells depending on the dead duration ... if we have empty slots..., but swith off/on of trailing would be nice addition)

To get people thinking about a toolkit...

I implemented a search with basically no code and got some results. The format is each slow salvo is encoded as a tuple (a,b,c,d,...) where a is the position of the block (-2 for the big spark, -3 for the pi, -4 for the hf, and -5 for the block pull), and the remaining items are the glider spacings. The results are those with ash of at most 10 cells, with possibly extra escaping gliders to the two sides, and that leave behind something for future gliders to collide with. I scanned through the first file and there were some usable eblow moves.

Even with a basic python Golly script, these searches for 3 or 4 gliders+block take less than 4 hours to complete. Also, there are some 5-glider salvos, because the searches starting from the block pull start with a spacing of 15 to prevent redundancy.

It would be nice to have a Lifewiever file to show example reactions for each input type configuration to document the encodding.
