Re: Execution of Old Guns by VariableSpeed Firing Squad
Well there are some interesting guns like p22 etc. but most of the high period above p100 are totally obsolete now.Extrementhusiast wrote:What about for p30n, p46n, etc.?
Anyway I think we need a better gun collection that will include edge shooters, as this is the most common usage of guns.
Re: Execution of Old Guns by VariableSpeed Firing Squad
Strange, very strange! The gadget also works at p75 (and the concomitant small glider duplicator of Grant, on the other thread) but not at p76 and p77: you get an LWSS and MWSS from them respectively! Oh, how much shrapnel they produce!chris_c wrote:I also accidentally discovered that the G>H can be overclocked at p74
Re: Execution of Old Guns by VariableSpeed Firing Squad
Yes, I am writing a little script that compares areas of different gun families and also compares against the old collection. So far I have added families starting from p345, p358, p418 and p482. The p418 is from Kazyan's MunitionsDump. It is larger than the p482 family once the trombone is extended by 8 cells but it gives a nice p79 and a nice overclocked p75 that both appear to be record breakers:Extrementhusiast wrote:What about for p30n, p46n, etc.?simsim314 wrote:I think there is no point to use the old collection up to 1000 now, as the collection is totally obsolete, except of maybe for the low periods.

Re: Execution of Old Guns by VariableSpeed Firing Squad
Belated congratulations on the new GtoH injector/syringe! I've been traveling for the last couple of days, so it was quite a surprise to see all these new developments.Kazyan wrote:Tromboneslide guns are period X+8n. We could get a gun family for X of all numbers modulo 8, to cover all the middlingperiod guns and their factors above 78. So far, we have X mod 8 = 0, 1, and 6.
Here are some fairly reasonable 3 mod 8 and 5 mod 8 ouroborous loops. The version on the left has a longer recovery time due to the addition of the R64  it doesn't seem too likely that another eater can be welded in there to stop the FNG from the R64 output, but don't let me stop anyone. The R64 doesn't change the output glider color, but because of the 90degree turn it does end up changing the mod8 rating:

Re: Execution of Old Guns by VariableSpeed Firing Squad
Once a gun family has been adjusted out far enough, it usually makes sense to rearrange the reflectors so that the gun is only growing in one direction instead of two (for a while, anyway). I assume that will count as a new family?chris_c wrote:I am writing a little script that compares areas of different gun families and also compares against the old collection. So far I have added families starting from p345, p358, p418 and p482.
For example, the p623+8N above can be twisted into a p815+8N that's wider but not quite as tall  and it won't have to grow any taller until after N=18 (at which point presumably it would be time to twist the loop again.)

With any luck we'll always be able to find shorter loops now, with relatively few signals per loop.
Re: Execution of Old Guns by VariableSpeed Firing Squad
Yeah that's going to be a slightly annoying problem. For example, I've added around 10 gun families so far and still the best p841 gun is a p345 with the trombone extended by 62 cells. That surely cannot be optimal. I will try to get the package tidied up a bit and put it up on github.dvgrn wrote:Once a gun family has been adjusted out far enough, it usually makes sense to rearrange the reflectors so that the gun is only growing in one direction instead of two (for a while, anyway). I assume that will count as a new family?
Re: Execution of Old Guns by VariableSpeed Firing Squad
The directory named fixed is a dump of all the guns from Jason Summers gun collection. It doesn't contain any of the recent additions that Kazyan or simsim have been collecting.
The directory named variable contains variable glider guns that I have made or have scraped from the forum (guns by dvgrn and Kazyan I think). In this directory the number in the filename always represents the length of the glider loop and there is a suffix that indicates if any period multiplying method is used.
For example, the file p00482t.lif contains a period tripled p482 gun. At the moment its variants give the smallest gun in 29 cases below 1000. Other suffixes are "d" for doubled and "q" for quadrupled.

It looks as if your code currently overestimates the size of some variable guns:chris_c wrote:At the moment I wouldn't bet very much on these stats being 100% correct. Please post any inaccuracies, inefficiencies or additions in this thread and I will do my best to keep track of them.
Code: Select all
for d in range(100):
area = (x+d) * (y+d)
for p in divisors(base + 8 * d, compression):
add_gun(p * factor, area, "p%d%s_%d" % (base, "__dtq"[factor], d))
area = (x+d)*y
Reflector adjustments can be kept inside the current bounding box height until d=19. Seems as if this kind of thing is likely to happen a lot... This formula could be continued for d=19+ by adding another twist to the loop, with some adjustment to the initial width. If a given gun family actually wins with a multisignal loop, some testing would have to be done to make sure there's actually a configuration with no collisions. Usually that seems to work out okay in practice.
Would it work to add another optional item to the comment line? "grow = [HWHW]" or something like that?
If you did that, you'd probably want "max = 18" for the particular gun family I'm using as an example, since the formula stops working above that point. Technically I suppose it could be "grow = 0..18H, 19..100HW", but that syntax would be a little trickier to support.
I suspect that five or six signals in a loop may turn out to be optimal on rare occasions, possibly even higher. It may be worth adding "p" and "s" at least, or just switching to "x2", "x3"... "x6", which might be good to avoid confusion if any guns ever go as high as x7.
Re: Execution of Old Guns by VariableSpeed Firing Squad
OK I added the p623 to the collection. The commit is here. It improves another 28 guns compared to the old collection and is completely orthogonal to all the guns that I have put in already. But I'm not sure I agree that my formula is wrong in this case. Moving the trombone outwards will increase the bounding box in the west and the south so I think the formula is ok.dvgrn wrote: It looks as if your code currently overestimates the size of some variable guns:
I agree that it is going to be a pain to deal with multibouncing Snark loops. Probably the best solution is to start a new family at the point where the extra Snarks become viable. The problem you mention with compression number and selfintersecting glider loops is something I have thought about but not found any good solutions to. I guess it will be too much trouble to write code that deals perfectly with all possible cases but hopefully my script can be used to pick off the lowhanging fruit and make the number of adhoc cases much smaller.
Maybe you are missing the point about the suffix letter? Adding more signals to the loop reduces the period but the suffix letters correspond to period multiplication, either with semisnarks or a Herschel multiplicators that I found in a post of yours here. Regardless, your idea of using x2, x3, x4 etc is probably a good one.dvgrn wrote: I suspect that five or six signals in a loop may turn out to be optimal on rare occasions, possibly even higher.

My code adds as many signals to the loop provided that it doesn't take the repeat time below the minimum compression:
Code: Select all
def divisors(n, compression):
for x in range(1, n // compression + 1):
if n % x == 0:
yield n // x
EDIT: The highest number of signals I could find in a record breaking suggestion is 7 in this p82:
Code: Select all
x = 79, y = 81, rule = B3/S23

Re: Execution of Old Guns by VariableSpeed Firing Squad
Well, you're right of course. I was giving the name of one gun while looking at another. The horizontalonly increase applies to the p815+8N gun family, next message down from the p623+8N.chris_c wrote:I'm not sure I agree that my formula is wrong in this case. Moving the trombone outwards will increase the bounding box in the west and the south so I think the formula is ok.
The p623+8N family is getting pretty big by the time it hits p823: the checkin says (11468, 'p623__25'), 122x94. The p815+8N family brings that down to (8040, 'p815__1'), 121x67.
The next gun improved in the last checkin was +839 (11904, 'p623__27'), 124x96  increasing X and Y bounds by two. But the p815+8N gun only has to go up to (8174, 'p815__3'), 123x67, increasing in the X direction only:

Well, the ambitious thing to do might be to define the tromboneslide pieces separately from the main gun body, so that a script can actually assemble p623__2 or p815__3 or their lowerperiod variants if any, dropping in multiple signals at the right times. LifeHistory might be one reasonably simple encoding  use state 1 for the main body, state 2 for a sample signal, and state 3 for the trombone slide, or some such.chris_c wrote:I guess it will be too much trouble to write code that deals perfectly with all possible cases but hopefully my script can be used to pick off the lowhanging fruit and make the number of adhoc cases much smaller.
Then most of the testing could be trivially automated  run one cycle, and if the pattern is exactly the same as when it started except for an output glider, then you can declare success and move on. For the cases where something goes wrong, it's probably best not to try to handle it algorithmically  just dump some RLE to an "Errors" folder.
The error pattern might show a correctly adjusted loop, but with just one signal in it. Then someone can look and see if it can be fixed. If not, maybe something has to go in the comments:
#C p903/7 = p129 not possible in this family: skip = 815__11/7
This will probably happen fairly rarely, because usually some other gun family will turn out to have a smaller p129 anyway, or the fixed gun will be smaller, or there will be some tricky custom way to fold the loop that solves the problem, that can be checked in as a fixed gun (?).
P.S. Yes, I was confused about the suffixes  thanks for the explanation.

Even so, at some point you get a better deal by replacing the leftmost Snark with a loop  instead of, or in addition to, the Snark replacement in the northwest. One of the most infuriating things about bounding box optimization is the sad fact that (X+1)(X1)<X^2... which means that you generally make adjustments by adding new columns, if you can, and avoid adding new rows.
Re: Execution of Old Guns by VariableSpeed Firing Squad
I added three new optional fields to the variable gun descriptions: x_slack, y_slack and tentative_comression. For example, the p739 has been checked in as:dvgrn wrote:We can add a Snark loop to each, to get much more efficient guns for higher periods.

The p739 improves 7 guns from the old collection and 12 guns from the p531 family. Also it gives two record breaking sub period guns at p151 and p159 both of which are marked as "tentative" by the script but do in fact work:

I have not added your double Snark twist p981 gun yet. I would like to delay thinking about that for at least another couple of days if possible! In particular the new variable guns have not produced anything stellar in the p8N category. What magic can you come up with by combining the new G>H and old p8 technology?
EDIT: Ooops I missed your second to last message. Let me get back to that stuff in a while. Safe to say that you spotted some other guns where the x_slack/y_slack thing will come in useful...
EDIT2: Added the p815 with 18 units of y_slack here. It beats 5 more of the old guns and 9 from the p623 family. It offers no new tentative guns so it seems that my less ambitious tentative_compression hack is working quite well at the moment.
EDIT3: Oh, the p765 is already double adjustable so the problem of area overestimation already exists at the moment, even before I think about adding the p981
EDIT4: I experienced some tentative guns that appear to be nonviable. See here for details.
EDIT5: Added some more guns. p363 and p441 are nice and small. The p595, p673 and p702 are variants of existing guns with extra Snarks added. The total of records in the variable gun collection is over 600 but I would love to find a glider loop of period 4N that is below 500 ticks in length. No luck so far.
Re: Execution of Old Guns by VariableSpeed Firing Squad
Let's see if I'm understanding this well enough. Starting with the first tentative item, the p117... yes, it does look not quite viable as it stands. However, there's actually just enough adjustability in the size of the added loop to get p117 gliders to squeak past each other, so all we need is a quick game of weldthetailonthebeehive to be back in business:chris_c wrote:EDIT4: I experienced some tentative guns that appear to be nonviable.

Period 8N should be easy to find, since we can keep adding pairs of p8N reflectors, or substituting them for pairs of Snarks, until the timing works out. Just have to start with an evenperiod loop. Let's see, are either of these small enough to be interesting?

Re: Execution of Old Guns by VariableSpeed Firing Squad
I added the p520 by dvgrn. It is the best variable gun between 520 and 584 and it offers outright record breakers at p544, p272 and p280. But really there is no reason not to add an extra signal to the p560 in the old collection to get an even smaller p280.

#C 1) new p272 based on p520 by Dave Greene

EDIT: Hang on I was confusing myself. It's the p592 that beats the p720 (there is no p598 anyway). Widening out the p592 by 16 cells gives a gun that is smaller in both directions than the p720 above.
Re: Execution of Old Guns by VariableSpeed Firing Squad
But does that just mean that the old p640 should be adjusted better, and it would beat this new one? Don't know yet.

Anyway, maybe there's some useful technology here that can be applied elsewhere. The key things on my reminder list as I was putting this together were:
 Replace a single p8N reflector with a 3reflector loop, or vice versa, and it changes the timing by 2 ticks (one for each added reflector).
 Swap a Snark with a p8N reflector and you'll get a 4tick difference in timing. (Very handy!)

Yes both of those look like they will set records. The p640 is good at large periods due to the high amount of slack. The p464 looks like it will set records between 464 and your recent p520.dvgrn wrote:Speaking of p8N and p4Ncompatible technology, here's a small p464+8N
I will make a proper update once I teach the script that the subperiods all need to be multiples of 8 when p8 oscillating components are present.
Other things on the TODO list are:
 Add the fixed guns that simsim and Kazyan have been collecting.
 Find a formula that works correctly with with doubly adjustable loops.
 Make an automated run of Hersrch to make sure no nice Herschel loops are missed.
 Add semisnarks to existing fixed guns to see if they bring any improvements.
(The last two items may have to wait though!)
Also I made a few adhoc guns using p5 and p7 reflectors starting from p415 and p399 respectively:

Still don't know for sure, but it looks like there should be a lot of ways to improve various p8N periods.
