Thread For Your Bellman/Barrister Finds

[Kazyan]

If a catalyst (most likely found with Bellman) could restore the beehive, this would result in a "one-fifth snark". I've tried using Bellman to find one, but with no success, mostly to do with my lack of experience with the search program. Would anyone else more experienced like to have a go?...

Edit: Or alternatively, a "one-third snark":

Sometimes it's just a matter of knowing where to look, isn't it?

Very nice! The repeat time is 43, the exact same as the snark... I bet this will reduce a lot of the gun collection. Good work Kazyan!

I hope so, though signal circuitry is already pretty good--I don't expect a particularly huge wave of improvements.

Here's probably the best-case scenario for the...I'm gonna call this a "tremi-snark" for now unless someone has a better idea, because "one-third snark" will be ambiguous in the future whenever someone wants to build something involving three reflectors. Anyway, its best-case scenario is this reduction of the p135 gun from 67*58 (3886) to 49*45 (2205), taking advantage of that gaping unoccupied corner of the p45 gun.

There will be a few improvements in identical fashion to this, plus now that we no longer need a Herschel to do a period tripling there should be plenty of other possibilities...

You can say that again. The tremi-Snark even makes small guns like the current period 810 gun look a bit oversized -- the old one was 80x49:

I'd still like to get the quinti-Snark working, though. It would make a record-setting prime oscillator pattern a whole lot smaller.

-- It wouldn't be a Mersenne prime, though, and primes of the form 5^k-1 are going to be ... um... kind of scarce -- and the same if you mix in semi-Snarks and do 10^k-1 or 10^k+1. But I'm sure something could be found that's 5^k - 2 or some other workable offset.

I might try a speculative catalyst/catfind search over the weekend, just in case a different tool helps turn something up.

Here's a first run at finding likely reductions by period-tripling a gun with a smaller period. The table below doesn't take into account reductions already found this morning -- the numbers were from the current README.

The comparison is between the bounding box of the current period-N/3 gun and the current period-N gun. In general, the bigger the discrepancy between the numbers, the more likely it is that a tremi-Snark will improve things.

Looking at the first one in the list, tripling the P44 gun, it doesn't look like the tremi-Snark can improve anything. Even an improbably close weld with the old form of the sparker wouldn't improve anything -- and the weld doesn't quite work anyway:

I posted this a while back as a result of a dr search. It's been used in at least one conduit so far, but I don't have time to search for it.

[Kazyan]

At the cost of 5 more ticks of repeat time, this catalyst increments the tremi-snark multiplier by one. It also works for the original snark, which turns it into a color-preserving version of the semi-snark. It doesn't work for augmenting the color-changing semi into a color-changing tremi, though.

At the cost of 5 more ticks of repeat time, this catalyst increments the tremi-snark multiplier by one. It also works for the original snark, which turns it into a color-preserving version of the semi-snark. It doesn't work for augmenting the color-changing semi into a color-changing tremi, though.

(Incidentally, whence did you get that p48 gun? The modern way is to filter a p24 gun using Rich's p16.)

[muzik]

Could there be a way to engineer any n-snark? I would assume such a thing would work by pulling an object like a block from the end to the beginning through some repetitive contraption, where the block would be regenerated at the end again.

Then again, I know nothing about this kind of stuff.

The guns particularly worth targeting with this contraption are those with periods divisible by 64.

[Saka]

I'm not sure where else to put this, but I have some Bellman questions:
1. At what point do filters start at? What is the origin? The center of the search space, top left, bottom left?
1.5 Can someone elaborate what #P does?

2. What setup could I use to find unusual glider eaters?

[dvgrn]

Could there be a way to engineer any n-snark? I would assume such a thing would work by pulling an object like a block from the end to the beginning through some repetitive contraption, where the block would be regenerated at the end again.

There isn't a really simple object that can support an arbitrary number of "pull" operations using just a single glider on a single lane. However, we do have a nice small H->G10 converter, which means we can do a 3fd block pull with just one input signal, or a 6fd pull if you double the input signal first as is done in the current draft HashLife-friendly metacell.

So I guess you might say that the ladder circuit in that metacell is the closest thing we have right now to an engineered (1/n)-Snark. It would have to be rebuilt from the ground up to produce an output for every n inputs -- the output signal would be split and sent to rebuild the block in its starting position, but more importantly an output glider might be created with every pull operation, with a bank of n-1 eaters to stop each output until the count gets high enough.

That's all just speculation -- there's probably some reasonable way to do it, but I think it's safe to say there's no known really compact mechanism, and it won't be able to accept input signals at anywhere near 48-tick repeat time.

For any given multiplier and input stream, there will probably be a custom solution that's smaller than a general (1/n)-Snark. Just to give an idea, here's a custom period septupler from a long time ago:

Jason Summers responded with a few other high-multiplier mechanisms:

Here are a couple of variations of this that result in multipliers that aren't a multiple of 7. There are probably a lot of other variations of this. These reactions are somewhat sporadic, and I don't know if they are much use in general.

It's also possible to have a Herschel send gliders backward into a circuit it has just passed by, or forward in some cases I think, to create boat-bits that block some number of following Herschels. The available multipliers get complicated quickly when you have multiple boat-bits fed by multiple glider outputs -- I seem to recall it's pretty easy to produce Fibonacci numbers, for example.

The idea is for each boat-bit to be placed so that it kills off the previous Herschel in the chain before it can produce the glider that would otherwise create the previous boat-bit.

It might be interesting to see how much smaller this kind of structure could be made now, with syringes and such -- there may well be an algorithm for chaining boat-bit suppressors that will produce any arbitrarily-chosen multipler. It will be a lot easier to experiment now that we have Snarks (and the various multiplier-Snarks, maybe!) to help get gliders onto the right lanes.

The only other case I remember offhand is a custom count-to-19 mechanism made for the Infinite Conduit.

I am not trying to win the compactness contest here, but this is a 5-snark (with non-trivial periodicity constraints):

it can be altered to make all 2^a3^b(2^c3^d +1), which covers many, but not all, primes. To get to 11 or 23, you can feed into the input a gliders to get 12-1 or 24-1. These constructions are large though.

In most cases where the SNG-producing third is removed, one needs to guard the catalyst in question using other catalysts, which I do here using grey cells for minimal obtrusiveness.
