Construction Challenges and Ideas

[AlbertArmStain]

If there’s a linear propagator then there needs to be a quadratic propagator. I also want to see a replicator that can emulate an elementary CA (no, I’m not taking about using the 0E0P metacell for any of these)

There is in fact a "quadratic propagator" (DOGun SaGaQR, in one of its configurations).

Either DOGun SaGaQR or (with more effort) the linear propagator could be adjusted to emulate an elementary I-dimensional CA. The linear propagator already does emulate one particularly boring elementary ID CA. Are you saying that you're looking for something that could be programmed / adjusted to emulate some particular range of elementary CAs?

I'm definitely looking for something that can be programmed, I don't know how you could interpret it differently.

Well, theoretically speaking, it's possible read what you actually said, literally. The linear propagator is a "replicator that can emulate an elementary CA".

I was pretty sure you didn't mean that -- but then the question was whether you were thinking of emulating some other single, specific elementary CA (just a more interesting one than what the linear propagator emulates) -- or if you really wanted it to be programmable.

The thing is, a programmable self-destructing linear-propagator-type pattern is going to have to be quite a lot more complicated than the linear propagator -- which doesn't need self-destruct circuitry, it doesn't need circuitry for communicating with neighbors, and it doesn't need editable lookup tables to determine the rule being emulated.

it would be a lot easier to build a programmable linear propagator in 2023 than it was in 2013, a.k.a. 4 B.C.S. (Before the Coming of Slsparse) -- when I had to build all the slow-salvo recipes by hand one still life at a time. But even in 2023, a programmable linear propagator seems like it will have to end up looking kind of like a stripped-down version of the 0E0P metacell -- it needs all the same kinds of pieces, just maybe not so many of them.

For that matter, it would be easier to build something like the 0E0P metacell in 2023 than it was in 2014 through 2018. We could consider a redesign of the 0E0P metacell, maybe cutting it down to emulating just the Life-like subset of rules, and end up with something that Golly could run through a full cycle in days or weeks instead of months or years. Maybe that design could also support 1D CAs as an option.

The usual limitation would presumably remain in force -- no B0 rules need apply.

That definitely makes sense. While we’re talking about the 0E0P metacell, has anyone tried reducing 0E0P metacell or maybe make it more Hashlife friendly? This would be way easier to do now that DOGun SaGaQR exists, should we give reducing the 0E0P metacell a try?

A collection of true period N glider guns for N = 2023, 2022, 2021, ..., 1999, ... where the period-N gun is not allowed to rely on reactions or mechanisms that were discovered later than year N. (E.g. the Snark cannot be used for periods N < 2013, but it can be used for N >= 2013.)

At some point, likely between 1975 and 1995, the guns becomes impossible to construct. Where exactly does that point fall?

p1980 (30x66) should be possible by multiplying the period of a GGG, something I suspect was possible by 1980. The duplicator on the Wiki is dated 1993, though, and I can't find an earlier example. The proof of universality featured in Conway's book in 1982 likely would've used something of the sort.

Here's a p1980 extension of the p60 glider shuttle found in 1971:

Code: Select all

x = 275, y = 247, rule = B3/S23
2bo4bo$2ob4ob2o$2bo4bo241$256bo$257b2o8bo4bo$256b2o7b2ob4ob2o$267bo4bo
!

. p1978 (46x43) might be possible with p46 technology depending on how much of it was known at the time, but I kind of doubt it. p46 guns were known about by 1971.

[dvgrn]

As far as a continuous series of guns starting with p2023 and working backwards, I think there's a hard stop after no more than twenty years. 1994 almost certainly wasn't buildable, and 1993 definitely wasn't.

In 1995 there would have been no trouble building a Herschel-based p1995 gun. Same for any later year.

Offhand I can't think of how someone would have built a p1994 = period 997 * 2 gun in 1994.

But it's a definite fact that no true-period glider guns of any odd period at all were known before 1995 -- so 1993 is definitely out.

Very nice! I'm not sure how I missed that idea. Here's a similar design at p1980 I made by stapling p30 guns together in a similar way:

Unlike block arrays, the pond and tub arrays remain stable when you remove a single pond/tub. This makes construction much easier since you can build the array one pond/tub at a time.

Related to beehive arrays, this four-glider collision settling into a three-beehive stack looked very impressive to me when I saw it in a log (but I don't know who found it):

Unlike block arrays, the pond and tub arrays remain stable when you remove a single pond/tub. This makes construction much easier since you can build the array one pond/tub at a time.

No, I don't think so:

I believe this can be used to solve pond arrays (add beehives one at a time, then convert all beehives into ponds simultaneously):

Constructivity ... pond and tub arrays

Tub array construction is far easier if tubs are spaced two cells. With the added benefit that you can construct any arbitrary void/tub pattern ( allowing it to be used as a memory device ) line by line, by LWSSs,

PS: By the same token, it also allows for a - albeit slow - display device. Erasing/refreshing is left as an exercise for scholars.

Here’s an idea similar to the black hole idea:

•An engineered self-repair spaceship

It's very easy using xWSSes and a rake. The rake doesn't occur naturally so I count it as engineered.

Could be tightened up quite a bit, if anyone wants to work on a Pointless Optimization.

not pointless :

Oscillators : 155X155

Can anyone construct a p159+3n c/3 rake (or an adjustable rake with an even lower base period)? There is an engineless p159 rake in the moving objects collection (velocity-c3/rake-c3-p159.rle):

Code: Select all

#C Engineless p159 c/3 rake.

I think an adjustable-period rake would probably need synchronization of these gliders and some way to extend the period. Presumably the backward LWSS stage could be extended to increase the period. Unfortunately, such a construction is beyond my ability.

My goal is to have a more explicit construction for the Game of Life Status page. The page currently links to the following pattern that "demonstrates that all periods 144 and higher can, in principle, be constructed. (Actually, this can probably be reduced to around 90-100)":

Code: Select all

#C This demonstrates some reactions which could be used
#C to build a c/3 spaceship or rake of any period 144 or higher.
#C Completing such a spaceship would require lots of glider
#C duplicators, turners, and repositioners. A sufficient variety
#C of these objects is known.

PS: By the same token, it also allows for a - albeit slow - display device. Erasing/refreshing is left as an exercise for scholars.

Code: Select all

...

Erasing a tub is quite easy - just use 1 LWSS:

Code: Select all

x = 74, y = 13, rule = LifeHistory
.C4.C4.C$C.C2.C.C2.C.C$.C4.C4.C2$51.4E5.4E5.4E$.C4.C4.C39.E3.E4.E3.E4.

4E$19.E3.E4.E3.E4.E3.E$19.E8.E8.E$20.E2.E5.E2.E5.E2.E!

Hence we can get this:
