would it be ethical to create a thread for still lifes

just sayin'

The rules tells u whether it is necessary for one

Is it possible to build a rake gun where the gliders used to synthesize each rake come from the previous rake?

Yes, in fact I believe abhpzta has constructed several such objects in OCA.

Why is the clock so rare? It's rarer than the pond, despite having less cells and fitting in the same area.

[Ian07]

Why is the clock so rare? It's rarer than the pond, despite having less cells and fitting in the same area.

Mainly because the pond has more and smaller predecessors than the clock:

Code: Select all

x = 3, y = 3, rule = B3/S23
bo$2o$2bo!

But the clock is rarer than the ship, which does not seem to have any predecessors that are smaller than the clock.

[Jackk]

I assume the ship is so common mostly since it's part of Herschel debris.

[dvgrn]

The two measurements that seem relevant to clock vs. pond, or clock vs. ship are seed size and glider synthesis cost.

It so happens that you can hit a blinker with one glider and get either a pond or a ship.

You can't hit any small ash object with a glider and get a clock. I'm not sure what the smallest constellation is that produces a clock when you hit it with one glider, but I bet it's fairly big and improbable.

Similarly, ponds and ships can be created by colliding two gliders. You need four gliders to make a clock. Basically, the clock just happens to be a relatively weird, delicately balanced and unlikely mechanism.

If size was the only measurement that mattered as far as likeliness of appearance, we wouldn't have pulsars.

How do you find conduits? Whenever I try to perturb stuff by putting blocks and eaters around it, I just get useless things like these.

How do you find conduits? Whenever I try to perturb stuff by putting blocks and eaters around it, I just get useless things like these...

The first rule -- that I at least would like everyone to follow -- is never to just start with a pi-heptomino or R-pentomino or whatever, at T=0.

Instead, go to the Elementary Conduits Collection and pick out some common conduit that produces whatever object you want to start with. Drop in whatever input is required, run the pattern until it builds the object, and then start experimenting with adding catalysts. If everyone would do this, it would save untold hours' worth of people building non-useful non-conduits.

That said, a lot of the low-hanging discoveries have already been found, so the odds are that if you just drop blocks and eaters near things, you'll only run into conduits that are already known. It's always possible that you'll come up with something new with just manual searches, but the odds are heavily against you. If you really want to find conduits, it's probably best to invest the time in learning how to use one or more search utilities -- catgl, ptbsearch, Bellman, CatForce, or maybe CollisionsSearch.

That last one could be very interesting because hardly anyone besides Guam has ever used it. Guam was able to find quite a few new conduits with it, including the first semi-Snark.

What's the chance that there ends up being no stabilization for the P41 wick at all?

[dvgrn]

What's the chance that there ends up being no stabilization for the P41 wick at all?

Seems very low to me, given that we already have perfectly good stabilizations for the p41 wick. They're just not true-period stabilizations:

I'd be pretty surprised if there was absolutely no way to split a signal at p41, to get a true-period p41 gun. Maybe the p41 gun will be a loop of 2c/3 wire with as-yet-undiscovered elbows, and an attachment on one elbow that spits out a glider when a signal goes by. Or maybe it will be some huge asymmetrical thing that happens to release gliders at one edge -- maybe not findable until we have a million-qubit quantum computer, but still Out There Somewhere.

Current search technology might even be able to find something like that, with a months-long distributed search -- no way to tell without trying. Seems like the signal elbow might be easier to find than the splitter, but that would at least get us a p41 oscillator (and probably the other unknown periods as well).

What kind of pattern is this? According to the LifeWiki, a wickstretcher is a spaceship-like pattern that stretches a wick that is fixed at the other end, but here, we have an oscillator-like pattern that extends a wick that moves at the other end.

What kind of pattern is this? According to the LifeWiki, a wickstretcher is a spaceship-like pattern that stretches a wick that is fixed at the other end, but here, we have an oscillator-like pattern that extends a wick that moves at the other end.

I think the term you're looking for might be extruder. We have the old traffic-lights extruder (which I hope someone rebuilds with stable circuitry at some point) and the triple Snark-wick extruder in Golly's Patterns/HashLife -- and now this switch engine extruder. Or is it a "Cordercolumn extruder"?

[wwei23]

and the triple Snark-wick extruder in Golly's Patterns/HashLife

Wait, explain the wick part? Snarks are stable on their own.

Or is it a "Cordercolumn extruder"?

I just called it the wiggler/wriggler/squiggler, because that's what the switch engines looked like they were doing when they were all stacked like that.

Has anyone constructed a caterpillar based on Herschel conduits-- maybe, say, Fx77?

[dvgrn]

Has anyone constructed a caterpillar based on Herschel conduits-- maybe, say, Fx77?

Nope. It's been talked about some, and occasionally something like Golly's Patterns/Life/Breeders/p100-H-channel-breeder.rle gets constructed.

An Fx77 Caterpillar would be somewhat difficult, in spite of the re-usability of the spine and the easy availability of gliders. Maybe it would be a bit easier with Kazyan's Spartan Fx77 variant, where you can build a pond instead of an eater (but then you have to build more eaters to catch the gliders, unless you're going to use them).

Part of the problem is that Herschels are so fast. In an Fx77 spine they travel 25c/77, much faster than c/4, so if the spaceship is going to travel that speed you'll have to use a helix similar to the original Caterpillar, not just forward *WSS streams like in the shield bug, centipede, and silverfish -- a forward glider stream can't catch up to the front. So someone would have to design a helix, and use it to build a front end that can build a new pair of Fx77s every 154 ticks -- and then we might be able to start figuring out how to use gliders from an Fx77 spine to generate the helix somehow, and also destroy Fx77s at the back end of the spaceship.

There's probably a clever solution out there somewhere, but it might be easier to build a specialized Caterloopillar or Speed Orthogonoid to chaperone one of these Herschel spines along, instead of working all that out.

(Anyone else have a better answer?)

I don't know why

[Schiaparelliorbust]

AFAIK, then maximum speed of a spaceship is c/2 in many rules but all spaceships that I've seen that travel at that speed travel 1 cell every 2 generations. But is it possible to have one that travels 2 cells forward in succeeding generations and then "recharge" its leading edge to length 5 or 6 in the next two generations? I'm assuming at least B3i to move forward and no B2a (because that would give lightspeed spaceships).

[toroidalet]

233P3H1V0. I think there might even be c/2 examples (where it advances 3 and falls back 1) but I'm not sure.

[Schiaparelliorbust]

Thanks! I would still like to know if there are (known) c/2 examples in CGoL or other rules. I don't see why they shouldn't be possible. I don't see any examples on the wiki.

The Wiki mentions something about the spark from a grin on the bumper page. What spark? The grin is connected, so there shouldn't be a spark.
