### Re: Thread for basic questions

Blockspam is when someone creates a symmetry in Catagolue that is a whole bunch of blocks and usually nothing else; if it overtakes C1, it becomes a troll symmetry.
What you've seen before (and what you were "warned" about, not that you did anything wrong), is actually block party, not block spam — the input is a whole bunch of blocks, and they interact and can form pretty much anything.

Yes. See Chapter 9, Section 9.1.1 ("A Sliding Block Register"), or more generally sliding block memory on LifeWiki.

There seems to be an unstated assumption here, that the eater has to be a connected strict still life. Otherwise you might have preferred

Code: Select all

``````x = 61, y = 12, rule = B3/S23

(from Golly's Patterns/Still-Lifes/ss-eaters.rle). If constellations are allowed, a plain fishhook plus a honeybit would do everything that that single-piece Frankensteinian monstrosity can.

You can weld a regular fishhook onto that one-piece HWSS eater more cheaply than that eater2 variant, and it still eats lots of things:

Code: Select all

Okay, thanks! I would have preferred strict/pseudo still lifes, but that works too. I wanted the Eater 2 because it's one of the "standard" eaters.

Is there a circuit that can be toggled to change the output? So whenever it is toggled, the conduit releases a glider of a different lane/direction.

### Re: Thread for basic questions

Here is a small circuit which can have its output turned on and off, and could be combined with a splitter and some snarks to have a glider sent in another direction when the output is off. Would that work for your situation?

For the more general case where you want to cycle between N output signals, just string together a period multiplier that allows one out of every N signals to escape, make a signal splitter that produces N signals, and put a period multiplier on every output -- with each multiplier in a different phase.

For the more general case where you want to cycle between N output signals, just string together a period multiplier that allows one out of every N signals to escape, make a signal splitter that produces N signals, and put a period multiplier on every output -- with each multiplier in a different phase.
No, I mean like something simular to a permanent switch, but instead of cleanly absorbing signals and not allowing them to pass when switched, it redirects the signals.

Ah, OK. There are mechanisms that can be combined to build something that matches that description. Here's an old thread that might help, for example. I don't recall that anyone has built a modernized version of calcyman's example pattern recently, but it's not quite what you want anyway. Quite a few options show up as you read down the thread.

To wire that stuff up into an answer to your question you'd need a Herschel splitter attached to two permanent switches -- and a TOGGLE input also connected to a signal splitter, with each branch connected to one of the permanent switches' TOGGLE inputs. I think maybe two of these permanent switches would be among the simplest options we have at the moment. (?)

Yes, this adds up to a bit of a tangle, especially when you include the X-to-LWSS converters, and yes there ought to be something simpler. The above would be totally safe for all possible inputs, though, as long as considerations like repeat time don't come into play.

1) Is the beehive accepted as a 6-cell solution using this 2G synthesis?

Code: Select all

``````x = 57, y = 33, rule = LifeHistory

2) Are arbitrary constellations acceptable, or only true objects?

Edit: it seems the pentadecathlon cannot be removed with its 3G synthesis but can be turned into a block or a beehive:

There isn't any "largest object", I suspect. It should always be possible to find new objects with that property, that are bigger than whatever the current biggest known object is.

That implies doing some engineering to make silly sub-optimal recipes for objects, though, specifically so that they'll have that property. If we're not allowed to do that, then I guess we could get an answer by running every synthesis in Catagolue twice in a row, and pick the biggest one that happens to cancel itself out.

Let's see, a sample or two of these "river" patterns got discussed recently for inclusion in Golly's pattern collection.

The short summary is that rivers happen when there are two parity options for a common expanding background. Often this is some variant of a checkerboard pattern. Where the two background parities meet, there's inevitably a constant argument going on, usually a very active argument -- as each parity continually tries to propagate itself at the expense of the other parity.

I don't think it would be possible to use just a block as bait, no. It just pulls the block (2, 1) without doing much that can generate signals. If you use multiple objects there's plenty of things that can produce an output signal, then you just have to add a bunch of duplicators and reflectors that reconstruct the block plus whatever other object gets caught in the crossfire. Something like this but probably with a Herschel output, but I think there's Pi-based conduits that would work fine:

A pattern with a forward-moving mechanism which completes 1.00 or more cycles but is then overtaken by its ash. The forward moving mechanism subsequently emerges from the ash and the process repeats. Could such an object exist?

Sure, there might be some ash you could put behind a switch engine, that happens to catalyze a switch engine's self-destruction in such a way as to start a new switch engine after a while, with the same ash in the same position behind it... unlikely, for sure, especially given that we haven't seen it in Catagolue yet, but it would be mighty hard to prove that it doesn't exist.

The Speed Demonoid and Speed Orthogonoid are kind of engineered variants of this idea, with burning fuses catching up to c/4 and c/2 puffers.

Hi all,

is there a way in Catagolue to show just true oscillators, that is, oscillators having at least one cell with the object's period?

I'm investigating the rule b456s234 and it tends to produce oscillating blobs of low period connected by lines, like this thing, which consists of noninteracting regions with period 2, 5, and 9 connected by string. I'm not super interested in such objects because no cell in it actually oscillates with period 90.

And it took me a lot of sifting through boring three-by-fours to discover a 'pure' period 12. Is there a better way to do this?
