Spaceship Eaters

Someone who doesn't like ugly welds might want to fix the hideous bodge job in the northeast -- that was just to make sure that it was going to work.

EDIT by dvgrn: This pattern had no text with it, but I think it's just a copy of the last version of the converter/eater I had posted on the previous page, with a couple of things patched up that I had also patched in the meantime. Good to have it at the top of a new page, though --

As before, a following *WSS can show up as soon as 487 ticks after the first one, but the delay has to be odd if the number is between 487 and 591 inclusive -- and the output will be the same as if it had showed up 591 ticks after the first signal. Also a third *WSS can't be allowed to show up early -- have to wait an extra 591-N ticks and pay back the borrowed time.

Three ticks faster by replacing a snark with an Fx77...

Nice find! I wouldn't have expected that to work. Tightening up a Snark/syringe weld to standard form:

I've added a link to this in the first post in Stable spaceship converters. What else have I forgotten to update in that list?

I didn't have time to explain my last post because it was so late at night.

A more better rle (1 small stator reduction, moved the eater closer, removed a single dot):

And thanks to dvgrn for making me remind myself that the second pattern had a lot of state 2(lifehistory) mistakes.
(only reposted the patterns to make it more perfect than previous posts)(just like updating my eaters every so often i found a mistake or stator reductions)

Wonderful work on the universal xWSS→G converter! That naturally brings up my noob-y question: is there any M/HWSS→G converter that can tell the parity of the input? Probably we can have the input activate something with its spark, and then crash it into something like

Code: Select all

A step further, can we also tell if the input is an MWSS or an HWSS? The difference is at their sparks.

Wonderful work on the universal xWSS→G converter! That naturally brings up my noob-y question: is there any M/HWSS→G converter that can tell the parity of the input?

I don't know of one, but maybe something could be built. If we're allowed to use high-period oscillators, there's no doubt a way to test for the presence of a singleton or domino spark at a very specific spacetime location to figure out HWSS or MWSS or even LWSS parity. It's fiddly and complicated, but doable. A completely stable structure... well, no doubt that's doable too, but it would take a complete rebuild.

All you'd have to do is enumerate a big pile of constellations, and find the one that's cheapest to reconstruct, that when struck by the six possible *WSSes creates a different explosion (with at least one output glider for each explosion, on different lanes). Each output glider lane is attached to a slow-salvo shotgun that cleans up any leftover junk and rebuilds the bait. It's slow and awkward, but it should work.

A step further, can we also tell if the input is an MWSS or an HWSS? The difference is at their sparks.

I thought we had an HWSS Heisenburp mechanism, but I can't seem to find it. I did find EV2's rebuild of the stable MWSS Heisenburp. If we can find a bait for the HWSS that consists of a single cell in the adjacent lane, then the MWSS would go right by but the HWSS would trigger the Heisenburp. That's a start, though it might be necessary to use 2c/3 or lightspeed technology to get the MWSS Heisenburp mechanism out of the way, if an HWSS shows up.

Also these Heisenburps probably won't work for both parities of HWSS or MWSS, so I guess this might be another place where the Six Explosions For Six Possible *WSSes method would be a better bet.

Was going to use Extrementhusiast's HWSS Heisenburp from 2013 to extract a couple of signals to do the cleanup, but it turned out that it would have had to be rebuilt pretty thoroughly to let an HWSS-on-HWSS get through. Looks like it could use a rebuild with modern technology anyway, of course --!

EDIT: There was an even older HWSS Heisenburp, from 2011, which had a fairly Rube Goldbergian reconstruction recipe. And yet it wasn't really all that terrible... I mean, five signals is pretty bad, but they only had to be sent in the correct order, not precisely synchronized, and the whole active mechanism was on one side of the HWSS lane -- though unfortunately the output went to the other side:

[yujh]

An eater capable of peeling an outermost HWSS from some flotillae, including HWSS-on-HWSS #4. Found with CatForce.

Two variants of the reduced eater, both with repeat time 36:

Code: Select all

x = 36, y = 53, rule = B3/S23

The bottom one looks nicer.

The repeat time is 35, if I’m not mistaken.
There’s also a faster eater of HWSS on LifeWiki. https://www.conwaylife.com/w/images/0/ ... eaters.png

I love the new HWSS eater! Two copies of the standard spaceship eater also suffice for the HWSS on HWSS, although it's bulkier than the eater given above:

Code: Select all

x = 34, y = 29, rule = B3/S23

o$2b2o23bob2o$27bo4bo$28b2ob2o$29bobo$24b2o3bobo$25bo4bo$22b3o$22bo!

This gives the minimum repeat time of 18.

The third is a bit harder

The following has repeat time 885, which should be easy to beat, even with something that has a glider output (which would get rid of another red cell in that row of the table)...

46P4H1V0 eater with a 119-tick repeat time...
...
Dave's method is effective.

Not entirely -- no modern HWSS Heisenburp or 46P4H1V0-to-X yet.

Let's see if the trick works again. That other red cell in the table is now green, thanks to the following version of my 885-tick monstrosity. Now it's repeat time 1192, but it gets a glider out:

Wow! I didn't even consider trying B60 because, well, B60 never connects to anything except B60. Nice work!

What's next on your list of red table cells to turn green?
