Spaceship Eaters

Post any spaceship eaters you have constructed here.

Almost Swan eater

Here are 10 glider eaters that I have made: (These are not in Dean's collection!)

They have very long stabilisation times.


I've made a weekender eater, which uses an interesting block perturbation.

oo!
The massive eaters cannot be replaced with smaller ones -- the spark would interfere.

Converters are also quite useful. I completed a glider => Cordership converter a short while ago; you can read a commentary on Dave Greene's blog:

http://b3s23life.blogspot.com/2009/02/f ... rship.html


Less well-known is the reverse reaction, which transforms a Cordership back into a glider. I have built one that accepts Corderships with a 487-tick spacing:

Of course, an eater1 in a slightly different location can replace the eater2, reducing the bounding box, population count and construction difficulty:

A smaller and faster eater for the 2c/5 spaceship:

It can handle a p52 stream in a unique way (by eating pairs of spaceships as well as singles), or p53 and higher in the normal way.

Not impossible, certainly... at least with a liberal definition of "eater". For example, you could hook up the two Herschel outputs in the following pattern to the seven asynchronous LWSS and glider inputs, and you'd have a stable 114p6h1v0-eating pattern:

Code: Select all

This would probably be more of a converter than an eater, I suppose, since you could get any number of signals out of the thing during the cleanup stage. The pattern would take thousands of ticks to recover, but I'm not in any particular hurry -- at least until someone shows me a 114p6h1v0-gun. We still seem to be a long way from finding a construction recipe for anything that big.

Should really fire up gencols or ptbsearch to look for better base reactions in cases like this, I suppose -- but it's too much fun drawing in various catalysts by hand and then, usually, watching everything blow up.

I wouldn't be surprised if it was possible to place, say, a sacrificial block or beehive in the path of the spaceship, and add various catalysts to get a fairly clean glider or Herschel out of the resulting mess, and route that signal around to rebuild the "bait" still life and maybe shoot down one or two leftover pieces of junk. Here's a sample where you'd have to rebuild a beehive and clean up three other objects:

Code: Select all

#C 114p6h1v0 + beehive -> 2 R-pentominoes, 2 beehives and a boat
x = 20, y = 41, rule = B3/S23

Still might not be worth finishing a construction along these lines, but it'd be a big improvement over the LWSS cleanups in the blueprint above.

I had a feeling a positive result would show up, that's why I added the question mark. I know it inspires me when I am told something is impossible or can't be done.

If the definition is "eater = eat it in n tics or less" then eating a 114p6h1v0 is truly impossible for sufficiently small n. My idea of n in this case was around 100 or even 200, but I didn't specify. I like your solution.

My next question is:
How few blocks does it take to create a "one-time eater" or vanish reaction for the 114p6h1v0?

4?

I'd call that a complete eater; if the second ship is also eaten, it's just two stage. In fact, a eater like this (but for a simpler ship, like a glider or *WSS) would be a great flip flop.

There is an eater like this for the glider, which fits within a 4 * 2 bounding box. I leave it as an exercise to the reader to find it.


And it has been used as a flip flop in a binary counter, and in Dean Hickerson's Fibonacci pulse dividers.

You mean the snake? That produces its ship rather close to the snake; I was thinking something larger that makes something easier to utilize.

Boat-bits caught by snakes are surprisingly easy to make use of -- there have been at least half a dozen different mechanisms built into various patterns. Calcyman mentioned a couple, but there are other Herschel pulse dividers, and a "self-constructing" Herschel conduit, a way to catch a glider and turn it into a pi-heptomino and then a clean Herschel with another couple of following gliders, and some other non-Herschel-related reactions that can successfully test for the presence of a boat-bit.

This next part will be old hat to some people, and I may be wandering away from "something larger" into "something way too large", but here goes anyway: back in October 1996, Paul Callahan came up with a stable flip-flop circuit that produced a Herschel or glider output for every two glider inputs. Here are a couple of variants:

It's big and slow, but Spartan (easily glider-constructible). There's a third version that uses an Fx77 conduit instead of the Fx119, but it's even slower to recover.

Nowadays there are slightly faster Herschel-based flip-flops, such as

But obviously, useful stable flip-flop patterns with glider inputs are still fairly big and slow. There are lots of smaller period doublers that are periodic -- i.e., patterns including oscillators as well as still lifes. Some examples are given here (LifeNews). But I'm afraid that's getting _really_ far afield from the original subject.

EDIT Apr 2017: If anyone does a search and ends up here, there's been a lot of progress on period-doubling "flip-flops" in the past several years, starting with Guam's semisnark. See also the Stable Signal Converters thread for mechanisms that could easily be blocked off to make spaceship eaters.

Wow. This topic is dead.
I guess what happened is that spaceship eaters turned out to be a special case of spaceship converters, so most of the activity has moved to threads like this one instead.

I'm just going to post some of my eaters that I discovered completely by myself.
Nice collection! Several of these have been found by other people, too, but I don't remember that nice 56P6H1V0 bait block from anywhere else (except where you put it on Useless Discoveries yesterday).

Blocks are often rebuilt with a factory instead of by painfully synchronizing two gliders:

If we only had a synthesis for a 56P6H1V0, we could add it to the now fairly long list of interconvertable signals. But until then, I suppose it doesn't matter much if there's an output signal or not.

Thank you for the smaller eater. I don't actually know where to find factories.

They're not terribly well organized -- you just have to look through the thread to find the type you want. I gave the link above. Or links to all the major collections of circuit types will pop up when you open the h-to-h-collection ZIP file in Golly's Life/Signal-Circuitry folder.
