This one looks narrower than the others, which means that it can fit through narrower spaces. Is there any change that you could remove another switch engine and figure out a way to stabilize that side? Based on how little our knowledge of small Corderships was only at the beginning of this month, it certainly seems possible that there's a narrow two-engine Cordership waiting to be discovered.

I wonder whether or not it's possible to have two switch engines with one either directly behind or behind and somewhat to the side of the other that don't leave any debris, creating a two-engine Cordership that could fit through narrower gaps than the one that has already been discovered.
Marine has a non-centered Moore neighborhood and at least one gun with a very high period (11,843).

It's not impossible, but it would be a very lucky find, because the two-engine Cordership search space has already been covered -- not comprehensively by any means, but a lot of the likely options were tried by A for awesome (script here).

Theories about hypothetical narrow Corderships generally fall into the category of pattern vaporware known as "hand-waving" -- until you actually come up with a working pattern! You'll get a lot more interest if you can modify AforAmpere's search script somehow and use it to find a new 2-engine Cordership.

Otherwise... there are some technical reasons why Corderships become progressively less likely to exist as they have to fit in a narrower width. Again, not saying another 2-engine Cordership is impossible -- it's just, well, we all already have no shortage of hypothetical wild gooses to chase, and for the most part we're already chasing our favorite ones.

In other words, other people's wild theories won't usually distract anyone from spending time working on their own wild theories.

Did the search include one switch engine being directly behind the other? If not, I might do a manual search of that.

Yes but wwei23 appears to already be interested in finding small Corderships.

Edit: Here's a promising partial.

Code: Select all

``````x = 20, y = 31, rule = B3/S23
2bo\$2ob2o\$2ob2o\$2o\$2b2obo\$3bo2bo\$3bo2bo\$4b2o12b2o\$18b2o4\$2b3o\$13bo\$2bobo7bobo\$3bo7b2ob2o\$4bo6b2ob2o\$4b2o4b3o\$bob2obo3b3o3bo\$b4ob2o2b3o4bo\$2b5o4b2o5bo\$4b2o5b3o\$12b2o\$13b2o3\$13bo\$6b2o4b3o\$6b2o3bo3bo\$15b2o\$14b2o!``````
It works if one manually replaces the blinker with a block (At least two positions work.) every 48 generations, which means that it's a spaceship in ContrivedLife (although technically everything is), but it shows promise that delaying the second switch engine by a few generations or so relative to the first one would result in a spaceship in ConwayLife.

Another edit: Here's a slightly less promising partial.

Code: Select all

``````x = 38, y = 44, rule = B3/S23

Third edit: Here's a third partial that is similar to the first in the sense that it only lacks a way to turn a blinker into a block.

Yes but wwei23 appears to already be interested in finding small Corderships.

It's not small corderships in particular. It's just that the big ones don't seem have any novel mechanisms compared to the small ones, as far as I know.

I don't think anyone had even succeeded in making anything by overlapping two 2-engine Corderships.
Technically speaking, they were made by overlapping the halves of 4-engine corderships, though one was made from overlapping two block puffers.

As for 2-engine corderships, I have no idea. I've done an in-depth analysis of some of the 4-engine corderships, and they all involve debris canceling out through intermediate small internal objects (so basically everything except the blocks on the outside), but the 2-engine cordership has none, just direct cancelation.
EDIT: Fixed broken quote tag
Edit 2: Removed extra linebreaks.
Edit 3: There's a reason why I haven't been able to make a 3-engine version of my P192 cordership. It's because of the super intricate reaction in the middle that occurs instead of the usual cancelation reaction in other corderships.
Edit 4: Here's a quick explanation of what I did. There doesn't seem to be a wick in jslife that perfectly describes what I've done here, but this one is the best I could find.
If a 4-engine cordership is this,

What do you think about my partials? I haven't found an actual narrow Cordership yet, but I was nowhere near thorough.

Edit 5: I see what's going on now.
A switch engine's exhaust is composed of a blinker, and a B-heptomino. You have done a great job of removing the B-heptomino with that other switch engine, that was brilliant and I likely would have never thought to do that. However, what you're missing is a way to delete the blinker. If you let the B-heptomino evolve enough, it will make a Herschel like usual, but will also turn the blinker into a block, and this block will be out of the way of the front of the partial/ship. Now, you will have to find a similar way to cancel the Herschel with the back switch engine, and then figure out how to cancel out its exhaust. I suspect that it may be possible to use the blocks from the front engine, but I have no idea. In the end, there may be no way to do this. Don't give up hope yet.

I think that I have an idea of another way to do this. The switch engine produces several sparks, such as this one:

Code: Select all

``````x = 20, y = 20, rule = LifeHistory
14.2D2\$13.D3.D\$18.D\$19.D\$2.D\$D\$D2\$2.D\$3.D\$4.D2\$10.D\$8.D5.A.A\$8.D4.A\$14.A2.A\$10.D5.3A\$11.D\$12.D!
#C [[ T 16 PAUSE 0.5 T 64 PAUSE 0.5 T 112 PAUSE 0.5 ]]``````
Because it's sent out to the side of the switch engine's immediate path instead of in front of it, it might be useful for deleting the Herschel.

Unfortunately, it's unlikely that we'll get a spaceship out of this instead of just puffers, but trying can't hurt.
Marine has a non-centered Moore neighborhood and at least one gun with a very high period (11,843).
I'm in the process of reducing the glider cost of universal construction.

Theoretically, it doesn't have to line up with the first switch engine, but I think that we should examine all of those possibilities first because if the amalgamation is replaced with its glide reflection every 48 generations, then it only has to rely on one mechanism for stability instead of relying on two different mechanisms both working.
I tried a few possibilities with the two switch engines lined up and didn't find anything that worked, but I'm sure that I wasn't completely thorough. This might be better done with automation, i.e. a computer search.

Edit: Speaking of glide-reflective stabilizations of switch engines, this keeps both of its switch engines for over 1,000 generations, so it's probably stabilizable.

Code: Select all

``````x = 41, y = 31, rule = B3/S23
29bo\$12b3o8bo5bo\$11bo3bo6bo7bo\$12b2o9b4o2b2o\$14b2ob2o9b3o\$16b2o11bobo\$30bo8b2o\$30bo8b2o5\$b3o\$o3bo\$b2o\$3b2ob2o\$5b2o2\$19b2o\$19b2o10\$8b2o\$8b2o!``````
Of course, lots of switch engine stabilizations exist, but there are many different possibilities for the relative placement and timing, so maybe this particular setup has not been investigated yet.

### Re: Thread for your unsure discoveries

Here are a few things that should probably be mentioned as prior art, so that everybody knows they're possible and nobody reinvents any wheels.

First is David Bell's individual-switch-engine technology. It probably doesn't make sense to invent things that require two gliders per cycle to support a switch engine, since there are known ways to do that with just one sideways glider per cycle.

This improbable old reaction from Golly's Patterns/Miscellaneous/Cambrian-Explosion.rle also comes to mind, though maybe it isn't really particularly relevant:

The Cordership in the middle appears to rely on the gliders (although I thought that glider Heisenburgs are impossible). If I actually messed something else up, so the middle spaceship works by itself and does not have glider Heisenburgs, then the middle spaceship (or a shortened version) is exactly what I was looking for.
Marine has a non-centered Moore neighborhood and at least one gun with a very high period (11,843).
I'm in the process of reducing the glider cost of universal construction.

This also demonstrates one of my favorite ways of cleaning up debris: Hitting it head-on with a 2-engine cordership. It's actually surprisingly effective!

I agree that a computer search would help. However, you can't just blindly place two switch engines, you might need an extra bit of debris to get it going. For example, removing everything in a 2-engine cordership except for the switch engines will not get you a 2-engine cordership. However, an extra block in just the right place will do the trick.

The Cordership in the middle appears to rely on the gliders (although I thought that glider Heisenburgs are impossible).
Nope, you're right about the Cordership thing in the middle, but not so much about glider Heisenburps. The thing that's impossible is stable glider Heisenburps. Spaceships like MWSSes or HWSSes have sparks that can activate some stable thing off to the side, without damaging the *WSS. Gliders don't have any side sparks at all, so a glider that starts up a signal in any kind of circuitry is pretty much bound to get destroyed in the process. It may get re-created later, but that's another kind of mechanism (called a "pseudo-Heisenburp").

That switch engine in the middle is p96, so it's just as much okay for it to Heisenburp a glider (or is the glider Heisenburping it? Mutual Heisenburpification, I guess) as for any of the classic Heisenburp mechanisms to do their work without ever touching the glider. See for example the four patterns in Golly's Patterns/Life/Signal-Circuitry that start with "heisen". Except for MikeP's "Heisenblinker", there's always a complete ring of OFF cells all the way around the glider that gets Heisenburped.

The more possibilities, the less feasible a manual search becomes. I'd probably have the computer place random 12×12 soups behind the switch engines instead of putting a block in a random position, but your method will likely have the same effect.

### Re: Thread for your unsure discoveries

@MathAndCode: I'm currently running an apgsearch of two switch engiens and a block, after discovering a bug in the previous implementation that put switch engines twice as far apart as they were supposed to be, although I also had to make the program move the switch engines apart a bit since it was placing them literally on top of each other way too often.
EDIT: Partial stabilized into a 10-engine cordership (for real this time):

Marine has a non-centered Moore neighborhood and at least one gun with a very high period (11,843).
I'm in the process of reducing the glider cost of universal construction.

One good way to find decent edgeshooter reactions for various objects is to fire up slmake and build a target pattern with a high-bit-count still life restricting the options, just like the above example. 32 bits or more I think is the current safe limit, where slsparse knows that the object is to be treated as an obstacle and not as something to try to build. Either

should work, I think.

Different degrees of edgeshooterability are possible with different objects, but most good cheap edge-shooting reactions are probably in slsparse's huge database somewhere.

The main reason that I figured that it might not be known is that this would be most useful in unidirectional glider syntheses, which would typically be done by a computer, and most would likely be too long for humans to bother looking through the individual steps. I was sure that at least one computer had come up with it, but I was unsure whether or not any people actually knew about it.
The method uses the same c/2 forward movement mechanism as the B heptomino. (A B heptomino is visible at generation 25, but it soon interacts with the ash behind it.) Like the B heptomino, the c/2 forward movement is unstable (in that particular case) and decays, but while the B-heptomino's decay forms a Herschel, this instance decays into a block. There are probably other instances that can edgeshoot different common objects, maybe even a traffic light.

Edit: I tried looking for other similar mechanisms by putting random soups behind a B heptomino. Here's one example:

Code: Select all

``````x = 6, y = 6, rule = B3/S23
bo\$3bo\$o2b2o\$b2ob2o\$2ob2o\$b3o\$2bo!``````
In this case, the initial c/2 movement mechanism didn't last very long, but other pops up from generation 193 to generation 207, which then fluctuates between c/2, c/3, and possible 2c/5 or something else more complicated until generation 239 except from a brief hiccup around generation 217. (There's also an unstable c/4 forward movement mechanism from generation 102 to generation 110.) (None of these should be particularly surprising, but it's interesting that unstable forward movement mechanisms are fairly common.)

By the way, the reason that I was crashing honey farms into other objects was because when I read this, I noticed that the long boat predecessor was half of a honey farm predecessor, so I wondered whether or not a long boat could form if a honey farm predecessor crashed into an object that then destroyed about half of said honey farm predecessor, similarly to how a half-bakery commonly forms when a bakery predecessor hits some other object that then destroys half of said bakery predecessor. The northeast part of the pattern that I posted has three long boats at generation 1421 (as well as a pattern that would probably be a long boat or a very long boat if the junk that formed it had gone away from it after forming it), but none of those three were formed that way: The two long boats in the far northeast were formed from the same six-cell predecessor but not as a result of a honey farm predecessor crashing into something, and the long boat that was more east than northeast formed from a blinker predecessor interacting with a barge. (Also, a half-bakery forms at generation 359 from a corrupted bakery predecessor, but instead of the bakery predecessor hitting something then becoming corrupted, it was simply formed corrupted from a double corrupted ∏ sequence.

Code: Select all

``````x = 6, y = 7, rule = DoubleB3S23
.A\$3.C\$A.B2C\$.2C.2C\$2C.2C\$.3C\$2.C!``````
The only real lesson from this paragraph is that the pattern that I posted develops interesting patterns, which is definitely true (such as the queen bee beginning shortly after generation 1250), but that's true for virtually all patterns that last for long enough. I only tracked this pattern to about generation 1500, but I'm sure that it spawns more interesting patterns before it settles. (At generation 1426, the eastern longboat is destroyed by a c/2 movement mechanism (which originated from another corrupted ∏ sequence) that looks like it would have either died or transitioned to c/3 just before hitting the long boat.)

Various edits: I got a traffic light.

Code: Select all

``````x = 6, y = 5, rule = B3/S23
3b3o\$o3b2o\$bob2o\$b3o\$2bo!``````
A c/2 movement mechanism starts at generation 17 and lasts until generation 45, after which it starts to fluctuate between c/2 and c/3 but ends at generation 50. It ends up placing a blinker fairly far off.

Code: Select all

``````x = 6, y = 6, rule = B3/S23
o4bo\$bo3bo\$2o2b2o\$bob2o\$b3o\$2bo!``````
This one births a century fairly far off. (Normally, I wouldn't record something so messy, but centuries are common enough that there are already century converters and other century-handling circuitry.) The century itself develops a corrupted ∏ sequence that develops a c/2 movement mechanism at generation 126 (53 century time) and lasts until generation 138 (65 century time), after which it moves between c/2 and c/3 until generation 144 (71 century time). After a brief hiccup, it has another period of c/2 forwards movement from generation 152 (79 century time) to generation 158 (85 century time) and then dissipates soon afterwards.
The weekender's forward movement mechanism appears just after generation 680.

The western movement starting on generation 409 looks like it might be useful.
This one isn't optimal, but I haven't found anything better that places a beehive yet.

This one backtracks a little at the end but is still fairly good considering that the tub is less common than the other patterns that I've edgeshot so far.

``````x = 6, y = 8, rule = B3/S23
2bo\$ob3o\$b3o\$b3obo2\$bob2o\$b3o\$2bo!``````
Less than a minute later, I have found another B-based edgeshooting of a tub, although this one later destroys the tub.

``````x = 6, y = 8, rule = B3/S23
b2ob2o\$o2b2o\$2bo\$4b2o2\$bob2o\$b3o\$2bo!``````
By the way, if someone figures out how to make tubs with period 84 or 168, this could be made into an oscillator. Maybe we can edgeshoot the tub…
This one edgeshoots a blinker in the initial direction of movement.

Code: Select all

``````x = 5, y = 8, rule = B3/S23

This edgeshooting has increased distance at the cost of increased messiness.

Code: Select all

``````x = 6, y = 8, rule = B3/S23
3b2o\$o4bo\$bobobo\$ob2o2\$bob2o\$b3o\$2bo!``````
This is even more exaggerated than the previous one: It's amazingly directional but very messy.

``````x = 6, y = 8, rule = B3/S23

Why have I edgeshot three tubs (although two were later destroyed) but no loaves or boats, each of which is more common?

Why do I not get boats shot out far with good clearance?

This one somewhat edgeshoots backwards (and mostly diagonally).

I shall end (at least for now) with a good edgeshooting of a boat.

Marine has a non-centered Moore neighborhood and at least one gun with a very high period (11,843).
I'm in the process of reducing the glider cost of universal construction.

### Re: Thread for your unsure discoveries

I wonder if this diagonally-symmetric explosion can improve the syntheses of a few diagonally-symmetric objects:
