Oscillator Discussion Thread

EDIT: The rotor splits at around row 14, maybe keeping it split would yield a completion? The fallback isn't very good though.

Well that's pretty good clearance to me.
I think you can make another search with a p1 center (or an empty center to make it split) and widen the rotor sideways to have more search space.

The reaction is somewhat picky about the blocks (or whatever would replace them).

Did you run bellman already? Just to prevent people from wasting CPU time.

That could also be a nice I-conduit if the blocks could be replaced by a permanent catalyst.

(EDIT) I believe the block restoration reaction this support accomplishes is the exact same one, or at least quite similar to the one, used to stabilize the p80 pi shuttle, but since this engine is dependent on the partial block deletion happening at p40 I don't think the two can't be used to stabilize each other.

[Sokwe]

how do I do Sokwe's fancy branching stuff?

Branching searches are probably more art than science. I only really perform such searches when I'm trying to find something for a very specific purpose (e.g., the p28 gun or the c/5 greystretcher corner). They are also easier to do with WLS than JLS, since WLS allows you to back up through the search tree and skip non-viable parts of the search space.

The way I do it, I set up the search essentially as normal, but I change two things. First, I cut a small hole in the 2-row stator buffer using don't-care cells where I want a potential branch to be. Second, I reduce the rotor width behind the hole so that any results that get very far will be thin after the branch point and hopefully easier to solve. So if I'm starting from just a spark, my setup might look something like this:

setup.png (22.96 KiB) Viewed 83675 times

So I ran this, and to my surprise it found this partial result pretty quickly:

partial-with-branch.png (25.4 KiB) Viewed 83675 times

Notice that the symmetric rotor becomes hebdarole, so we're already done with the central branch. I then save the state of the search so I can experiment with the incomplete asymmetric branch. After saving the search, I copy the current state, transpose it, and remove the cells around the branch point to setup the search. The setup might look like this:

branch-setup.png (34.56 KiB) Viewed 83675 times

Unfortunately, this doesn't find anything. In fact, I couldn't find any viable-looking partial results for this branch with a rotor width up to 7. Even if I had found something, it would have had terrible clearance. So at this point I would reload the partial result that I saved earlier and use the backup feature to back the search up to the point where the branching occurred. I can then continue the search to get new partial results.

In your case, you already have some high-clearance partial results. You might want to start with a long partial result so that you can branch much farther away from the spark.

I have attached a zip file with the .wdf files (WLS saved states) for the search states in the images shown above.

Shall we name it big mold?

Eh, sure, but it doesn't provide any of mold's sparks that make it useful, and "big mold" is probably too general of a term to apply to what appears to be a terrible-clearance thumb sparker.

This is the first I could find; There might be a narrower one (width less than 38)
Top has better clearance; Bottom has 1 fewer cell.

what appears to be a terrible-clearance thumb sparker.

Haha I think the sparker is optimized for leftwards clearance. I am not sure if it was searched out of necessity though.
