Synthesising Oscillators

[mniemiec]

Short key and skewed pole reduced from 33 to 13 gliders via soup:

The add-anvil converter can also grab onto unstable hinges just as boat-bits can,
which gives a few additional cheap still-life-on-anvil sytheses.
(I only did this with the 2-3 glider bases; I'll leave the 4+ glider ones to someone who has more time and better tools).

EDIT: Trans skewed poles reduced from 20 to 18, from a soup, and then to 14 from another soup:

I did that (in the sense that I also added it to Shinjuku) in 12 some days ago:

Code: Select all

x = 36, y = 40, rule = B3/S23

3bo$22bobo$8bo$8b2o$7bobo18b2o$27b2o$29bo2$b2o$obo$2bo!

Also, capped AK-94 in 58 gliders by reducing the cost of the Bellman 1 catalyst by two (and skipping the add-boat step). I believe that this oscillator is the smallest known for its period (non-trivial, of course):

Code: Select all

Obviously, this means the one-barrelled AK-94 is doable in 52:

On Sunday, I concocted this Rube-Goldberg converter to edge-shoot a hook-with-tail tines-first. I'm not sure how useful it will turn out to be. (I originally experimented with this years ago, without success, trying to build the trans 16-bit pseudo-still-lifes with two of these touching, but this particular mechanism isn't suitable for either the cis- or trans- form). It did solve 3 of the unsolved 19-bit quasi-still-lives. I'm sure the 7-glider pre-block from above or the 5-glider spark from the left can probably be greatly improved:

EDIT: A couple of (unfortunately, fairly useless) attempts to make edgy caterers, based on soups. I was hoping to eliminate some of the unsynthesized carerer-pairs by using these back to back; unfortunately, in each case, the active area forms a domino shifted one cell sideways one cycle before being in the correct place, so the only way this wouldn't be intrusive is if two of them induct each other along a line of symmetry.

This is theoretically possible with the bottom mechanism; unfortunately, I haven't been able to find a way to get two of them back to back without incoming gliders interfering with each other. (It's basically lom+traffic-light+blinker; making the lom from block+loaf seems best for not crossing the line of induction).

This came about when debugging Shinjuku's behaviour when predding oscillators – it turned out to be an indentation error. The very first soup I examined gave the syntheses above.

Other lightbulb variants should be easily derivable from the above base, including the snake version.

Yes, this does also improve syntheses of all the other derived lightbulbs I have. Curiously, moving the glider right one space flips the bookend, and two of them make the house:

Edgy (am I using this term correctly?) 5G figure eight, found once again using synthesise-constellation: ... Improves the following syntheses: ...

Nice! The most common syntheses of figure 8 all seem to develop the same way - two gliders hitting a teardrop. The trick is to make the teardrop as unobtrusively as possible, but they all have the same problem - that the figure 8 slides sideways into place, making this method unsuitable in some situations. Here are syntheses for 6 other objects and 5 pseudo-objects that I have that are also improved by your new synthesis.

Another way to make figure 8 is from 2 solid 3x3 blocks; I found an 8-glider synthesis that slides the figure 8 in from the other direction, making the cis version of rattlesnake and figure 8 possible.

EDIT: The above syntheses for figure 8 and octagon 2, and the last two boat on pentadecathlon and figure 8 only tie the records, rather than beating them. I also forgot three others:
