Synthesising Oscillators

[dvgrn]

This may not be the best place to ask this, but is there any sort of collection of synthesis components?

There was one on Pentadecathlon, before it went down, but Koenig may still have the files.

I didn't hear any rumors about the reason for pentadecathlon.com's recent downtime. Koenig maintains a large amount of server-side code that generates all those pages from his databases. It's all hosted on his own server, and sometimes a move or a hardware failure or an OS upgrade will cause temporary interruptions.

But rumors of the site's demise are a bit premature. Most of the Glider Construction pages seem to be responding pretty well this evening, anyway.

Unfortunately, the Component Catalog page appears to be empty.

Nice!
By replacing the block with a glider, there is also no debris, for a net saving of two gliders:

But why not save two more by eliminating the pi entirely?

(I haven't checked the 18-cell still-life syntheses, so I'm not sure if there is a better way to make the base still-life)

[gmc_nxtman]

If there is a component that works here, then we might have a synthesis for a p16 billiard table:

[Bullet51]

If there is a component that works here, then we might have a synthesis for a p16 billiard table.

Much more promising than this one:

Actually, they are different billiard tables... This would arguably be easier to invoke the p16 you are describing. (Edited the pattern)

Although I'm pretty sure there are other solutions along these lines.

One of the objects on my to-do list has been a griddle w/siamese integral w/hook (and similar objects), for which I have long had a synthesis that comes close, but doesn't quite work. A recent apgsearch find of a related object prompted me to search Catagolue, and while none of the syntheses there seemed practical, one did have a promising immediate predecessor. Here are a few partial attempts to synthesize this predecessor. As a bonus, since this grows the griddle from a claw, it also works with other claw-like still-lifes. In particular, it could make the griddle on cis-snake much more cheaply:

There are other 3 glider collisions that (almost) produce the necessary spark but I couldn't clean any of them up in less than 2 gliders. Maybe someone else can do better.

Excellent, thanks!

There are other 3 glider collisions that (almost) produce the necessary spark but I couldn't clean any of them up in less than 2 gliders. Maybe someone else can do better.

I know a lot of 3-glider collisions that make a "J" spark, but all of them with the stem part facing foward, which is not useful here. I found a few ways to make it the right way, but none that would't also attack the inducting curl.

Synthesis of a little unix-based p6: ...

This can be done with 13 gliders, saving one glider.

This is based on a small six-glider block to unix component: ...

This can be done with 5 gliders.

Also, this makes for two 12-glider syntheses of double unices: ...

These can be done with 8 gliders.

See the syntheses (and others) here: http://codercontest.com/mniemiec/p6.htm#p6-lg

You can continue left synthesis: ...

There are several other multi-unix variants (including Unicycle, which is slightly trickier) on the above page.

Synthesis of a little unix-based p6.... This is based on a small six-glider block to unix component.

This is a known mechanism, and it can often be improved by using a 3-glider synthesis of the long barge (see Mark Niemiec's site here).

I haven't yet developed the general case of putting blocks onto a surface, but it would likely be based off of this moving wick:

Code: Select all

x = 2, y = 10, rule = B3/S23:T0,10
o$2o$o$2o$o$2o$o$2o$o$2o!


The only thing that I've seen generate anything close to it (so far) is this soup:

Code: Select all

x = 17, y = 10, rule = B3/S23:T0,10
o2b2obo2b2obob2o$2o7b2ob5o$9bo2bob3o$obo2bobobo3bo$o3bo2bo2b7o$3ob3o3b
2o2b2o$3b4o3bo2bo2bo$bob2obob2o2b2o$o4b2o3b3o2bo$5bobobob2obobo!


(I find that T0,10 offers a good balance between everything going linear and requiring a large number of tries for it to go linear just once.)

[mniemiec]

Extrude one layer of blocks from another: ...[/code]

Excellent! I have been thinking about ways of growing a 3xN array of blocks for some time, but with no success (or even anything close). The 3x3 case allows synthesis of the the first pseudo-still-life ever found that can be broken into more than 2 distinct partitions, but not 2 (i.e. replace the 4 corner blocks with rotationally-symmetrical tables).

All missing steps are standard boilerplate, and can probably be found by looking up small portions (like block on table).

One can also combine two steps, although it's significantly more complex:
