Agar stabilization discussion

Post by Sokwe » April 18th, 2010, 4:14 am

This topic is for the discussion of periodic agar stabilizations. A typical post would include a new agar that might be tamable, a new partial or complete stabilization of an agar, or discussion of methods for stabilizing agars.

Generally, agars that react loosely at the edges have the most potential for stabilization. "Reacting loosely at the edges" is not well defined, but it is sometimes clear when an agar is not tamable with current technology. An example of an agar that probably could not be tamed with current methods is the following p27 agar:

I've attached a zip file with several agars that look like they might be tamable.

@Mike P.
Do you think your catalyst/drifter search program might be able to stabilize any of these agars?

The period-47 can be stabilized by four glider streams and a specialized eater:

A single period-61 engine can be stabilized by eight glider streams and a glider-to-block converter found by Paul Callahan:

Nicolay Beluchenko found one of the period-43 agars, and noticed that a single engine could be partially stabilized by an eater:

Code: Select all

x = 27, y = 44, rule = B3/S23
22b2o$22bo$20bobo$20b2o9$16bo$15b3o2$16b2o$15b3o8$o2bo$2ob2o$2obo3$23b
ob2o$22b2ob2o$23bo2bo8$9b3o$9b2o2$9b3o$10bo!
Part of the period-10 agar can be stabilized by two eaters and two v-shaped sparks. The sparks could be supplied at p5, but there is no sufficient sparker known, and due to the proximity of the sparks, it would probably be hard to find one.

Code: Select all

x = 14, y = 21, rule = B3/S23

It's not impossible. The accept/reject criteria would need to be changed a bit though.

Hopefully one day soon I'll get enough spare time to clean this up & put it on the net so that others can have a play with it. Spare time is unfortunately in rather short supply at the moment, though. :(

This is especially nice, because using a different period-6 sparker allows the agar to be extended arbitrarily:

Also, a portion of the period-43 agar found by Nicolay Beluchenko can be stabilized by four glider streams (which works similarly to a block-eating reaction found by Nicolay):
