Immediate further improvement:
I played around with the result and found a few slow components. They may or may not be known.

Code: Select all

``````x = 180, y = 30, rule = B3/S23

I also found a partial that I couldn't figure out how to stabilize.

Code: Select all

``````x = 22, y = 29, rule = B3/S23
15bo\$13bobo\$14b2o2\$18bo\$18bobo\$18b2o3\$2b2o\$bo2bo\$b2obo\$4b3o\$b2o4bo11b

By the way, do you want the base that I told you about?

Edit: Unrelatedly, here's a modification of the xs25_39u0o4czw12ldzw65 synthesis that I made a while back:

Code: Select all

``````x = 41, y = 44, rule = B3/S23

I think that there are one or two other syntheses that can be modified in the same way.

Is it possible to complete this synthesis of xs22_255m88gz8kkd221 using 2G or 3G collision?
This synthesis is needed to reduce glider cost of the Turtle.

It's probably possible to edgeshoot that loaf predecessor or a similar one in a compatible way. I'll look at the loaf syntheses.

Edit: I found a suitable three-glider collision.

Another edit: There's an applicable fast component (although it probably isn't relevant to the turtle synthesis).

Code: Select all

``````x = 35, y = 38, rule = B3/S23

I'm posting this here in case someone can find a good cleanup for it. (May13 seems to have a knack for that sort of thing.)

I have historically worked on conduits, but recently, I've been working on glider syntheses and investigating SnakeLife.

It often surprises me how few gliders are needed to tame an ugly-looking explosion. This reaction might be a good excuse for someone to finally write an efficient exhaustive enumerator for two-glider cleanups -- maybe lifelib-based?

If the enumeration could be ordered by the gliders' collision times, so that all early-collision options are tried first... then a lot of two-glider cleanup problems could be solved by a "run the search until you're bored" method. If there's a solution out there to be found, 99% of the time it will show up before the searcher's patience runs out. The search might not complete an exhaustive enumeration in any reasonable amount of time, but it wouldn't really make sense to check all the really unlikely options toward the end of the enumeration anyway.

-- I guess gencols could find a two-glider solution eventually, but it seems like that would need an awful lot of setup. Something more convenient is needed. A 2G cleanup is the only way to improve on this:

Code: Select all

``````x = 133, y = 62, rule = LifeHistory

Is this known?

EDIT: It's a 1G seed for a bun on block and snake.
For some reason this older post caught my eye. It looks like an equivalent-cost synthesis is known: the current-best synthesis for xs17_mm0e96z56 is 7 gliders, also using a 5G conversion of a beehive.

Code: Select all

``````x = 50, y = 20, rule = B3/S23

bo\$42bo3\$48bo\$47b2o\$47bobo\$40bo\$40b2o\$39bobo\$47bo\$46b2o\$46bobo!``````
And the same conversion is used for xs18_mm0e952z56, not surprisingly.

I went ahead and boxed wwei47's equivalent converter for a random larger object, on the theory that it's a nice variant and would make it possible to build Spartan seeds for a number of fairly complicated-looking objects. The known 5G converter is all-at-once, but this variant is basically a three-stage converter -- would be really good for slow-salvo constructions of things. Not that we need to add block-on-snake to anything that I know of, but still... maybe someday?
