I suppose the start of a small spartan stable reflector would be looking for a spartan stable LOM->Block to replace 31.4
in the snark. Has anyone searched for small constellations that would do just that? I suppose that still life factories thread would be useful.
Probably it's been looked at at least to some extent. Before Mike Playle finally came up with the Snark catalyst(s), people tried all kinds of things on the following version of the Snark reaction, found by Dietrich Leithner way back at the end of the last millennium:
Code: Select all
x = 16, y = 21, rule = LifeHistory
See this post
, for example, almost nine years ago in this very thread. There are enough unfinished search branches in that one stamp collection to last a lifetime... if you wanted to be really, really thorough about hunting for Snark-reaction-based glider-to-2-glider converters.
It's definitely always possible that everyone missed something obvious, and that a CatForce search would turn up a way to catalyze a LOM to drop a block back in exactly the right place.
But the block would have to get thrown to a very lucky location. The near-complete lack of elementary conduits with LOM inputs seems to indicate that a LOM's particular kind of explosion is pretty difficult to tame with small stable catalysts... for whatever reason.
So if nobody has done that search, it's because everyone who has experience getting results out of search programs has decided that the odds of success are too low -- and so they've spent the time doing other searches that seem like they have a better chance of success. They might or might not be right in that judgment, but the only way to prove them wrong is to develop your own searching expertise and run a search like that yourself (and then actually find something.)

I just somewhat answered the first question in the other place you asked it
. C/C++ is the usual language for search programs, because it's almost an order of magnitude faster than a Python script, and nobody is too interested in finding only a tenth as much stuff as they could, for no particularly good reason.
I'd best not even try to assist with compilation issues on a Mac, since I don't have one handy to try things out on. Hopefully someone with more Mac experience will pop up eventually with some advice.
