Weird replicator that sort of hovers on the edge of Class U and Class D: x = 5, y = 5, rule = B2k3aci4aiqz5e6ce78/S2aek3cijqr4aceint5kn6ak 2o$o$2o$2bobo$2b3o!

Putting two p392 ships together so their side-sparks eventually produces a p1176 ship: x = 137, y = 41, rule = B2k3acijr4ijqy6i7c/S2aek3ijnqr4it5n 2bo$b3o$2o2bo$o2b2o$o3$134bo$133b3o$132bo2b2o$132b2o2bo$32bo103bo$31bo bob3o$31bo2bo2bo$30b2ob2o2bo$8bo22b6o$5b3o$4bobo2b2o$3bobob2obo93bo$2b 2o3bo91b3ob...

The latter one should be known, given its size.

Yeah, it's the fourth RLE in dani's OP.

It's most likely that /attribute can't find the discoverer because the haul in which it was discovered has already been auto-deleted - this is quite possible, as carybe was (up until a few hours ago) submitting hauls fast enough they get auto-deleted in less than 12 hours. This also means it is extr...

This is an intrinsically unbalanced challenge, because B35/S135 is a totalistic rule and thus gets numerous built-in speedups that B36i/S234j does not. As a result, there is a wide difference in the searching speeds: on my computer, the former runs 30k soups/sec/core and the latter 700.

Lifelib can handle arbitrary neighbourhoods and combines with apgsearch, though apgsearch requires the neighbourhood to have at least rotate4 symmetry.

It's based on the crawler in this thread, which is indeed about the concept of a 28c/88 caterpillar.

I have an NVIDIA GPU, but macOS 10.12.6 instead of 10.13. However, I do occasionally get the option to upgrade to Mojave (10.14), so that means my hardware should be able to support it - I just haven't decided whether upgrading to 10.14 is worth it (I used to have a Windows computer, and when I upgr...

Nathaniel described such a proof in 2009, and apparently John Conway proved it almost immediately after CGoL was invented: http://www.njohnston.ca/2009/10/spacesh ... -automata/

This "traffic" is actually a very efficient method of freeze-drying (used in CGoL's caterloopillars), right?

When I try to run --cuda, I get this error:

I take it this means I need to download/install something called nvcc?

I've modified the backout process to readjust numsoups and numobjects, and backed SAD's haul out of the census. Now Snowflakes is below the 10^12 mark, it's returned to accepting hauls without running Parmenides (the combination of statistical tests, object validity checks, and peer verification). ...

The troll haul also pushed Snowflakes past the 1 trillion objects threshold to require verification, and it appears Snowflakes verification isn't working very well, throwing a rather large number of hauls into the red zone (?committed=4): http://catagolue.appspot.com/haul/b2ci3ai4c8s02ae3eijkq4iz5ar...

Not directly, but I think you could apgsearch alternating rules indirectly by generating ruletables for them and then apgsearching those ruletable rules via lifelib.

Okay, whoever added this spam haul to the census (they did it anonymously), it's not funny.
