The code I wrote to sort two-object glider-turner constellations into buckets... wasn't very well written, to say the least. In particular it got the color-changing and color-preserving 0-degree and 180-degree turners labeled backward. I finally got around to re-running the 0-degree turner analysis...

Can you do people a favor and publish this on GitHub when you have time? Thank you! Oh, I thought that I'd already published gnf2seed.py but I can't seem to find it on the forums, so here it is: import lifelib from functools import reduce sess = lifelib.load_rules('b3s23') lt = sess.lifetree(n_laye...

. p1978 (46x43) might be possible with p46 technology depending on how much of it was known at the time, but I kind of doubt it. Here's a p1978 gun that could have been built in 1978: x = 371, y = 355, rule = B3/S23 115b2o5b2o$115b2o5b2o13$54b2o5b2o$54b2o5b2o2$114b2obo3bob2o$114bo2bo3b o2bo$115b3o3...

Nice the pslmake uses 16 glider signatures (2 colors 8 phases in them) to allow filtering recipes not doable by DBCA/ECCA, unfortunately (seems to me) the database is not processed to support recipes with such restricted phases. (A lot of p2 recipes could be discarded by a pessimistic reasoning.) Y...

I'm locking this thread on the basis that it's devolved into counterproductive bickering.

Instead of letting people discuss the matter, dvgrn constantly inserts their long posts after my posts, flooding the discussion threads. dvgrn is speaking as someone who is "above the argument" even though they're directly involved as a side. This is harassment. They're trying to gain upper hand on...

... but then that particular input conduit doesn't fit. It can be connected to a Herschel transceiver: x = 92, y = 65, rule = LifeHistory 19.2A$20.A5.3B$20.A.AB.4B$21.2AB.6B$23.8B$23.9B$16.B6.9B$13.3B2A4.9B$ 12.2A2B2AB3.10B.B30.B$11.ABA21B28.3DB$11.BA3B.20B25.2BD2B$2.2A7.27B 23.B3D2B$3.A5.30B22.6B$...

At present, the name of the page is " OCA:Logarithmic replicator rule " and the replicator embed is labelled "The namesake logarithmic replicator," yet my result is shown in the section OCA:Logarithmic replicator rule#Growth_bounds . At present, for the page's title, we have three main options befo...

Firstly, since the one thing that seems to have unanimous support here (from both dvgrn and confocaloid) is having more opinions about the 'condition vs transition' issue, I'll try to explain my understanding of the difference between these two terms. (Maybe this should be cross-posted to the 'rule ...

We've finally got a new longest-lived C1 diehard, messless_14h:

Dies out on generation 1413.

21-cell form with lifespan 1410:

RT114 B-G Nice! That extensible B conduit can also yield a Herschel output by using a mechanism from the elementary conduits collection: x = 122, y = 81, rule = LifeHistory 81.2E$82.E14.2E$82.E.EB10.B2EB8.2E$83.2EB.2B7.4B7.B2E2B$85.5B6.4B8.4B $79.2E4.7B4.5B5.6B5.2E$79.E5.7B3.7B.8B.2B2.B2EB$80.3E2.7...

Good job, unfortunately I cannot see a clean line to destroy an eater Why do we need to do that, exactly? The only time that I recall that we needed to destroy an eater was in the DBCA, and that was solely to allow the elbow to 'jump back from infinity'. ... is building the white part by DBCA cheap...

Yes, I was tired to finish the adjustment (div8) ... and I wanted to code it ... here is the final/curent version: Excellent -- this can be pulled another 32fd inwards (see below). I've also swapped two of your reflectors to avoid having the hearts of two Snarks be too close together to construct: ...

Yes we can adjust the collision by 8/16 ticks not to need the eater. Wow ... 2 blocks instead of scorbie and an eater :) Excellent! Can you please incorporate this into the above design? Yep, at the edit of my previous post... That pattern doesn't work (the kickback doesn't occur because one of the...

If I calculate it well, with snark (rather to 2 eater2) and the reaction from move4 reset we could make the reflection with correct p8 synchronization ) ... so 2 blocks and eater rather to the rectifier. Yes, this works. I had to use the opposite glider phase, and also change the NW31 inserter to g...

OK, yours turn ... the final touch ... considering the build (and also the destroyal costs). Oh, you have changed the inserter to use the natural glider ... is the soluion with block and tug with tail cheaper then your original with two blocks and eater? ... I hope so. I was able to replace 3 Snark...

And a bit shrinked version: Using 3 Snarks to produce the kickback glider seems rather excessive. If we slightly rework the NW31 inserter, we can replace it with a p8 bumper together with a Boojum reflector, at the expense of only allowing the DBCA-destroying gliders to have a single phase: x = 191...

Know? x = 55, y = 56, rule = B3/S23 32bo$31bobo$30bo3b2o6b2o$19b2o9bo3bob2o4bobo$19b2o9bo3bob3o4b3o$31bob ob2o2bo4b3o6b2o$32bo4b2o4b3o7b2o$42bobo$42b2o2$29bo$29bobo$29b2o5$22b o$21bo$21b3o3$2o$bo$bobo$2bo11bo$14bobo$14b2o$11b2o$11bobo$11bo6$18b3o $18bo$19bo5$26b2o$26bobo$26bo2$39b2o$39bobo$29bo4b2o...

I have decided to sync the ecca and doing it manually would be a headache, therefore I have codded whole ecca in lua ... a dirty code with a lot of parameters I have later decided ... here is the result: Impressive! Removing the Herschels and gliders, this has a mean population of 3218, compared wi...

My intention has always been to trigger the final cleanup of the remains of the Simkin gun at the bottom with a spaceship from straight above. This was looking difficult so I implemented the available quick glider cleanup, which took a short while to set up and about a second of computer time. My s...

Locking this topic for the same reason as the original thread

The Simkin gun seeds were swapped out for seeds that were compatible with complete retraction of the off side capping eaters. The startup timing was changed to accommodate this by 72 ticks. The latter part of Pavgran's shutdown sequence was extensively reworked. The following is the shutdown: I not...

No new green things, but I did add 864 more generations: 120 more generations: x = 116, y = 86, rule = LifeSuper .3S33.O3.2O3.2O6.M3.M33.M2.M.8M.3M.M.3M$3.S32.O.O2.O4.O2.O4.4M.M10.M 21.M2.2M2.2M2.M.M4.M$2.S34.2O3.3O.O.2O6.2M2.2M7.M.M20.M.M2.M.2M.M3.2M $44.O.O11.M2.M7.2M.M4.2M15.M2.M3.2M.M.3M2.M.3M$...

Another level by trying a bit harder And one more level beyond that (to 17^^^3) by plagiarising one of the earlier diehards: x = 116, y = 86, rule = B3/S23 9b3o25bo3b2o3b2o6bo3bo33bo2bob8ob3obob3o$11bo24bobo2bo4bo2bo4b4obo6b2o 24bo2b2o2b2o2bobo4bo$10bo26b2o3b3obob2o6b2o2b2o4b3o23bobo2bob2obo3b2o$ 4...

No lifespan improvements yet, but it can be shrunk to 111x87 Further SAT-solving reduces it to 110x86: x = 110, y = 86, rule = B3/S23 3b3o25bo3b2o3b2o6bo3bo33bo2bob8ob3obob3o$5bo24bobo2bo4bo2bo4b4obo6b2o 24bo2b2o2b2o2bobo4bo$4bo26b2o3b3obob2o6b2o2b2o4b3o23bobo2bob2obo3b2o$ 38bobo11bo2bo6b2obo5b2o15...
