Re: Catagolue Discussion Thread

I'd still consider it natural, since symmetry wouldn't help with the formation of an asymmetrical object. Unfortunately we do not have a SHA-256 hash for the one-bit-modified C1 soup that produces it, so it cannot be counted as natural. why is this the definition of "natural" Because if you just sa...

I'd be surprised if this wick hasn't been found already, but it was new to me.

It's called glider_block_cycle, and features in Achim's census.

Re: Potential universal construction in 16±2 gliders

EDIT: actually, we can just make this north-westerly GPSE have a much much much longer glider trail than the south-easterly GPSE (by synthesising it earlier), so that by the time that the retrograde gliders reach the synthesis site, everything else has completed and the recipe has built a couple of...

Re: Binary slow salvos

I'm going to give a general non-technical overview of the timeline of the RCT cleanly synthesising a spider. Firstly, I'll introduce some nomenclature: epicentre : the area of interest where all of the gliders collide; parsec : the distance between the construction site of the south-easterly GPSE an...

Re: Binary slow salvos

A 3-GPSE solution would be very exciting! There's actually another potential optimisation which might be able to save a glider from the 4-GPSE RCT. Specifically, if the first northwest-bound glider collides like so: x = 685, y = 638, rule = B3/S23 8b3o2$5b2o$4bo2bo$5b2o40b2o$47b2o7$43b2o$43b2o2$6b2o...

Re: Binary slow salvos

I've found a universal set for MathAndCode's original 17-glider RCT. Specifically, we have: a 3fd pull and 4fd push, which together allow arbitrary-integer fd moves; a nondestructive glider emission reaction; a destructive block creation reaction which throws the block beyond any of the lanes used f...

Very impressive work! Your two construction lanes are the same phase and 6hd apart. Is it possible to make them 3hd apart instead?
