Re: Universal helix working notes

3. From stage 2 we also need to leave two SLs and collide them into *WSS to ignite the fuse and kill the puffer using one of these recipes: Did you perform this search with gencols? I think there might be some results missing, those where the bait spaceship has common neighbor cell(s) with the puff...

Re: Universal helix working notes

We need some trigger - like SL that converts to glider, that ignites the fuse that converts back to SL but after some distance. But a still-life will not just simply convert to a glider, you need to wreck a couple of spaceships into it. So why not just ignite the end of a fuse with a couple of spac...

Re: Universal helix working notes

Okay, thanks, I think I got the idea. Maybe I'm missing something, but is there really a need to ignite the fuse with gliders? Why not use forward *WSS to do it directly? EDIT: It's also not quite clear to me, if still-life phase is needed. Can't we adjust the speed just by delaying the moment when ...

Re: Universal helix working notes

Why synthesise blinker puffers by colliding spaceships from the helix with still-lifes? Why not just make blinker puffers part of the helix itself? (Like ping-pong.)

EDIT: I'm not sure I understood the concept. Why is it better than just making helix out of *WSS?

Re: Caterloopillar WIP (all speeds < c/4)

Well, I think we should stop being engineers at this point and become mathematicians. If there are any principal limitations for the caterloopillar design besides speed limit of c/4, they should be mentioned. Otherwise I would just assume, we've got a good enough theory how to build a spaceship of a...

This is a pretty old idea. Gabriel Nivasch even wrote an exhaustive search program for this particular purpose 16 years ago, but there's been no luck so far.

Re: Engineered Spaceships Q&A

Well, I would argue, that centipede's frontend is not a helix. I used to propose a helical frontend for a 31c/240 spaceship, but it required much more spaceships than there are in the final design.

Re: Caterloopillar WIP (all speeds < c/4)

I'm wondering how we should present these results on the status page . Obviously, this gives versatile puffers for (1,0)c/6 and (1,0)c/7, but should we add any new speeds to the list? If so, how many? I think time has come to differentiate between elementary and macro-spaceships and puffers on the ...

Essentially it is a wick, that burns at a certain speed. Some move faster than they burn, thus you can use them as frontends for macro-spaceships. I recommend an article on Caterpillar by Gabriel Nivasch.

Re: Longest lasting patterns

The point is that you can build a pattern, that eventually stabilizes after arbitrarily large number of generations, and you can mathematically prove it. So basically that's an argument about the largest integer one can think of.

Re: is this c/10 spaceship known?

Well, the problem with the loafer is that it's gonna be arguably 100% natural, even if it comes out of a symmetric soup, because it's asymmetric itself. But that also means that effectively there are more cells to occur serendipitously.
