Re: Refactoring DRH's cyclotron with stable components?

Someone should probably just try it and see what happens. Seemed like a good opportunity to practice my Bandermath. Almost everything worked pretty much the way I expected: without rectifiers, the Snark+Bandersnatch+rephaser block toolkit isn't universal, and I don't see how to make it work to get ...

Re: Refactoring DRH's cyclotron with stable components?

I think the block is absolutely in keeping with the spirit of the original challenge. It's been known for a very long time and it is not even close to producing an excess glider. Okay, then the remaining problem involves dropping in a lot of Snarks and Bandersnatches, connecting outputs to inputs w...

Re: Refactoring DRH's cyclotron with stable components?

Any chance of optimizing https://www.conwaylife.com/forums/viewtopic.php?p=71925#p71925 further using https://conwaylife.com/wiki/Bandersnatch? Specifically, can the rectifiers be eliminated? The rectifiers were only needed to get some use out of two gliders on closely spaced output lanes. The Band...

Re: Glider-Powered Spaceships

More tomorrow, but here's a universal set of turners... I've re-arranged the numbering system, on the theory that glider adjustment toolkits more commonly work in terms of how many ticks an OTT slows down/delays a glider, rather than how much it advances the glider from some default. I think maybe ...

Neat! Now all we need to do is to assemble the timings and splitters. I've just finished some searches that can help with that. More tomorrow, but here's a universal set of turners that's a bit better than the crazy awkward set of Blockic stuff I used in the old quadratic-growth seed. EDIT: Reverse...

Re: The Hunting of the Elementary Conduits

Paul Callahan suggested this morning that the left side of the Bandersnatch might be catalyzable to get a different glider out, or possibly an accessible B, R, Herschel, or some such. I tried a couple of catgl runs. Only got this far, but catgl doesn't look for transparent blocks or beehives: x = 16...

So how do I get the script for a pattern? What is a specific example of a pattern that you want a script for? What kind of script (Python? Lua?)

Perfunctory apologies for the double post, but the last post probably needed a TL;DR already. Here's a blueprint of Type 2 spiraller circuitry.

Re: The Spirallers Question

All the tools to make a Type 2 spiraller are available, but I'm not sure Type 2 is of general interest. So far, the majority of devices that can switch a construction recipe from one loop to another have been based on one-time turners, but in this case it would be a good idea to design permanent cir...

Re: Methuselah based spaceships

First answer me this - when was the last new rake invented? Depends on what counts as a "rake". Maybe a few months ago . Maybe few weeks ago -- there's nothing terribly interesting about the rakes making up those patterns, but it might be true that nobody ever put them together in quite that exact ...

The fix you posted breaks the symmetry... Yeah, sorry, adding the block was more of a test than a suggestion. I wonder if an idea like this would be useful?

Re: Methuselah based spaceships

So the plan is: build a series of rakes moving in the same direction as the fuse burns, plus block synthesizers or whatever is needed to make *WSSes for that layer, at just the right speed to keep the wick burning without blocking the glider-output mechanism. That's sort of the general plan for bui...

Re: Glider-Powered Spaceships

I'll run a fresh search for LWSS seeds and see what turns up. It looks like well-spaced constellations (no pseudo still lifes) that fit inside 8x8 will probably offer enough variety to produce the LWSS seeds we need. Here's one that works for the two closely-spaced LWSSes at the top of the space ra...

The *WSS rakes don't even have to go as fast as the fuse burns since the *WSSes move away from the rakes... Seems like that would only be true if the helix is an orthogonal one, like the one in the Caterpillar. Otherwise the rakes building the helix-making fuse have to go perpendicular(ish) to the ...
