Re: Spaceship Discussion Thread

clearance But isn't that variant nonspartan? Definitely non-Spartan. No doubt slow-salvo recipes could be found for it if someone wanted to try, but it's much simpler just to design self-constructing circuitry so that the extra clearance isn't needed. You can still get in trouble with slsparse if y...

Re: Spaceship Discussion Thread

Glide-reflection forces the input and output lanes to be 1hd apart, so I have to use a highway robber or some other kind of reflector with a transparent lane right next to its input lane. In other words, it can be on both sides of the input, as long as it doesn't block the output. But these inputs ...

Re: Binary slow salvos

One could send pairs of gliders. However, this has several problems, such as not being able to tell which reflection ash is present and requiring a mechanism to store how long the previous glider took to return in order to know how long to wait for the current glider. Another possibility is to ente...

Do they also work with the debris from signal reflection? No. I don't think that can be predicted in advance, even.

Re: Speed Demonoid

I've discovered a flaw in the current design. Due to the Snark being behind the still-burning second wick, you have to add delay to the loop proportional to the distance between the Snark and the splitter. So, the supremum of the speeds achieveable is 2c/9, not c/4. That is fixable, but requires re...

The two measurements that seem relevant to clock vs. pond, or clock vs. ship are seed size and glider synthesis cost. It so happens that you can hit a blinker with one glider and get either a pond or a ship. You can't hit any small ash object with a glider and get a clock. I'm not sure what the smal...
