Re: Vaccinated glider loop challenge

An option to do to it with an unknown period is to make a glider pair delayed by 77 ... We're not really allowed to do this, I think -- the "vaccinated glider loop" disallows any 76-tick or 77-tick gaps, because that could cause horrible explosions in the unknown mechanisms that are bouncing the lo...

Re: Vaccinated glider loop challenge

I guess an upper bound for P is needed then, but I cannot see how that can be useful, as the actual P might be magnitudes smaller... Yeah, the real challenge seems to be "Define a version of this problem that doesn't have a boring answer like 'count up to the upper bound of P while cleaning all the...

Re: Vaccinated glider loop challenge

However, given the conditions you've specified, I can't see how the mechanism can possibly know for sure that its task is complete -- so it will have to keep deleting and re-adding gliders forever. Indeed, the mechanism itself might never be sure it is done, it only sees delays sequentially, and he...

Re: Vaccinated glider loop challenge

Same as before, but the period P of the glider loop is unknown but finite. "Same as before" meaning the added mechanism still has to fill the period-P loop with the maximum number of gliders? I can see how to build a mechanism that can be activated by a signal from the (Y >= 0) half plane, that wil...

Re: HBK Synth and Gun (script)

And that's a nice change from the cross-style herschel-loop guns of pretty much every gun in existence (CGOL). Nice construct! It would be great to see a few more guns build along these lines. I think that p5603 2-engine Cordership gun is still the only modern example. A number of other spaceship r...

Re: Vaccinated glider loop challenge

I do believe it is possible, but I now think that designing still life circuits will be awfully painful, as one would have to do a lot of comparison of delays to get the exact number for the delay. Why would you care of the exact number? Well, you cannot remember the other delays on the loop, but y...

Re: The Spirallers Question

The type-2 and type-3 spirallers are an interesting idea. They're certainly possible, and they're different from any of the self-constructing spiral patterns that have been constructed so far. The point of previous patterns was to achieve linear population growth but logarithmic bounding-box growth,...
