Those are the so-called "dependent" conduits -- they interact with an active reaction three ticks before it becomes a Herschel.Ethanagor wrote:Tangentially related question: In the Herschel conduit collection, why are there some conduits that destroy the conduit immediately with a block, turning it into a traffic light and not giving the labelled output?
It's OS-specific. See File > Preferences > Control to see the path for your system. This came up just a couple of weeks ago.gameoflifemaniac wrote:Where are all the saved rules stored in Golly?
There's some kind of answer to that in response to muzik's question, in the lower part of this post. If you're optimizing population it seems hard to beat a design like the Demonoid with two 180-degree reflectors to hold the signals that run the universal constructor(s).Rhombic wrote:What is a good estimate/guess of the minimum population of the smallest possible universal constructor-based spaceship? (Gemini-like)
As in, how small would the smallest be likely to be?

The LifeWiki says in at least two places that the fourfold rotationally symmetric Garden of Eden 6 is the smallest known Garden of Eden. Which just shows how far out of date the LifeWiki can get sometimes. That was true for four years until Steven Eker started generating smaller asymmetrical ones, none of which have had their pictures taken for LifeWiki articles yet.

Others use multiple computers, like calcyman uses upwards of 20(probably innacurate because I forgot how much). I use one and occasionally run 2-3 instances.Rhombic wrote:I'm on a Core i7, and I ran apgmera with -p 4, but the rate at which hauls are submitted seems to be much higher for other people.
I've never tried parallel searching -- I just run several instances in parallel (makes it easier to shut down some when I need the CPU for other things).Rhombic wrote:I'm on a Core i7, and I ran apgmera with -p 4, but the rate at which hauls are submitted seems to be much higher for other people.
