Re: 31c/240 caterpillar working notes

What about the head? It wouldn't be surprising if the first three Herschel-pair climbers could be moved back about 400 columns, correspondingly reducing the width of the whole structure by quite a bit. Then again, it wouldn't be surprising if chris_c figured out the math for those first interlockin...

Re: Simplified Demonoid in CGOL

I came up with a method of initialising a Gosper Glider Gun where the relative timing of the gliders only needs to be correct modulo 30. Hardly revolutionary but it could make P30 self-constructing spaceships a bit cheaper if it saves on OTTs. x = 153, y = 30, rule = B3/S23 99bo$100b2o$99b2o3$o$b2o$...

Re: Simplified Demonoid in CGOL

The clearance of an Fx119 based edge shooter is overkill. All we really need is a version of NW31 that is transparent two lanes towards the "inside" (transparency on the output lane is not even a requirement). Hence the following should be possible. In terms of population, the units are just over tw...

Re: Simplified Demonoid in CGOL

@dvgrn All valid points there. One other thing I realise is that we only need to use Fx119's on one side. The side not needing the clearance can stay as simple NW31's (oh, and get rid of the added Fx77's?). This would probably result in a saving but complicates the construction by bringing circuitry...

Re: Simplified Demonoid in CGOL

Did you check the 10hd Demonoid? I seem to recall that tookit is even faster (but it has twice as much to build, so it ends up in second place overall.) It's about 700 ticks per glider. I remember the advantage being greater but maybe I added more elbow varieties to the 0hd toolkit than the 10hd. H...

Re: Simplified Demonoid in CGOL

I did some rough measurements. The p30 construction arm in Remini seems to realease a glider approximately every 6000 ticks. For single arm construction it appears to be around 3600 ticks. The construction arm in the 0hd-Demonoid releases a glider about every 800 ticks. So the construction method in...

Re: Binary slow salvos

How is this even gonna be cleaned up? This old post shows that the debris trails from the glider-producing switch engines can be cleaned up with one glider and 11 Corderships. After that it might "only" take another hundred or so gliders to finish the cleanup. Admittedly this part is not very elega...

By the way, that's not quite a universal set just yet: you also need a mechanism to generate a hand block a sufficient distance from the elbow. I will try.

Re: Binary slow salvos

This is nice but the current 35-glider RCT cannot produce arbitrary binary strings. Call the two lanes A and B. Then it can produce a glider on lane A or gliders on lanes A and B in quick succession. Your salvos don't seem to be compatible with this. Some kind of workaround looks necessary to me bef...

Idea for simplifying part of the activation for one of the wings, inspired by spark-search.
