simsim314 wrote:Also as a thought it might be possible to create some part of the new copy using direct shoots from the salvo itself, which might make it even faster than current Geminoid. Of course tweaking the Geometry is necessary, placing most of the "mass" of the new copy in the "shoot range" of the salvo.

simsim314 wrote:I've "proved" universality of this constructor. Using trial and error I've found the bounds of both white and black glider shoots. Using a little bit modified recipes for arm movements it's easy to see that the bounds of the UC shoots are much wider than the trace of the lowest and the highest gliders in the recipes. To shoot a different color glider, one should move the block by (2,1) and use the same recipe.

simsim314 wrote:...I'm conducting some experiment with small width salvos. I noticed that the current recipes didn't consider "glider range" as optimization parameter... I'm currently investigating what is the smallest salvo width for "Universality". But Before that, I just want to have a "thin" recipe collection.
simsim314 wrote:I think it's more theoretical question, what is the smallest UC possible? Even if really ineffective. This question also has few meanings: is only Spartan components are permissible? or any still life? For computers guns and such there is no reason not to use the most advanced technology available, but for replicators it's better to use the Spartan toolkit.
simsim314 wrote:The other question which is more "practical" is: what is the smallest "Full Range" opposite collision UC. For this one I really need the Herschel covered.

simsim314 wrote:By the way do you have some "conventions" for salvo recipes? I saw that you have script for some "code", but I couldn't understand it, just saw it worked. I could do some "reverse engineering", just find gliders, recognize their locations. But if there is something out of the box, simple enough, I could definitely use it.
EDIT: I've found this one http://conwaylife.com/forums/viewtopic.php?p=8186#p8186 and it's definitely was understandable. The only question is what if I want to create some "pattern" is there a recipes for still life creation as well?
EDIT2: I've found this one http://conwaylife.com/forums/viewtopic.php?p=9590#p9590 but it's definetly a partial info, that does not include the location of each still life that was created.
simsim314 wrote:I think we need some standard notions for still life, their orientation and locations (like we have for gliders). I guess you have some "standard" as a working prototype that you used in the Geminoid project, but I can't find any mention of it.
simsim314 wrote:So first of all I've found a way to diagonally move traffic light with 2-3 glider shoots, and 4 range by your notation (I didn't get how you calculate range, for me it's just natural to use glider level of freedom. So having only 3 levels of freedom or making a mark of 6 "blue horizontal cells" in LifeHistory), I managed to create all necessary movements.

simsim314 wrote:Another though[t]: if we will use this arm-less approach for UC's, and use two units so we have 90 degree instead of slow salvo, I don't think we have good recipes for the parts that "outside the bounds" except of slow salvo (X2 because we have two units). It's probable that placing "outside the bounds" can be optimized with "90 degree" two glider shoot. Kinda "90 degree-two-glider based slow salvo".

You said you have a db of all those recipes, you just don't have time to compile a query? Or is it all somewhat more "messy"?

...I wanted to use the same idea, to take recipes from Gemini two arm construction. It's also not as trivial as it seems, Gemini uses pretty advanced placing patterns that go to the edge very efficiently.
