Thanks. I indeed missed some of the micro-optimisations, especially the ones requiring lane change. But at least these micro-optimisations are probably the most important ones in the RCT project, given that they make slow^2 gliders of the most expensive arm more efficient. Updated variant: Yes, the...

@Pavgran, do you still have the tools to compile this into a seed? Yep. I adjusted some of lanes and phases to minimise cost. The recipe is small enough to do it by hand, so I didn't bother writing script for it. There's what the final activation glider looks like (it's in correct phase mod8, we wo...

I have not tought about optimiation of the 2 p8 refectors recipe using one time turners. I suppose you used expected color phase one turner build costs when optimizing it. When there is an option to chose a cheaper phase, I hope you did it. That was calcyman's idea and initial design, but that part...

If there are no objections, I'll try to build this with pslmake. I have not tought about optimiation of the 2 p8 refectors recipe using one time turners.

... initial configuration not checked yet Thanks! After flipping the state of a semisnark in the initial pattern and making a correction on glider #18 for the 12hd discrepancy, it works perfectly: #C recipe == 1 212 212 212 212 212 212 212 212 212 212 212 212 212 #C 212 212 212 212 212 212 212 212 ...

Oh you probably asked for binary bits to feed nonwhite portion with. I have done just manual preparation for yellow gliders… 4 variants depending on initial state of the DBCA… Yes it would be nice to finish the DBCA varianted levels to bits compiler from given initial configuration…. Not done yet. ...

To me, 'dependent reflector loop' accurately describes this particular type of oscillator. The word 'signal' doesn't feature in 'dependent reflector loop', so even though I agree with confocaloid's point that these* dependent reflectors cannot reusably transmit information, I don't see why that shou...

Oh it is more complicated: I have added the constraints (we can choose A,B,C,D,E) simillar rules could be used anywhere, but I hope using them on other phases is not worth the complications. -- if we add [X define variable X and X] end of scope of variable X, we should extend the DP state by all de...

I believe that was necessary because there are (mod 2) phase constraints: the perpendicular gliders are forced to be in the same phase as the salvo gliders. Oh I forget to think about that, yes, they are mod 2 phase constrained, but seems the are in opposite phases. That's fine: the phase differenc...

Unfortunately I have not tried codding agnosticize for the case of interfering perpendicullar gliders ... maybe doing the first few gliders by hand ... Beyond those first few gliders (in yellow) which don't need to be changed at all, there's no risk of perpendicular gliders because I ensured that t...

I ran into a problem when searching for a (2,1)c/7 knightship. Three times the program crashed due to some kind of error.

Yes, it's a bug in Jannis Harder's incremental version of kissat that causes segfaults sometimes. Commit 27bc3beb shouldn't segfault.

Nonwhite color agnosticised (except the initial part where perpendicullar gliders interfere) (glider lines have to be changed by some additive constant): ..

It costs 905 monochromatic gliders to build the entire white section: 885 gliders by improving how pslmake handles spanning trees. This took about 2 hours to produce the salvo: Nonwhite color agnosticised (except the initial part where perpendicullar gliders interfere) (glider lines have to be chan...

Defragmentation of the slow salvos. This is already done very well by vanilla slmake. (Yes, it's frustratingly slow, but that's only really a problem when you have > 10000 gliders. In any case, I have some preliminary ideas for parallelising this step, so I'll work on implementing this in pslmake.)...

I expert bigger X_i sets depending on current DBCA configuration including arm block position (agnosticised salvo is the input) and 3 semistates. But we can prune vertices not on optimal paths during the search. The block arm position is determined by the last glider fired, as are the states of 3 o...

We have roughly the following ineffectivness ... Blinker arm ... 80 bits/glider, DBCA 13 bits per glider, ECCA 7 bits per glider. What is ratio of ineffectivity of unrestricted / monochromatic salvo?

Creating a monochromatic slow salvo for the white part of the DBCA. I've prepared HoneySearch databases of monochromatic salvos, so I could convert these into a pslmake database and then see whether it works. There's the issue of ensuring that the construction doesn't interfere with the constructio...

The only remaining cleanup tasks are for the trails left behind by the switch-engines. Owing to that backward stream of gliders from one of the switch-engines, we probably want to have the Corderabsorbers near the *source* of the switch-engines, and launch the Corderships from the far end (travelli...
