Oops I have just realized my oriented construction idea would not work.
I have planned to build by huge OGGCA on input lane ... and for NW neighbour there is actually just part of the input lane.
We should bend once before long OGGCA ....
I have planned to build everything except SSSS and half of SSSW using this OGGCA then bend twice to finish SSSW and SSSS.
The positions of oriented targets are in rather good places, But I have planned fast pull for clock allocation from NWWW while building the monstrosity in its SE part.
Build in perpendicullar direction would not help.
So what are the options now?
Bend twice early to finish SSSS and SSSW ... and build extra snark on SSSS WWWW diagonal, destroy he original 2 bends and build OGGCA near EEEE-NNNN diagonal ... to use the original direction of slow salvas? That looks like big waste of time to wait for creation of OGGCA on east. I am afraid the budget would not suffice...
Maybe we could just replace the second band as the SSSS-WWWW diagonal would be finished ... and destroy the first bends at the very end.
Actually it would be probably cheaper not to build the original OGGCA at all and start with the double bended.
Original plan was to have first optimized to NE direction while the other to SE, but building just one would probably be cheaper.
I would probably build snarks on positions the distant target is already built, so snarkmaker variant not making the target would be better then one destroying target afterwards…
I would probably shift SS, WW, NN, EE targets such that it can be used as speboe after first bend and allow to build SS snark by one of the OGGCA's (after another turn in either direction).
OK, start with double bend near SSSS and then changing second band direction looks reasonable.
... oops I have almost made the same misteke second time ... to make OGGCA from perpendicullar glider in the input stream ... which is missing on NW neighbor
. ... so how to make target for OGGCA close to EEEE around EEEE-NNNN diagonal? Should I prepare it during the shell build?
I am still thinking about good enough plan to build the oriented portion ... something like this:
Seems first OGGCA could be after double bend to from SSSE->almost SSSS->a bit to SSSW -> SSSS such that most of OSSSS would be built on its "better side" and just the DNA fill snark would be build by its "worse side" ... the OGGCA would build WWWW and SSSW before building SSSS.
The other OGGCA should be at NEEE working on SS-NEEE diagonal building ONNNN first, ONNNE second by its "better side" and than OEEEE by its "worse side". Reason: NEEE blocks the diagonals EEEE-NNNN required for the NNNN construction. Luckily NEEE does not block EEEE construction diagonals.
Thereafter it would build NN and EE on the better side, and SEEE on the worst. It should create ott's on NNNW and NN and use synchronized long pull trick to create targets on NNWW and NW using them. Then ONNWW and ONW should be constructed and maybe ott and long pull creating target on NWWW.
Then ONWWW construction starting with long pull to clock NW postion, then NW construction. SW construction finishes the task. and we can destroy the OGGCA and both snarks to let the gliders fill the DNA loop.
OGGCA stop/destruction should be well timed and seems we could use snarkmaker without SoD for the task .. probably OGGCA would be destroyed much later then the snarks. (Escaping gliders from the stop would be used for snark destructions while the OGGCA destruction salvo would be headed to OGGCA)
I probably should build target for 2nd OGGCA at NEEE (with copies on NNNW, SWWW and SSSE to be just destroyed by O construction).
I probably should reposition SS (WW, NN and EE) target as well to allow constructions on SSSE, SS, WW, NWWW diagonal with the 2nd OGGCA (after the bend).
. It seems to me I luckily chosen the correct size for the cell (DNA length).
