I think LSSS with automatic adaptive widening would be the holy grail of oblique spaceship search programs. In 2020-21, Exa made immense progress on (2,1)c/7 with LSSS, but they had to perform the adaptive widening manually, painfully, and suboptimally. I conducted a few searches using this manual p...

No 3c/11o ships in width 7 asymmetric, 13 odd, 14 even and 15 gutter.
What program did you use to check this? What were the longest partial results?

qfind v2.2, I forgot to save the partials

Negative on 2c/10 logical width 7. Asymmetric, odd, even and gutter.

lordlouckster

Apparently I forgot to search c/11 gutter width 13, so I searched it, and so there are no orthogonal c/11 ships at logical width 6.

lordlouckster

May I get a "trusted" flag?

lordlouckster

I have confirmed using qfind 2.2 that no ships exist at c/11 at width 11 odd and width 12 even bilateral symmetry.
I am in disbelief that no one had searched this before
