"kuto" is likely a new tridagon family of interest. As it starts in TE2 (coloin's check), it should not hit mith's TE3 file.

"kuto" appeared in the vicinity of a puzzle coming out of the direct search of non degenerative tridagon. It is my first skfr 11.8 derived fromt he search.

the start is in the solution grid 537529786

This solution grid has automorphism, what is not so common.

Here four 11.8 appearing in a vicinity with a quick check ignoring the auto morphs.

all have the same "canonical" name

This forces to put all results in the canonical morph, what is the normal secured way to get only new puzzles.

The first "slightly expanded seed" used in the vicinity has been

Code: Select all

.23...7.945.....327.9.3.54.2.53...9439...5.7..47...3.5...8....7..4.2.......6..... 


having six minimal puzzles

The seed is likely one (or more) of these rated skfr 11.6

16128677 m5TO6J2CEH8042
16128677 m5TO6I2DEH8042

I started the vicinity on the high ratings. The first cycle was relatively short, I then started a second cycle in test mode with a lot of redundant seeds.
As I run in parallel a big test with the primary seeds of my scan, I could not run many cores and I have only partial results to show, what will come in the next post.

[champagne]

After the first vicinity search on “kuto”, I built a file of seeds expanding the results of the first cycle.
I am running the vicinity on a file of 751 expanded puzzles with 29 to 39 clues. The final result is expected later this week, but I checked the status halfway.

Having cleared all redundancy, I have now more than 1800 puzzles in 43 solution grids rating skfr >=10.5 with the best below

Many more solution grids appear if we consider lower ratings. I’ll check this at the end of this cycle.
Meantime, my big test on the primary seeds of the scan should be nearly over, giving free cores to continue the vicinity search here.
