The run on the highest ratings excluding the families is closed;
It gave only one solution grid with the rating 11.8

The start point, with the file of puzzles loaded in my google drive, was

Code: Select all
Er   CountOfpuz 
105   1444127
106   585504
107   35404
108   88019
109   459831
110   1038518
111   518569
112   19211
113   1615
114   1628
115   1408
116   1086
117   201
118   39


156391 sols
4195160 puzzles

Meantime, I made 2 small tests of the max expand process, and finished the process for a vicinity search started long ago on the high ratings excluding the “families” planned to be expanded one by one.

I stick to a cutoff of skfr Er>=10.5. Th final status of added puzzles after these 2 steps is

474884 new puzzles in 8886 sols
Code: Select all
Er   CountOfpuz
105   217717
106   81082
107   3589

113   1137
114   861
115   1186
116   699
117   88
118   2


The new sol 11.8 has the rank 12139724 with 61 puzzles rating >=10.5

Four solution grids have hits in different targets
982792 2 1107049 4252732 48893161

I wait for the closure of the first chunk of the biggest run (80 million fresh puzzles) to load a file with new puzzles in the google drive. This should come next week (end of this week at best)
