24 more 39s from the first pass and the seed grew from 216 to 305MB.
Seems that there are much more 39s, giving a real chance for third 40-given to exist.

818,744 38s
79,089,207 37s

by **eleven** » Wed Jul 16, 2014 7:43 am

I made a quick look at the ratings (we know, that minimal puzzles with more givens tend to be harder).
The 39's have an average Explainer rating of 8, the first 150k 38's gave 7.8.
The two 40 clue puzzles are relatively easy (7.2).

What is the rating of the the easiest and hardest puzzles?

by **eleven** » Thu Jul 17, 2014 8:56 am

In the 39's this easiest one solves with a UR1 (ER 4.2)

Code: Select all: ........1.....2.3..24.13.....5..16...16738.4574..56.13.5..6...2.62387.5447..2536.

and 3 have a rating of 9.2

Code: Select all: 9.2 9.2 9.0 ........1..2.13.4514..2536..24.78.5.57.3.2.848...5.....8...7.1.2.7.8143.41.23...8 9.2 9.2 6.7 ........1.12.34.5.53..162.4..3.7.8.5.856.3.2772..8.4...5...7...27.36.5.83.1..8.72 9.2 1.2 1.2 ........1..2.13.4514..2536..24.78.5357.3.2.848...5.....8...7.1.2.7.814..41.23...8

In the part of 38's i rated, there were 24 singles puzzles, e.g.

Code: Select all: ..............1..2.12..3..4.25..6..71.6.57...47.132.56.516.4.3824.3.8.656...754.1

and twins with ER 9.3

Code: Select all: 9.3 9.3 2.6 ..............1234123.54.6..37.4...828..75.434....872..72.1..863.6..7..281...637. 9.3 9.3 2.6 ..............1234123.54.6..37.4...828..75.434....872..76.1..823.2..7..681...637.

Thanks, Eleven. So, the notable fact is the high average rating. Maybe also the absence of 39s and 40s solvable with singles, and the absence of 41+ solvable with any technique

.

Fortunately the 39s reached 1500.
These are the sizes of the latest generations. At 65th and 66th generations 15% of all 36s were used as seed. What is your updated estimation for the total number of 39s?

Something between 2000 and 60000

However i like the "smooth cspline" curve best for 5000 39's and 3 40's.

But look at the curves for the Titius Bode law, who in the 18th century found a simple formula for the distance of planets to the sun, which now turned out to be very good also for other suns (and no one knows why). Then you know, how sure i am, that my curve is correct.

by **dobrichev** » Fri Aug 01, 2014 8:59 pm

He too likes the smoothness and all defects are resonances.

Seeing the latest progress, my re-estimation of the upper limit is maximum of 5000 39s and possibly few more 40s.
