Although gB analysis is slow and takes a long time, perhaps a month or more, three record-breaking gB30 puzzles have been found among the puzzles that have been analyzed.
These puzzles are all in _yzf6.zip.

Hi yzfwsf,

congratulations first for your records breaking limits in the Bn and gBnn field.

This shows once more that the key point is to get a feed in the appropriate area.

Here we have very old puzzles (>10years old) from my seeds control file for the 20-23 clues area.

The skfr rating does not bring much more

Code: Select all

98.7..6....5.4...........7.7..3...9..2...5..6..1.8....3..8....7.1....98.....2.3.. ED=9.3/1.2/1.2
98.7.....6...9.5....5..6.7.4.......3.3...2.....95..6....89..7......1...2.....4.1. ED=9.5/1.2/1.2
98.7.....7.....86...6.5....49......3..75...9......21....96...8.....14..2......3.. ED=9.6/9.6/3.4

I did not ckeck the other properties, but our experts in solving will tell you what is the best path if you post them to be solved.

As I am working to-day in this area (in parallel with a last ongoing cycle based on paquita's start), I could have new feed in the next weeks for such puzzles .

Hi yzfwsf,
Good to see these sleeping files of puzzles in the grey area used.
I let you work with the stuff already posted.
Just to let you know, I made some progress in an "expand" step on the old file of potential hardest, keeping many puzzles in this area.
In due time, we can see what is there. (thousands of puzzles with your skfr ratings target already available)

These puzzles could beat the Bnn record

Hi yzfwsf,
I'm not following this thread and I would have missed your posts if someone didn't pointed them out to me.
Congrats for these findings.

Could you give some detail on how you found them? It seems you started from the minimals in ph2010, used BRT-expansion (or perhaps further expansion such as BRT+1) and then minimised the puzzles thus obtained - which would be perfectly reasonable considering my results for high B puzzles obtained in this way.
