Dear MM,
Do you perhaps have an estimate of the number of ED symmetrical WX grids?

Thanks,

A filled pattern is tested with BF method:
0 solution is invalid
1 solution is valid
2 or more solutions is invalid and the BF method is cancelled and not written to file.
On the rare moment the user hits STOP between the 1st found and the 2nd found, BF is cancelled with 1 found en will write this filled pattern to file. And PGExplainer will rate it with 20 points.
SiSeSuSo is in error. This and some other minor bugs keeps me from publishing the next version.

A case that PGexplainer will rate as 20.0 and Sukakuexplainer from Sudokumonster will handle because it has more advanced solving methods and not as result of a possible error from SiSeSuSo described by Hajime above.

PGExplainer only rates vanilla sudokus for the Patterns Game.

If you define "symmetrical", I can scan the ED grid set accordingly.

Better still, just PM me with an email address, and I'll send the ED grid set to you (6.8MB txt, 1MB zip) ...

I found 457 WX grids with symmetry. Here are the first 10:

Dear MM, Thanks for your file. I made another generation run using your grids, but nothing dramatic turned up. A few are listed below (but renumbered). Interestingly, 8 of the 14 have only 8 distinct clue values (true also for 10 of the 12 in my previous posting).

Regards,

Mike
