This is a more submission for game 309 here: http://forum.enjoysudoku.com/patterns-game-t6290-36525.html#p265448, so goes back quite a few months, SE rates it ED=6.6/1.2/1.2. So I'm thinking that g.r.emlin does not validate more submissions! Found during the spare moments between games! I took all the submissions from games 301 to 320 inclusive to test various rating programs!!

I think that I have a worse example on a more done by me, I'll post it later. I have to catch it back and to check when it has been posted

re 258, i'm now curious,
do you have a 7.7 trump ?

[champagne]

i'm now curious,
do you have a 7.7 trump ?[/list]

No idea. Even if I still have the file, I store only one puzzle per rating except the for highest ratings. But in serate's code, a 7.7 diamond seems relatively difficult to find. I tried without success so far to "under optimize" the fresh code in the area {7.6 8.1} to be closer to serate. So, even with the fresh code

most of the ER7.7 of the clone are rated 7.8 by serate
the best chance to get a 7.7 diamond seems to rate a 7.6 diamond of the clone.

PS and the clone should be ready for preliminary tests up to ~9.0 (multi chains) for the next game
