Found a bug in SS which could affect many puzzles & their scores. Back later - hopefully not 5 months this time!!

Rating Assassins
Richard's SudokuSolver v3.0.0 rates this as 0.48 and also 0.60 depending on
how I open the file. However if a puzzle ever deserved a rating of 0 it is
this one. I have been very interested in SudokuSolver ratings and have
used it to rate many puzzles from different sites with fascinating results.
I applaud the effort to get a rating scheme is - it is well worthwhile.
But - let me know what happened to this one.

Ha, nice one Frank. Richard loves bug-finders! He'll enjoy that one.frank wrote:Richard's SudokuSolver v3.0.0 rates this as 0.48 and also 0.60 depending on how I open the file. However if a puzzle ever deserved a rating of 0 it isthis one
0.48 is the equivalent of a zero rating. We've always called this an Assassin killer scoring project - not killers in general. As you can tell, SS is not so good at the bottom end and tends to squash them in pretty tight. Ruud's software method that he was working on with SumoCue (unreleased) was much more aimed at the lower end and spread those out much more.
An update here on any generalizations/observations/results would be very interesting, especially as I'm a regular lurker elsewhere (sadly not Frank's for a long while ).frank wrote:I have been very interested in SudokuSolver ratings and have used it to rate many puzzles from different sites with fascinating results
Thanks! Richard has a long list of wish-list changes to SS(v3.0) (hidden killer triple, ALS cage block, killer quad etc) including many things for other formats, so the next V of scoring won't be for a good while.frank wrote:applaud the effort to get a rating scheme is - it is well worthwhile
Just to restate my last update - SSscore(v3) is only reasonably accurate up to about 1.40. It will usually err on the lower side. This is because "easier" puzzles that have a long solution set the maximum at about 1.40.
Thanks for your interest.
