Subject: Re: [Caml-list] Sudoku solver

And what about a sudoko generator with a pertinent notion of level for a 
human ? Would be nice if you could choose the cases that are filled from 
start ...


a start for level for problems with a unique solution :

- negative level -n : number of times where you have to do deep 
reasonning (guesses) because you do not have an immediate choice.

- positive level n : minimum of the number of cases that can be filled
by an immediate choice on all branch ?

These are not formal definition ... yet, but using a representation of 
the problem as a set of close, I think we can do something with the 
complexity of the proof search ...

just for fun ...
