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 ...
