Re: Meanings of puzzle ratings
I would like to bump this thread again. Patrick, if it's not too much to ask, could you provide us with an explicit example of a rating calculation?
In the paper previously mentioned (
http://www.calcudoku.org/papers/choice_ ... _v1.01.pdf), you say that the 4x4 on the second page has a rating of 0. This would mean that every row/column only has 1 'possible' permutation. I can see why that would be the case for the columns, but not for the rows. For example, in the top row, you initially don't know the ordering of the 2 and the 4 in the 6+ cage, unless we also consider other cages.
Of course, we also still have the problem of ratings exceeding the maximum possible rating. Todays 4x4 difficult has a rating of 15.7, which is higher than anything I would ever calculate.
