A Sudoku question for the experts:
Suppose I generate a random Sudoku puzzle: Select a completed sudoku at random from the gazillion or so distinct sudokus. Then delete entries at random, stopping when nothing further can be removed without making the problem ambiguous....
How hard, on average, is the resulting Sudoku?
A related question is what the prob is that the resulting Sudoku is solvable without guessing. /Bernie\ -- Bernie Cosell Fantasy Farm Fibers mailto:bernie@fantasyfarm.com Pearisburg, VA --> Too many people, too few sheep <--
