Solving Sudoku with Simulated Annealing

How long would it take you to solve this devlishly hard Sudoku puzzle (from Le Monde)? You could do it the old-fashioned way -- with a pencil -- but Xi'an decided to solve it by programming a simulated annealing solver in R. The algorithm works by first guessing a solution at random -- filling in the empty cells above with random digits between 1 and 9. Then it "scores" this solution by counting the number of digits duplicated in all the rows, columns and blocks. Next it evaluates a number of candidate new solutions by tweaking one of the free
