Computational nanoscientist Surendra Jain has written solvers for Sudoku, Killer Sudoku, Samurai Sudoku, Calcudoku, Kakuro and many other logic problems.

All are elegantly coded and very fast: for example, the "World's Hardest Sudoku" is solved in 0.05 seconds (on a 5 year old PC) and his Knight's Tour solver is an order of magnitude faster than this one.

The page (called "Classical Geek") has all source (in Fortran 90, one of the most popular languages in high-performance computing) as well as compilation and running instructions.

    There as a typo in the coment. Does that disqualify it for elegant/cute status?

    Well, as a comment, it's rather superfluous. It's nearly the level of i++; // increase i by 1

      Nearly, indeed. It's more like
      i++; // increase by 2
