       | Uses constraint propagation, not any specialized sudoku solving
       | algorithms. But this person is a CSP expert and finds ways to
       | optimize CSP for sudoku in particular.
       | 
       | ... And then does it all in SIMD.

       | Ah, yes... remember the halcyon days of 2006, when something as
       | benign as _Sudoku_ was considered to be a  "denial of service
       | attack on human intellect"?

         | The same could be said about every logic puzzle, or other types
         | of puzzles.

         | People don't do them so actually solve any sort of new problem,
         | or achieve some sort of productivity.
         | 
         | The same reason people don't jog to get from point A to point
         | B, or to learn how to get around more quickly.
         | 
         | Logic puzzles are exercising parts of our brain that don't get
         | exercised regularly.
