I'm pretty sure you're mistaken.

Sudoku is a simple constraint resolution problem. The static constraints describe the rules of the game. The dynamic constraints are specified by the initial state of the board.

You seem to be implying that for some initial state (a partially filled board), there'll be only one correct solution (filled board).I'm quite sure that's not the case.

It's surely the case that for some problems where the board is mostly filled, that there is only one correct solution; I'd need to see a damn nifty proof to believe that is the case for all conceivable (and valid) starting states.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
