Sudoku cheat

Hi, long time no blog! I just realize that I already had an awesome model to cheat the sudoku game. Last month, I bought the puzzle book to prove that my model wasn't wrong (actually, i'm think about won the price by cheating, lol). My project was about sudoku solving model from optimization method subject, I have to model and doing research about sudoku, what is the model, what's the different between using IP and CP, how was bigger problems, how was another rule of sudoku... etc. Actually my grade was not good, I got B+ with 79 points (- -") but i would say that the project introduce me how to model with IBM iLOG, knowing about sudoku in deep and it was fun to work with the game i like. ;) But my document still needs to improve.

Sudoku is a number placement puzzle based on logic rather than mathematics. Sudoku gained worldwide popularity in early 2005 and began selling in the form of puzzle books, handheld electronic versions and board games, as well as appearing in thousands of daily newspapers.

The concept of Sudoku is simple. The puzzle consists of a 9x9 square grid that is divided into nine 3x3 squares, resulting in nine rows and nine columns, for a total of 81 small squares. The unsolved Sudoku puzzle supplies only a few numbers in random squares.

To solve the puzzle, the remaining squares must be filled in with the numbers 1 through 9, each appearing only once in each row, column and 3x3 square.

There are more informations, model for both IP and CP and some another rules of sudoku, you can find out from my document

Actually, I already record my video when i was using my model to solve the puzzle from the book but I'm too lazy to edit the video. But it works for all puzzle from the book! (of course!) I'll show you later if I have time to edit it.
