Generating Sudoku Puzzles

Summary

This chapter combines all the techniques that you have learned in the past few chapters and uses them to generate Sudoku puzzles of varying levels of difficulty. While I have described the techniques to generate Sudoku puzzles, you can adapt the methods to further improve the quality of the puzzles. In fact, there are many areas of improvements that you might want to look into, such as adjusting the weights assigned to each technique that is used to solve a puzzle to further fine-tune the difficulty levels. Also, you can insert additional checks in the program so that the puzzles generated can have only one solution.
