History

On 3 January 2011, I proposed to Apress to publish a book about writing programs to solve and generate Sudoku puzzles. As they were not interested, I went ahead and, on 23 April of the same year, self-published “Sudoku Programming” with Lulu. Then, on 3 December 2011, I published an equivalent book for Java programmers: “How to Create Your Own Sudokus with Java ”, also with Lulu.

You can imagine my surprise when on 18 November 1914 I received an email from Apress asking me whether I was still interested in publishing a book about Sudoku programming with them! It goes [almost] without saying that I accepted their offer, although the book contract included the condition that I would have to retire the books I had self-published on the same subject.

The Apress book is much better than the original “Sudoku Programming” because it gave me the opportunity to use the improved algorithms I had developed for the Java version of the book. I also extended the contents of the book to include the generation of symbolic puzzles

and a comfortable way to create of multi-grid Sudokus.
