Negative Positive
Title: Superficial
Review: This book might be an interesting case study for a novice Visual Basic programmer -- it devotes a lot of ink to UI programming -- but for someone interested in algorithms for solving and generating sudoku puzzles, there's not much value here. Only the most elementary human-style solving techniques are discussed. The reduction to exact cover and the dancing links algorithm aren't discussed at all. The author's puzzle generation algorithm is not guaranteed to produce a valid sudoku puzzle (one with a unique solution) except for the easiest levels of difficulty. You'll learn more by surfing the web for a few hours (including visiting the Sudoku Programmers Forum) than you will by reading this book.
