Hooked on su doku? Then move on up to kakuro! Kakuro is the latest Japanese puzzle craze for all those who thought they had reached the limit in logic puzzles. Kakuro is all about numbers, and like su doku it is solved by using logic, with absolutely no guesswork. However, Kakuro takes puzzling a step further: it requires simple arithmetic skills as well as reasoning. But don't worry if maths isn't your strong point. While some of the logic relies on you being able to add up, the sums only ever involve a few single digits, and the totals in this book are never more than 45. You don't need to be a maths whiz, nor do you need to have a calculator handy. You will have no difficulty in doing the sums in your head. As with the incredibly addictive su doku, the fun in doing kakuro is working out the logic that gets you from the starting position to the single solved grid of digits. So if you're bored with su doku - kakuro is the next logical step . . .

OPL (Optimization Programming Language) is a new modeling language for combinatorial optimization that simplifies the formulation and solution of optimization problems. Perhaps the most significant dimension of OPL is the support for constraint programming, including sophisticated search specifications, logical and higher order constraints, and support for scheduling and resource allocation applications. This book, written by the developer of OPL, is a comprehensive introduction to the OPL programming language and its application to problems in linear and integer programming, constraint programming, and scheduling. Readers should be familiar with combinatorial optimization, at least from an application standpoint.

Appearing daily in the newspaper, Codeword is a popular alternative to Su Doku and Crosswords. The concept is simple: each number represents a letter, so, starting with the solved letters, use your logic and vocabulary to reveal more letters, form words, and then crack the code! The Codeword series is so popular because you don't need any prior knowledge, unlike a crossword. You can just pick up a pen and get puzzling. It steadily increases your vocabulary, as the difficulty slowly grows as you progress through the book, and even though you'll be working your brain, it's the perfect way to unwind.
