Sudoku Heyawake - 200 Master Puzzles 14x14


Book Description

Heyawake (from Japanese, "divided rooms") is played on a rectangular grid. The grid is divided into rectangular "rooms". Some rooms may contain a single number. These rooms must have the designated number of cells painted black. Other rooms may have zero or more cells painted black. Black cells must not be orthogonally connected. All white cells must be interconnected. A line of connected white cells must not connect more than two rooms together.




Absolutely Nasty® Kakuro Level Three


Book Description

Kakuro is a puzzle type in which sums are given and solvers must deduce the numbers in the individual boxes. This title is suitable for hardcore kakuro devotees.




The OPL Optimization Programming Language


Book Description

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.




Problem Solving Through Recreational Mathematics


Book Description

Fascinating approach to mathematical teaching stresses use of recreational problems, puzzles, and games to teach critical thinking. Logic, number and graph theory, games of strategy, much more. Includes answers to selected problems. Free solutions manual available for download at the Dover website.




Mensa® Kakuro


Book Description

What could be more appealing to Mensa members--or anyone who enjoys a good challenge--than a cunning test of intelligence and logic? That's exactly what these 250 puzzles provide. The trick to kakuro is in making it all add up: the game begins with a grid that looks like a crossword, except that some squares contain small numbers in the corner. Fill in all the empty boxes using the numbers 1 to 9 without repeats so that the sum of each horizontal set of digits equals the number in the black triangle to its left, and the sum of each vertical set of digits equals the number in the triangle above it. The kakuro puzzles start out simple...and get more difficult as the book progresses.

Round Trip Puzzles


Book Description

Take a fun trip around the puzzle page! "Round Trip” puzzles feature a square or hexagonal field of dots, in which certain dots are connected with lines. Players must then connect the rest of the dots until they result in a single, connected loop. The solution can then be traced from one point all the way around and back to the starting point. The puzzles provided here range from small and simple to large and extremely challenging.
