Tangram Puzzle Book, The: A New Approach To The Classic Pieces
THE TANGRAM is one of the oldest types of dissection puzzles in the world that originated from China. It traditionally requires the participant to arrange seven pieces (or 'tans') into a shape just by looking at the given silhouette.LEARN WHILE PLAYING The puzzles in this unique book are fresh, innovative and compelling. The puzzle pieces are building units for puzzles that boost mental dexterity with a variety of challenges from various fields of recreational mathematics. Come on and play with symmetry puzzles, cover-up puzzles and self-similarity puzzles to increase your skill and mental acuity!NEW PUZZLE DESIGNS To add variety and challenge, some of the puzzles may not use all seven piece...
303 Three-Minute Puzzles
This latest collection from the famed Grabarchuk family--the preeminent creators of brain-teasing eye candy--bursts with color and creativity. And each one of these 303 diabolical teasers must be solved in three minutes or less! Brainiacs in search of a treasure trove of terrific teasers will find these perfect . . . and perfectly challenging.
The Art of Computer Programming
The Art of Computer Programming is Knuth's multivolume analysis of algorithms. With the addition of this new volume, it continues to be the definitive description of classical computer science. Volume 4B, the sequel to Volume 4A, extends Knuth's exploration of combinatorial algorithms. These algorithms are of keen interest to software designers because ". . . a single good idea can save years or even centuries of computer time." The book begins with coverage of Backtrack Programming, together with a set of data structures whose links perform "delightful dances" and are ideally suited to this domain. New techniques for important applications such as optimum partitioning and layout are thereby...

Kopfnuss
er bekannte Physiker und Mathematiker Heinrich Hemme unternimmt einen Streifzug durch vier Jahrtausende mathematischen Denksports. Kopfnuss enthält 101 Rätsel aus allen fünf Kontinenten; die ältesten stammen aus dem zweiten vorchristlichen, die jüngsten aus dem dritten nachchristlichen Jahrtausend. Der mathematische Denksport ist so alt wie die Mathematik selbst. Als vor über viertausend Jahren in Ägypten und in Mesopotamien die Mathematik entwickelt wurde, merkten die Menschen, wie viel Vergnügen es bereiten kann, knifflige Probleme zu lösen, und schon bald wurden mathematische Knobeleien erfunden. Gute Knobeleien sind kleine Kunstwerke. Kopfnuss stellt aber nicht nur die Rätsel selbst vor, sondern berichtet auch über ihre Herkunft sowie über die Künstler, die sie entworfen haben. Von anderen Rätselbüchern unterscheidet den Band zudem, dass alle alten Originallösungen durch moderne und ausführliche Beschreibungen ersetzt wurden.
Strimko 4x4
Strimko is a logic number puzzle invented by The Grabarchuk Family in 2008. It is based on the idea of Latin squares described by a Swiss mathematician and physicist Leonhard Euler (1707-1783) in the 18th century.All Strimko puzzles are solvable with a pure logic, no special knowledge is required. Strimko uses only three basic elements: rows, columns, and streams. All elements have equal numbers of cells, and the goal is to make each row, column, and stream containing the whole set of specified numbers. Cells in the grid are organized into several streams of equal length, which often run diagonally and even branching. Such mechanics creates entangled patterns resulting in interesting challenges and unusual logic. This book contains a specially designed collection of 150 easy puzzles with 4 x 4 grid sizes. Puzzles are arranged from the easiest to the hardest ones so that you'll progress in solving skills with each next puzzle.Strimko challenges were handcrafted by Helen, Tanya, Serhiy, and Peter Grabarchuk, and up to date hundreds of original Strimko puzzles were published in various forms and platforms.
