Sudoku, S-permutation matrices and bipartite gr...
32,90 € *
ggf. zzgl. Versand

The book examines some combinatorial problems related to the number of Sudoku matrices. The problem is reduced to the task of finding the number of mutually disjoint pairs of S-permutation matrices. We describe some algorithms that solve this problem. Essential role in the description of the corresponding formulas and algorithms play bipartite graphs and operations with binary matrices. Solving the main problem, we have discussed also other mathematical and algorithmic problems, which in itself are interesting.

A Glance to Digital Image Watermarking Techniques
32,90 € *
ggf. zzgl. Versand

The present work contributes to watermarking protection of digital image copyrights, and more specifically, the integrated methods of digital image watermarking (DIW) represented in recent Iranian publications. For each of the methods, the ultimate goal was to improve the attributes of digital watermark. Given that, several combined or novel watermark embedding techniques were proposed and applied in image blocks. For each of the proposed techniques, the model of watermark embedding and its parameters, as well as decompression and related flaws, the kind of possible attacks on watermarked images, etc. will be mentioned. When to copy electronic data, it is essential to maintain the copyright, therefore, there is not possible easily to do the forgery and manipulation of documents. The watermarking algorithms are proposed as solution for this problem. In this work, a review is represented about a number of proposed algorithms based on different aspects, and then a high yield algorithm is described named one-step Sudoku Table methodology that is more suitable for extracting the image.

Foolproof, and Other Mathematical Meditations
23,80 € *
ggf. zzgl. Versand

A non-mathematician explores mathematical terrain, reporting accessibly and engagingly on topics from Sudoku to probability.Brian Hayes wants to convince us that mathematics is too important and too much fun to be left to the mathematicians. Foolproof, and Other Mathematical Meditations is his entertaining and accessible exploration of mathematical terrain both far-flung and nearby, bringing readers tidings of mathematical topics from Markov chains to Sudoku. Hayes, a non-mathematician, argues that mathematics is not only an essential tool for understanding the world but also a world unto itself, filled with objects and patterns that transcend earthly reality. In a series of essays, Hayes sets off to explore this exotic terrain, and takes the reader with him.Math has a bad reputation: dull, difficult, detached from daily life. As a talking Barbie doll opined, "Math class is tough." But Hayes makes math seem fun. Whether he's tracing the genealogy of a well-worn anecdote about a famous mathematical prodigy, or speculating about what would happen to a lost ball in the nth dimension, or explaining that there are such things as quasirandom numbers, Hayes wants readers to share his enthusiasm. That's why he imagines a cinematic treatment of the discovery of the Riemann zeta function ("The year: 1972. The scene: Afternoon tea in Fuld Hall at the Institute for Advanced Study in Princeton, New Jersey"), explains that there is math in Sudoku after all, and describes better-than-average averages. Even when some of these essays involve a hike up the learning curve, the view from the top is worth it.

Number Theory - A Historical Approach
99,90 CHF *
ggf. zzgl. Versand

The natural numbers have been studied for thousands of years, yet most undergraduate textbooks present number theory as a long list of theorems with little mention of how these results were discovered or why they are important. This book emphasizes the historical development of number theory, describing methods, theorems, and proofs in the contexts in which they originated, and providing an accessible introduction to one of the most fascinating subjects in mathematics. Written in an informal style by an award-winning teacher, Number Theory covers prime numbers, Fibonacci numbers, and a host of other essential topics in number theory, while also telling the stories of the great mathematicians behind these developments, including Euclid, Carl Friedrich Gauss, and Sophie Germain. This one-of-a-kind introductory textbook features an extensive set of problems that enable students to actively reinforce and extend their understanding of the material, as well as fully worked solutions for many of these problems. It also includes helpful hints for when students are unsure of how to get started on a given problem. Uses a unique historical approach to teaching number theory Features numerous problems, helpful hints, and fully worked solutions Discusses fun topics like Pythagorean tuning in music, Sudoku puzzles, and arithmetic progressions of primes Includes an introduction to Sage, an easy-to-learn yet powerful open-source mathematics software package Ideal for undergraduate mathematics majors as well as non-math majors Digital solutions manual (available only to professors)
