The book is broad in scope and gives equal space to the classical counting techniques and to more recent methods. I used the book to teach a small group of graduate students. It was a rewarding experience. The material was interesting, diverse, and challenging. this is a book I heartily recommend to anyone wishing to learn or teach combinatorics." (Jeannette C. M. Janssen, SIAM Review, Vol. 26 (1), 2004) "The author has covered a huge amount of ground in this book. Each topic is covered in a way that takes the reader from the start right up to the most recent results in the area. the book is clearly a ‘labour of love’. The author’s enthusiasm for the subject shines through page after page: it is hard not to feel his excitement as one reads what he has written."

How many ways are there to make change for $1 using unlimited numbers of coins of all denominations? Each way is a combinatorial object. AMOF is part encyclopedia and part calculator, a teaching tool that generates mathematical permutations for such combinatorial objects as subsets and combinations, partitions, magic squares, and Fibonacci sequences by allowing the user to define the parameters of discrete objects. The Object Factory returns a list of all objects that satisfy those parameters. The site can be used to learn more about many types of discrete mathematical structures; descriptions of objects progress in complexity for students at different levels.

Ph.D. Program in Algorithms, Combinatorics, and Optimization ACO Home Page Admission Information Program Description Affiliated Faculty Students ... Contact WEBmaster Georgia Tech's Ph.D. Program in Algorithms, Combinatorics, and Optimization Algorithms, Combinatorics and Optimization (ACO) is an elite multidisciplinary program sponsored jointly by the College of Computing , the H. Milton Stewart School of Industrial and Systems Engineering , and the School of Mathematics . The Program sets very high standards for admission and graduation , and boasts world-class faculty with research interests spanning a wide expanse of topics, from ones purely theoretical to others more applied. The ACO Program curriculum provides required course work designed to ensure that students have a strong fundamental academic base that serves to facilitate and enhance their research options. We have essentially eliminated the traditional walls that usually separate academic units: any affiliated faculty member can supervise the research of any ACO student regardless of departmental affiliation. All we ask is that the work produced be first rate. ACO alumni have been very successful and have won prestigious awards from a variety of research and professional societies. Graduates of the Program can be found in myriad settings in both academe and industry; some have even chosen careers in finance.

Home Activities Special Programs Algebraic Geometry ... Sitemap Arithmetic Combinatorics (Term I 2007-2008 Academic Year) Mini Conference December 10-12th During term I of the year, School faculty member Jean Bourgain and Van Vu of Rutgers University will lead a program on arithmetic combinatorics. The following is preliminary information about the program. Additive combinatorics deal with problems in number theory with combinatorial flavor. While this theory has been developing for many decades, the field has seen exciting developments and dramatic changes in direction in recent years (a well known example is Green-Tao theorem about the existence of arithmetic progressions in primes). In this focus program, we will bring together active researchers in this field and many related areas such as number theory, combinatorics and theoretical computer science. Mini-courses: Jean Bourgain: Sum-product theorems and applications ; Oct 10, Oct 17 (2-4pm). A. Gamburd: Sum-product estimates and expanders; Nov 15 (2-4pm) Ben Green: Nilsequences in additive combinatorics ; Oct 24 (2-4pm) Van Vu: Inverse theorems and random matrices ; Oct 11, 18 (2-4pm).

36. TestLothaire This is the third book in the Lothaire s series, following the volumes ``combinatorics on Words and ``Algebraic combinatorics on Words already published http://www-igm.univ-mlv.fr/~berstel/Lothaire/

Lothaire's Books This is the third book in the Lothaire's series, following the volumes ``Combinatorics on Words'' and ``Algebraic Combinatorics on Words'' already published. Available at Cambridge University Press since july, 2005 Its objective is to present in a unified manner the various applications of combinatorics on words. The application areas include core algorithms for text processing, natural language processing, speech processing, bioinformatics, and several areas of applied mathematics such as combinatorial enumeration and fractal analysis. The intended audience is the general scientific community. No special knowledge is needed, and familiarity with the application areas or with the material covered by the previous volumes is not required. In particular, the content, including problems and algorithms, is accessible to anyone working in the area of computer science. As with the previous volumes, this book is written in collaboration by a group of authors, under the guidance of the editors. Content Implementation of algorithms Solutions to problems This book covers developments on new topics in the domain of Combinatorics on Words.

37. Problems In Graph Theory And Combinatorics" A collection maintained by Douglas B. West, of the University of Illinois. Features brief introductions, along with references cited. http://www.math.uiuc.edu/~west/openp/

Open Problems - Graph Theory and Combinatorics collected and maintained by Douglas B. West Number of problem pages now posted: 38 This site is a resource for research in graph theory and combinatorics. Open problems are listed along with what is known about them, updated as time permits. Individual pages contain such material as title, originator, date, statement of problem, background, partial results, comments, references. Also available is a Glossary of Terms Most pages in this directory have not yet been created; so far this is mostly a list of some well-known problems for which more detailed pages will be written later. Its accessibility at this early stage is a plea for contributed material to accelerate its development. The organization of topics roughly follows the four volumes of The Art of Combinatorics under development by D.B. West. Thus the four main headings are Extremal Graph Theory Structure of Graphs Order and Optimization , and Arrangements and Methods Alternatively, below is a direct search, courtesy of Google. The code provided no longer works as it should, but it has been modified to search in the domain www.math.uiuc.edu. Thus it will usually return some pages that you have no interest in, but it will also find problem pages under this one that contain your search term.
