A good overview of combinatorial optimisation.......2001-04-20

Combinatorial Optimisation : Networks and Matroids by Eugene Lawler examines shortest paths, network flows, bipartite matching, non bipartite matching. More importantly there is an excellent introduction to matroid theory including matroids and the greedy algorithm, matroid intersections and matroid parity problems, some of these Lawler's own results.

However there is not much on NP completeness, since this book was published in 1976. For a more to date version of events in combinatorial optimisation one might want to look at Papadimitriou and Steglitz's book on combinatorial optimisation (quite old too, considering this was published in 1982), Ahuja, Magnanti and Orlin's book on Network algorithms, Hochbaum's book on approximation algorithms and Cook, Cunnigham,Pulleyblank and Schrijver's book on combinatorial optimisation (listed in the order they were published).

Book Description

A concise, comprehensive introduction to the topic of statistical physics of combinatorial optimization, bringing together theoretical concepts and algorithms from computer science with analytical methods from physics. The result bridges the gap between statistical physics and combinatorial optimization, investigating problems taken from theoretical computing, such as the vertex-cover problem, with the concepts and methods of theoretical physics.
The authors cover rapid developments and analytical methods that are both extremely complex and spread by word-of-mouth, providing all the necessary basics in required detail. Throughout, the algorithms are shown with examples and calculations, while the proofs are given in a way suitable for graduate students, post-docs, and researchers. Ideal for newcomers to this young, multidisciplinary field.

Book Description

Many physicists are not aware of the fact that they can solve their problems by applying optimization algorithms. Since the number of such algorithms is steadily increasing, many new algorithms have not been presented comprehensively until now. This presentation of recently developed algorithms applied in physics, including demonstrations of how they work and related results, aims to encourage their application, and as such the algorithms selected cover concepts and methods from statistical physics to optimization problems emerging in theoretical computer science.

Book Description

The past few years have witnessed a substantial growth in the number of applications for optimization algorithms in solving problems in the field of physics. Examples include determining the structure of molecules, estimating the parameters of interacting galaxies, the ground states of electronic quantum systems, the behavior of disordered magnetic materials, and phase transitions in combinatorial optimization problems.
This book serves as an introduction to the field, while also presenting a complete overview of modern algorithms. The authors begin with the relevant foundations from computer science, graph theory and statistical physics, before moving on to thoroughly explain algorithms - backed by illustrative examples. They include pertinent mathematical transformations, which in turn are used to make the physical problems tractable with methods from combinatorial optimization. Throughout, a number of interesting results are shown for all physical examples. The final chapter provides numerous practical hints on software development, testing programs, and evaluating the results of computer experiments.

Some new material.......2004-10-03

Traditionally, physicists haven't used many of the algorithms and ideas in computer science. The reason is simple. Computer science deals mostly with discrete items. Whereas most of physics uses continuum methods. But Hartmann points out in his book that there are indeed several classes of algorithms from computing that might be of utility to some physicists.

Percolation problems for example, are covered in a chapter. He shows how well known ideas from graph theory, like shortest path algorithms, can carry over usefully to attack thresholding in percolation clusters.

One chapter, on Monte Carlo methods, should already be familiar to some physicists. Ideas like simulated annealing came from physics. Plus, the Metropolis-Monte Carlo method was thought up by the well known Los Alamos physicist Nick Metropolis.

Hartmann does a commendable job in educating physicists about such ideas.

Book Description

Memetic algorithms are evolutionary algorithms that apply a local search process to refine solutions to hard problems. Memetic algorithms are the subject of intense scientific research and have been successfully applied to a multitude of real-world problems ranging from the construction of optimal university exam timetables, to the prediction of protein structures and the optimal design of space-craft trajectories. This monograph presents a rich state-of-the-art gallery of works on memetic algorithms. Recent Advances in Memetic Algorithms is the first book that focuses on this technology as the central topical matter. This book gives a coherent, integrated view on both good practice examples and new trends including a concise and self-contained introduction to memetic algorithms. It is a necessary read for postgraduate students and researchers interested in recent advances in search and optimization technologies based on memetic algorithms, but can also be used as complement to undergraduate textbooks on artificial intelligence.

Book Description

Synthesis and Optimization of DSP Algorithms describes approaches taken to synthesising structural hardware descriptions of digital circuits from high-level descriptions of Digital Signal Processing (DSP) algorithms. The book contains:

-A tutorial on the subjects of digital design and architectural synthesis, intended for DSP engineers,
-A tutorial on the subject of DSP, intended for digital designers,
-A discussion of techniques for estimating the peak values likely to occur in a DSP system, thus enabling an appropriate signal scaling. Analytic techniques, simulation techniques, and hybrids are discussed. The applicability of different analytic approaches to different types of DSP design is covered,
-The development of techniques to optimise the precision requirements of a DSP algorithm, aiming for efficient implementation in a custom parallel processor. The idea is to trade-off numerical accuracy for area or power-consumption advantages. Again, both analytic and simulation techniques for estimating numerical accuracy are described and contrasted. Optimum and heuristic approaches to precision optimisation are discussed,
-A discussion of the importance of the scheduling, allocation, and binding problems, and development of techniques to automate these processes with reference to a precision-optimized algorithm,
-Future perspectives for synthesis and optimization of DSP algorithms.

A wide body of literature exists covering separately the areas of DSP, hardware design, and design automation. This book brings together the fields, concentrating on those transformations, optimizations, and design techniques that would usually be considered to cross the domain boundaries between "pure DSP" and "pure digital implementation". As such, this book forms a valuable contribution to the existing literature.
Synthesis and Optimization of DSP Algorithms is of use both to researchers and students in the field of design automation for DSP systems, and to those wishing to implement state-of-the-art techniques within an Electronic Design Automation framework.

Great Book Club Resource.......2006-04-13

I just happened upon this little gem at my local bookstore and after thumbing through the pages for about a minute, I knew I had to have it. The layout of the book is superb as it highlights each of Miss Austen's novels and gives facts, fun lists and quotations in a light-hearted yet interesting manner. There is something for the long-time fan as well as anyone new to the novels. A must-have for any Jane Austen fan and a fantastic resource for any book club reviewing a Jane Austen novel. Well done.

A Friendly Source.......2006-03-01

Of all the references I have seen so far, this is the most complete as far as covering all of Jane Austen's personal life, the last 200 years of how other famous people saw her, a clear discussion of each of her novels, and how the many adaptations have had an impact in the late 20th and early 21st centuries. This book is must reading for oldtime fans of Jane and a great and full introduction for first time readers. Who can resist being a fan after reading this fine book? It deserves to be kept handy all the time.

A Sensible Resource.......2006-02-28

This fine little book is a great encyclopedia of Jane Austen, her life, all her works, impact on other writers, and on other forms of entertainment over the two centuries her works have been amongst us. I find it is frequently used as a resource for discussion. Those new to Jane Austen will get an excellent start in becoming a fan. The writing is lively, well illustrated and easily translated to the 21st century investigator.

Excellen Resource for Newbies and Diehard Fans Alike.......2005-10-03

The Friendly Jane Austen: A Well-Mannered Introduction to a Lady of Sense & Sensibility is a wonderful resource for the die-hard Austen fan as well as Austen newbies. Ms. Tyler takes each book in turn, gives a synopsis of the plot and places it in historical context and in the context of Austen's life. She then explains those details that might be abstract to those not familiar with Regency culture, such as entailed property, the importance of walking and the attitude toward marriage, making the reader comfortable with the novel. She includes illustrations, interviews, quizzes and delightful bits on the side such as "10 Surefire Ways to be Vulgar", a table of average income and "Sense and Sensibility: A Checklist". In addition, she finishes the book lists of movie versions, book spin-offs and sequels and shows Austen's role (her "legacy") in our century.

An Austen fan from way back, I found this a truly delightful book. Ms. Tyler is humorous as well as informative and her enthusiasm for Austen is apparent. This is a must-have for Austen fans, no question about it; the resources provided in The Friendly Jane Austen further the enjoyment of reading Austen's novels. It is also an excellent book for those that have just started reading Austen. With this book by your side, you can't fail to see just how wonderful Jane Austen was, and still is.

A literary romp with Jane.......2005-09-21

This was a truly fun book. It was written with a sense of fun about Jane Austen. Synopsis of the novels and characters are interspersed with interviews from actors who've had roles in movie adaptations of Jane Austen's novels, famous writers' thoughts on the impact of Jane Austen in their own writings, silly quizzes that will have you nodding your head or guessing out loud and even lists of the most obnoxious characters.
