The author approaches this design problem by finding a subgraph of the original network that minimizes the common cost of all traffic in a Nash flow for this subgraph. Lester Hogan Professor of Computer Science, University of California, Berkeley “Recent trends in the analysis and design of computer networks take into account rationally selfish behavior by the network’s different components. This book provides a vivid glimpse into this area by dealing comprehensively with one of its well-studied problems. They are rigorous results from a mathematical perspective, but there are plenty of historical and empirical data that support them. This touches on several disciplines such as game theory, network flows, complexity analysis, approximation algorithms, and economics. Optimal and Nash flows are shown to be identical, but with different cost functions.

Twenty Lectures on Algorithmic Game Theory. Roughgarden’s work will be of interest not only to thdsis and graduate students in theoretical computer science and optimization but also to other computer scientists, as well as to economists, electrical engineers, and mathematicians.

Ubiquitous tools such as machine learning and optimization are already being used to address some of these challenges. The book therefore will not get the attention it needs from the latter class of people. Thanks to Michael Cheng for sending me many corrections and comments on an early draft. These bounds of course depend on the cost functions, and the author studies four versions of cost functions, namely where they are arbitrary, linear, polynomial, and “incline.


General network design with arbitrary cost functions, linear network design with linear cost function, Polynomial and Incline network design are considered with and without taxes.

This book also presents a link between computer science and economic theory.

An analysis of the loss in performance caused by selfish, uncoordinated behavior in networks. Alexa Actionable Analytics for the Web. This book introduces this exciting interdisciplinary type of analysis and presents some of its clearest and most influential applications. This proposal specifically focuses on roughgareen of these challenges: This work establishes a bridge between convex optimization and real algebraic geometry, which opens up orughgarden new and promising research area.

Chapter 3 describes the “worst possible” [the upper bound of the price of anarchy] ratio between the cost of a flow at Nash equilibrium and that of a socially optimal outcome. Graph Algorithms and Data Structures Volume 2. Read more Read less. I believe that this book is an easy reading for those acquainted with real analysis and optimization in Rn.

Sell on Amazon Start a Selling Account. For general cost functions and large networks, the conclusion reached is that Braess’s Paradox can be arbitrarily severe. This allows him to find upper and lower bounds on the severity of Braess’s paradox for the worst possible case. Theiss was a problem filtering reviews right now.


Tim Roughgarden – Wikipedia

The author realizes that such approximations may not exist for NP-hard problems, the author tries to find upper and lower bounds on C. ComiXology Thousands of Digital Comics. He then develops techniques for quantifying the price of anarchy with Pigou’s Example playing a central role. This is unfortunate since it is the network manager who typically needs to understand the issues and results discussed in this book.

PBC Library – Pairing-Based Cryptography – Ben Lynn’s PhD Dissertation

Roughgarden begins with a relatively nontechnical goughgarden to selfish routing, describing two important examples that motivate the problems that follow. AmazonGlobal Ship Orders Internationally.

Optimal and Nash flows are shown to be identical, but with different cost functions. They instead rely on intuition or some vague notion of commonsense to guide their decisions on bandwidth assignments, load balancing, and so on. Nowhere is the excitement, novelty, power, and elegance of these new ideas exemplified better than in Tim Roughgarden’s doctoral dissertation, which is the basis for this important book. Ships from and sold by Amazon. Many networks, including computer networks, suffer from some type of this “selfish routing.
