[0, 1] rather than xv ≥ 0, but the point is that an optimal solution of the linear program will never assign any of the variables xv a value strictly greater than 1, because the value of any such variable could always be reduced to 1 without violating any constraints, and this would...

o approximation algorithms that use randomization and linear programming (Section 35.4). • To allow more algorithms to appear earlier in the book, three of the chapters on mathematical background have been moved from Part I to the Appendix, which is Part VIII. • There are over 40...
There are several approaches to attack hard problems. All have their merits, but also their limitations, and need a large body of theory as their basis. A number of books for each one exist: books on complexity theory, others on approximation algorithms, heuristic approaches, parametrized complex...

"Introduction to the Design and Analysis of Algorithms" presents two important concepts clearly: PTAS and NPO-complete. This book also discusses the concept of NP-completeness before introducing approximation algorithms. Again, this is explained through examples which make sure that the students have ...
