This book constitutes the thoroughly refereed post workshop proceedings of the 8th International Workshop on Approximation and Online Algorithms, WAOA 2010, held in Liverpool, UK, in September 2010 as part of the ALGO 2010 conference event.The 23 revised full papers presented were carefully reviewed andselected from 58 submissions. The workshop covered areas such asalgorithmic game theory, approximation classes, coloring andpartitioning, competitive analysis, computational finance, cuts andconnectivity, geometric problems, inapproximability results, echanismdesign, network design, packing and covering, paradigms for design and analysis of approximation and online algorithms, parameterizedcomplexity, randomization techniques, real-world applications, andscheduling problems.

This book constitutes the joint refereed proceedings of the 14th International Workshop on Approximation Algorithms for Combinatorial Optimization Problems, APPROX 2011, and the 15th International Workshop on Randomization and Computation, RANDOM 2011, held in Princeton, New Jersey, USA, in August 2011. The volume presents 29 revised full papers of the APPROX 2011 workshop, selected from 66 submissions, and 29 revised full papers of the RANDOM 2011 workshop, selected from 64 submissions. They were carefully reviewed and selected for inclusion in the book. In addition two abstracts of invited talks are included.APPROX focuses on algorithmic and complexity issues surrounding the development of efficient approximate solutions to computationally difficult problems. RANDOM is concerned with applications of randomness to computational and combinatorial problems.

Among the issues addressed are design and analysis of randomized and approximation algorithms, online algorithms, complexity theory, combinatorial structures, error-correcting codes, pseudorandomness, derandomization, network algorithms, random walks, Markov chains, probabilistic proof systems, computational learning, randomness in cryptography, and various applications.

This volume contains the papers presented at the3rd International Wo- shoponRandomizationandApproximationTechniquesinComputer Science (RANDOM'99) and the 2nd International Workshop on - proximation Algorithms for Combinatorial Optimization Problems (APPROX'99), which took place concurrently at the University of California, Berkeley, from August 8-11, 1999. RANDOM'99 is concerned with appli- tions of randomness to computational and combinatorial problems, and is the third workshop in the series following Bologna (1997) and Barcelona (1998). APPROX'99 focuses on algorithmic and complexity issues surrounding the - velopment of e?cient approximate solutions to computationally hard problems, and is the second in the series after Aalborg (1998). The volume contains 24 contributed papers, selected by the two program committees from 44 submissions received in response to the call for papers, together with abstracts of invited lectures by Uri Feige (Weizmann Institute), Christos Papadimitriou (UC Berkeley), Madhu Sudan (MIT), and Avi Wigd- son (Hebrew University and IAS Princeton).

Gegenstand dieses Lehrbuchs ist die Behandlung schwer losbarer diskreter Optimierungsprobleme. Im ersten Teil werden schnelle Algorithmen vorgestellt, die solche Probleme naherungsweise losen konnen. Der zweite Teil behandelt Komplexitatstheorie und Nichtapproximierbarkeit von Optimierungsproblemen. Das Lehrbuch enthalt zudem zahlreiche Anwendungsbeispiele, Ubungsaufgaben, Illustrationen und Abschnitte uber Grundlagen wie etwa die Turingmaschine.
