This book constitutes the revised selected papers of the 43rd International Workshop on Graph-Theoretic Concepts in Computer Science, WG 2017, held in Eindhoven, The Netherlands, in June 2017. The 31 full papers presented in this volume were carefully reviewed and selected from 71 submissions.

This book constitutes the thoroughly refereed postproceedings of the 29th International Workshop on Graph-Theoretic Concepts in Computer Science, WG 2003, held in Elspeet, The Netherlands in June 2003.The 30 revised full papers presented together with 2 invited papers were carefully reviewed, improved, and selected from 78 submissions. The papers present a wealth of new results for various classes of graphs, graph computations, graph algorithms, and graph-theoretical applications in various felds.

The Second International Workshop on Parameterized and Exact Computation (IWPEC) was held in Zu ¨rich, Switzerland, during September 13–15, 2006. It th was organized as a component of ALGO 2006, which also hosted the 14 - th nual European Symposium on Algorithms, the 6 Workshop on Algorithms in th Bioinformatics, the 4 Workshop on Approximation and Online Algorithms, th and the 6 Workshop on Algorithmic Methods and Models for Optimization of Railways. This meeting was the second in the IWPEC series, with the ?rst having been held in Bergen, Norway, during September 14–16, 2004. The ?eld continues to experience rapid growth, in part due to its appeal as an alternative to tra- tional complexity theory, and in part due to the powerful practical applications it has spawned. IWPEC events are intended to cover research in all aspects of parameterizedand exact computation and complexity, including but not limited to new techniques for the design and analysis of parameterized and exact al- rithms, parameterized complexity theory, relationships between parameterized complexity and traditional complexity, applications of parameterized and exact computation, implementation issues and high-performance computing. A major goal is to disseminate the latest research results, including signi?cant work-- progress, and to identify, de?ne and explore directions for future study. The papers accepted for presentation and printed in these proceedings rep- sent a diverse spectrum of the latest developments on parameterized and exact algorithm design, analysis, application and implementation.

Parameterized complexity is currently a thriving field in complexity theory and algorithm design. A significant part of the success of the field can be attributed to Michael R. Fellows. This Festschrift has been published in honor of Mike Fellows on the occasion of his 60th birthday. It contains 20 papers that showcase the important scientific contributions of this remarkable man, describes the history of the field of parameterized complexity, and also reflects on other parts of Mike Fellows’s unique and broad range of interests, including his work on the popularization of discrete mathematics for young children. The volume contains several surveys that introduce the reader to the field of parameterized complexity and discuss important notions, results, and developments in this field.
