This book constitutes the refereed proceedings of the 4th European Symposium on Algorithms, ESA '96, held in Barcelona, Spain, in September 1996.
The book presents 40 revised full papers selected from 124 submissions; also are included extended abstracts of two invited presentations. The papers included cover all research areas on algorithms and their analysis as it is carried out in the fields of computer science, discrete applied and algorithmic mathematics, operations research, and all other areas of algorithms-oriented research, design and analysis.

This book is a survey of the basic techniques for approximating combinatorial problems using parallel algorithms. Its core is a collection of techniques that can be used to provide parallel approximations for a wide range of problems, such as flows, coverings, matchings, traveling salesman problems, and graphs. For added clarity, the authors provide an introductory chapter containing the basic definitions and results. A final chapter deals with problems that cannot be approximated, and the book is rounded off by an appendix that gives a convenient summary of the problems described in the...

This book constitutes the refereed conference proceedings of the 8th International Conference on Algorithms and Complexity, CIAC 2013, held in Barcelona, Spain, during May 22-24, 2013. The 31 revised full papers presented were carefully reviewed and selected from 75 submissions. The papers present current research in all aspects of computational complexity and the use, design, analysis and experimentation of efficient algorithms and data structures.
