This book constitutes the refereed proceedings of the 4th International Symposium on Solving Irregularly Structured Problems in Parallel, IRREGULAR'97, held in Paderborn, Germany, in June 1997.The 18 revised full papers presented were carefully selected by the program committee for inclusion in the volume; also included are full papers by the five invited speakers. Among the topics covered are discrete algorithms, randomized methods and approximation algorithms, implementations, programming environments, systems and applications, and scheduling and load balancing.

This book constitutes the refereed proceedings of the 6th Annual European Symposium on Algorithms, ESA'97, held in Venice, Italy, in August 1998.The 40 revised full papers presented together with two invited contributions were carefully reviewed and selected from a total of 131 submissions. The book is divided into sections on data structures, strings and biology, numerical algorithms, geometry, randomized and online algorithms, parallel and distributed algorithms, graph algorithms, and optimization.
