This book contains the papers presented at the 1989 Workshop on Algorithms and Data Structures, which succeeds the 1988 Scandinavian Workshop on Algorithm Theory. It presents current research in various areas of algorithms, computational geometry, geometric searching, VLSI placement and routing, graph algorithms, parallel algorithms, distributed algorithms, databases, and text searching.
