Algorithm Theory - SWAT '94

This volume constitutes the proceedings of SWAT '94, the 4th Scandinavian Workshop on Algorithm Theory, held in Aarhus, Denmark in July 1994. The SWAT events are organized each even year and alternate with the WADS meetings (Workshops on Algorithms and Data Structures) held each odd year in North America.
The volume contains 31 papers selected from a total of 100 submissions and 3 invited presentations by Michael Fredman (Rutgers), Johan Hastad (Stockholm), and Ketan Mulmuley (Chicago). The contributions cover algorithms and data structures in all areas of computer science and in discrete mathematics, particularly including graph theory, computational geometry, and databases.
