Opis

This volume presents papers from the 2nd Scandinavian Workshop on Algorithm Theory. The contributions describe original research on algorithms and data structures in all areas, including combinatorics, computational geometry, parallel computing and graph theory. The majority of the papers focus on the design and complexity analysis of data structures, text algorithms, and sequential and parallel algorithms for graph problems and for geometric problems.
