Since 1988 SWAT has been held biennially in the Nordic countries; it has a loose association with WADS (Workshop on Algorithms and Data Structures) that is held on odd-numbered years in North America. This 12th SWAT was held during June 21 23, at the University of Bergen in Norway. The conference focuses on algorithms and data structures.
