9th European Workshop on Computational Geometry

March 18-19, 1993, Hagen, Germany

The European Workshop of Computational Geometry is an important scientific, annual event. Established researchers from academia, R&D people from industry, research students and postdocs come here together to discuss their most recent work and to establish new research projects and international cooperations.
The goal of this workshop is to provide an informal and productive atmosphere for scientific collaboration and to bring young researchers and established scientists together.
