Research priorities

Guddat's main research interests were parametric nonlinear optimization , homotopy methods and operations research . Together with Dr. W. Gomez, P. Mbunga, Dr. D. Nowack, C. Solano, Prof. Dra. S. Allende (Universidad de la Habana), Prof. F. Guerra ( Universidad de las Américas , Puebla ), Prof. H. Th. Jongen ( RWTH Aachen ), Prof. Dr. J.-J. Rückmann ( Technische Universität Ilmenau ) he worked on the parametric optimization project funded by the German Research Foundation .

Editorial activities and international conferences

Guddat was co-editor of the series Approximation and Optimization , Peter Lang Verlag , Frankfurt a. M., Berlin-Bern-New York-Paris-Vienna. He served on the editorial boards of Yugoslav Journal of Operations Research, Journal of Convex Analysis, Revista Investigacion Operacional.

He was a member of the executive committees of the Parametric Optimization and Related Topics (V (1997 in Tokyo ), VI (1999 in Dubrovnik )) and Approximation and Optimization in the Caribbean (IV (1997 in Caracas ), V (1999 in Pointe-à- Pitre , Guadeloupe )), Chairman of the Program Committee International Conference on Operations Research (every two years in Havana , the 4th in March 2000). In total, Guddat organized more than 30 scientific conferences and also took care of their funding.
