This volume contains the Proceedings of the Twelfth French-German-Spanish
Conference on Optimization held at the University of Avignon in 2004. We
refer to this conference by using the acronym FGS-2004.
During the period September 20-24, 2004, about 180 scientists from around the
world met at Avignon (France) to discuss recent developments in optimization
and related fields. The main topics discussed during this meeting were the
following:
1. smooth and nonsmooth continuous optimization problems,
2. numerical methods for mathematical programming,
3. optimal control and calculus of variations,
4. differential inclusions and set-valued analysis,
5. stochastic optimization,
6. multicriteria optimization,
7. game theory and equilibrium concepts,
8. optimization models in finance and mathematical economics,
9. optimization techniques for industrial applications.
