The OLYMPIA project is carried out
by a complementary consortium of researchers in the area of nonlinear dynamical systems, dynamic programming, optimal control, hybrid dynamical systems and their applications. The theoretical expertise of the team members is combined by consolidating existing collaborations (some of them more than 10 years old) and creating new synergies.
The project members come from three units located in Nancy, Toulouse and Lyon.
