The 17th International Workshop on Well-Posedness of Optimization Problems and Related Topics will take place between 13-17 July 2026 in hotel “Samokov”, Borovets, Bulgaria. The workshop is organized by the Faculty of Mathematics and Informatics at Sofia University “St. Kliment Ohridski” and the Institute of Mathematics and Informatics at the Bulgarian Academy of Sciences, and is dedicated to the 70th anniversary of Julian Revalski.

The topics of the workshop include:

  • well-posedness, optimality and stability of problems in optimization;
  • calculus of variations, variational analysis;
  • optimal control and stabilization;
  • variational principles in optimization;
  • regularization techniques for ill-posed problems;
  • numerical optimization methods and their stable behavior under perturbations.

The workshop is held with the support of the International Center for Mathematical Sciences at IMI-BAS, the Ministry of Education and Science of the Republic of Bulgaria, and the Simons Foundation.
