multiobjective optimization and variational problems

Multiobjective Optimization and Variational Problems

Scope of the special session

The goal of this special session is to offer a review of research themes, methods, and open problems in optimization theory and variational problems, together with outlines of the new research trends. Topics of interest include (but are not limited to):

  • Variational problem
  • Equilibrium problem
  • Continuity, regularity and well-posedness of solutions
  • Duality theory
  • Multiobjective optimization
  • Non-regular optimization problems
  • Multicriteria optimization


  • Monica Milasi (University of Messina, Italy) -
  • Gabriel Ruiz-Garzón (University of Cadiz, Spain)
