Sven Leyffer's Research

I am interested in the development of reliable methods for solving large-scale nonlinear optimization problems and in the implementation and analysis of filter type algorithms. This forms the basis from which I am extending nonlinear optimization methodologies to emerging areas such as mixed-integer nonlinear optimization and optimization problems with complementarity constraints.

• MacMINLP: Mixed Integer Nonlinear Programs
• MacMPEC: Mathematical Programs with Equilibrium Constraints
• Equilibrium Problems with Equilibrium Constraints
• Multiobjective Optimization Testproblems
