Research Goals:

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.

Test Problem Libraries:

bullet Mixed Integer Nonlinear Programming (MINLP)
bullet Mathematical Programs with Equilibrium Constraints (MPEC)
bullet Equilibrium Problems with Equilibrium Constraints (EPEC)
bullet Multiobjective Optimization Testproblems (MOOP)

Software:

bullet Dundee solvers for MINLP/NLP/QP
bullet MINLP solver on the NEOS server
bullet NLP solver on the NEOS server
bullet TOMLAB /MINLP, Matlab interface with sparse and dense versions of the Dundee solvers
