Regularity Properties of a Semismooth Reformulation of Variational Inequalities
Francisco Facchinei, Andreas Fischer, Christian Kanzow · SIAM Journal on Optimization · 1998
Variational inequalities over sets defined by systems of equalities and inequalities are considered. A new reformulation of the KKT conditions for the variational inequality as a system of equations is proposed. A related unconstrained minimization reformulation is also investigated. As a by-product of the analysis, a new characterization of strong regularity of KKT points is given.
