Abstract

We give a new class of augmented Lagrangian functions for nonlinearprogramming problem with both equality and inequality constraints.
The close relationshipbetween local saddle points of this new augmented Lagrangian and local optimalsolutions is discussed.
In particular, we show that a local saddle point is a local optimalsolution and the converse is also true under rather mild conditions.
