TITLE: Online algorithms for constrained optimization

ABSTRACT:

Much of the literature on online optimization focuses on unconstrained minimization of objective functions with a large number of terms.  We are interested in extending this development to create online algorithms for convex optimization problems with large numbers of constraints.  We offer two approaches in this regard.  First, we combine random constraint sampling with the classical primal-dual algorithm.  Second, we combine random constraint sampling with classical penalty/barrier methods.  We are able to give a convergence rate analysis for both approaches.
