    Given a compact Lagrangian submanifold in flat space evolving by its mean curvature, we prove uniform $C^{2,\alpha}$ -bounds in space and C 2-estimates in time for the underlying Monge-Amp�re equation under weak and natural assumptions on the initial Lagrangian submanifold. This implies...

    Abstract. This paper investigates quasi-Newton updates for equality- constrained optimization. Using a least-change argument we derive a class of rank-3 updates to approximations of the one- sided projection of the Hessian of the Lagrangian which keeps the appropriate part symmetric (and...

    New first-order necessary optimality conditions with Lagrange multipliers for quasidifferentiable optimization with equality and inequality constraints are proposed. Kuhn-Tucker sufficient optimality conditions are also developed. Two kinds of differences for two convex compact sets, proposed by...

    We propose and study a new method, called the Interior Epigraph Directions (IED) method, for solving constrained nonsmooth and nonconvex optimization. The IED method considers the dual problem induced by a generalized augmented Lagrangian duality scheme, and obtains the primal solution by...

    In this paper, we design a new variable target value procedure, the trust region target value (TRTV) method, for optimizing nondifferentiable Lagrangian dual formulations of large-scale, ill-conditioned linear programming problems. Such problems typically arise in the context of Lagrangian...

  • Duality gaps in nonconvex stochastic optimization. Dentcheva, Darinka; Römisch, Werner // Mathematical Programming;Dec2004, Vol. 101 Issue 3, p515 

    We consider multistage stochastic optimization models containing nonconvex constraints, e.g., due to logical or integrality requirements. We study three variants of Lagrangian relaxations and of the corresponding decomposition schemes, namely,scenario,nodalandgeographicaldecomposition. Based on...

    This paper is devoted to the numerical resolution of unit-commitment problems, with emphasis on the French model optimizing the daily production of electricity. The solution process has two phases. First a Lagrangian relaxation solves the dual to find a lower bound; it also gives a primal...
