  • Epstein ISE Department Seminar

    Tue, Sep 16, 2014 @ 10:00 AM - 11:00 AM

    Daniel J. Epstein Department of Industrial and Systems Engineering

    Conferences, Lectures, & Seminars


    Speaker: Dr. Victor M. Zavala, Assistant Computational Mathematician, Mathematics and Computer Science Division, Argonne National Laboratory Fellow, Computation Institute, University of Chicago

    Talk Title: "Advances in Large-Scale Nonlinear Programming: Theory, Computation, and Applications in Energy Systems"

    Abstract: We present advances in theory, computation, and applications of large-scale nonlinear programming. In particular, we present a new filter line-search framework (PIPS-NLP) for general nonconvex problems that does not require inertia (eigenvalue) information of the Karush-Kuhn-Tucker system to identify descent directions. Instead, the proposed inertia-free approach performs inexpensive curvature tests along computed search steps. We prove that the approach is well-posed, delivers descent directions, and is globally convergent. In addition, the inertia-free approach enables the use of a wide range of matrix-free and parallel linear algebra techniques and libraries that cannot provide inertia information. We demonstrate these capabilities by solving previously intractable problems that arise in natural gas and power grid infrastructures. These problems have millions of variables and constraints and result from the combination of stochastic optimal control, partial differential equations, and network features.

  • Epstein Institute / ISE 651 Seminar Series

    Tue, Sep 16, 2014 @ 03:30 PM - 04:50 PM

    Daniel J. Epstein Department of Industrial and Systems Engineering

    Conferences, Lectures, & Seminars


    Speaker: Archis Ghate, Associate Professor, Industrial and Systems Engineering, University of Washington, Seattle

    Talk Title: "Countably Infinite Linear Programs: Theory, Algorithms, and Applications"

    Series: Epstein Institute Seminar Series

    Abstract: In this talk, we will consider linear programs (LPs) with a countably infinite number of variables and a countably infinite number of constraints. These countably infinite linear programs (CILPs) arise in a variety of applications such as countable state Markov decision processes (MDPs), infinite-stage minimum cost network flow problems, non-stationary infinite-horizon planning problems, and robust optimization. Standard results, intuition, and interpretations in finite-dimensional LPs do not extend to CILPs. For example, weak and strong duality may not hold, extreme points may not be equivalent to basic feasible solutions, dual variables may not have a shadow price interpretation, and a finitely implementable Simplex algorithm is not known. In this talk, we will explore sufficient conditions under which such theoretical results and algorithms can be developed for CILPs. Several examples and counterexamples will be discussed to explain key ideas. Non-stationary infinite-horizon MDPs will be used as a flagship example where everything works out nicely.
