  • Abstract:

    Experimental discovery has long played an important role in research mathematics, even before the advent of modern computational tools. Many methods of antiquity are familiar to all of us, including the drawing of pictures to gain geometric insights and exhaustively solving similar problems in order to identify patterns. I will share a variety modern computational tools and techniques which I have used for my research at CARMA. The contexts of the discoveries will be varied -- including number theory, non-Euclidean geometry, complex analysis, and optimization -- and so the emphasis will be on the strategies employed rather than specific outcomes.

    Bio: Scott Lindstrom received his master's degree from Portland State University. In September, 2015, he came to CARMA at University of Newcastle as a PhD student of Jonathan Borwein. Following Professor Borwein's untimely passing, he has continued as a student of Brailey Sims, Heinz Bauschke, and Bishnu Lamichhane. In October he will begin a postdoctoral fellowship at Hong Kong Polytechnic University. His principal research area is experimental mathematics with particular emphasis in optimization and nonlinear convex analysis. He is a member of the AustMS special interest group Mathematics of Computation and Optimization (MoCaO) and organizes the Borwein Meetings for RHD students and postdocs at CARMA.

  • PHD CONFIRMATION SEMINAR
  • Speaker: Scott Lindstrom, CARMA, The University of Newcastle
  • Title: Experimental Variations on Convex and Non-Convex Optimization
  • Location: Room V205, Mathematics Building (Callaghan Campus) The University of Newcastle
  • Time and Date: 10:00 am, Mon, 15th Aug 2016
  • Abstract:

    We discuss ongoing work in convex and non-convex optimization. In the convex setting, we use symbolic computation to study problems which require minimizing a function subject to constraints. In the non-convex setting, we use a variety of computational means to study the behavior of iterated Douglas-Rachford method to solve feasibility problems, finding an element in the intersection of several sets.
