PhD/MPhil Students:

Very Large-Scale Constrained NonLinear Optimization

Together with Andreas Grothey we solved (May 2005) a large financial planning problem:
a quadratic program with 353 million constraints and 1010 million variables.

Matrix-Free Interior Point Method

Read about the Matrix-Free IPM (Oct 2009, published in COAP).
Survey on IPMs: IPMs 25 Years Later (Feb 2011, published in EJOR).
Theoretical background: Inexact Search Directions in IPMs (July 2012, published in SIOPT).
Application: Quantum Information (April 2012, published in J of CAM).

2nd Order Methods for Big Data (Convex, Unconstrained) Optimization

Read about the 2nd order method for solving L1-regularization problems (April 2014, published in Math Prog A).

Read about solving the Big Data optimization problem of size one trillion (2^40) (March 2015, published in COAP).

Software development:

  Linear, Quadratic & Convex Nonlinear Optimization with IPMs:
HOPDM (Higher Order Primal-Dual Method) is an efficient implementation of the multiple centrality correctors variant of the primal-dual method for large scale linear and convex quadratic optimization. An option to work matrix-free has recently been added to it. The earlier version of HOPDM is available for research use.

  Column Generation/Cutting Planes with IPMs:
PDCGM (Primal-Dual Column Generation Method) is an interior point based environment for decomposition and nondifferentiable optimization. The code is available for research use.

  Parallel Large-Scale Optimization with IPMs:
OOPS (Object-Oriented Parallel structure exploiting interior point Solver) is a new generation of software for optimization of unequalled computing power.
