Bad semidefinite programs: they all look the same [PDF]
, 2017 Conic linear programs, among them semidefinite programs, often behave pathologically: the optimal values of the primal and dual programs may differ, and may not be attained. We present a novel analysis of these pathological behaviors.

Convergence Analysis of the Inexact Infeasible Interior-Point Method for Linear Optimization [PDF]
Journal of Optimization Theory and Applications, 2008 This article studies the use of a primal-dual interior point method for solving large scale linear programs. The article begins with a presentation of the background to this problem and an overview of the existing literature, including the use of Preconditioned Conjugate Gradients (PCG) for inexact infeasible path-following algorithms.

A penalty barrier framework for nonconvex constrained optimization [PDF]
Journal of Nonsmooth Analysis and OptimizationWe consider minimization problems with structured objective function and smooth constraints, and present a flexible framework that combines the beneficial regularization effects of (exact) penalty and interior-point methods.

Finding a point in the relative interior of a polyhedron [PDF]
, 2007 A new initialization or `Phase I' strategy for feasible interior point methods for linear programming is proposed that computes a point on the primal-dual central path associated with the linear program. Provided there exist primal-dual strictly feasible

A Warm-start Interior-point Method for Predictive Control [PDF]
, 2010 In predictive control, a quadratic program (QP) needs to be solved at each sampling instant. We present a new warm-start strategy to solve a QP with an interior-point method whose data is slightly perturbed from the previous QP.

Improved Full-Newton Step O(nL) Infeasible Interior-Point Method for Linear Optimization [PDF]
Journal of Optimization Theory and Applications, 2009 The authors describe some improvements of the full-Newton step infeasible interior-point method (IIPM) for linear optimization introduced by C. Roos in 2006. The improved full-Newton step IIPM for linear optimization described in this paper can be seen as a homotopy method and has many interesting properties.
