On the behavior of Lagrange multipliers in convex and nonconvex infeasible interior point methods [PDF]

open access: yesMathematical Programming, 2019
We analyze sequences generated by interior point methods (IPMs) in convex and nonconvex settings. We prove that moving the primal feasibility at the same rate as the barrier parameter $μ$ ensures the Lagrange multiplier sequence remains bounded, provided the limit point of the primal sequence has a Lagrange multiplier.

Convergence Analysis of the Inexact Infeasible Interior-Point Method for Linear Optimization [PDF]

open access: yesJournal 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 full-modified-Newton step infeasible interior-point method for monotone linear complementarity problem

open access: yesپژوهش‌های ریاضی, 2021
By using a new search direction, we propose an infeasible interior-point method for monotone linear complementarity problem. The algorithm uses only one feasibility step in each iteration, and we prove that it suffices in order to obtain a polynomial ...

A preconditioned inexact infeasible quantum interior point method for linear optimization

open access: yesComputational Optimization and Applications
Abstract Quantum Interior Point Methods (QIPMs) have been attracting significant interests recently due to their potential of solving optimization problems substantially faster than state-of-the-art conventional algorithms. In general, QIPMs use Quantum Linear System Algorithms (QLSAs) to substitute classical linear system solvers ...
