A New Full-Newton Step $O(n)$ Infeasible Interior-Point Algorithm for $P_*(\kappa)$-horizontal Linear Complementarity Problems [PDF]
In this paper, we first present a brief review about the feasible interior-point algorithm for $P_*(\kappa)$-horizontal linear complementarity problems (HLCPs) based on new directions.

Bad semidefinite programs: they all look the same [PDF]
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.

In this work, by considering a variety of realistic hardware impairments, we aim to enhance the security of a cooperative relaying network, where a source intends to transmit its confidential information to a destination in the presence of a group of ...

Incorporating a four-dimensional filter line search method into an interior point framework [PDF]
Here we incorporate a four-dimensional filter line search method into an infeasible primal-dual interior point framework for nonlinear programming.

Finding a point in the relative interior of a polyhedron [PDF]
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

Improved Full-Newton Step O(nL) Infeasible Interior-Point Method for Linear Optimization [PDF]
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.

On Simplex Pivoting Rules and Complexity Theory
We show that there are simplex pivoting rules for which it is PSPACE-complete to tell if a particular basis will appear on the algorithm's path. Such rules cannot be the basis of a strongly polynomial algorithm, unless P = PSPACE.

Fast Second-order Cone Programming for Safe Mission Planning
This paper considers the problem of safe mission planning of dynamic systems operating under uncertain environments. Much of the prior work on achieving robust and safe control requires solving second-order cone programs (SOCP).

The focus of this research is to apply primal-dual interior-point pathfollowing methods, specifically those derived from Newton’s method for solving convex quadratic semidefinite optimization (CQSDO) problems. In this paper, we present a numerical study
