Passivity Enforcement Using an Infeasible-Interior-Point Primal-Dual Method

IEEE Transactions on Power Systems, 2008
Application of the network equivalent concept for external system representation in electromagnetic transient studies is well known. However, the challenge in application of an equivalent model, approximated by rational functions, is to guarantee passivity of the corresponding model.

On the Convergence of a Class of Infeasible Interior-Point Methods for the Horizontal Linear Complementarity Problem

SIAM Journal on Optimization, 1994
Summary: Interior-point methods require strictly feasible points as starting points. In theory, this requirement does not seem to be particularly restrictive, but it can be costly in computation. To overcome this deficiency, most existing practical algorithms allow positive but infeasible starting points and seek feasibility and optimality ...

Infeasible Interior Point Methods for Solving Linear Programs

1994
Interior point methods that follow the primal-dual central path of a dual pair of linear programs (P 0), (D 0) require that these problems are strictly feasible. To get around this difficulty, one technique is to embed (P 0), (D 0) into a family of suitably perturbed strictly feasible linear programs (P r), (D r), r ...

Infeasible interior point methods for sufficient linear complementarity problems

2009
In the first part of the thesis we focus on algorithms acting in the small neighborhood of the central path. We present a new first order corrector-predictor method for solving sufficient linear complementarity problems for which a sufficiently centered feasible starting point is available.

Infeasible Start Interior-Point Primal-Dual Methods in Nonlinear Programming [PDF]

, 1995
In this paper we present several infeasible start path-following and potential-reduction primal-dual interior-point methods for nonlinear conic problems. These methods are trying to find a recession direction of a shifted homogeneous primal-dual problem.

Large-Update Infeasible Interior-Point Methods for Linear Optimization

2011
Recently, C. Roos proposed a full-Newton step infeasible interior-point method (IIPM) for linear optimization (LO). Shortly afterwards, Mansouri and Roos presented a variant of this algorithm and Gu et al. a version with a simplified analysis. Roos' algorithm is a path-following method.
