Abstract
Abstract: In this paper, we present a second-order corrector infeasible interior-point method for linear optimization in a large neighborhood of the central path. The in- novation of our method is to calculate the predictor directions using a speci c kernel function instead of the logarithmic barrier function. We decompose the predictor direc- tion induced by the kernel function to two orthogonal directions of the corresponding to the negative and positive component of the right-hand side vector of the centering equation. The method then considers the new point as a linear combination of these directions along with a second-order corrector direction. The convergence analysis of the proposed method is investigated and it is proved that the complexity bound is O(n 5 4 log "􀀀1).
