In this paper we replace such assumptions by new assumptions on the NLP problem, develop a modification of a primal-dual interior-point method implemented in software package LOQO and analyze convergence of the new method from any initial guess.}, number={1}, journal={Algorithmic Operations Research}, author={Griva, Igor and Shanno, David F. and Vanderbei, Robert J. and Benson, Hande Y.}, year={2008}, month={Mar.} }
