F. Wu et al., On quadratic convergence of the O(root nL)-iteration homogeneous and self-dual linear programming algorithm, ANN OPER R, 87, 1999, pp. 393-406
In this paper, we show that Ye-Todd-Mizuno's O(root nL)-iteration homogeneo
us and self-dual linear programming (LP) algorithm possesses quadratic conv
ergence of the duality gap to zero. In the case of infeasibility, this show
s that a homogenizing variable quadratically converges to zero (which prove
s that at least one of the primal and dual LP problems is infeasible) and i
mplies that the iterates of the (original) LP variable quadratically diverg
e. Thus, we have established a complete asymptotic convergence result for i
nterior-point algorithms without any assumption on the LP problem.
