Abstract
Based on the good computational results of the feasible version of the Mehrotra’s predictor-corrector variant algorithm presented by Bastos and Paixão, in this paper we discuss its complexity. We prove the efficiency of this algorithm by showing its polynomial complexity and, consequently, its Q-linearly convergence.
We start by proving some technical results which are used to discuss the step size estimate of the algorithm.
It is shown that, at each iteration, the step size computed by this Mehrotra’s predictor-corrector variant algorithm is bounded below, for n ≥ 2, by \(\frac{1}{200 n^4};\) consequently proving that the algorithm has O(n 4 |log(ε)|) iteration complexity.
