Stabilization of Mehrotra's primal–dual algorithm and its implementation
In this paper we apply a stabilization procedure proposed by Kovačević-Vujčić and Ašić to the Mehrotra's primal–dual interior-point algorithm for linear programming. Transformations of the dual problem corresponding to the stabilization procedure are considered. The stabilization procedure and...

Summary: | In this paper we apply a stabilization procedure proposed by Kovačević-Vujčić and Ašić to the Mehrotra's primal–dual interior-point algorithm for linear programming. Transformations of the dual problem corresponding to the stabilization procedure are considered. The stabilization procedure and Mehrotra's algorithm are implemented in the package
MATHEMATICA. A number of highly degenerate test examples are used to compare the modified Mehrotra's method with respect to the original one and the codes
PCx,
LIPSOL and
MOSEK. We also provide numerical results on some examples from the Netlib test set. |
