摘要 | In this paper we propose an efficient and robust method for computing the analytic center of the polyhedral set P = {x is an element of R-n vertical bar Ax = b; x >= 0}, where the matrix A is an element of R-mxn is ill-conditioned, and there are errors in A and b. Besides overcoming the difficulties caused by ill-conditioning of the matrix A and errors in A and b, our method can also detect the infeasibility and the unboundedness of the polyhedral set P automatically during the computation. Detailed mathematical analyses for our method are presented and the worst case complexity of the algorithm is also given. Finally some numerical results are presented to show the robustness and effectiveness of the new method. |
