Abstract

In this paper, we are interested in the performance of Karmarkar's projective algorithm for linear programming. Based on the work of Schrijver, we offer a new displacement step better than Schrijver's one which led to a moderate improvement in the behavior of the algorithm shift. We show later that the algorithm converges after n1−log(2)+(nr210)log(ctenε)n1−log⁡(2)+(nr210)log⁡(ctenε) iterations.   This purpose is confirmed by numerical experiments showing the efficiency of the obtained algorithm, which are presented in the end of the paper.
