Bai, Y. (author), Roos, C. (author)We consider nine elementary problems in optimization. We simply explore the conditions for optimality as known from the duality theory for convex optimization. This yields a quite straightforward solution method for each of these problems. The main contribution of this paper is that we show that even in the harder cases the solution needs...conference paper 2021

Gu, G. (author), Mansouri, H. (author), Zangiabadi, M. (author), Bai, Y.Q. (author), Roos, C. (author)We present several improvements of the full-Newton step infeasible interior-point method for linear optimization introduced by Roos (SIAM J. Optim. 16(4):1110–1136, 2006). Each main step of the method consists of a feasibility step and several centering steps. We use a more natural feasibility step, which targets the ?+-center of the next pair...journal article 2009

Bai, Y.Q. (author), Lesaja, G. (author), Roos, C. (author), Wang, G.Q. (author), El Ghami, M. (author)In this paper we present a class of polynomial primal-dual interior-point algorithms for linear optimization based on a new class of kernel functions. This class is fairly general and includes the classical logarithmic function, the prototype self-regular function, and non-self-regular kernel functions as special cases. The analysis of the...journal article 2008
